Medical Ejector Pin Description
Definition:
A medical ejector pin is a precision-machined, high-strength metal pin used in injection molds to eject or push out molded plastic parts once they have cooled and solidified.
Key Characteristics:
Material: Typically made from hardened tool steels such as H13 or SKD61, which are resistant to wear, corrosion, and high temperatures. For medical applications, stainless steel or coated pins (e.g., TiN-coated) may be used to meet cleanliness and corrosion resistance standards.
Surface Finish: Highly polished or coated to meet cleanroom or sterility requirements for medical devices.
Tolerance: Manufactured to tight tolerances to ensure consistent part ejection and minimal wear on the mold.
Sterility and Cleanroom Compatibility: Designed to be used in molds for medical and pharmaceutical parts, so must comply with FDA or ISO 13485 standards.
Function: After the plastic is injected into the mold and cooled, ejector pins push the molded part out of the mold cavity cleanly, preventing deformation or damage.
Applications:
Used in the production of:
Syringes
IV components
Surgical instruments
Catheters
Inhalers
Diagnostic device casings
