Low‑voltage electrical plastic injection mould

Detailed Description

This mould adopts a cold runner + 2‑plate design, optimized for flame‑retardant materials (PA66+GF, PBT, MC nylon) commonly used in low‑voltage electrical products. The 1×8 cavity layout balances productivity and molding stability, suitable for medium‑volume production.

Key features:

• Balanced runner system via mold flow analysis to ensure uniform filling and consistent part dimensions across all 8 cavities

• Precision machining: critical tolerances ±0.01mm for assembly requirements

• Ejection system: ejector pins + stripper plate to prevent distortion of thin‑wall parts

• Wear‑resistant cavities: S136 or H13 steel hardened to HRC48‑52 for glass‑filled materials

• Hot runner upgrade ready: can be converted to hot runner on the same mould base if volume increases

Typical applications:

• Miniature circuit breaker (MCB) housing (1P/2P/3P)

• Wall switch base

• Socket insulating base

• Residual current device (RCD) casing
