Silicone And Rubber

Two-color silicone rubber automotive products.,engineered or house hold components, compression or transfer molds, Plastic or Rubber.Two-color injection molding refers to the injection molding of two different materials into the same set of molds, so as to achieve the injection molded parts formed by two materials. Some of the two materials are different colors, some are soft and hard, so as to improve the beauty of the product and assembly and other performance. characteristic: 1. The two shapes of the female die are different, forming a product respectively, and the two shapes of the male die are exactly the same. 2. After the front and back dies of the mold are rotated 180° to the center, they must be consistent. This inspection action must be done during the design, which requires higher requirements for the positioning and processing of the die frame. 3. The total thickness of the front die panel plus A plate shall not be less than 170mm. Please carefully review other reference data for this model of injection molding machine, such as maximum mold thickness, minimum mold thickness, KO hole distance, etc. 4. The water mouth of the three-plate mold is best designed to automatically release the mold. Pay special attention to whether the release action of the soft glue mouth can *. 5, in the design of the second injection mold, in order to avoid the second mold insert (or wipe) damage to the first time has been molded product glue, you can design a part of the avoidance. However, we must carefully consider the strength of each sealing position, that is, in the injection molding, whether there will be deformation of the plastic under large injection molding pressure, resulting in the possibility of batch front generation of the second injection molding 6. When injection molding, the product size of the first injection molding can be slightly larger, so that it can be pressed more tightly with another male mold during the second molding to achieve the role of sealant. 7. Pay attention to whether the flow of plastic in the second injection molding will impulse the first already formed product, causing its colloidality deformation? If this is possible, be sure to find ways to improve. 8. Before closing the mold of A and B plates, pay attention to whether the front mold slider or inclined top will reset first and crush the product? In this way, it is necessary to find A way to close the mold in A and B plates first, and then the slider or inclined top of the front mold can be reset.
