MD 3020 – Chipless Four Head Welding Machine

The MD 3020 is a high-performance chipless four-head welding machine designed for the production of PVC window and door frames. Built on a robust mechanical structure, it delivers deburring-free welding of both white and colored profiles at high speed and with exceptional quality. Its compact footprint, intuitive Windows-based control interface, and automatic lubrication system make it an efficient and reliable solution for modern PVC fabrication workshops.
