Family-specific questions
Which molds suit square ejector pins?
Molds needing side ejection or high precision and repeatability.
Do you support metric square ejector pins?
Yes—metric series and both metric and imperial sizes on request.
How to extend square pin service life?
Nitriding and similar treatments improve wear resistance; precision grinding reduces ejection friction and extends life.
