Although when plastic products are formed, the product will be original color and grain. But in order to improve the life of plastic mold and product life, one.
The surface of plastic products will be reprocessed and processed.
What are the types of plastic surface treatment?
Grinding plastic is generally used to refer to plastic film or sheet material, when extruding sheet material, the surface of the molding roller has frosted pattern, so that the plastic cooling.
In the process, it is natural to form frosted pattern, which is simple and quick, especially for transparent products.
Second, the polishing
Using mechanical, chemical or electrochemical functions to reduce the surface roughness of the workpiece to obtain a bright, flat surface processing method. Plastic products
It is generally used to polish the plastic products, which is usually the first step of spraying.
Plastic spraying is mainly on the metal equipment or plastic products coated with a layer of plastic paint, and then coax dry operation, generally bake about 10 minutes, benefit.
The progress of the paint, to achieve the same effect, now do not have to paste the paper as before. Spray paint can be used to isolate the air, spray paint is unique.
The edge body can play the role of anti-aging and anti-aging of plastic products, and the most important is the appearance effect that the plastic products themselves do not have.
Four, silk screen
The printing plate is usually small screen mesh, printing ink on the printing plate under the extrusion of the section through the hole part of the printing to the substrate. system
There are many kinds of screen materials, such as nylon (PA), polyvinegar (CA), silk or metal mesh. If the PC (polycarbonate).
Using this surface treatment, the color performance will be ideal.
Five, the pad printing
The design is etched onto a printing plate, etched onto the etching board, and then transferred most of the ink through the silicone head to the printer.
Brush the object.
The design is pre-printed on the film surface of the transfer film, and the fine print on the transfer film is transferred to the product table by a heat transfer machine (heating pressure).
Surface, after forming the ink layer and product surface dissolve into one, lifelike and beautiful, greatly improve the product level. However, due to the high technology content, xu.
All materials need to be imported. Heat transfer printing process applies to various ABS, PP, plastic, wood, coated metal and other products surface.
