Selective Laser Sintering SLS is close to be accepted as a production technique Additive Manufacturing. However, one problem limiting employment of SLS for additive manufacturing in a wideranging industrial scope is the narrow variety of applicable polymers. The commonly applied SLS powder to date is polyamide 12 PA 12. PA 12 or ccompounds of PA 12 dry blends are approximately 90 of

Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder. At Ancos, we can achieve a range of desired size distributions to meet specifications, from coarse to fine.

CUSTOM POWDERS. COTENE . Cotene is the trade name for a new range of high quality, thermoplastic coating powders designed to provide extraordinary corrosion protection for metal parts under harsh environmental conditions. Cotene will form a strong adhesive bond without the use of a metal primer. Cotene is used when standard coating materials are not capable of performing the job.
Size Reduction. A major step in the polymer development procedure occurs when the individual resin pellets are ground to a fine powder. For that reason, the choice of polymer grinding techniques becomes a vital component of the overall process.
Dry grinding mills are wellsuited to metal powder requirements such as homogeneity of the mixture, uniformity of the morphology and relatively narrow particle size distribution. Milling offers a number of advantages over atomization, the other major production method for metal powder.
Each supplier has its own method to prepare polymer powder, Monsheimer said. It can be grinding, precipitation or other suitable methods. We have been using precipitation to produce powders for powder bed fusion processes for decades and have proven to be able to supply material in a consistent high quality and in the volumes needed.
Cryogenic Fine Grinding of Rubber from Used Tires. Superfine powdered rubber can be manufactured efficiently using a cryogenic process. Liquid nitrogen is employed to cool the feed granules below their glass transition temperature before they are pulverized with counterrotating pin mills.
Polymer powders produced by cryogenic dry grinding 2,4,5 are 7 available, too, however, they often show poor processabilitydue to the bad flowability of the typical irregular shaped particles obtained by comminution processes .
Highlights Polymer particles below 5 m are produced by wet grinding at reduced temperatures. The approach is even applicable to PEEK with high fracture toughness. Higher stirrer speed and lower temperature reduces final particle size and enhances kinetics. Appropriate choice of solvent viscosity avoids viscous dampening of bead motion.
Polymer powder can be preheated before placing it in the tool by the rejected process heat or from compressors if located nearby. All plastics have a low heat transfer coefficient and take time to heat up. Preheating even by a small amount will reduce the energy input necessary and therefore the cycle time.
In order to produce fine polymer powders, a special and unconventional cryogenic grinding system was established using liquid nitrogen, where a jetvortex mill was used as the grinding mill. The major feature of this grinding process is that heat generation during the grinding period was eliminated.
Midwest Elastomers, Inc. is committed to the processing of high quality, finely ground plastics and rubber materials serving industrial and commercial markets that demand strict specifications. Some of our other core services include playground tiles, Flexithane, Cryogenic Grinding and Polypropylene powder.
Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor. An additional benefit of cryogenic milling in an internally agitated ball mill is the ability to fully immerse the product in liquid nitrogen during milling.
