Set of four-ring punch with connector

The spring‑loaded, internally supported variable‑diameter high‑seal ring punch is a newly launched patented product of our company.

Details

The spring‑loaded, internally supported variable‑diameter high‑seal ring punch is a newly launched patented product of our company. Its structural design draws on the principles of piston rings, enabling the punch to achieve a highly sealed state under high‑pressure injection.

In the overall punch assembly, the ring seat and the connecting sleeve serve to secure the components; a Grade 14.9 bolt is used to fasten these two parts, ensuring that all rings remain tightly secured and do not come loose during the injection‑molding process.
