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).
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.”
We tailor every locating pin to your mold’s unique alignment needs, with flexibility to adapt to complex mold structures and resin types:

Our locating pins are engineered to meet the strictest alignment standards, with specs that directly reduce defects and unplanned downtime:
- 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.

- 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.
