Mould Structure & Design Description

Injection molding pins in multi-cavity moulds must maintain consistent length, straightness, and surface condition to ensure synchronized ejection. Poor pin matching can lead to uneven part release, increased wear, or mould damage. Senlan Precision focuses on controlled machining and batch consistency to ensure all pins within a mould set are dimensionally well-matched and perform uniformly throughout production.
