Ejector Sleeves: Precision Components for Tooling, Moulding & Die Casting
Ejector Solutions manufactures high-precision Ejector Sleeves designed for plastic injection moulds, high-pressure die casting (HPDC) dies, and complex precision tooling setups. Built to work seamlessly with ejector pins and core pins, our ejector sleeves allow for uniform, 360-degree force distribution during component ejection—preventing part distortion, sink marks, and stress fractures on delicate cylindrical boss features.
Crafted from premium alloy steels (such as DIN 1.2344 / AISI H13 and SKD61) and processed through advanced vacuum hardening and precision nitriding, our sleeves deliver high concentricity, exceptional surface hardness, and minimal friction under demanding operational thermal cycles.
Key Product Range & Features
- Standard Ejector Sleeves: Precision-ground inside and outside diameters (ID/OD) for perfect coaxial alignment and zero-play fit with core pins.
- Precision Sleeve Components: Nitrided or hardened options offering high surface hardness (up to 60–62 HRC / 900+ HV nitrided) to eliminate galling, scoring, and thermal wear during long production runs.
- Custom Ejector Sleeves: Tailored to specific engineering drawings—including custom step diameters, specialized wall thicknesses, counterbores, and extended lengths for deep-cavity tooling.
- Uniform Ejection Force: Provides equal radial force across circular rims, rib features, and central bosses, ensuring clean component release without flash formation.
- High Thermal Resistance: Engineered to endure severe thermal shock in hot-runner systems and aluminum/zinc die casting without dimensional drift or inner bore distortion.
