Choosing the Right Material for Injection Molding – What’s Your Go-To?
Hey everyone! I’m working on a few small-batch parts and weighing my options when it comes to materials for injection molding. I’ve used ABS and polypropylene in the past, but I’m curious—what materials do you usually lean on for durability, precision, or even finish?
Also, how much does UV resistance or environmental exposure affect your decision if the part is used outdoors?
Would love to hear your experience or any tips you’ve picked up along the way. Thanks in advance!
