Product description: Injection Molding screen printing -called secondary processing is in China plastics injection molding company
Screen Printing Injection Molding in China
Printing plastic parts, plastic products, secondary mechanic (or reprocessing) one. The so-called secondary processing is in the plastics injection molding, once again decorative surface treatment. Such as plastic plating, plastic coating, plastic stamping, plastic printing, and so on. So to secondary plastics processing, mainly by the performance of the plastic itself, the decision. Such as dying is relatively simple, and the color of the light fastness is also poor. To compensate for these shortcomings, improving the appearance of decorative plastic products, on the need for secondary processing.
Plastic injection molding components of electronic products screen printing electronic products, especially radio products such as radios, tape recorders, televisions, etc., for the appearance of the requirements are high. After the plastic screen printing development for decoration brings the convenience of electronic products, so in recent years, a variety of electronic products, domestic plastic silkscreen been widely used.
Screen-printed plastic injection molding signs in China companies in recent years, after the plastic signs and plastic molding decorative silkscreen graphic text components, developed rapidly. As in PVC hardboard (PVC plates), polycarbonate, ABS, acrylic, modified polystyrene plastic pieces were pressed on the screen printing, has been widely used, and achieved the good decorative effect and Economic Benefit
Soft and hard plastic injection molding parts screen printing
① Plastic hose of silk.
There are several ways to print plastic hoses, the main method of the heat transfer method. A thermal transfer method is a sublimation dye ink or other material, the graphics printed on the transfer paper before and then bonded together with the substrate, the transfer sheet is heated from the back so that the dye sublimation and the paper Graphic transferred onto substrates. After the surface treatment of the plastic hose, a hose and a piece of transfer paper from between the heated iron by heating iron transfer paper into the hose, heated to complete the transfer. After the transfer tube into the drying apparatus, the drying temperature is generally about 65 ℃.
② Soft plastic molding screen printing.
Used for the production of soft plastic injection mold toys, such as inflatable cartoon toys. Usually the first on the soft plastic sheet printing pattern, then cut, the production of synthetic heat. The material thickness is 0.8 ~ 3.0mm. If the screenprints two or more colors, most plastics have a telescopic, second track error occurs chromatic color and the first color. This chromatic error commodity lost its value cannot be qualified as shelves. To this end, multi-color printing can only be taken.
Soft plastic can be fixed with a long press and no other way. For long-Taiwan printing, adhesive substrates to used fixed. You must use non-toxic toy printing standards prescribed harmless ink.
③ Rigid plastics molding printing.
There are two types of hard rigid plastics sheet and a molded article. Tickets, signs, instrument dials, cosmetic containers are made of hard plastic.
