From Solvay Advanced Polymers
You design a part, build prototype tooling and test the prototype parts. You're going to get exactly the same part from the production tool . . . correct? Not necessarily. The transition from prototype tool to production tool can be fraught with problems. There's a wide gamut of issues that must be considered, including construction materials, gate design, venting, and runner design. Sometimes, you'll know after the first shot in the production tool that you have problems because the tool failed to fill properly, shrinkage rates varied from prototype tests, parts warped, or cosmetic surfaces were marred by sink marks. And then again, you might not discover damaging problems until four to six months later when you get a call at 4 a.m. from your QC manager in Souchou, China. Products & Services
