Single-piece Ejector Pin Sleeve

Main functions and applications
Guidance and positioning:
The sleeve is used in conjunction with the ejector pin to ensure that the ejector pin, guide pin or inclined pin maintains linear motion during mold closing and demolding, reducing eccentric wear and increasing mold life.

Protection and wear resistance:
Made of high-hardness materials (such as SKD11, tungsten steel), reducing direct friction between the ejector pin and the template and reducing maintenance costs.

Simplified structure:
The "single-section" design refers to an integrated sleeve (non-segmented assembly), which is easy to install and has high stability, suitable for high-speed stamping or precision injection molding scenarios.

Typical scenarios
Injection mold: The ejector sleeve ensures smooth return of the ejection mechanism.

Stamping mold: Guide the punch or guide pin to ensure blanking accuracy.

Automation equipment: Guide components for the robot pick-up mechanism.

Advantages
The single-section structure has good rigidity and strict tolerance control (usually ±0.005mm), which is suitable for high-precision and large-scale production needs and is one of the key components for efficient operation of the mold.
