With the development of science and technology, plastic products are no longer just buckets, baskets, pots and bowls on roadside stalls, but are widely used in high-tech, sophisticated and cutting-edge fields such as automobiles, electronics, medical devices and even aerospace. To be applied in these fields, in addition to the plastic itself must meet the requirements, but also to solve the problem of processing.

  In the traditional machining mode, the drill bit and other machinery act directly on the plastic workpiece, which is easy to deform the plastic workpiece, and will form the edge in the processing place. It also needs some treatment, and the precision often fails to meet the requirements. The processing speed is also relatively slow. The application of laser technology in plastic processing can avoid the above disadvantages, greatly speed up the research and development of new plastic products, and make plastic applications into the field of "high, fine and sharp" application. Laser is to focus light energy through the laser to form a laser beam, accurately send huge energy to very small areas, so that a variety of materials, including plastics, welding, cutting, carving, marking, drilling and other processing.

  How to achieve precision, cleanliness, speed and efficiency in the process of welding, cutting, engraving, drilling and so on has become an urgent problem in the plastic processing industry.

  Plastic medical equipment is often some very small products, such as catheter hole diameter can only be 0.3 mm, vascular molding, catheter aperture is between 0.0076~0.025 mm, such a small plastic pipe to be processed, There is no other way than using a laser.

  Laser processing is non-contact processing, no mechanical impact on the workpiece itself, the workpiece will not deform; small thermal impact area, the workpiece is not easy to produce residual thermal stress; laser beam focusing positioning can be switched at any time, combined with computer programs, Its energy and trajectory can be precisely controlled to complete precision and complex cutting and drilling; it can also operate in the process of workpiece movement, automation, greatly improve production speed; using laser welded joints firmly durable and clean, weldable modified rubber and glass fiber filled thermoplastic plastics. Laser marking is to form a certain mark on plastic parts by laser, which can also overcome the problem that mechanical marking changes the surface quality of materials and is easy to breed bacteria.

  Now some plastic molds are also miniaturized, the laser has non-contact, wear-free and accurate positioning characteristics are obviously very suitable for the engraving of these micro molds.
