Mould Structure & Design Description

Multi-cavity mould parts require precise dimensional alignment between cavities to ensure consistent filling, cooling, and part ejection. Fine surface grinding is applied to critical contact and fitting surfaces to improve flatness, parallelism, and surface integrity. These processes help reduce mould wear, improve assembly accuracy, and maintain stable production over extended cycles.

Manufacturing Capability & CNC Machining

Senlan Precision is equipped with high-precision machining and finishing equipment to support multi-cavity mould part production. Advanced machining centers from MAKINO and precision equipment from HARDINGE are used to achieve consistent machining accuracy and controlled surface quality.

Manufacturing processes include:

• CNC milling and turning

• Precision surface grinding

• Fine finishing for critical fitting areas

• EDM processing (if required by design)

• Dimensional inspection and verification
