Wear Resistant Steel Injection Mold Ejector Pins For High Volume Plastic Molding

Heya Precision: Per-Client-Drawing Custom Injection Mold Ejector Pins

Engineered exclusively for injection molders and plastic part manufacturers (automotive, consumer goods, electronics), our custom ejector pins are precision-machined to match your CAD/STEP files—ensuring seamless integration with your existing molds and reliable performance for high-volume plastic production. We focus on wear resistance and dimensional accuracy to eliminate common pain points like ejector pin failure or part damage during demolding.

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

High-volume plastic molding relies on ejector pins to safely release parts—but off-the-shelf pins often cause 3 critical issues:


  • Mismatch with mold designs (from poor drawing alignment) leads to stuck pins or uneven part ejection;
  • Low-wear materials break down after 50,000+ cycles, forcing unplanned downtime;
  • Inconsistent precision causes part scratches or deformation during demolding.


Heya solves these by building ejector pins 1:1 to your CAD/STEP files and using premium wear-resistant steel—ensuring they stand up to high-volume runs while protecting your plastic parts.

Core Customization Capabilities for Client-Drawn Ejector Pins

We tailor every ejector pin to your unique mold design and production needs, with flexibility to adapt to complex part geometries:


Customization DimensionKey OptionsHeya Advantage
Client Drawing Support3D (CAD/STEP/IGES) & 2D (DXF/PDF) files; custom lengths/diameters per designFree pre-production drawing review to fix alignment issues (e.g., pin-to-mold fit); 100% drawing accuracy guaranteed
Wear-Resistant MaterialH13 steel (for 300,000+ cycles), SKD61 steel (corrosion-resistant for humid molding), nitride-coated steel (extra wear protection)Materials selected for your production volume—e.g., H13 steel cuts pin replacement frequency by 60% vs. standard steel
Precision Machining±0.003mm dimensional tolerance; Ra ≤0.01μm surface finish (prevents part scratches)CNC turning + grinding with Zeiss CMM inspection to ensure pin straightness (≤0.002mm/m) for smooth ejection
High-Volume AdaptationsTapered tips (for delicate parts), stepped shafts (for mold alignment), lubrication grooves (reduces friction)Design tweaks to support 100,000+ monthly part runs—e.g., lubrication grooves cut pin wear by 25%

Technical Specs: Built for High-Volume Plastic Molding

Our ejector pins are engineered to minimize downtime and protect your parts, with specs that directly boost production efficiency:


SpecificationHeya Standard for Custom Ejector PinsImpact on Your Plastic Molding Process
Dimensional Tolerance±0.003mm (diameter/length)Perfect fit with your mold; no stuck pins or uneven ejection (reduces part damage by 90%)
Service Life≥300,000 cycles (H13 steel); ≥200,000 cycles (SKD61 steel)Sustains high-volume runs (e.g., 500,000+ plastic parts) without pin replacement
Lead Time8–12 days (prototype); 15–18 days (mass-production)Faster than industry average (20+ days) to avoid mold downtime during peak production
Demolding CompatibilityWorks with PC/ABS/PP/TPU resins; safe for thin-walled parts (≥0.5mm)No part warping or scratches—ideal for delicate components like electronic casings or automotive interior trims

Quality & Compliance for Global Molders

  • ISO 9001 Certified: Every ejector pin undergoes rigorous testing (hardness: 58–62 HRC for H13 steel; straightness checks) to meet international quality standards.
  • Material Traceability: Full documentation (mill certificates, heat-treatment records, nitride coating reports) provided for every batch—critical for automotive (IATF 16949) and medical plastic clients.
  • Pre-Production Validation: We test ejector pins in a mock mold setup (using your target resin) to verify ejection force and wear resistance before delivery—catching issues like excessive friction early.

Who Benefits from Our Client-Drawn Ejector Pins

  • Automotive Plastic Part Molders: For high-volume components (e.g., bumper clips, sensor housings) where wear-resistant pins avoid production line shutdowns.
  • Consumer Electronics Injection Factories: For delicate parts (e.g., smartphone battery casings, IoT device enclosures) where precision prevents scratches or deformation.
  • Large-Scale Consumer Goods Manufacturers: For daily-use plastic products (e.g., toy parts, home appliance knobs) needing reliable ejector pins for 24/7 production runs.
