Relay plastic injection mould

Detailed Description

This mould adopts a hot runner system with a 32‑cavity high‑density layout, designed for high‑volume, high‑efficiency production of relay components. The hot runner eliminates runner waste, reduces material cost, and ensures balanced filling across all 32 cavities, resulting in consistent part dimensions. Suitable for mass production of magnetic latching relays, automotive relays, power relays, and other relay types.

Key features:

• 32‑cavity high output: produces 32 relay components per shot, significantly increasing productivity

• Hot runner system: valve gate nozzles for small gate marks and fully automatic operation

• Precision balancing: mold flow analysis optimizes runner layout, ensuring filling time variation ≤5% across 32 cavities

• Long‑life material: cavities/cores made of premium tool steel (S136, H13, etc.), hardened to HRC50‑52

• Tight tolerances: critical dimensions (hinge holes, snap features) ±0.01mm

• Quick color/material change: hot runner can be configured with purge‑ready design for easy switching

Typical applications:

• Magnetic latching relay housing & base

• Automotive relay cover and bobbin

• Power relay case

• Signal relay insulating parts

• Relay contact carrier
