The hot-melt welding machine is mainly suitable for the welding of plastic parts such as household appliances, lamps, car dissolvers, etc. The heating power and mold size can be set according to different plastic parts to realize welding of various plastic workpieces, which is easy to operate and convenient to use. What are the common methods of hot-melt welding? Please see the information for you.
1, welding method
Ultrasonic vibration is transmitted to the weldment with the welding head. Since the sound resistance of the two weldments is large, local high temperature is generated, and the weldment interface is melted. Under a certain pressure, the two weldments achieve a beautiful, fast and strong welding effect.
2, implant (insert) method
A nut or other metal is intended to be inserted into a plastic workpiece. First, the ultrasonic wave is transmitted to the metal, and after high-speed vibration, the metal object is directly buried in the molded plastic, and the plastic is melted, and the solidified material is buried.
3, molding method
The plastic workpiece is instantly melted by ultrasonic waves, and the plastic of metal or other materials can be solidified when the plastic solidifies.
4, the method of resection
Using the special design method of the welding head and the base, when the plastic workpiece is just shot, it is directly pressed on the branches of the plastic, and the effect of cutting is achieved by ultrasonic conduction.
5, riveting method
If you want to join metal and plastic or two plastics with different properties, you can use ultrasonic riveting method to make the weldment not easy to be brittle, beautiful and strong.
6, spot welding
The small welding head is used to weld two large plastic products by spot welding, or the entire toothed welding head is directly pressed on two plastic workpieces to achieve the spot welding effect.

PU Floor Profiles are widely used to decorate at the foot base of the wall.
Without PU Floor Profiles, the transition from floor to wall looks unfinished and bare and allows walls to be easily damaged. Skirting Boards are more than just decoration. It protects the wall, hides cracks and sometimes also covers expansion areas for parquet floors. You can choose the skirting board that matches the architecture of the room with your own style and size of the room. You can paint it(Floor Skirting,Skirting Boards,Aluminum Floor Profiles,Floor Trim Profiles,Baseboard Moulding,wall baseboard) to achieve the perfect color with other decorations.
