Best injection molding plastic for plastic enclosure
Hi everyone, we’re talking about a snap-fit design for a small electronic enclosure that needs to be opened and closed frequently—about 20 cycles per week. The part should be injection molded, and I’m deciding between polycarbonate (PC) and an ABS/PC blend. The material needs to handle repeated stress without cracking or stress whitening, provide good impact resistance, and remain dimensionally stable in temperatures up to 70°C. For those with experience in similar projects, which material has worked best for long-term reliability under these conditions?
