Injection molds are now widely used. The injection molds on the market are colorful, and the colors are different, so how is the injection mold processing in Dongguan colored? The following is a brief introduction of the three commonly used coloring methods for injection molding in Dongguan Yuzhuo Injection Mold Factory. I hope it will be helpful to everyone.
- 1. The compound coloring method is the most accurate coloring technology for Dongguan injection mold processing, which can produce accurate, highly repeatable and appropriate shades, and is most suitable for small batch production. Most commercial plastics are colored on injection molding machines, while most engineering plastics are already colored when they are sold.
- 2. The masterbatch coloring method of injection mold processing is divided into two kinds of granules and liquid materials, which can be adjusted to various colors. Among them, pellets are the most common. The use of color masterbatch can be achieved by mixing plastic and color masterbatch, and actually conveying the mixture or color masterbatch into the injection molding machine. Its advantages are: cheaper colors, reduced dust problems, lower raw material costs, and more convenient storage.
- 3. The injection molding process of dry toner coloring method is the cheapest, its disadvantage is that it is dusty and dirty when used. To ensure uniform and accurate colors in the production process, bags or cartons of specific sizes can be used to load the correct amount of dry toner. When using dry toner for coloring, the surface of the plastic particles must be covered with a uniform layer of colorant, so that the color can be evenly distributed in the melt. The method and time of compounding must be standard to ensure uniform coloring. After the coloring step is determined, it must be persevered. In addition, it is necessary to prevent the toner from absorbing moisture during storage, otherwise it will easily break up and cause the injection mold to appear streaks.
It can be seen that the three methods of coloring injection molding molds have their own advantages. We need to choose the appropriate coloring method according to our products so that the processed products can meet our requirements, minimize costs, and maximize economic benefits. .
