Mold Structure & Design Description

Custom mold parts such as inserts, cores, and line-A pieces function as critical forming and alignment elements within injection molds. Design considerations typically include:

• Accurate mating surfaces to ensure cavity alignment

• Controlled clearances for consistent plastic flow and part quality

• Structural stability under high injection pressure

• Modular design for quick replacement and reduced downtime

Senlan Precision manufactures strictly according to approved designs without design modification unless requested.
