SHZ1GC-140Heavy-Duty Single-Head Double-Sided Seamless Welding MachineView detailsWhat is this machine used for?
A uPVC welding machine heats and joins mitred profile corners under controlled temperature, pressure and timing. Buyers should select the head count, welding height and control configuration around their profile system, production volume and required corner finish.
Buyer checkpoints
- Number of welding heads and supported frame sizes
- Profile height, fixture compatibility and welding pressure
- Temperature control, seam limitation and production cycle
Buyer FAQ
What is the difference between double-head and four-head uPVC welding machines?
A double-head machine welds two corners per cycle, while a four-head configuration can weld a rectangular frame in one cycle. The appropriate choice depends on output, frame-size range and changeover requirements.
Does every welded uPVC frame need corner cleaning?
Conventional welding leaves a bead that normally requires corner cleaning. Seam-limiting or seamless processes can reduce finishing work, but compatibility depends on the profile surface and specified joint appearance.
Which data should be supplied before selecting a welder?
Provide profile cross-sections, minimum and maximum frame sizes, welding height, surface finish and required output so fixtures and process settings can be reviewed.
