Common plastic properties that can be used for ultrasonic welding

Ultrasonic welding machines can weld many different materials of plastic rubber and plastic products. Because different materials require different ultrasonic equipment, we must have sufficient control of the raw materials before we carry out ultrasonic welding to achieve stronger The actual effect of welding. The following ultrasonic welding machine manufacturers will show you the characteristics of these materials that can be welded by the splicing machine.

1. General polyethylene:

Light ratio, strong corrosion resistance to water and organic chemicals, stable, good dielectric strength, especially suitable for injection and extrusion molding machines, commonly used in small toys, washing machines, decorations, lenses, pans, Manufacturing of wave wheels, etc. Because of its high elastic strength index, it is suitable for ultrasonic welding.

2. PP polypropylene:

It is light in proportion, has excellent dielectric strength, high compressive strength, can withstand high temperature and corrosion of chemical raw materials, and can be made into rope and other textiles after scraping. Products include small toys, suitcases, song cases, electrical equipment insulation, food packaging materials, etc. Due to its low elastic coefficient and easy attenuation coefficient, this material will vibrate at sonic frequency and is difficult to ultrasonic welding.

3. Polysulfone:

Hard quality, high compressive strength, arrogant, long-term exposure to heat does not harm its electrical performance, commonly used as TV parts, motor parts, etc. Due to the high melting point, higher kinetic energy welding is required.

4. PVC polyethylene:

Electric charge, resistance to weak chemicals, good ultra-low temperature, flame retardancy, commonly used in various types of plastic hoses, material films, etc., the material is soft, easy to attenuate the coefficient of sound frequency vibration, and the welding surface is very easy to burn.

5. ABS Acrylonitrile Butadiene:

The styrene prepolymer is light in weight, taking into account the properties of bremsstrahlung, rigidity and solvent resistance, and is mainly used for general purposes. This material has good heat transfer properties and is especially suitable for ultrasonic welding.

6. Ester acid weaving chemical substances:

When ultrasonic vibration, the material is easy to change and fade, the surface is not easy to digest and absorb kinetic energy, and it is difficult to melt.

7. Poly air oxidized xylene:

High temperature resistance, humidity resistance, chemical resistance, no fear of steam, commonly used as terminal blocks, motor rotors, casings, centrifugal impellers and pipes, etc. It has a high melting point and requires higher kinetic energy welding.

8. Acrylic:

High strength, resistance to slams, no acid effect, high-aspect ratio electron-optical clarity, excellent coloring, common in automobile taillights, medals, watch plates, tap door handles, etc. When using ultrasonic welding, you must pay attention to the problem of attenuation coefficient clarity.

9. Polyester:

The material is strong, anti-wear, low friction resistance, acid resistance, commonly used as rolling bearings, brushes, etc. When using ultrasonic welding, due to the high melting point, the welding time is long, and it will be easy to weld by drying before welding.

10. Polypropylene resin:

High temperature resistance, good light transmittance, high tensile and bumpy compressive strength, common in spectacle lenses, such as heat pipes, filter devices, etc. Due to the high melting point, the welding time is long. Because the material is absorbent, it must be dried before welding.

11. Polyphenylene ether:

Good electric charge, increased insulation layer degree, commonly used as electronic parts. Due to the high melting point, the welding time is long and the vibration amplitude is high.
