Mould Structure & Design Description

Guide pins and bushings are critical alignment elements within injection mould assemblies. In bottle cap moulds, they ensure accurate positioning between the core and cavity plates during mould opening and closing. Proper material selection and machining accuracy help minimize misalignment, reduce wear, and maintain consistent mould performance throughout extended production runs.

Manufacturing Capability & CNC Machining

Senlan Precision applies advanced machining and inspection processes to guarantee dimensional stability and surface quality. High-precision machining centers from MAKINO and turning and grinding equipment from HARDINGE are used to meet tight tolerance and concentricity requirements.
