Heya Precision: Custom Injection Mold Locating Pins For Precision Molding

Why Heya’s Custom Client-Drawn Locating Pins Stand Out

• 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.

Core Customization Capabilities for Client-Drawn Locating Pins

Technical Specs: Built for Precision Molding Alignment

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.

Heya Precision: Factory Overview & Production Excellence

Factory Basics: Location & Scale

• Strategic Location: Based in Dongguan, China’s core precision manufacturing hub—enabling efficient access to raw material suppliers, logistics networks, and global shipping ports (Shenzhen/Hong Kong), ensuring timely delivery for international clients.
• Optimized Space: Over 1000㎡ of dedicated production area, divided into functional zones (precision machining, electroforming, plastic molding, surface treatment, and quality inspection) to streamline workflows and minimize cross-contamination risks.
• Compliant Environment: Adheres to industrial safety and environmental standards, with well-ventilated workspaces, anti-static flooring in precision zones, and organized storage for mold components—reflecting our commitment to orderly, professional production.

Production Capabilities: Equipment & Processes

• Precision Machining Zone: Hosts high-speed CNC engraving machines (for intricate mold details) and multi-axis CNC machining centers—capable of handling complex mold geometries with dimensional tolerance as tight as ±0.005mm, critical for electroformed mold cores.
• Surface Treatment Zone: Features in-house mold texturing (pattern etching) and brushing finish equipment—eliminating reliance on third-party vendors to reduce lead times. We also offer outsourced texturing/brushing services for external mold manufacturers, showcasing our flexible capabilities.
• Plastic Molding Zone: Includes injection molding machines tailored for small-to-medium volume plastic parts, compatible with diverse resins (PC, PMMA, ABS) commonly used in automotive, electronics, and consumer goods industries.

Team & Quality Control

• Skilled Workforce: A 30+ team of experienced professionals, including 5+ senior mold engineers (with 10+ years in precision machining), 12+ certified technicians, and dedicated quality inspectors—ensuring every stage (from raw material intake to final mold testing) meets Heya Precision’s standards.
• End-to-End Quality Checks: Embeds strict inspection checkpoints:
  • Raw material verification (mold steel, resins) with supplier certificates;
  • In-process testing (CMM measurements for machining accuracy, surface roughness tests for texturing);
  • Final validation (mold trial runs, dimensional sampling) before shipment.

Support for OEM/ODM

• Flexible Production Lines: Accommodate small-batch prototype orders (e.g., 1–10 mold cores) and medium-volume production (100–5,000 plastic parts) without compromising precision.
• Collaborative Workflow: Dedicates project managers to OEM/ODM clients, ensuring clear communication between your team and our factory—from design confirmation (DFM analysis) to production scheduling and post-delivery support.
