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.
What are the advantages of a PVC window welding machine?
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.
Which profiles are compatible with automatic welding machines?
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.
How is a SCHTEC welding machine installed?
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.
