What is Two Colour Injection Moulding?

In simple terms, two colour injection moulding is a method that layers two colors of plastic in one product. By using this technique, manufacturers can create eye-catching designs. "Why not just use one color?" you might ask. Well, mixing colors gives a unique look and function to products.

How Does It Work?

The method involves several key steps:

1. Preparation: The first step is to choose the materials. Usually, two types of plastic with different characteristics are selected.
2. Injection Moulding Machine: A special two-shot injection moulding machine is used. This machine can inject two types of plastics into a single mould.
3. Mould Design: The mould is designed to accommodate both colors. This means the shape and space in the mould must be precise.
4. Injection Process: First, the machine injects the first color into the mould. After it cools slightly, the second color is injected.
5. Cooling: The entire mould is then cooled. This solidifies the plastics and bonds them together.
6. Demolding: Finally, the finished product is removed from the mould. And voilà! You have a beautifully designed, two-tone item.
