The HPS series is an entirely new type of automatic pelletizing press for high pressure input developed by RUISHENBAO Analytical (Shanghai) Co., Ltd to prepare high-quality pellets, which offers the full benefits of program-controlled sample preparation for x-ray fluorescence analysis.At present,the HPS pellet press is the only and first high pressure(60ton) press of sample preparation for XRF in market. There are two types for your requirement of which the operating pressure is individually up to 100ton and 120ton. A swing-out cross-head makes filling and cleaning of the die quick, simple and safe. A number of pressing variables can be selected, depending on the press tool employed. Precision press tools with a range of diameters and materials permit free pressing. Pelletizing parameters such as total pressing force, incremental increase and decrease of pressure as well as pressure holding time can be easily operated through a touch-screen LCD display. The pressure increase and decrease during pelletizing are controlled so that inner stresses within the sample are reduced. This allows the production of perfect pellets even with complicated sample material. The pelletizing process is controlled by the PLC program. This leads to substantial improvement in reproducibility of sample preparation and consequently more precise analysis results. The HPS pellet press is a high-quality, high pressure, precision and new engineering product with compact dimensions. It produces high-quality pressed pellets with mirrorlike surface necessary for optimal XRF results. It is ideally suited for laboratory requirements.

high pressure heating presses for consolidation - maschinenfabrik herbert meyer gmbh

The consolidation presses from Meyer are discontinuously working laminating lines for thermoconsolidation and provide significantly higher pressures than continuously working laminating machines. Our economic concept allows temperatures up to 400C. The materials to be consolidated are stepped through the line and thereby accurately heated, compressed with extreme pressures and cooled down again. These consolidation systems are especially suitable for thermoconsolidation of carbon layers and all materials which demand particularly high pressures at high processing temperatures.

The materials pass through a stepped process with several heating and cooling presses. This discontinuous process makes it possible to selectively heat, compress or cool the materials in the individual steps according to the requirements to obtain the desired end product. This process can be done from roll to roll or processing panel material.

AHV-S for SheetsThe laboratory presses AHV-S can also be used as a consolidation line to produce thermoplastic Organo-Sheets. Therefore we have developed a solution in which several AHV-S presses are combined to maximize consolidation of fiber-prepregs. The prepregs are stepped through the presses by means of a transport system and thus heated to the required temperature and controlled cooled down again. High specific pressures and high temperatures guarantee optimal results.

advances in the use of paris-edinburgh presses for high pressure neutron scattering - ios press

Paris-Edinburgh (PE) presses are nowadays the dominant high pressure devices for neutron scattering in the 10GPa range and above. Here, we present developments of gasket-anvil assemblies with 30% improved pressure performance and considerably increased lifetime compared to the currently used single-toroidal anvils, and giving nevertheless a similar signal-to-background ratio. We also present an improved Bridgman seal package which makes the low-temperature operation of the PE press significantly more reliable. Asystematic investigation of background sources in the equatorial scattering geometry is reported.

Since its development in the early 1990s, the Paris-Edinburgh press (cell) has become the main workhorse for neutron scattering in the 10GPa range, both at continuous and pulsed neutron sources [1,7]. The PE press is a compact hydraulic press with a mass of typically 30kg (for a VX5 type as used in the context of this study) and high capacity of some 100t [7]. It uses an opposed anvil technique first applied by Bridgman. For neutron scattering, the most widely used anvil geometry is a toroidal profile [6,13] with a central deepening to increase the sample volume (Fig.1). Over the past two decades, a single-toroidal profile and encapsulating TiZr gasket [11] with a sample volume of 50mm3 [12] has become a standard in many neutron sources. Such a sample volume is sufficient to obtain refineable diffraction patterns even on low-intensity sources such as SINQ (Paul Scherrer Institute, Villigen, Switzerland), if the sample is a reasonable neutron scatterer.

