Application of Laser Welding Machine in Plastic Welding Technology

Due to the unique chemical properties of plastics, traditional plastic welding techniques often encounter various problems. For example, the transition position of the weld seam is prone to grooves, or the penetration depth of the weld seam directly affects the overall quality of the workpiece, which may lead to problems such as cracks, deformation, bubbles, and color difference. Therefore, with the development of technology, laser welding technology has been widely used in plastic welding. Below, we will introduce the technical application of laser welding machines in plastic welding.

The laser welding machine uses the heat generated by the laser beam to melt the plastic contact surface, thereby achieving the bonding of various plastic materials such as acrylic, plastic, film, rubber, or molded parts. Compared with traditional welding techniques, plastic laser welding technology has significant advantages, as it can tightly connect two plastic surfaces and avoid problems such as burrs, deformation, or bubbles. In addition, using laser welding machines through repair welding and repair can significantly reduce the cost of enterprises.

Laser welding machines face the challenge of transparent and semi transparent materials during laser penetration welding, especially PC to PC welding widely used in medical equipment. Due to the fact that both the upper and lower plastics are parts that can be penetrated by laser and lack absorption layers, if plastic laser penetration welding technology is to be used, it is necessary to apply a light absorbing agent at the weld seam to absorb laser energy and melt it to achieve welding. However, this process is rarely used by customers for mass production, partly because the use of laser absorbers increases additional consumable costs and thus increases production costs; On the other hand, adding spraying processes in the production process can also bring equipment, consumables, and manufacturing risks.

In recent years, with technological advancements, laser welding machines have solved the welding problem of transparent plastics. This method is based on the principle that lasers of different wavelengths have different penetration and absorption characteristics for plastics.
