Injection Molding Tutorial: Videos

WHAT IS INJECTION MOLDING?
Every day of our lives, each of us is surrounded by plastic parts produced by the process of injection molding. Examples are everywhere, and include keyboards, tooth brushes, car components, toys, television components, make-up packaging and all kinds of products used in the medical industry. At Craftech Industries, we injection mold a large variety of plastic fasteners and custom parts. We uncovered a video by Bill Hammack at the University of Illinois which does a thorough job of explaining what injection molding is. … Read more

Acetal, Delrin AF and PTFE: Plastic Bearing Materials

Three of the most useful plastics for making bearings are Acetal, Delrin AF® and PTFE.  Acetal and Delrin AF® are both thermoplastics; meaning that these materials can be heated into a liquid form and then cooled into a solid retaining the shape of either the extrusion nozzle or the mold used to shape it. PTFE has the lowest friction constant of any plastic material. It is not a thermoplastic but it can be extruded.Read more
