2k Injection Molding
2K is well known as 2 shot injection molding or two colour injection moulding, consists of two different plastics or two different colors of one plastics into an end product by means of one injection molding process.
Premium is an industrial machining inc that has manufactured parts using the 2K injection moulding process for more than 20 years. The 2k injection molding process enables several functions to be integrated into an injection molded part. Due to the chemical bond between the different materials, excellent adhesion is achieved, without the thermoplastic part requiring chemical pre-treatment. two colour/ 2K injection moulding component technology is also ideal for parts with large batches.
How Does 2K Injection MoldingWork?
2k moulding, sometimes know as double injection, two color injection molding, or 2 shot molding, is an innovative manufacturing process used to produce complicated molded parts from two different materials into the multi-chambered mold.
2K injection moulding perform in one machine which is programmed to perform two injections in one cycle. In the first cycle, a nozzle injects plastic into a mold. The 2k plastic injection mouldingis then rotated automatically and another type of plastic is injected from a second nozzle into the mold.
Two color injection moldingoptimizes co-polymerization of hard and soft materials to create a perfect bond with production and feature advantages for a single part. Almost all industries can use two colour injection mouldingfor a variety of product designs. The 2k injection also allows for moulding using clear plastics, colored graphics, and stylish finishes which improves customer's product functionality and marketplace value.
Advantages Of 2K Injection Molding
No secondary processing and assembly steps
Excellent adhesion to the plastic part
Low handling
Quick cycle times
High degree of automation
Stable production processes
Economical cost
As one of the professional injection mold components suppliers, Premium has advanced machines that take 2K injection molding/two colour injection moulding.
The 2k injection moulding allows us to integrate multiple properties into one product: for instance, layered products, combinations of hard and soft plastic for making different color combinations.
The technology 2K injection molding makes it possible to produce a complete product so that this part does not need further secondary processing and assembly steps. That means gains in the quick cycle time, a constant process, a higher degree of efficiency and the avoidance of manual operation, you can save cost also save considerably on costs with two colour injection moulding.

Two Color Injection Molding Technology Processes
Two Color Injection Molding Technology Types
The two color injection molding technology has three types according to the structure classification. They are core rotation, core retreat, push plate rotation.
Two Color Injection Molding Technology Features
First of all, the two color injection molding technology needs to match the injection molding machine. 2k mould has more than a rotating mechanism or up and down sliding mechanism.
Secondly, there is a difference in the 2k injection moulding former model, and then the core is consistent. Two color injection molding technology should pay attention to the application of cylinder or other power.
Finally, the precision of the two colour injection moulding technology is high.
Two Color Injection Molding Technology Design Features
The two shapes of the mother mold are different, forming one product respectively. While the two shapes of the male mold are exactly the same.
The front and back of the two color injection molding products must match after rotating 180°to the center.
