2K is well known as 2 shot injection molding, 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 who has manufactured parts using the 2K injection process for more than 20 years. 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. 2K injection component technology is also ideal for parts with large batches.
2K injection , sometimes know as double injection or 2 shot molding, is an innovative manufacturing process used to produce complicated molded parts from two different materials into multi-chambered mold.
2K injection 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 mold is then rotate automatically and another type of plastic is injected from a second nozzle into the mold.
2 shot injection optimizes co-polymerization of hard and soft materials to create perfect bond with production and feature advantages for a single part. Almost all industries can use it for a variety of product designs. It also allows for molding using clear plastics, colored graphics and stylish finishes which improves customer's product functionality and marketplace
No secondary processing and assembly steps
Excellent adhesion to the plastic part
Quick cycle times
High degree of automation
Stable production processes
Premium has advanced machines that take 2K injection molding/two Component injection molding.
This 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 completely 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 double injection.