Acomplication arises in a scattering geometry where both the incident and diffracted beams pass through the gasket. This is the case in constant wavelength diffraction, for example, but also in inelastic neutron scattering on triple axes spectrometers. In this case, a significant amount of gasket and anvil material is in the direct beam, typically equivalent to the sample volume, and cannot be shielded properly. It generates a significant level of neutron background incoherent background from the TiZr gasket, reflections from the anvils, scattering from the pressure transmitting medium. These contributions drown small Bragg reflections of the samples and hence present a major limit for the data analysis. One aim of this study is to get a better understanding of the sources and composition of the background generated by the immediate sample environment. Another aim is an improvement of the pressure-load efficiency: The current single-toroidal anvils profile is able to generate 89GPa at a load of 100t which is not far from the upper limit of the VX5 PE press (max. load 130t) and its ancillary hydraulic equipment. At such loads, the life-time of cubic boron nitride (cBN) anvils is very short, typically 3 loadings, depending on the type of sample. cBN is a hard sinter material which produces no Bragg reflections due to the strong neutron absorption cross section of boron. Whereas this material is relatively robust to loadings of solid powders in standard pressure transmitting fluids like methanol-ethanol mixtures or NaCl, cBN anvils rarely survive loadings with gases. Also, the commercial availability of such anvils depends on a single company located in eastern Europe and alternative anvil material sources would therefore be highly desirable. Finally, the low-temperature operation of the PE cell is currently not optimal. The current design [7,9] of the Bridgman seal for the compressed He gas as the pneumatic fluid to drive the piston often starts to leak below 120K which terminates frequently measurements at low load.

This paper reports significant improvements concerning these three issues. They grew out of a development program supported by ILL through 5 days of beam time at the D20 high intensity diffractometer over the period 20162019, as well as financial support from the SINE2020 Sample Environment work package.

All diffraction data shown here were obtained at D20 using a VX5 PE press in air (without cryostat). Figure1 shows schematically the general setup of the D20 diffractometer. Most important features are (a)a vertically focusing monochromator (not shown), (b)a microstrip detector which covers 160 degrees in 2-theta, and (c)an oscillating radial collimator (ROC) which removes unwanted background in the immediate environment of the sample. More specific details can be found in [5]. Horizontal and vertical collimation of the beam is achieved by diaphragms in the evacuated beam tube and by 2mm thick Cd slits at the front of the nose whose distance to the sample position can be adapted to the experiment. In all tests reported here, the position of the nose was set to 160mm (corresponding an operation of the PE cell in its cryostat), the vertical slit size to 20mm, and the horizontal slit size to 6 and 8mm, which is adapted to a sample of 4 and 6mm, respectively. The vertical slit size is adapted to the vertically focusing monochromator which has a height of 300mm and is located 3200mm from the sample position.

In many cases we used -Fe2O3 (hematite) as test sample. Hematite is a crystal with typical scattering power. It shows several magnetic reflections at low scattering angles and a spin-flop transition at 2GPa (Morin transition) which can be used as a sensor for non-hydrostatic conditions [10]. Its equation of state is well known [3] and it can hence be used as a pressure marker.

Schematic setup of the flightpath at D20 between monochromator (left, not shown) and the sample. Numbers give distances in mm with respect to the sample position. The vertically focusing monochromator (height of 300mm) is located at 3200mm distance from the sample.

Figure2 shows drawings of the anvil profile and corresponding encapsulating gaskets [11] which are a result of the SINE2020 development program and to which we refer in this paper. The profile resembles closely to what is known as double-toroidal profile (which has been used for neutron scattering to 25GPa [8]) where the outer toroid has been removed. The starting material of such anvils are wire-drawing sintered diamond dies of type WD960C from Sumitomo. These are smaller than the currently used COMPAX5913 sintered diamond dies from Sandvik Hard Materials and consequently less expensive. Due to the smaller grain size, their hardness and toughness is also superior.

Top row: anvil profile (left) and corresponding gaskets (right) for sintered diamond anvils presented in this work (SD SINE anvils). Bottom row: standard single-toroidal profile & gaskets for comparison.

To investigate the sources and composition of background, SINE anvils were used with TiZr gaskets and a mixture of MgO and NaCl as sample. Figure3 shows patterns obtained with (a)shutter closed, (b)shutter open but beam blocked at r= 320mm by 15mm B4C plates plus a 2mm Cd sheet, (c)beam on anvils (no gaskets), (d)beam on anvils+ gasket, and (e)beam on anvils+ gasket+ sample+ pressure transmitting medium (PTM, 4:1 deuterated methanol-ethanol mixture). Note the three strong reflections produced by diamond of the sintered diamond anvils. The anvil gap was in each case 1.6mm (measured with a gauge or given by the gasket dimensions) which is the situation at 0GPa, and the conical faces of the anvils were covered by 0.3mm thick Cd sheets up to the interface between WC and sintered diamond (diam. 16mm).

Diffraction patterns accumulated for 15 minutes each, at different configurations. From bottom to top: shutter closed, shutter open but beam blocked at r= 320mm (Fig.1), only anvils, anvils+ empty gasket, anvils+ gasket+ sample+ PTM.

From these data, it becomes clear that the instrumental background (i.e; beam on up to r= 320mm) represents approximately 15% of the total background. It is similar in size to the contribution of the anvils and the PTM. The major source of background is clearly the TiZr gasket which produces more than half (60%) of the observed neutron background.

