Mould Structure & Design Description

Core pins are functional mould elements that define holes, cavities, and internal product features. Their performance directly affects:

• Product dimensional accuracy

• Mould stability during repeated cycles

• Service life of the mould assembly

Design considerations include fit tolerance, concentricity, surface finish, and thermal stability, all customized according to customer drawings and mould structure.

Manufacturing Capability & CNC Machining Capacity

• CNC turning and milling for complex core geometries

• Precision grinding for diameter, roundness, and straightness

• Heat treatment control based on material specification

• Surface finishing to reduce friction and wear

• In-process and final dimensional inspection

• Flexible capacity for prototype and batch production

Custom Development & OEM Cooperation Process

1. Drawing or sample review

2. Material and tolerance confirmation

3. Machining and process planning

4. Sample production and inspection (if required)
