Proper plastic drying is essential for consistent injection molding quality. This guide explains drying requirements for common materials such as PP, ABS, PA, PC, PBT, and PET, including recommended temperatures, drying times, dew point control, and common mistakes that can lead to molding defects.

Silicone molds and injection molds serve different purposes in product development. Silicone molds are ideal for prototypes and small batches because they offer low tooling costs and short lead times, while aluminum and steel injection molds are better suited for larger production volumes. This guide compares their cost, lead time, mold life, material performance, and applications to help you choose the right molding solution.

Sourcing custom injection molding from China can reduce costs, but poor planning can lead to quality issues, unexpected costs, and delays. Learn the 7 common mistakes buyers should avoid, from incomplete RFQs and skipping DFM to ignoring T1 samples, material compliance, and quality inspections.
