Straight Punching Ejector Pin 65Mn Round Tip For Plastic Injection Molding Durable Hardened Steel Component Pack Of 10 4x200mm Precision Workpiece Protection And Smooth Nitrided Surface
✔️ Pack of 10, 4x200mm, hardened steel, nitrided surface
These straight punching ejector pins are precision-machined components designed for plastic injection molding. They are installed in mold cores to push finished parts free after curing, helping maintain mold surface quality and high production throughput. The nitrided surface reduces scratches and wear on delicate molds and finished parts.
✅ Material and hardness: Hardened alloy steel with 65Mn tip; 4 mm diameter, available with bearing steel variants (HRC58-60) or 65Mn (HRC50-52). ✅ Surface: Precision-smooth nitrided finish to minimize mold wear and scratches. ✅ Precision: Straight shaft and uniform round head for accurate alignment. ✅ Size options: Lengths from 60 to 450 mm in 12 sizes; diameter 4 mm; pack of 10. ✅ Application: Ideal for mold maintenance, part ejection, and heavy-duty manufacturing.
