What Are The Requirements Of Ultrasonic Welding For Plastic Materials?
Ultrasonic welding is widely used in handicrafts because of its easy operation, low cost and mature production process. However, not all welding materials can be used, and some materials have limitations, which may be misunderstood. Let's talk to you about the material properties of welding materials, which may be helpful to you.
Generally speaking, ABS material is the easiest to weld, and nylon is the most difficult to weld.
The materials that are more difficult to weld are: PPS: because the material is too soft, it is very difficult to weld. Polyethylene, referred to as: PE; this material is relatively soft, so it is not easy to weld, and the difficulty of welding is relatively reduced with high density.
Polyvinyl chloride, referred to as: PVC; therefore, the material is soft and difficult to weld, so few people use this material, and the products of this material are generally welded with high frequency waves.
Polycarbonate, abbreviated as PC; high melting point and long welding time. Polypropylene, referred to as: PP; this material is difficult to weld due to its low elastic coefficient, which is easy to attenuate sonic vibration. Nylon, abbreviation: PA
Polyoxymethylene (POM). Polymethyl methacrylate, referred to as: PMM.
Acrylonitrile-styrene copolymer (A/S). Polyester (PETP polybutylene terephthalate, PBTP polyethylene terephthalate).
ABS material has superior processability, appearance characteristics, low creep and excellent dimensional stability and high impact strength.
Polystyrene (PS) has light specific gravity, strong corrosion resistance to water and chemicals, good stability and insulation, especially suitable for injection and extrusion molding, commonly used in toys, decorations, washing equipment, pans, lenses, Manufacture of floating wheels, etc. Due to its high elastic strength coefficient, it is suitable for ultrasonic welding.
The properties of the material will affect the effect of welding, and it also needs to be determined according to the actual situation. Most of the welding materials mentioned above are not easy to weld. You can also compare them to see if you have any knowledge of those materials.
