Ultrasonic welding machine - automotive application to the welding process!

 The welding process applied to the automotive industry is more extensive, and several types of welding process are now shown. A plastic product is likely to be made of a variety of raw materials or components, to integrate the components, can be used mechanical equipment fixed cards, adhesives and welding processing process production.

In the three tight connection methods here, the mechanical equipment fixing card can connect the two parts faster, but the leakage filling effect of the joint is weak, and some ground stresses will easily get rid of the middle of the polymer raw materials; Adhesives can produce seams with excellent leak-filling effect, but their difficulty in solving is relatively large, and the drying speed is relatively slow.

At the same time, when adhesives are used for bonding, the requirements for joint preparation procedures and surface hardness are higher; The actual effect of the welding process is good, which can cause a solid bonding joint, its scientific characteristics are close to the raw materials of the pregnant mother, and a variety of forms of welding, which can be selected according to different raw materials, on and function.

Plastic welding can be divided into two categories

First, the mechanical equipment mobile welding processing technology: including ultrasonic welding, friction welding and vibration welding;

Second, it is the external heating welding technology: including hot plate welding machine, heat flow welding and embedded welding.

According to the different heating methods, it can also be divided into heating special tool welding, magnetic induction welding ultrasonic welding, high frequency welding, hot plate welding, laser welding, vibration friction welding, infrared induction welding, hot pile welding and warm air welding.

To put it plainly, the welding of plastic parts is to use the method of electric heating to melt the appearance of two thermosetting plastic parts at the same time, and fuse the two parts into one under the action of the external force.

In many car exterior decoration parts, interior decoration design parts, function parts and parts, plastic products can be seen everywhere.

The replacement of traditional metal composite materials by plastics has achieved a very obvious practical effect of fat reduction, which has key practical significance in saving resources and reducing pollutant discharge.

At this stage, plastic welding technology has been successfully applied to automobile bumper, automobile dashboard and in-car dashboard, reverse lights, gas car auxiliary tools, automobile door frame and other parts and components related to automobile engine manufacturing enterprises.

With the gradual replacement of many traditional metal parts with plastic, such as inlet pipe, instrument dial dial, heat pipe radiator structure reinforcement, automobile fuel tank and filter, etc., the application of new technology and technical scientific research in the plastic welding industry has achieved a good development trend opportunity, energy-saving, high efficiency, Fitchless and zero-pollution welding machinery and equipment will become the technical development trend of automobile welding network in the future.
