First, please click here to leave your request and contact information.
Then, our sales staff will contact you later to learn about your specific welding materials, thickness, working size, usage, etc. They will recommend the most suitable welding equipment according to your situation and give you a quotation.
After we agree on the welding equipment and contact terms through negotiation, we can arrange the production process after you pay the deposit.
You are welcome to communicate with our sales staff via text, phone or video call at any time to check the production progress of your welding equipment.
Yes, we offer 1 year warranty. During the warranty period, if the machine is damaged by non-human factors, we promise to replace it with new parts for free.
Normally, our fiber laser cutting machine production lead time is 25-30 working days. The production cycle will vary depending on the machine required. Our sales staff will keep in touch with you to keep you informed of the latest developments.

Certainly. We have shipped many machines to many countries and regions. For example, the United States, Mexico, Australia, Italy, Indonesia, Brazil, Serbia, Canada, Russia, Kenya, etc.
We will establish a chat group composed of 4-5 MM-Tech technicians and after-sales personnel to provide you with online technical support and guidance. If you still have difficulty installing and using your laser cutting machine, we also provide on-site technical training.
You are not allowed to lay down the jointed pipes on the ground after fusion welding. The jointed pipe should stay in the machine with/without pressure (according to different welding norms) until the cooling time ends.
The proper cooling time varies depending on the pipe material, pipe diameter, and wall thickness. You could always find the cooling time from MM-Tech operation manual for butt fusion welder.
It varies depending on the pipe material and welding norms. Please consult the pipe manufacturer's recommended parameters.
Drag pressure is the pressure to overcome the friction during machine carriage movement. It should be added to the total fusion pressure.
You are always requested to measure the drag pressure with pipes stayed in the machine. Simply speaking, completely open the machine carriage, zero the pressure in the hydraulic system, close the pressure relief valve, then push the direction lever to maximum and gradually rotate the pressure regulated valve in a clockwise way until the machine carriage gets in motion. The current pressure shown on the gauge is the drag pressure. For more details, please refer to MM-Tech operation manual for butt fusion machine.
Butt welding machines are suitable for most thermoplastic materials, which soften when heated and solidify when cooled.
The following are commonly used types of plastics suitable for hot melt welding:
Polyethylene (PE): Polyethylene is a common thermoplastic material used extensively in the manufacturing of plastic bags, bottles, containers, and pipes.
Polypropylene (PP): Polypropylene is another widely used thermoplastic material suitable for automotive components, electronic devices, medical instruments, and more.
Polyvinyl Chloride (PVC): PVC exhibits excellent chemical resistance and heat resistance, making it applicable in construction, wire and cable, pipe manufacturing, and other industries.
Polystyrene (PS): Polystyrene is commonly used in packaging, insulation cups, household appliance casings, and other manufacturing applications.
Polycarbonate (PC): Polycarbonate offers outstanding impact resistance and transparency, making it popular in the electronics, optical, and medical fields.
Butt fusion welding is not suitable for thermosetting plastics, as these materials undergo irreversible curing after being heated and cannot be softened again. Common examples of thermosetting plastics include epoxy resins, phenolic resins, and unsaturated polyesters. Since thermosetting plastics cannot be re-softened, they cannot be joined using the hot melt welding method.
Before butt welding, the pipe ends must be rounded and aligned. A pipe roller support will give more help in alignment and reduce the drag pressure. When the mismatch of the pipe walls is still out of local regulation, please adjust the clamping jaws by tightening down the high side until the pipe ends are even.
Replacing the blade not depends on a certain period. But you should replace it when two sides of the blade are blunt or chipped. The life of blade varies depending on the hours of operation, material being face, periodical maintenance, etc.
