Differential Analysis of Two-color mould and Rubber-coated m

There are two different kinds of plastics in the products made by two-color mould and glue-coated mould. But there are many differences in their plastic mold technology, mold difficulty and product price.

The two-color mold is a kind of advanced injection mold, which is produced by a special two-color injection molding machine. There are two nozzles on the injection moulding machine which can directly inject two different kinds of plastics. Now there are some extended products on the market, such as tricolor. Its two colors of plastic injection moulding is on the same pair of plastic moulds. When injection moulding, it is produced by rotating the back of the plastic moulds. In this way, the upper and lower moulds of plastic moulds are avoided, the products can be directly formed, the uniformity and accuracy of product location are guaranteed, and the qualified rate of products is very high.

As an extension of the ordinary injection mold, the encapsulation mold often needs to open two moulds for a product. It is necessary to put the product from the first plastic mold into another one, and then inject it to form a product at the same time. Because it is two different injection moulding processes. As a result, products tend to have a high scrap rate.

In terms of production time, the two-color die can realize automatic production, and the output of the product is relatively high. The plastic wrapping die is a product that needs manual injection for the first time, and the production efficiency is low. In terms of product quality, the two-color die is often the market of high-end products, while the glue-coated die is mostly low-end products, and the use of products is relatively low. For the cost of plastics, the cost of two-color mold is often several times that of the plastic-coated mold. It is also because of the low cost of plastic wrapping dies, often in large plastic molds and products with low output, the preferential choice of plastic wrapping dies.

The two-color mold of glue-coated mould can be customized. According to their own needs, customers who want to open two-color molds are welcome to call for consultation!
