01 / FUNCTION & PROCESS

What does this machine do?

Welds uPVC profiles into window or door frame assemblies using a four-head arrangement. It is the joining stage before any required corner cleaning and final assembly.

What to review before selecting

  1. Provide the uPVC section, surface finish and frame dimensions.
  2. Agree the joining or cleaning method and matching tooling.
  3. Inspect a sample joint or corner before accepting the process.
02 / SELECTION ADVANTAGES

Why consider SHJ4-120*4500?

The documented 400–4500 mm welding-length range supports a frame-size shortlist. Compare the weld process with the WFH series using samples rather than assuming the same laminated-surface finish.

Jinan Smatech Machinery Enterprise Co., Ltd. can review your requirement against this catalogue configuration when preparing a quotation.

How to read these specifications

Working width, height and frame or processing length are separate limits. Check all applicable dimensions against your profile system.

A model designation is an identifier, not a substitute for the documented working range or an accepted sample.

Standard & optional configuration

The catalogue does not provide a separate confirmed standard/optional supply list. Tooling, electrical compatibility, software where applicable, installation and service scope are confirmed with the quotation.

Request a written supply list for your model, including tooling and any project-specific accessories.

CHECK THE FIT

Start with your profile.

Profile section and finish; frame sizes; joint design; welding/cleaning samples and required output.

Include a representative part drawing, required finish, target output and workshop power supply. This allows the quotation to address the actual machine configuration.
