Product Description
The Lifting Knife Cutting Machine is a high-efficiency cutting system designed for plastic extrusion production lines requiring fast and continuous cutting operations. It uses a vertical lifting blade mechanism that moves up and down in synchronization with the extrusion line, enabling precise cutting without stopping production.
This cutting system is widely used for small to medium diameter plastic pipes and profiles, especially in high-speed production environments where efficiency and consistency are critical.
Compared with traditional fixed cutters, the lifting knife system offers higher speed, reduced maintenance, and improved production continuity.
