Precision Injection Mold Locating Pins For Resin Proof Materials
Heya Precision: Custom Injection Mold Locating Pins For Precision Molding
Crafted exclusively for injection mold manufacturers (automotive, electronics, medical devices) where mold alignment is non-negotiable, our custom locating pins are precision-machined to 1:1 match your exact 2D/3D drawings (CAD, STEP, DXF). With ultra-tight ±0.003mm tolerance and resin-proof materials, they eliminate cavity-core misalignment, resist corrosion from plastic resins (PC/ABS/PP) and cleaning agents, and ensure consistent precision for high-volume molding of tight-tolerance parts (e.g., electronic connectors, medical components).
Why Heya's Custom Client-Drawn Locating Pins Stand Out
Locating pins are the "alignment backbone" of injection molds--but off-the-shelf or poorly customized options create 3 critical pain points for precision-focused manufacturers:
- Mismatch with client drawings leads to 0.01mm+ cavity-core offset, causing defective parts (flash, uneven wall thickness) or mold damage;
- Insufficient tolerance (e.g., ±0.01mm) fails to meet tight standards for industries like medical (FDA) or automotive (IATF 16949);
- Ordinary steel materials degrade from resin residues or chemical cleaners, shortening service life to 100,000 cycles or less.
Heya solves these by engineering locating pins exactly to your drawings and using resin-proof, high-hardness materials--turning "alignment risk" into "production reliability."
Core Customization Capabilities for Client-Drawn Locating Pins
We tailor every locating pin to your mold's unique alignment needs, with flexibility to adapt to complex mold structures and resin types:
| Customization Dimension |
Key Options |
Heya Advantage |
| Client Drawing Support |
2D (DXF/PDF) & 3D (CAD/STEP/IGES) files; custom lengths (8mm-300mm) & diameters (3mm-40mm) |
Free pre-production drawing review to optimize pin placement (e.g., avoiding resin flow paths); 100% drawing accuracy guaranteed--no post-delivery modifications needed |
| Resin-Proof Materials |
S136 stainless steel (resists PC/ABS resin residues), nitride-coated H13 steel (extra corrosion resistance for chemical cleaners), ceramic-reinforced steel (for abrasive resins like glass-filled PP) |
Materials tested to withstand 500+ cycles of resin exposure without staining or corrosion--extends pin life by 3x vs. ordinary carbon steel |
| Ultra-Precision Machining |
±0.003mm dimensional tolerance; Ra ≤0.005μm surface finish (reduces friction); concentricity ≤0.001mm |
CNC grinding + lapping with Zeiss CMM inspection (±0.0005mm accuracy) to ensure pin straightness--critical for molds requiring 0.005mm max cavity-core offset |
| Alignment Enhancements |
Tapered tips (for easy mold assembly), flange bases (for stable installation), threaded shafts (for quick replacement) |
Custom tweaks to boost usability--e.g., flange bases eliminate pin "wobble" during injection, cutting misalignment-related defects by 95% |
Technical Specs: Built for Precision Molding Alignment
Our locating pins are engineered to meet the strictest alignment standards, with specs that directly reduce defects and unplanned downtime:

No pin replacement due to resin corrosion--cuts maintenance costs by 60% vs. standard steel pins |
| Service Life |
≥400,000 cycles (S136 steel); ≥600,000 cycles (nitride-coated H13) |
Sustains high-volume runs (e.g., 300,000+ electronic connectors) without alignment drift |
| Lead Time |
9-13 days (prototype); 16-20 days (mass-production) |
Faster than industry average (25+ days) to minimize mold downtime during new builds or maintenance |
Quality & Compliance for Global Molders
- Dual Certifications: ISO 9001 (general manufacturing) and IATF 16949 (automotive-grade) to meet strict standards for precision industries. Medical clients also receive FDA-compliant material documentation for resin-proof pins.
- Material Traceability: Full batch records (mill certificates, nitride coating test reports, dimensional inspection data) provided for every order--critical for supply chain audits (e.g., automotive OEMs, medical device regulators).
- Pre-Production Validation: We test locating pins in a mock mold setup (simulating 10,000 injection cycles) to verify alignment stability, resin resistance, and wear performance before delivery--catching issues like micro-bending early.
Who Benefits from Our Client-Drawn Locating Pins
- Automotive Mold Manufacturers: For high-precision molds (e.g., engine sensor housings, transmission plastic parts) where IATF 16949 requires ≤0.005mm alignment tolerance.
- Electronic Component Molders: For tiny parts (e.g., USB-C connector casings, smartphone camera modules) where even 0.003mm misalignment causes functional defects.
- Medical Device Producers: For molds using corrosive resins (e.g., PEEK for surgical tools) or requiring frequent cleaning--resin-proof S136 pins meet FDA standards and avoid contamination risks.