In an attempt to reduce the background of the gasket, various tests with improved horizontal collimation close to the sample were conducted (the vertical collimation is guaranteed by the Cd shield on the conical surface of the anvils). The most efficient horizontal collimation was a Cd collimation of 4.5mm width at a distance of 10mm from the sample position which reduced the background by approximately 10%, i.e. only insignificantly. The conclusion of these tests was that the collimation implemented on D20 (diaphragms+ collimation nose) is already rather efficient and can only be marginally improved. Additional horizontal collimation would necessarily be located as close as possible to the sample and hence be attached to the anvils or the load frame. Such a device would however reduce flexibility since it would exclude a change of rotation angle of the pressure cell with respect to the incident beam. Future improvements could include the development a ROC with smaller gauge volume or some collimation on the diffracted beam side, close to the sample.

The SINE anvils allow only a 50% smaller sample volume compared to the standard single-toroidal anvil profile, i.e. 30 versus 50mm3. But since the amount of TiZr is also reduced as well as the absorption of the neutron beam due to the reduced gasket dimensions, the signal-to-background ratio was expected to remain approximately equal.

Comparison of a diffraction pattern of Fe2O3 collected with cBN anvils with standard geometry (50mm3 sample volume, blue) and with SINE anvils (30mm3, red), at low (01GPa, upper panel) and high pressure (6.4GPa, lower panel). The lines through the data (dots) are Rietveld fits. Note that 3 Bragg reflections from diamond were excluded in the red patterns. Accumulation time is 20 minutes in each case.

This is demonstrated in Fig.4 which shows diffraction patterns of Fe2O3 at low pressure 1GPa, in cBN anvils with 50mm3 sample volume, and SD SINE anvils with 30mm3 sample volume. The signal-to-background ratio (averaged over all reflections) is very similar for both cases, independent of the pressure (compare upper and lower panel), and might be even more favorable for the latter setup. The only disadvantage appears to be the presence of three strong Bragg reflections of diamond from the anvils. ARietveld analysis of the pattern where the 3 diamond reflections were excluded show very similar statistical errors on the refined structural parameters. Table1 gives the refined crystallographic parameters including estimated standard errors (in brackets) which confirm that the precision obtained in the two type of anvils are very similar.

It should be noted that anvils made of SD are obviously more transparent to neutrons than cBN anvils. For the WD960 dies used to machine the SINE anvils, the absorption length for = 2.0 neutrons is approximately 8mm [7], whereas for cBN it is 0.1mm at most. For a given anvil geometry and a given gap between the anvils it means a slightly larger neutron window for SD anvils and hence an increased signal. The gain will be larger for SD anvils with SiC instead of Co binder for which the absorption length is about 50% larger [7]. Since SiC-SD dies are not easily available, expensive to machine, and with mechanical properties likely to be inferior, Co-containing WD960 were used to machine the SINE anvils reported here.

Refined structural parameters of -Fe2O3 (hematite) in single-toroidal anvils cBN and SINE anvils, at low and high pressure (hexagonal setting; is the angle of the spin with respect to the c-axis, m is the magnitude of the magnetic moment)

This was measured in two runs using a mixture of MgO and NaCl in the first loading and Fe2O3 in the second loading, both with 4:1 methanol-ethanol PTM. The pressure was determined from the known equations of state of NaCl [2], MgO (Birch-Murnaghan equation with B0= 160GPa and B= 4.2 [4]), Fe2O3 (BM equation with B0= 201GPa, B= 4.3 [3]). In the run with MgO+NaCl, the quality of the diffraction patterns above 9GPa degraded, most likely due to the freezing of the PTM. As a result of this, the pressure reading (by Rietveld refinement) from the MgO became less reliable, and the pressure values derived from NaCl appeared to increase more rapidly with load. The plot of Fig.5 shows also a comparison with standard single-toroidal anvils made of cBN (dashed line). There is a 30% increase in pressure efficiency which is obviously an effect of smaller gasket dimensions.

Pressure-load characteristics of SD SINE anvils derived from two loadings with (NaCl+MgO) and Fe2O3, both with 4:1 methanol-ethanol PTM. The dashed line is the typical behavior for standard single-toroid anvils [7].

There is some limited information on life time of SD SINE anvils. From a total of 8 loadings, all of them to pressures above 8GPa, three suffered a violent blow-out. One of them occurred in the upstroke and was a result of overloading the sample space, or a gasket which was too thick. The two others occurred during decompression of the samples shown in Fig.5 at a load of 28t. All of the anvils survived without any visible damage. We attribute this robustness against blow-outs to the superior hardness of SD compared to cBN, combined with the fact that the forces on the anvils are generally smaller with the SINE anvils. If this trend is confirmed, routine operation with SD SINE anvils may be less expensive than with cBN anvils, despite their considerably higher initial costs (approximately 2000versus 1000per anvil).

