Ultrasonic Puncture Welder with High Efficient and Firm Automobile Spoiler
Ultrasonic waves propagate in plastic parts. Plastic parts absorb or attenuate ultrasonic energy more or less, which has a certain influence on the ultrasonic processing effect. Plastics generally have the distinction of amorphous materials, and hard rubber and soft rubber according to hardness. There is also a distinction between the modulus and, in a nutshell, the high-hardness, low-melting plastic ultrasonic processing performance is superior to the low-hardness, high-melting plastic. Therefore, this involves the near-far problem of ultrasonic machining distance.
Generally speaking, the molecules of different plastic raw materials are different, and the effect of using ultrasonic plastic welding machine will be different. Therefore, we must use materials with high ultrasonic weldability, such as: ABS, PC polycarbonate, etc. material. In addition, product smoothness also has an impact.
The weld line is the part of the direct melting of the ultrasonic wave, and its design effect directly affects the appearance of the final product and the production process.
Since plastic products should consider the watertightness and airtightness of the products, when selecting the machine, we should select some experienced manufacturers to customize the production plan for the products, improve the welding efficiency, and avoid plastic melting or compound overflow.
1. Conclusion of auto internal and external parts puncture welding.
Design lateral thickness is not less than 3 mm, inner layer thinner than the outer, the error range can be plus or minus 0.3 mm. We can design positioning groove or ultrasonic welding line can be designed to assist welding.
2. How to use ultrasonic puncture welding technology?
It was decided by product material, best of same material, or a mixture of materials and other materials. It depends on whether the ultrasonic wave of two kinds material can be fused. You can send the material to try to test.
