The application of Crate Mould is quite extensive at present. The crates on the market are colourful and colourful, so how are the crates processed coloured? The following is a brief introduction to three common colouring methods for injection moulding, hoping to be helpful to everyone.

1. The colouring method of compound pigment is the most accurate colouring technology for crate mould processing. It can produce accurate, reproducible and appropriate colours, and is most suitable for small batch production. Most commercial plastics are coloured on injection moulding machines, while most engineering plastics are already coloured when sold.

2. The colouring method of colour masterbatch for crate mould processing is divided into a pellet and liquid materials, which can be mixed into various colours. Pellets are the most common among them. The use of colour masterbatch can be realized by mixing plastic with colour masterbatch and actually conveying the mixture or colour masterbatch into an injection moulding machine. Its advantages are cheaper colour, lower dust problem, lower cost of raw materials and convenient storage.

3. The dry toner colouring method for injection moulding is the cheapest, and its disadvantages are dust absorption and dirt during use. To ensure uniform and accurate colour 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 colouring, the surface of plastic particles must be covered with a layer of uniform colouring agent so that the colour can be evenly dispersed in the melt. The method and time of compounding must be standard to ensure uniform colouring. After the colouring step is determined, it must be sustained. In addition, it is also necessary to prevent toner from absorbing moisture during storage, otherwise, it is easy to knot suddenly, causing streaks on the crate mould.

From this, we can see that each of the three methods for processing and colouring crates has its own advantages. We need to select an appropriate colouring method according to our own products so that the processed products can not only meet our requirements but also have the lowest cost and maximize economic benefits.
