Core Tip: Since the reform and opening up, the plastics industry has been developing continuously, rapidly and healthily for more than 30 years. However, the arrival of the international financial crisis has led to different levels of contraction in various industries around the world. The global demand structure is facing positive changes, and it is bound to trigger a reshuffle of the plastics industry. The plastics industry must reduce production and manufacturing costs, shorten the development cycle, and improve the core competitiveness of the plastics industry in order to completely defeat the current global financial crisis in the past few decades.
Laser processing refers to the use of the thermal effect generated by the laser beam projected onto the surface of the material to complete the processing, including laser cutting, laser engraving (laser marking).
Due to the high brightness, high directivity, high monochromaticity and high coherence of the laser, the laser processing plastic products bring some excellent characteristics not found in other common processing methods.
The detailed application of laser processing in the plastics industry is as follows:
First, laser cutting plastic products:
Plastic laser cutting is to focus the laser beam on the surface of the plastic material, use the high temperature characteristics of the laser to melt the material, and use the compressed gas coaxial with the laser beam to blow away the melted plastic product, and make the laser beam and the plastic product along a certain trajectory. Performing relative motion to cut a process that forms a shape.
The advantages of plastic laser cutting processing:
Detailed application of laser cutting plastic products:
1. Laser cutting plastic nozzle: laser cutting quality is good, it belongs to non-contact cutting, the edge is affected by heat very little, there is basically no thermal deformation of the workpiece, completely avoiding the collapse formed when the die is punched, the laser slit is smooth and flat, generally not Need secondary processing.

2. Laser cutting processing to produce new samples of plastic products: laser cutting processing can improve the speed of new product development: after the product drawings are formed, laser processing can be carried out immediately, and samples of new plastic products can be obtained in the shortest time.

3. Laser cutting and plastic products: saving plastic mold investment: plastic laser cutting processing does not require molds, no mold consumption, no need to repair molds, saving mold time, thus saving processing costs, reducing production costs, especially suitable for large Processing of products or small batches of plastic products.

Second, plastic products laser engraving:
Plastic laser engraving is the laser processing process that uses the high energy density of the laser to illuminate the surface of the plastic product, vaporize the surface material of the product and produce a clear pattern.
Detailed application of laser engraving plastic products:
1. Laser engraving processing product logo: laser engraving product logo, with very clear and delicate features, and has the strength of never wear.
2. Laser engraving and processing of plastic product pattern: laser engraving processing, can engrave and process any complex pattern, the pattern effect is clear and delicate, and has other advantages that cannot be compared with other processing methods.