The ILL low-temperature PE press uses compressed helium as a pneumatic fluid which needs a special seal between the gliding piston and the cylinder. This is a well-known technical challenge given the very low viscosity of helium. In the PE press, it is so far achieved by a Bridgman unsupported seal using a Teflon-Pb-Teflon sandwich with 0.520.5mm thickness [9]. Experience over the last 10 years of user operation show that such as seal is perfectly leak tight from ambient temperature to approximately 130K. But below, small leaks occur frequently at low load (pressure) which often cannot be compensated by the compressor. To improve its reliability, an additional layer of indium was inserted between two separated Pb seals to give a Teflon-Pb-In-Pb-Teflon sandwich with thickness as shown in Fig.6.

Low temperature piston (left) of PE VX5 press with its improved Bridgman seal (middle and right). The picture shows the seal after repeated compression to 80t at 300K. The layers of Pb and In are not distinguishable.

Initial laboratory tests of this seal in the range 77300K showed perfect leak tightness at ambient temperature and no leak down to 90K if the gas pressure remains above 80bar (6t load, approximately 0GPa for use with SINE anvils). An increase in load to 200bar at this temperature did not result in leaks, as expected. Asubsequent decrease in load at 95K led systematically to a leak at 100bar. Such a behavior is typical for Bridgman seals, i.e. leak tightness in the upstroke and occurrence of leaks on pressure release. Further tests were then carried out with the ILL VX5 and its associated cryogenic equipment. With an initial He gas pressure of 200bar applied at 300K, no leaks were detected down to 5.3K.

Background: The major source of background in neutron scattering in the equatorial plane of the anvils is from the incoherent scattering of the TiZr gaskets. Our data show that there is limited means for improving this, at least at D20. Abandoning null-scattering TiZr as gasket material would be an interesting possibility to explore, in particular for measurements using relatively long wavelengths (23), where there are no Bragg reflections at small scattering angles (large d-spacings).

Anvils: The anvil set up presented here (SINE anvils) has clear advantages compared to the currently used single-toroidal cBN anvils: (a) 30% higher pressure-load efficiency at comparable signal-to-background level, (b)availability of raw dies, (c)increased life-time and possibly lower costs in long-term use. The additional scattering from diamond seems to be a minor problem. The availability of such anvils would allow the use of smaller PE load frames, for example the 10kg (mass) VX1 press. With its 50t capacity it would allow pressures of 8GPa with the same anvils (Fig.5).

Rosin is also uniquely versatile in the fact that it can be manipulated into almost any type or texture of concentrate. From shatter and sugar to budder and wax, rosin has many adaptability options, making it an awesome product for extraction artists to experiment with.

The heat from the plates loosens the resinous glands, or trichomes, that contains all of the plants cannabinoids while the pressure effectively squeezes it from the flower. This basic process is the foundation for rosin presses and the technology that makes them run.

Since rosin is produced without the use of solvents, which can change the flavor and finished product, its preferred by users who dont want any chance of having lingering, man-made chemicals in their concentrates.

The very best rosin, referred to as live rosin is pressed from plants that are freshly harvested, thereby maximizing the integrity of the cannabinoids and terpene compounds which collectively as an entourage effect help create a superior high when compared to more harsh extraction processes.

This extraction technique has been used by other industries for thousands of years. Imagine squeezing the oil out of olive or the juice from a grape. The rosin process presses the starting material until it produces a potent, solventless concentrate.

If your flowers, dry sift, or hash is terpene-rich, a lower temperature is needed. This is because the terpenes squeezed out of the trichome glands during the initial press act as a natural solvent to facilitate the rosin process.

You may think that more heat will result in larger yields. This is not true! Using too much heat will burn off terpenes and other compounds that make rosin so sought after. You should stick to lower heat.

The pressure needed will depend on the temps you use, but, also on what youre pressing. Flower needs more pressure, somewhere between 600-1000 PSI. Dry sift/kief or hash will require less pressure because it is more concentrated. You should shoot for between 300-800 PSI.

*Because pressure requirements will change depending on the temperatures you use, the specific flower being pressed, and the volume, it is useful to look for rosin presses that have fine-tunability when it comes to exact pressures.

Rectangular plates work best. The ideal plate structure of a rosin press is longer and narrower. This is because this shape maximizes the perimeter of your press. A rectangular plate will normally outperform a square one.

