Two component 2K injection molding of handle switches

Two-color injection molding of handle switches is an injection molding process used to manufacture handle switches and other products. handle switches:

Process principle: Two-color injection molding of the handle switch is to use two different colors of plastic materials during the injection molding process and inject them into the same mold to achieve the two-color effect of the handle switch. Injection molding is usually performed using a vertical injection machine or a rotary injection machine.

Mold design: Two-color injection molding of the handle switch requires the design of a suitable two-color injection mold. The mold usually consists of two injection cavities and an indexing mechanism, which are used to inject two different colors of plastic materials respectively.

Material selection: Two-color injection molding of the handle switch requires the selection of two different colors of plastic materials. These materials are generally compatible to ensure good fusion and bonding during the injection molding process.

  • Two component 2K injection molding of handle switches
    Injection molding process: The injection molding process of two-color injection molding of handle switch includes the following steps:
    a. Inject the first color plastic material into one of the injection cavities of the mold.
    b. The indexing mechanism rotates the mold so that the plastic material of the first color is filled into part of the mold.
    c. Inject the second color plastic material into another injection cavity of the mold.
    d. The indexing mechanism rotates again to fill the second color plastic material into another part of the mold.
    e. After the plastic material cools and solidifies, take out the handle switch two-color injection molded product.
    Post-processing: Two-color injection molded products of handle switches may require post-processing, such as burr removal, edge trimming, etc., to improve the appearance quality of the product.
