Ejector Housing

The ejector housing is a critical component of ejection systems used in manufacturing processes such as injection molding, die casting, and stamping. It serves as the protective casing that contains the ejector pins, plates, and associated mechanisms, ensuring proper alignment, guiding the ejection stroke, and preventing damage to the internal components from external forces or contaminants. The housing remains stationary during the molding or casting process. After part formation, the internal ejector mechanism (pins or plate) is actuated, pushing the finished part out of the mold or die. The housing guides this linear motion, absorbs reaction forces, and maintains the precise alignment of all internal ejector components throughout the cycle. Materials on file include tool steel and aluminum alloy. Reference parameters include operating pressure 1.0–1.6 MPa, operating temperature -20–80 °C, material grade GG25 (DIN 1691), surface treatment zinc-plated (ISO 2081), tensile strength 250–350 MPa (ISO 185), hardness 170–230 HB (ISO 6506-1), dimensional tolerance ±0.1 mm (ISO 2768-m), weight 15–60 kg, surface roughness Ra 3.2 μm (ISO 1302), pressure rating PN16 (ISO 7268), leakage rate ≤0.1 mL/min, and ingress protection IP54 (IEC 60529). These values are directory reference ranges and must be confirmed for the actual model and application. Standards listed are procurement references, not proof of certification or compliance. Verify model-specific values and standards with the legal manufacturer or supplier.

The housing remains stationary during the molding or casting process. After part formation, the internal ejector mechanism (pins or plate) is actuated, pushing the finished part out of the mold or die. The housing guides this linear motion, absorbs reaction forces, and maintains the precise alignment of all internal ejector components throughout the cycle. It also protects the mechanism from external contaminants and mechanical damage, ensuring consistent ejection performance and prolonging service life.