The cannabis industry is a tight knit one, not just because the law forces it to be, but because fundamentally cannabis is a communal herb and therefore it makes sense to also support local/domestic equipment manufacturers whenever possible.

With quality indicators out of the way you should start thinking about the volume of plant material you plan on processing in the next 1-5 years because there is no harm in buying a press that you can grow into.

Typically entry-level presses are manual presses and pressure is generated by a pull-down lever or through a twist-operation. Manual presses are going to be the best bang-for-buck options in the $300 price range.

Dont let our emphasis on price scare you away from the Ju1ceBox manual press. This little guy is popular with small-time extractors and DIY enthusiasts alike because of its simplicity, versatility, and well, affordability.

The lightweight heat press machine by Taidda is compact, weighing less than 10 pounds, but that doesnt mean its lacking in any way. The double heat plate is easy to operate chances are youll figure it out without even needing to read the manual.

In terms of features, there really arent too many outside of the rubber grip handle and timer. This press isnt designed for commercial applications and is more of a hobbyist/DIY extraction tool for home growers and enthusiasts to experiment with.

Hydraulic rosin presses are probably the most common type of rosin press on the market. As opposed to manual pressing, these use hydraulic pressure, generated either by a hand pump, foot pump, or even an electric pump. These can be used by both home growers and commercial extractors.

This press features 6x10 food-safe aluminum plates and PID temperature controls that maintain a high thermal mass for consistent temperature. Its equipped with a power frame capable of withstanding the whopping 25 tons of force this thing delivers.

All of that pressure and the precision heating allow you to press at the lowest temperatures and preserve rich, valuable terpenes. This is a hybrid press and can be operated via hydraulic hand pump, pneumatic foot pump or with an electric pump. All of which are, unfortunately, sold separately.

On top of having one of the best names, the Sasquash V2.0 can press up to two ounces of flower at once! It features huge 10 x 5 dual heated plates, and provides over 25 tons (10,000 psi) of pressure.

Nugsmasher presses are most popular for home DIY types and those looking to extract from their own personal grow operations. The hobbyist-friendly price points and the all-in-one solution design is what makes these popular with home growers.

This isnt to say a small cultivar couldnt also use Nugsmasher presses, as they do have units of varying sizes and pressures, including a massive Nugsmasher Pro that would be perfect for a boutique rosin company looking for a reliable piece of equipment to help establish their new brand.

Nugsmahser sells bundles which is why they are popular as plug-n-play solutions. These bundles or extraction kits have everything you need including the press, extraction bags of varying sizes, a rosin collection plate, tools, molds, and containers for finished product.

*Bonus Inclusion: Rosinbomb Rocket and Rosinbomb M60 presses are often held in the same regards as Nugsmasher, both being made in the USA and both having fiercely loyal fan bases among growers and extractors.

Pneumatic Rosin Presses are top of the line Rosin Presses that use a pneumatic cylinder that requires no oiling or maintenance and through their unique design are able to achieve 5 to 25 tons of pressure with the use of an air compressor.

These industrial machines are capable of pressing high volumes all day every day. If the hand presses are handguns and the hydraulics are rocket launchers then these are full blown tanks, capable of obliterating any flower yield with ruthless efficiency and precision.

The ultimate rosin press, built for true commercial capabilities, and now with a fully automated upgrade option. Based on the award winning Pikes Peak, the Longs Peak offers twice the processing output and 60% more force for incredibly consistent results at high volume.

Electric rosin presses are great because they dont require a pump that can take up extra space just plug it into a wall. This style of rosin press is sort of new to the extraction industry, but is quickly gaining favor, especially with hobby growers and home extractors.

Sure, you cannot process as much volume as the abovementioned hydraulic and pneumatic options but for those small boutique companies focused on providing the absolute highest quality extracts these little guys make a great option.

The small form factor also makes them PERFECT for research and development as you dont have to dedicate a large space on your production floor to a giant extractor, these can usually fit neatly in the corner of an existing work bench.

The new Electric Heat Press eliminates the need for a pneumatic compressor. This plug and play, user-friendly heat press puts you in full control with its built in electronic pressure controller. The Electric Heat Press gives off a sleek and clean design that is perfect for any work space.

Choosing the right press comes down to your business or personal goals. If you are looking to expand to dominate your states market, then wed recommend sticking with hydraulic and pneumatic options as they are the most reliable and bullet-proof options.

One thing for sure is these are all well-built machines that will last, and since the cannabis extracts market is only continuing to grow at lightning speed youre pretty safe off buying just about any sized press because it wont be too hard to sell it used when the time comes to upgrade.
