Plastic common surface treatment agent way there are many in which plating and painting is more common way, the following comprehensive introduction to the plastic surface treatment process:
A, frosted
Frosted plastic generally refers to the plastic film or sheet, extruded molding sheet when the molding rollers have a frosted surface, so that the plastic cooling process naturally form a pattern, this way is simple and fast, especially for transparent products better results. So that in the process of cooling the plastic naturally formed frosted pattern, this way is simple and fast, especially for transparent products have better results
second, polishing
Use of mechanical, chemical or electrochemical effects, so that the surface roughness of the workpiece is reduced in order to obtain a bright, flat surface processing methods. Plastic products generally use abrasive paper rolled up on plastic products for polishing, usually this is a step before spraying!
Three, spraying
Plastic spraying is mainly in the metal equipment or plastic products coated with a layer of plastic paint, and then coaxed to dry the operation, generally baked 10 minutes or so, thanks to the advances in paint to achieve the same effect, and now do not have to paste the paper as before. Spray paint can play a role in isolating the air, spray paint and is an insulator so can play a role in plastic products anti-aging anti-static, the most important thing is to have the appearance of plastic products themselves do not have the effect of the effect . In the plastic surface of the spraying process to solve the problem of poor adhesion between the substrate and the coating of paint is an effective method of Ii Sheng adhesion promoter to enhance the adhesion between the substrate and the coating of the solution to the problem of paint, the adhesion of up to 5B.
Four, silkscreen?
The printing plate is usually a square fine mesh screen, printing ink on the printing plate in the squeezing of the squeegee from the layout of the through-hole part of the leakage of the print to the substrate. The production of screen plate material has a variety of, for example, can be made of nylon (PA), polyvinyl acetate (CA), silk or metal mesh production and become. If PC (polycarbonate) is used for this surface treatment, the color performance will be very ideal.
Five, pad printing?
First, the design will be etched on the printing plate, the etching plate is coated with ink, and then through the silicone head will be most of these inks transferred to the printed object.?
Six, thermal transfer
The design will be pre-printed on the surface of the transfer film film, through the thermal transfer machine a process (heating and pressure) will transfer the transfer film on the surface of the product of the exquisite design, molding the ink layer and the surface of the product as a whole, realistic and beautiful, and greatly improve the product's grade. However, due to the high technical content of the process, many materials need to be imported. Thermal transfer process is applied to all kinds of ABS, PP, plastic, wood, coated metal and other products surface?
Seven, water transfer:
It is the use of water pressure will be with a color pattern of the transfer paper/plastic film for polymer hydrolysis of a printing.
eight, laser engraving
The use of laser energy will be processed into the surface of a "trace", revealing the surface of the next layer of material, according to the needs of the lettering or pattern.
Nine, electrophoresis (water electroplating)
Metal electrodeposition technology technology, one of the metal cladding process, usually chromium, zinc and other metals through electrochemical deposition layer on the surface of the workpiece. Make the outside of the plastic parts become metallic, and make the material corrosion-resistant wear-resistant each with decorative and electrical, magnetic, optical properties. Plating process in the common material is ABS and PC, etc., but due to the material in the injection molding process, if the use of mold release agent or mold oil stains on the surface of the material, resulting in oil spots and oil spots and other phenomena, an effective solution is Gui Sheng plating oil treatment agent, cover the material surface oil, instead of white oil immersion cleaning to enhance adhesion, to solve the problem of oil spots and oil spots and other issues.
Ten, vacuum coating?
In the vacuum chamber of the material from the heating source of the atoms separated from the plated object on the surface, this method can obtain dazzling effect, applicable to ABS, PC plastic products. At the same time, because of its complex process, environment, equipment requirements, generally applicable to large quantities of products.
Xi, bite flower (etching, leather) for plastic mold
The use of concentrated sulfuric acid on the plastic molding mold internal corrosion, the formation of serpentine, etching, ploughing, wood grain and other forms of grain, plastic molding through the mold, the surface has the corresponding grain.
