Heya Precision: Custom Injection Mold Cavity Cores for Plastic Parts – Tailored to Client’s 2D/3D Drawings, High-Tolerance (±0.005mm) & Compatible with PC/ABS Resins
Designed for plastic part manufacturers (automotive, electronics, consumer goods) needing fully customized mold components, our cavity cores are 100% aligned with your 2D/3D drawings (CAD, STEP, IGES formats) to fit seamlessly into your existing injection mold systems. We prioritize precision and resin compatibility to eliminate production delays—critical for high-volume plastic parts like automotive sensor housings, electronic device casings, and consumer product enclosures.
Why Heya’s Custom Injection Mold Cavity Cores Stand Out
Plastic part manufacturers face 3 core pain points with off-the-shelf or poorly customized cavity cores:
Mismatch with client drawings leads to mold assembly issues and costly rework;
Insufficient tolerance causes inconsistent plastic part dimensions (e.g., loose fits in device casings);
Poor resin compatibility results in sticking, warping, or shortened mold life.
Heya solves these by engineering cavity cores exclusively for your drawings—combining 18+ years of precision machining experience with strict quality controls to meet even the most demanding plastic molding needs.
Core Customization Capabilities for Client-Drawn Cavity Cores
We tailor every detail to your drawings and production requirements, with flexibility to adapt to unique plastic part designs:
S136 steel (corrosion-resistant for humid environments), H13 steel (high-wear for high-volume runs)
Pre-hardened steel cuts heat-treatment time by 7 days; material certificates provided for traceability
Precision Control
±0.005mm dimensional tolerance, Ra ≤0.008μm surface finish
CNC machining with Zeiss CMM inspection (±0.0005mm accuracy) to ensure no part fit issues
PC/ABS Resin Compatibility
Optimized cavity geometry for PC (heat-resistant) & ABS (impact-resistant)
Cooling channel design tailored to PC/ABS shrinkage rates (PC: 0.5–0.7%, ABS: 0.3–0.5%) to prevent warping
Technical Specs: Built for Precision Plastic Molding
Our cavity cores meet the strict standards of high-volume injection molding, with specs that directly boost your production efficiency:

Faster than industry average (25+ days) to meet tight product launch timelines
Post-Production Inspection
Zeiss CMM testing + visual surface checks
100% defect-free rate before delivery; no unexpected mold failures
Quality & Compliance for Global Manufacturers
ISO 9001 Certified: Every cavity core undergoes rigorous inspection to meet international quality standards—critical for clients in automotive (IATF 16949-aligned) and electronics industries.
Material Traceability: Full documentation (mill certificates, heat-treatment records) provided for every steel batch, ensuring transparency for your supply chain audits.
Pre-Production Testing: We run 50–100 test injections with your target resin (PC/ABS) to verify cavity core performance—catching issues like resin sticking or uneven filling before mass production.
Who Benefits from Our Custom Cavity Cores
Automotive Plastic Part Manufacturers: For components like sensor housings, interior trims, and under-hood plastic parts (PC/ABS compatibility ideal for heat/humidity resistance).
Electronic Device Makers: For precision casings (e.g., smartphone chargers, IoT device enclosures) where ±0.005mm tolerance ensures component alignment.
Consumer Goods Injection Molders: For high-volume products (e.g., toy parts, home appliance enclosures) needing durable, cost-effective cavity cores tailored to unique drawings.
