Plastic laser welding machines are crucial in medical device applications

In today's industrial field, the application of laser equipment is becoming more and more important. In the field of medical device manufacturing, laser equipment can be seen from industry to life, such as medical devices closely related to human health, in which plastic laser welding machines play an important role. Now let's take a look at the relevant details.

Plastic laser welding machines are mainly used for the connection of medical device components in the field of medical device manufacturing. What are the functions and working principles of these plastic laser welding equipment? You will get the following answers.

Plastic materials are ideal materials for many manufacturing industries: easy to mold, easy to clean, light weight, high temperature sterilization and other excellent properties, very suitable for many fields. So far, two injection molded parts are usually connected by chemical reaction, thermal effect or mechanical process, depending on the later application of the product and the different requirements for visual aesthetics. However, connecting plastic parts in a harsh environment is a huge challenge. The properties of the surrounding materials will change without dust and chemicals. When the connection quality of plastic parts is very demanding, the connection must be very strong and clean. When there is no dust and chemicals, the advantages of plastic laser welding technology will be revealed. With its advantages of high reliability, high speed, high precision, flexible processing and beautiful appearance, plastic laser welding technology has gradually occupied most of the plastic equipment processing application market and has become an important processing method in the medical engineering industry.

The working principle of the plastic laser welding machine is relatively simple. It is mainly that the laser beam passes through the upper light-transmitting material to the surface of the lower absorption material. The laser energy enters the heat energy to melt its surface. At the same time, the heat is conducted from the bottom plane to the upper light-transmitting component and contacts with the pressure head to dissolve it, realizing laser hot melt welding. A large number of verifications have been carried out through a large number of welding process quality control methods. After the narrow slit is cooled, it is consistent with the strength of the material itself.

Plastic laser welding can produce welds that are almost as strong as the material itself, without generating debris and dust, and without the need to introduce chemicals or other additives. Clean the entire process. When welding, the welding accuracy is between a few millimeters and several millimeters. Especially when the weld structure is fine and beautiful, plastic laser welding is undoubtedly an ideal process.

Due to the particularity of its use, the production of medical devices requires more fineness and precision. The general requirements of medical devices are sterility and no chemicals are added, while traditional bonding methods introduce chemicals into analytical instruments, thereby affecting the accuracy of the analysis. Other welding methods such as friction welding will generate dust or overflow during processing, thereby contaminating the instrument. But compared with other commonly used welding processes, the plastic laser welding process basically does not generate welding slag and debris, has less adhesive, and can be fully welded in a clean room. The introduction of plastic laser welding technology has greatly promoted the development of medical devices.

Plastic laser welding machine has good advantages in the production of plastic medical equipment, and it is also an important process for connecting plastic parts in the precision field. Its advantages are clean, burr-free, high strength, and no change in material properties when welding plastic parts. The high reliability of the production process is fully guaranteed, making laser plastic welding the preferred connection technology for a variety of applications in medical engineering. Therefore, the application of plastic laser welding machine in the field of medical equipment is crucial.
