Straight Punching Ejector Pin For Plastic Injection Molding 0.5x80mm HSS W6542 With Round Tip And Nitrided Surface High Hardness HRC63-65 Durable Alloy Steel For Precision Fit And Rugged Wear Resistant Tooling
✔️ Precision HSS ejector pin with nitrided surface for rugged use
This straight ejector pin is designed for plastic injection molding, delivering reliable part ejection and mold protection in high-temperature, high-wear environments. It is typically used inside mold cavities and ejector systems to push finished parts out after molding, reducing cycle times and preserving mold integrity.
✅ Hardened alloy steel construction resists bending under high stress
✅ Nitrided surface reduces wear and prevents scratches on molds
✅ High hardness HRC63-65 for long service life
✅ Straight shaft and uniform round head ensure precise alignment
✅ Ideal for mold maintenance, part ejection, and rugged manufacturing
💡 What is an ejector pin used for in plastic injection molding?
In short, it pushes finished parts out of the mold after curing, helping protect the mold and surface finish. Handy points:
- Ejects molded parts cleanly without damaging mold cavities
- Maintains precise alignment and repeatable ejection force
- Made from hardened alloy steel with nitrided surface for wear and rust resistance
- Ideal for high-volume production and demanding molding environments
