Laser welding machine is a popular product. Laser welding equipment has multiple functions and performance. Laser welding machines are widely used in various industries, greatly improving the company's work efficiency and production volume. Laser welding equipment has various characteristics and uses.
There are generally two methods to link materials together: bonding and welding. Generally speaking, the bonding process has low production efficiency, is not aesthetically pleasing, and the adhesive has a certain degree of toxicity; The welding process has relatively high production efficiency, beautiful weldments and high welding strength, so plastic welding process has been more and more widely used.
In the actual production process, only thermoplastics with the same or similar molecular structure can be welded. On the welding surface, there is a chemical bonding between molecules, so the closer the parent material is, the better the welding effect. At the same time, the content of fillers in plastic is closely related to its weldability and welding quality, as they alter the physical properties of the material. When the filler content exceeds 30%, due to insufficient proportion of surface plastic and insufficient fusion between molecules, the sealing performance of the welding will be reduced.
After selecting the correct weldable material, appropriate welding methods should also be adopted based on the type of material, product shape, and cost.
