With the development of science and technology, plastic products are no longer just barrels, baskets, basins and bowls on street stalls, but are widely used in high-tech, sophisticated and sophisticated fields such as automobiles, electronics, medical devices and even aerospace . To be applied to these areas, in addition to the plastic material itself must meet the requirements, but also solve the processing problems.
How to achieve precision, cleanness, fastness and high efficiency in the process of welding, cutting, carving and drilling has become an urgent problem to be solved in the plastic processing industry.
The traditional machining method, the drill and other machinery directly on the plastic parts, plastic parts easily deformed, and will form a rough edge in the processing, but also need some processing, the precision often fail to meet the requirements, the processing speed is relatively slow . The laser technology used in plastic processing, to avoid the above shortcomings, greatly accelerate the speed of research and development of new plastic products, plastic applications into the "high, refined, sharp" areas. Laser is the laser light through the laser to focus the formation of a laser beam, the huge amount of energy precisely to a very small area, including plastic materials, including welding, cutting, engraving, marking, drilling and other processing.
Laser processing is a non-contact processing, the workpiece itself does not have a mechanical impact, the workpiece will not be deformed; heat-affected zone is small, the workpiece is not easy to produce residual thermal stress; laser beam focused positioning can be switched at any time, and the combination of computer programs Energy and trajectory can be precisely controlled to complete the work of precision cutting and drilling and other complex; it can also be moved in the workpiece during the operation, the processing automation, greatly increased production speed; the use of laser welding seam durable Clean, solderable hard-to-join modified rubber and fiberglass filled thermoplastics. Laser marking is to form a certain mark on the plastic parts by the laser. It can also overcome the mechanical marking and change the surface quality of the material, and is easy to breed bacteria. The marking is marked with high brightness and clear edges.
Plastic medical equipment is often some very small products, such as the diameter of the catheter hole only 0.3 mm, angioplasty, the catheter aperture is even between 0.0076 ~ 0.025 mm, so tiny Plastic pipe to be processed, except with laser no other way.
Now some plastic molds are also miniaturized. The laser's non-contact, wear-free and accurate positioning is obviously very suitable for the engraving of these miniature molds. 【Suzhou Mold Casting】
