This CNC four‑point welding machine is specially designed for UPVC plastic‑steel door‑and‑window processing. It comes‑with double‑layer welding stations, and the welding‑height for the single‑layer station reaches 130 mm.
Two complete window frames can be welded at the same time on its dual decks, doubling production capacity compared with the single‑layer four‑corner welder, which suits mass‑production workshops.
