what is 2 components molding ?

Since the sixties 2 components / components injection molding, also known as multi-component injection molding is, applied. With 2 c injection moulding technology two materials with different properties, colors or levels of hardness are processed in one or 2 injection molding cycles , without using assembly, into one end product. At 3 k molding this is done this with three different materials. The choice for a multi-component injection molding process is usually based on a cost advantage, design features or esthetic preferences. The techniques at 2 k injection molding are also used in the 3 k injection molding process. That is why 2 k and 3 k injection molding even if plural-component spray casting are discussed. Applications:
What are the benefits of multi-component injection molding? Benefits of multi-component molding compared to single injection molding are: From around 50,000 products this technology can offer a cheaper solution than multi-component molding parts than using single injection molded, followed by assembling. This does depend on product features, such as the product size and choice of materials; A better connection by the chemical or mechanical bond between the different materials, with a good choice of materials, then the los assembling the parts; Gives greater design freedom with different materials in a single product; From an aesthetic point of view it may be more attractive, because the close seams are Delete repeated word: Disadvantages of 2 or multi components injection molding
Process The multi-components molding technology has a great range of different injection molding processes. All these processes can be divided into two main groups: In-mould assembly and In-mould coating. 1. In-mold assembly is joining several different or the same materials in one cycle, with a mechanical binding or a chemical bond. The difference between those two will be explained in the section materials. At In-mould assembly distinction can be made in different processes. |
How we deal with Precision Plastic Injection Molding
To design a mold that is been able to manufacturer high precision injection molded parts is an art or craftsmanship combined with years of engineerign experience , only done by a few injection mold makers . It requires super fine materials, tool making by EDM and cnc machining

When you will get a quote from our company , you will see that our mold cost are lower compared to companies in the West. But sometimes you need to consider additional cost such as transportation to your country, duty tax and so on. IF needed we can quote DDP , meaning Delivery Duty paid, including transportation for your batch from our factory to you door.
