Plastic products are used everywhere in our life. Plastic has won the love of consumers by virtue of its plasticity, impact resistance, coloring and insulation. Some plastics can also be re-shaped for use, which is conducive to resource protection and secondary utilization. Plastic has provided a great help to our life, and there are countless products made of plastic. The cost performance of plastic is extremely high, which is also loved by manufacturers. All kinds of plastic products, so, what are the surface treatment methods of plastic products factory and oh? Let's take a look!
First, scrub
Frosted plastic generally refers to plastic film or sheet, extrusion molding sheet when the surface of the forming roller has a frosted pattern, so that the natural formation of frosted pattern in the process of plastic cooling, this way is simple and quick, especially for transparent products have better effect
Two, polishing
The use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece, in order to obtain a bright, flat surface processing method. Plastic products generally use abrasive paper rolled up to polish plastic products, usually this is the first step of spraying!
Three, spray
Plastic spraying is mainly coated with a layer of plastic paint on metal equipment or plastic products, and then coaking dry operation, generally drying about 10 points, thanks to the progress of paint, to achieve the same effect, now do not need to paste paper as before. Spray paint can be used to insulate air. Spray paint is an insulator, so it can play the role of anti-aging and anti-static of plastic products. The most important thing is that it has the appearance effect that plastic products themselves do not have.
The effective method to solve the problem of poor adhesion between the substrate and the coating in the spraying process of the plastic surface is to increase the adhesion promoter to improve the adhesion between the substrate and the coating to solve the problem of paint dropping, and the adhesion force reaches 5B.
Four, screen printing
The printing plate is usually square and thin screen, and the ink on the printing plate is misprinted from the through hole of the plate to the substrate under the extrusion of the scraper. There are many kinds of materials for making screen plates, such as nylon (PA), poly (CA), silk or metal mesh. If PC (polycarbonate) uses this surface treatment, the color performance will be very ideal.
Five, pad printing
The design pattern is etched on a printing plate, the etching plate is coated with ink, and then most of the ink is transferred to the printed object through the silicone head.
Six, thermal transfer
The pattern is printed in advance on the surface of the transfer film, and the exquisite pattern on the transfer film is printed on the surface of the product through the thermal transfer machine (heating and pressure). After forming, the ink layer and the surface of the product are dissolved into one, lifelike and beautiful, and the product level is greatly improved. However, due to the high technical content of the process, many materials need to be imported. The thermal transfer process is applied to the surface of ABS, PP, plastic, wood, coated metal and other products
Seven, water transfer printing
It is a kind of printing that uses water pressure to hydrolyze the transfer paper/plastic film with color patterns.
Eight, laser engraving
The energy of the laser is used to treat the surface into a kind of "trace", exposing the layer of material beneath the surface, which can be engraved or patterned as needed.
Nine, electrophoresis (water plating)
One of the technologies of metal electrodeposition, usually using metals such as chromium and zinc to obtain a deposited layer on the surface of the workpiece by electrochemistry. Make the plastic parts outside the metal texture, and make the material corrosion resistance and wear resistance have decorative and electrical, magnetic, optical properties. The common materials in electroplating process are ABS and PC, etc., but because of the injection molding process of the material, if the release agent is used or the mold oil is stained on the surface of the material, resulting in oil spots, oil spots and other phenomena, the effective solution is Jiongsheng electroplating oil treatment agent to cover the surface of the material oil, instead of white electric oil soaking cleaning, improve the adhesion. Solve problems such as oil spots, oil pits and oil spots.
Ten, vacuum coating
In the vacuum chamber, the atoms of the material are separated from the heating source and hit the surface of the plated object. This method can obtain a dazzling effect, which is suitable for ABS and PC plastic products. At the same time, it is generally suitable for large quantities of products because of its complex technological process, high environment and equipment requirements.
The above is the common surface treatment of plastic products, I hope to help you! If you have any other questions, please consult us!
