[Case Studies by Application] Ultra-Hard Ejector Pins

We have various grinding machines! We respond with grinding methods suitable for the shape and material.

This is a case of an ejection pin designed to eject resin-molded products from a mold, made of ultra-hard alloy to withstand wear even after being used repeatedly over tens of thousands of times. The outer diameter dimension tolerance is specified as ±2μm, but due to the large length relative to the diameter, such grinding processes can lead to the item escaping and make it difficult to achieve concentricity. There are also stringent requirements for geometric tolerances such as straightness tolerance. Our company possesses various grinding machines and responds with grinding methods suited to the shape and material.
