Nowadays, in response to environmental protection requirements and lightweight trends, plastic products are gradually replacing the metal parts of industrial products. As parts of industrial products, welding is inevitable. But the traditional plastic welding technology has many disadvantages. The laser welding technology is a welding method that uses a high-energy density laser beam as a heat source. Today, Leapion Laser introduces the advantages of laser welding machines in plastic products.

Traditional plastic welding technology has many problems, such as: grooves are prone to appear in the transition position of the weld, or the weld penetration directly affects the use quality of the entire workpiece, and some cracks, deformations, and bubbles due to different welding materials or processes , Chromatic aberration and other issues.

As a technology for welding plastic products, laser welding is mainly used to connect sensitive plastic products, such as circuit boards, electronic sensors of plastic parts, plastic products with complex shapes, and plastic products that require strict sealing and cleanliness, such as medical devices. .

Application advantages of laser welding technology in plastic products:

1. Laser welding technology belongs to non-contact welding:

The laser welding machine does not have physical contact when welding workpieces, does not chemically react with thermoplastics, and will not be affected when operating in an industrial environment.

2. Laser welding technology can adjust the shape and size of the laser beam:

Computer control can be used to precisely weld processed objects, control the size of the joint area and the heat-affected zone, with high degree of freedom, flexible operation and easy control;

And there are no restrictions on the size and shape of the parts that need to be welded, and each part is welded finely.

3. Good appearance:

The laser welding machine has fast welding speed, high strength, no flash and no residue.

4. The laser welding technology hardly produces welding slag and debris, and there is no need to add any adhesive during the welding process, so the entire welding work can be completed in a clean room.

5. Compared with traditional welding, laser welding is very strong, has the characteristics of airtightness, airtightness, and watertightness. During the welding process, the resin is less degraded and produced less debris, which tightly connects the plastic products.

6. Laser welding greatly reduces the vibration force and thermal stress of plastic products, thereby delaying the aging speed of plastic products.

With the increasing requirements for plastic products in different industries, it is difficult for traditional processes to meet the current processing needs. For plastic products that require high-speed welding, precision welding or aseptic welding, laser welding is more advantageous.

With the changes in market demand, plastic products now have different types and colors. However, laser welding can achieve higher welding firmness by adding various pigments to the weld during the welding process.
