If the fluorinated raw material in the plastic material, the spot welding method first extrudes the fusion splicing column (single point), and then supersonicizes the fusion splicing column to join the two parts (the ultrasonic line at the surface joint), the melting point is 263 degrees, The temperature should be in the scope of ultrasonic welding, but it has not been able to reach the level of adhesion after the fusion.
1. If the material is in the category of ultrasonic welding industry, but can not exceed the effect of fusion, it should be analyzed from several points:
a) welding extrusion molding standards (such as buffering, welding time, hardening is not the best setting);
b) Product positioning (suitable for positioning of the step male and female sets);
c) whether the ultrasonic waveguide fuse has commercial function requirements (such as normal, watertight, airtight, etc.);
d) Is the output kinetic energy of the ultrasonic welder appropriate?
2. All products are ultrasonically fused, and all are intentionally oscillated in advance. That is, when the upper die touches the workpiece about 3~5mm, the ultrasonic wave is first oscillated, and the descending buffer is adjusted to reduce the second stroke speed. This is the heating principle of the product fusion.
