Plastic toys are colorful and have great ornamental value. The processing materials of plastic toy manufacturers are environmentally friendly and harmless plastic materials. The reason for rich colors is the coloring process. What coloring methods do plastic toy manufacturers have?
The compound coloring technology can produce accurate, highly reproducible, deep and shallow injection molding products, suitable for small batch production.
The masterbatch coloring method is divided into granules and liquid processing, which are made by mixing plastic and masterbatch together and conveying them to the machine for processing. Its advantages are less dust, low raw material cost, and convenient storage.
The dry toner coloring method is also relatively cheap, and the vacuum color is uniform and accurate when used. You can use a specific size bag or carton to load the correct amount of dry toner.
When colored with dry toner, the surface of plastic toy particles needs to be covered with a layer of uniform colorant. The compounding method should be more accurate. After the coloring step is fixed, it must be operated step by step.
