​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.
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.
Double Injection advantages include:

• Lower unit cost
• Improved part integrity
• Multi-material efficiency
• Higher-quality plastic part fabrication
• Reduced handling and secondary assembly
• Reduces cost and waste associated with assembly defects
• Enhanced tactile and cosmetic product feature

Sheet matal can also be ovemolded by plastic. It is usual application on metal plastic combined nature in general application.

Each individual set of unscrewing assembly is designed.
