Here at our shop, there are a great deal of projects that have revolved around our ability to machine, weld and make use of the varieties of plastics out on the market. UHMW (Ultra High Molecular Weight Polyethylene) is our go to when surfaces can’t be scratched. Our plating tanks are made from Polypropylene due to the highly corrosive solutions used in those types of processes. Polypro is also used when we have a food grade specification to follow, or even UHMW if a fixture or jig is necessary. Most of our 80/20 guards have custom fit Lexan panels to minimize the risk of injury to an operator or surrounding workers from flying parts or debris. Delrin is another great plastic to use for 3D machining when surface appearances aren’t as critical or when shape and deflection become any important characteristic that we are looking for in a fixture or jig.
