Heya Precision: Custom-Made Injection Mold Guide Pins & Bushings – Per Client’s Precision Drawings, Anti-Rust (S136 Steel) For Stable Mold Alignment
Crafted exclusively for injection mold manufacturers (automotive, electronics, home appliance sectors), our custom guide pins & bushings are precision-machined to 1:1 match your 2D/3D precision drawings (CAD, STEP, DXF formats). Built with anti-rust S136 steel, they ensure long-term stable mold alignment—critical for preventing cavity-core misalignment, reducing mold wear, and ensuring consistent plastic part quality in high-volume production.
Why Heya’s Custom Guide Pins & Bushings Stand Out
Mold alignment relies on guide pins & bushings, but off-the-shelf or poorly customized options cause 3 major pain points for manufacturers:
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.
Heya solves these by engineering guide pins & bushings exactly to your precision drawings and using premium anti-rust S136 steel—delivering reliable alignment and long-lasting performance even in harsh production conditions.
Core Customization Capabilities for Client-Drawn Guide Pins & Bushings
We tailor every detail to your mold design and production environment, with flexibility to adapt to complex mold structures:
Custom tweaks to boost alignment stability—e.g., oil grooves reduce friction by 40%, cutting mold wear
Technical Specs: Built for Stable Mold Alignment
Our guide pins & bushings are engineered to protect your molds and improve production consistency, with specs that directly address alignment and durability needs:
Specification
Heya Standard for Custom Guide Pins & Bushings
Impact on Your Mold Production
Dimensional Tolerance
±0.002mm (pin diameter/bushing inner diameter)
Perfect clearance between pins and bushings (0.003mm–0.005mm) to prevent misalignment—no flash or uneven plastic parts
Anti-Rust Performance
Passes 500-hour salt spray test (S136 steel); 1,000-hour test (nitride-coated S136)
No rust even in humid environments (e.g., bathroom appliance molding)—avoids unplanned mold disassembly for rust removal
Reduces guide pin/bushing replacement frequency—cuts maintenance costs by 60% vs. ordinary steel
Lead Time
10–14 days (prototype); 18–22 days (mass-production)
Faster than industry average (25+ days) to minimize mold downtime during maintenance or new mold builds
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.
