Product Description
An ejector pin is a mechanical component used in injection molding, die casting, and other types of mold-based manufacturing to push the finished part out of the mold once it has cooled and solidified.
Ejector Pin Description:
Function: Ejector pins push molded parts out of the mold cavity during the ejection phase of the molding cycle.
Material: Usually made of hardened steel to withstand wear, heat, and mechanical stress.
Placement: Mounted inside the mold base, typically on the ejector plate, which moves the pins forward once the mold opens.
Shape and Size: Cylindrical, but can vary in diameter and length depending on part geometry. Some have flat, domed, or custom-shaped ends to avoid damaging the part.
Types:
Straight ejector pins
Shoulder (headed) ejector pins
Blade (flat) ejector pins
Sleeve ejector pins
Key Considerations:
Placement must avoid marks on visible areas of the part.
Incorrect use can lead to part damage, sticking, or poor cycle time.
