Ejector Pins

High-Hardness & Wear-Resistant Engineering

• Premium Tool Steel Base: Manufactured from superior-grade SKD61, SKH51, or WS hot-work tool steels to ensure optimal mechanical stability and resistance to thermal fatigue during high-volume injection cycles.
• Advanced Surface Treatment: Available in through-hardened, nitrided, or specialized DLC (Diamond-Like Carbon) coated variations to significantly lower the friction coefficient and prevent surface galling.
• Flawless Precision Sizing: Micro-ground finishes achieve high-tolerance concentricity and straightness, minimizing flashing at the part gate and ensuring clean component separation.

Customization & Non-Standard OEM Expertise

• Tailored to Your Drawings: We offer comprehensive OEM/ODM manufacturing flexibility, delivering high-precision ejector pins machined exactly to your provided 2D blueprints (PDF/DXF) and 3D CAD models (STEP/IGS).
• Specialized Non-Standard Geometries: We excel at processing customized stepped diameters, irregular shoulder lengths, flat ejector shapes, and tailored point profiles that off-the-shelf mass catalogs cannot supply.
• Rapid Turnaround & Secure Shipping: Fully optimized toolpaths allow for swift technical execution, ensuring minimal lead times and highly responsive shipping schedules to eliminate factory toolroom downtime.

Technical Specifications

• Hinge & Pin Mechanism Configuration: Straight Type, Stepped Shoulder Type, Flat/Blade Configurations.
• Achievable Tolerances: Shaft diameter up to -0.005mm to -0.01mm; head thickness within ±0.02mm.
• Surface Hardness: Core hardness of HRC 40-45 with a nitrided surface hardness exceeding HV 900.

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 replacement pin set or a low-volume custom batch for a new mold platform, we deliver premium results with minimal stock burden.
