The working principle of ultrasonic welding machine:
When the ultrasonic wave acts on the thermoplastic contact surface, it will produce tens of thousands of high-frequency vibration per second. This high-frequency vibration reaching a certain amplitude will transmit the ultrasonic energy to the welding area through the upper weldment. Because the welding area is the interface of two welding, the sound resistance is large, so it will produce local high temperature. And because of the poor thermal conductivity of plastics, short-term can not be timely distributed, gathered in the welding area, resulting in the rapid melting of the contact surface of the two plastics, plus a certain pressure, so that it is fused into one. When the ultrasonic wave stops acting, let the pressure continue, so that it solidifies and forms, so as to form a strong molecular chain, to achieve the purpose of welding, welding strength can be close to the strength of raw materials.
1. Fusible thermal plastic;
2. The welding time is very short, usually within the range of 0.05-1 seconds;
3, ultrasonic welding will not produce toxicity such as chemical agents, for a safe welding processing;
4, without adding any adhesive, the operation is simpler and faster;
5, through the medium such as water, oil and other fused to the joint surface;
6, welding effect, can reach air tight, liquid tight sealing effect;
7, can be used for direct and conduction fusion;
8. The welding energy varies according to the plastic material, so there is no concern about scars on the product surface. When the hard plastic is fused, the fusion effect can be played more effectively.
