Description

WM 750 Four Head Welding Machine

Standard Features

  • Welds four corners of PVC profiles simultaneously at 90 °with high sensitivity and strength
  • Machine axes are moved by Servo motor system (3 Servo motor controlled axes)
  • Specially developed parallel welding technology that improves welding quality and strength
  • Internally engineered design for automatic selection of 0.2 and 2 mm welding range
  • Beckhoff brand, high performance industrial PC operated by Windows XP Embedded. Fanless motherboard system works between 0°C – 55°C, and it comes with a 15” touch screen display
  • Data transfer via ethernet network connection, wireless network connection or USB interface
  • Welding parameters are defined by the user for every individual profile(up to 10,000 profiles)
  • Welding temperature, melting and welding times can be adjusted individually for each profile type.
  • All machine axes are moved by hardened steel ball screw which provides accuracy and durability.
  • Depending on the torque values of the servo motors, melting the lengths up to 2 mm and bringing them to the desired size
  • PC controlled (PID) heat control system to obtain strong welding results in compliance with standards.
  • Summer / winter working mode is automatically selected,so the temperature adjustment is done easily
  • Horizontally placed strong mechanical heating plates distribute heat homogeneously without being affected from difficult working conditions.
  • Easy and fast change for teflons by specially designed roll up teflon system.
  • Easy and fast change for welding moulds
  • Works effectively by compressed air supplied to the system

FAQ

What is a corner welding machine and what is it used for?

SCHTEC corner welding machines join the corners of PVC window and door profiles with 0.2 mm precision. Models like WD 710 and WM 740 ensure aesthetic and durable joints. With PID-controlled heat management and touchscreen interfaces, they standardize quality in window/door production.

SCHTEC welding machines provide 40% time savings and high efficiency through servo motors. WM 750’s 3-axis system and Teflon roll reduce maintenance needs. Used in over 65 countries, these machines optimize production with remote service and a 10,000-profile memory bank.

SCHTEC corner welding machines are compatible with all standard PVC profiles. The WDV 724 operates at 45°, 90°, and V-angles, while the WD 710 offers flexibility from 30° to 180°. They deliver uniform heat distribution for white and colored profiles, and adapt to various frame sizes.

SCHTEC offers on-site installation and operator training post-delivery. Our 7-member service team from a 9,000 m² facility provides 24/7 technical support with centralized lubrication and remote connectivity, ensuring uninterrupted production.
