Four Head Welding Machine PVC Window Frame Welding Equipment
Four Head Welding Machine - PVC Window Angle Frame Welding Equipment is a high-precision professional device for UPVC, PVC and plastic steel door and window frame processing. Four Head Welding Machine PVC Window Frame Welding Equipment supports dual working modes of independent single-head operation and four-head linkage synchronous work, realizing one-step forming for standard rectangular frames and various special-shaped window frames to meet diverse production needs. Equipped with advanced seamless welding technology, accurate pneumatic clamping and stable PLC intelligent control system, the machine fits ordinary PVC profiles, co-extruded colored profiles and film-coated profiles perfectly. With flexible batch customization, pre-job machine debugging service and stable operational performance, it lowers production thresholds and brings reliable long-term returns for profile processing manufacturers.
Produced by Lebulang Machine, a China-based manufacturer with nearly 30 years of factory experience in window and door processing equipment, this four-head welding machine is built for joining PVC, UPVC, and plastic-steel profiles. The machine is supplied on a factory-direct basis, supports OEM and ODM customization, and holds CE and ISO certification.
The four welding heads operate independently or in combination, covering angles from 30° to 180°. A constant-temperature heating plate and constant-pressure pressing cycle deliver uniform weld strength and flatness across each joint. Integrated seam-cleaning cutters built into the clamps trim the weld bead during the same cycle, so a separate finishing step is unnecessary. The clamping system is designed to handle ordinary white profiles, co-extruded colored profiles, and film-coated profiles while minimizing surface damage such as film tearing or blistering. Weld seam thickness is adjustable from 0.2 mm to 2 mm.
Welding parameters are stored and recalled via a PLC interface. Linear guide rails carry the moving components to maintain positioning accuracy across frame sizes from 400 mm to 4500 mm. Maximum profile section capacity is 120 × 120 mm. The machine operates on a 380V three-phase supply, draws 4.5 kW, and requires 0.5–0.8 MPa air pressure. Its overall dimensions are 5300 × 900 × 1700 mm. Remote installation guidance is provided at no additional charge.
