Precision Plastic Mold Parts Ejector Pins & Sleeves


Precision Plastic Mold Parts

Precision Plastic Mold Parts are used in the Medical and Electronics Industries. They can be called mold core pins, or ejector pins and sleeves.

The Precision Plastic Mold Parts are machined by Round and Cylindrical Grinding + Precision Wire EDM Processing + Precision Surface Grinding Technology.

The Plastic Mold Parts are used in the injection mold. And the custom-made parts usually are micro-precision parts with high-accuracy requirements.

These plastic mold precision parts include core and cavity sets, ejector pins and sleeves, guide pins and bushings, etc.

Most of these parts are special parts made according to customers’ drawings.

The materials used are hard metals like stainless steel, HSS, or even carbide.

Welcome to send your specific drawings/part no. with your requirements to us for quotations.
