DIN ISO 8405 Ejector sleeve with cylindrical head DIN 16756
Our ejector sleeves are high-precision mold components manufactured to strict international standards DIN 16756 and DIN ISO 8405. Designed to be used with matching sleeve ejector pins, they provide an optimal ejection solution for deep cavities, thin ribs, or other challenging plastic parts where standard ejector pins are not suitable. They ensure a stable, reliable, and efficient ejection process in injection molding.
Key Features & Benefits
International Standard, Perfect Interchangeability
Strict adherence to DIN 16756 and DIN ISO 8405 guarantees dimensional accuracy and global interchangeability. This simplifies mold design, maintenance, and component sourcing, significantly reducing inventory costs.
Superior Wear Resistance & Rigidity
Made from high-quality alloy steel and subjected to specialized heat treatment, our sleeves possess high hardness and exceptional wear resistance. They effectively withstand wear and deformation even under long-term, high-frequency cycling, dramatically extending mold service life.
Optimized Ejection Performance
Ejector sleeves provide a larger contact area than standard ejector pins, effectively preventing damage such as whitening or piercing on deep-core or delicate plastic parts. This is crucial for ensuring the quality of complex molded components.
High Precision & Stability
The inner and outer walls are precision-ground to achieve excellent concentricity and a superior surface finish. This ensures smooth interaction with the sleeve ejector pin, minimizes friction, prevents seizing, and guarantees a consistently smooth ejection action.
