Drake Plastics Ltd. Co., the global leader in ultra-performance polymer stock shape extrusion, is once again expanding its capabilities. To better serve machine shop and distribution customers, Drake has added precision waterjet cutting of blanks and 2D parts.
Read more →Polyamide-imides (PAI) are high performance polymers that combine excellent high temperature strength with low temperature toughness and impact strength while offering exceptional chemical resistance as an amorphous polymer to a wide range of common chemicals. They are closely related to two other high temperature aromatic imide polymers,
Read more →This paper is intended to help design engineers and those within the plastics industry supporting them select the process sequence and materials that maximize the performance of service critical parts. A great deal of folklore exists within the plastics community regarding the relative differences between machined and
Read more →Starting with the right size and shape based on final part geometry is critical when working with materials like Torlon®, PEEK and polyimides that are inherently expensive. Did you know that an extra .25” on a diameter can add 25% or more to the cost of your
Read more →High PV bearing applications are tough for even high-performance polymers like Torlon, PEEK and PPS. The reason is simple; frictional heat generated especially by the velocity component of “P x V” does not dissipate as easily as does in inherently more conductive bearing materials (i.e. metals). The
Read more →Ever hear from a customer… “I just started drilling and I heard a crack” or “I was sawing and melted plastic (swarf) stopped the blade” or “my inspection department found cracks in all my parts”. I can even tell you what the “mill” likely said… “They were
Read more →Producing parts from extruded stock shapes is preferred when injection molding is not practical, and many times for part performance reasons. Experienced plastics engineers have learned that the performance of a machined part can far exceeds that of an injection molded part, yet a comparison of resin
