Introduction: Low-volume runs are useful for new product introduction, design verification, assembly checks, and market evaluation. The purpose is to confirm the product and process before scale-up, not to replace production criteria with temporary conditions.
Suitable stages: Design verification after initial samples, engineering-change validation, new material or color trials, and low-volume confirmation before production launch.
Introduction: SHIYUNJIA supports trial and production molding for reviewed plastic component programs. Before production, both sides should agree material, color, approved sample, cosmetic criteria, critical dimensions, packing, and lot requirements.
Introduction: The first mold trial is not simply about producing a part. It is used to check mold movement, molding behavior, appearance, dimensions, and assembly. Material, sample quantity, critical checks, and the customer's approval method should be agreed before the trial.
