This injection mould is purpose-built for high-precision production of automotive audio speaker housings and grilles. It supports PP, ABS, PC/ABS, and other automotive-grade thermoplastics. Finished parts feature a premium textured surface finish, with exact color matching to vehicle interior tones via RAL and PANTONE color standards. The mould adopts a modular cavity design, enabling flexible configuration from prototype validation to mass production.

Why This Mould
- Built to last. P20 steel core and cavity with S45C mould base, engineered for 300,000+ injection cycles without compromise.
- HASCO-standardized. Globally compatible standard components make maintenance and spare part replacement straightforward — no vendor lock-in.
- Cold runner efficiency. Designed specifically for PP material flow, reducing setup complexity and cycle time.
- Surface quality that sells. From mirror polish (SPI A1–A3) to textured leather grain, the finished parts match automotive interior standards with consistent color reproduction.
- Flexible cavity layout. Start with a single cavity for validation, scale to four cavities for volume production — the modular design adapts to your demand.
