Heya Precision: Custom-Made Injection Mold Guide Pins & Bushings – Per Client’s Precision Drawings, Anti-Rust (S136 Steel) For Stable Mold Alignment

Why Heya’s Custom Guide Pins & Bushings Stand Out

• Mismatch with client drawings leads to poor mold alignment (e.g., cavity-core offset), resulting in defective plastic parts (flash, uneven thickness);
• Ordinary steel materials rust easily in humid production environments (e.g., injection molding for bathroom appliances), shortening service life to 50,000 cycles or less;
• Insufficient precision causes excessive friction between pins and bushings, accelerating mold wear and forcing unplanned maintenance.

Core Customization Capabilities for Client-Drawn Guide Pins & Bushings

Technical Specs: Built for Stable Mold Alignment

Quality & Compliance for Global Molders

• Dual Certifications: ISO 9001 (general manufacturing) and IATF 16949 (automotive-grade) to meet strict quality requirements for automotive, electronic, and medical plastic molds.
• Material Traceability: Full documentation (S136 steel mill certificates, nitride coating test reports, dimensional inspection records) provided for every batch—critical for supply chain audits.
• Pre-Production Validation: We test guide pins & bushings in a mock mold setup (simulating 10,000 injection cycles) to verify alignment stability and wear resistance before delivery—catching issues like excessive friction early.

Who Benefits from Our Client-Drawn Guide Pins & Bushings

• Automotive Mold Manufacturers: For high-precision molds (e.g., engine sensor housings, interior trim molds) where stable alignment ensures compliance with IATF 16949 standards.
• Electronic Plastic Molders: For delicate molds (e.g., smartphone casing molds, IoT device molds) where even 0.005mm misalignment causes part defects.
• High-Humidity Production Facilities: For molders making bathroom appliances, water filters, or outdoor plastic parts—anti-rust S136 steel eliminates rust-related downtime.

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.
