The process of double color injection molding is a very strict process. If you want to make a good mold, you must strictly control the process of injection molding. In particular, it is necessary to understand the precautions of injection molding of the two-color mold, so as to better avoid some unnecessary problems in the process of injection molding of the two-color mold. So what should we pay attention to in injection molding of two-color molds? Let's share it with you.

First, when choosing the mold, do not only look at the price, but also analyze and consider the quality, cycle, service and other aspects.

There are many kinds of two-color molds on the market. When choosing, different types of molds should be selected according to different requirements of parts materials, dimensional accuracy, surface finish, physical and chemical properties, mechanical strength, service life and so on.

The precision of the two-color mold needs to use high precision CNC machine tool processing, and the mold material, forming process have strict requirements, but also need to use CAD/CAE/CAM mold technology to design and analysis.

Some parts due to the molding of special requirements, mold also need to use hot runner, gas assisted molding. Manufacturers should have CNC, EDM, linear cutting machine tools and CNC copying milling equipment, high-precision grinding machine, high-precision CMM, computer design and related software, etc.

Secondly, some customers in product development or trial production of new products, in the early stage often only focus on product development, ignore some communication between the two-color mold manufacturer. In fact, after the product design scheme is preliminary determined, there are two advantages to contact the mold manufacturer in advance.

On the one hand can ensure that the design of the product has a good forming process, will not be difficult to process parts and modify the design.

On the other hand, two-color mold makers can make design preparations in advance to prevent careless consideration in a hurry and affect the construction period. In a word, the production of high quality mold, only supply and demand both sides closely cooperate, in order to reduce the cost, shorten the cycle.

Finally, because the two-color mold or semi-finished product needs to be rotated, mold design and injection molding machine requirements are more precise. As the high variability of the injection molding of the two-color mold,  to achieve smooth production and meet the expected ideal, all the mold design must be considered synchronously with the product design.

The above is some notes of the injection molding of the two-color mold, We hope to help you in the injection molding of the two-color mold.
