Core Pins

High-Precision Cavity Profile & Thermal Stability

• Flawless Part Detail Definition: Custom machined to serve as the critical male insert that profiles internal plastic part features, demanding high dimensional accuracy and geometric control.
• Premium Hot-Work Alloys: Fabricated from elite hot-work tool steels like SKD61, SKH51, or DAC, retaining structural hardness and resisting thermal checking under repetitive molten plastic contact.
• High Surface Finish Execution: Micro-polished finish profiles down to a near-mirror shine eliminate mechanical draft resistance, ensuring pristine molded parts without scratch defects.

Customization & Non-Standard OEM Expertise

• Tailored to Your Drawings: We offer comprehensive OEM/ODM manufacturing flexibility, delivering high-precision core pins processed exactly to your provided 2D blueprints (PDF/DXF) and 3D CAD models (STEP/IGS).
• Specialized Intricate Geometries: We excel at processing complex non-circular tips, custom angled cooling vents, deep engraving indicators, specific internal cooling holes, and tight tapers that catalog stocks do not support.
• Rapid Prototyping Response: Efficient machining setups mean quick tooling changes and faster dispatch dates, keeping your test molds and assembly deadlines perfectly synchronized.

Technical Specifications

• Processing Capabilities: Multi-Axis Cylindrical Grinding, Precision Wire-Cut EDM, Profile Surface Polishing.
• Achievable Tolerances: Forming profile sizing matched up to ±0.005mm; concentricity values checked within 0.008mm.
• Surface Hardness Ranges: Base core hard-tempered to HRC 48-52; surface coatings available up to HV 1000 for corrosive plastics.

We are committed to helping industrial buyers, localized workshop managers, and emerging product designers grow by offering flexible purchasing with absolutely no minimum order quantity (MOQ) pressures. Whether you require a single standalone replacement core pin or a complete set of multi-cavity forming inserts, we deliver premium results with minimal stock burden.
