What are the requirements for plastic materials in ultrasonic welding?
Ultrasonic welding is widely used in handicrafts because of its easy operation, low cost, and mature production technology. However, not all welding materials can be used, some materials have limitations, and everyone may misunderstand. 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: The material is too soft and it is very difficult to weld. Polyethylene, abbreviated as: PE; this material is relatively soft so it is not easy to weld, and the welding difficulty is relatively reduced due to high density.
Polyvinyl chloride, abbreviated as: PVC; therefore, the material is relatively soft and difficult to weld, so few people use this material, and products of this material are generally welded with high frequency.
Polycarbonate, abbreviated as: PC; high melting point, long welding time required. Polypropylene, abbreviated as: PP; this material is easy to attenuate sound wave vibration due to its low elastic coefficient, and it is difficult to weld. Nylon, abbreviation: PA
Polyoxymethylene (POM). Polymethyl methacrylate, abbreviation: PMM.
Acrylonitrile-styrene copolymer (A/S). Polyester (PETP polybutylene terephthalate, PBTP polyethylene terephthalate).
ABS material has super easy processing, appearance characteristics, low creep and excellent dimensional stability and high impact strength. Polystyrene (PS) has a light specific gravity, strong corrosion resistance to water and chemicals, stability, and good insulation. It is especially suitable for injection and extrusion molding. It is often used in toys, decorations, washing equipment, pans, lenses, Manufacturing of floating wheels, etc. Due to the high elasticity coefficient, it is suitable for ultrasonic welding.
The properties of the material will affect the welding effect, and it 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 and see if you know about those materials.
