Color mold: two on the same plastic material injection molding machine, a two-molding, but the product only once a die mold. In general this is also called double injection molding process is usually done by a mold, and the need for specialized color injection molding machine. Color mold growing popularity on the market today, in this process can make the appearance of the product is more beautiful, easy to change colors and you can not spray, but expensive, technically demanding.
1 is a master of two different shapes, namely one kind of molded products, and the male mold the same as the two shapes.
Before 2. mold after mold in the center of the rotation 180o, must be consistent. This inspection must be done design movement, this points to a higher mold positioning processing requirements.
The total thickness of 3 plus front panel analog A panel of not less than 170mm. Please carefully review this model other reference data injection molding machines, for example, the maximum capacity of the mold thickness, the minimum thickness tolerance mode, KO-hole distance.
4 three plate mold outlet preferably designed to automatically release action. Pay particular attention to whether the action of soft release outlet can be *.
5 In the design of the second master mold injection, in order to avoid secondary master mold insert (or rub) injury for the first time have a good product molding plastic bits, you can avoid the empty part of the design. However, the intensity must be carefully considered every sealed plastic bits, namely: in injection molding, whether there will be a big injection under pressure, plastic deformation occurs, resulting in a second injection may be approved front possible?
6. injection molding, injection molding products for the first time can be slightly larger size to make it in the second molding with another male molded tightly to achieve the effect of sealing glue.
7 Note that in the second injection, the plastic flow of whether the impulse for the first time has been forming a good product to glue bit deformed? If there is a possibility, must find ways to improve.
8 before the A, B plate mold, pay attention to whether the former mode slider or lifter will be reset and crushed product? So, we must find ways to make the A, B board first mold, mold slide before or after the lifter to reset.
9 two master mold and mold public water transport arrangement as fully as possible, and the balance, the same.
10.99% of the cases are injection molded hard plastic part of the product first, and then injection molded soft part of the product. Because soft and easy deformation.
