DOUBLE INJECTION MOLDING / TWO SHOT INJECTION (2K)

Double Injection, sometimes known as 2 material 2 shot molding or 2K molding, is an innovative manufacturing process used to produce complicated molded parts from two different materials. Through a highly specialized and automated process we carefully control the injection of multiple materials, including two different kinds of resin, into a single, multi-chambered mold.To get more news about 2k injection moulding, you can visit asm-mold.com official website.

Double Injection in performed on one machine that is programmed to perform two injections in one cycle. In the first cycle, a nozzle injects plastic into a mold. The mold is then automatically rotated and a different type of plastic is injected into the mold from a second nozzle.
Double Injection Molding optimizes co-polymerization of hard and soft materials to create powerful molecular bond. The result is a single part with production and feature advantages. It can be used for a variety of product designs across all industries. It also allows for molding using clear plastics, colored graphics and stylish finishes which improves your product functionality and marketplace value.
In general, the process is fairly similar to conventional (single material) injection molding. The materials are brought to their melting point and then fill the mold cavities.

Bi-injection uses a press equipped with a second screw and hopper to inject the complementary material at the same time. The definition of the parting line is generally validated during the part analysis phase.

In single-material injection, resin is injected into a cavity and then, after an appropriate cooling time, the two mold halves are opened, and the part is ejected. In biomaterial molding, the two resins are injected into the mold. For this purpose, a space must be created in the mold to accommodate the additional resin. To do this, several bi-injection methods for tooling are available: transfer molds, molds with rotatory plate, molding with a rotating base, molding with core-back process.

Depending on the properties of the part and the project constraints, our team of designers and engineers is responsible for determining the most suitable solution for you from among these different tools.
