What Are Ejector Components?
Ejector components are precision-molded parts installed in the ejection system of injection molds. When the mold opens after each molding cycle, the ejection system activates—these components move forward, contact the molded part, and release it from the core surface.
This covers both ejector pins and other ejection-assist components such as sleeves and air valves.
Ejector Pins for Injection Molds
Explore the full range of ejector pins for injection molding—from general-purpose straight pins to specialized SKD61, nitrided, shouldered, stepped, blade, and square designs.
Complete guide to ejector pin types, materials, and selection for injection mold ejection systems.
SKD61 hot-work tool steel pins balance toughness, thermal stability, and wear resistance.
Surface-hardened pins for high-wear and high-cycle molding conditions.
Shouldered design for precise mounting, positioning, and stroke control.
Stepped diameters combining a small ejection tip with a stronger support shaft.
Other Ejector Components
Beyond standard ejector pins, HTX also supplies specialized ejector components for specific mold release and part ejection requirements.
Hollow ejector components for cylindrical bosses, cores, and annular ejection where even, balanced force is required.
Air-assisted mold components that release vacuum during ejection, helping thin-wall and deep-cavity parts separate cleanly.

Custom Ejector Components
Standard ejector components may not fit every mold design. HTX provides drawing-based customization for ejector pins, sleeves, and other precision ejection components according to required dimensions, geometry, tolerance, and material specifications.
Which Ejector Component Fits Your Mold?
| Your Mold Requirement | Component to Consider |
| General cylindrical ejection | Straight Ejector Pin |
| Need shoulder positioning | Shoulder Ejector Pin |
| Different diameters along the pin | Step Ejector Pin |
| Narrow or elongated ejection area | Blade Ejector Pin |
| Non-round ejection profile | Square Ejector Pin |
| Annular ejection around a core | Ejector Sleeve |
| Air-assisted release | Air Poppet Valve |
| Higher surface wear resistance | Nitrided Ejector Pin |
| Need a specific tool steel grade | SKD61 Ejector Pin |
