Precision Flat Ejector Pins & Return Pins – HASCO Standard

The high precision flat ejector pin, designed to HASCO standards, is a crucial component in plastic injection molds for accurate ejection of molded parts.
Manufactured with precision machining, these ejector blades and return pins are designed for stable, repeatable ejection and long-lasting performance in multi-cavity, high-cycle molding applications for packaging, medical, and industrial components.

• Manufactured to HASCO standards or built-to-print specifications

• Flat ejector pin design for high precision and accurate ejection

• Return pins and ejector blades made from durable, wear-resistant materials

• Ensures smooth and efficient part ejection in multi-cavity molds

• Suitable for high-cycle and continuous molding operations

• Precision CNC machining for tight tolerances and reliable functionality

• Corrosion-resistant materials for long-term durability

These high-precision ejector pins and blades are widely used in injection molds for:

• Bottle caps and closures

• Packaging containers and thin-wall plastic parts

• Medical disposables and syringe-related components

• Injection molds requiring precise part ejection and smooth cycle operation

Typical customers include packaging manufacturers, cap and closure producers, medical consumable factories, and OEM injection mold manufacturers.

The flat ejector pin and return pin system are installed within the mold cavity to ensure precise part ejection during the mold opening process.
The return pins serve to reset the ejector pin after each cycle, ensuring consistent and repeatable ejection. The design minimizes friction and wear, reducing the risk of failure in high-cycle operations.
Key considerations for the design include tolerance control, surface finish, and material selection to ensure the pins can withstand the high demands of multi-cavity mold systems.

All ejector pins, return pins, and ejector blades are manufactured in-house using precision CNC machining processes.

Manufacturing capabilities include:

• CNC turning and milling for precision components

• High-quality steel and other durable materials for wear resistance

• Precision grinding for smooth pin movement and fit

• Tight tolerance control to ensure proper function in multi-cavity molds

In-house inspection equipment is used throughout production to ensure dimensional accuracy and consistent performance.
