2-component or multi-component injection molding is a special process in injection molding technology.
The special feature is that two plastic melts are injected simultaneously or successively into a mold. This process is available in a large number of variants, each of which is tailored to the desired results (products).
The process variants we use result in certain technical possibilities and associated advantages:
Multiple functions in one component
In injection molding, different plastics are often combined to form a solid unit in order to combine various functions in one component. The advantage lies in the reduction in the number of components and simpler assembly. In addition, injection molding assembly can avoid costly processes for subsequent machining such as welding, bonding or vulcanization.
Examples:
- Bearing, anti-burglary device and gap cover for front doors in one component.
- Differential pressure adjustment and multiple sealing functions in a single component for sanitary or fluid engineering applications
Two-color design and viewing window
Two plastics of different colors can be joined together to form a multicolored, solid unit. This makes it possible to achieve multicolored component surfaces, lettering in contrasting colors, logos, additional design elements or windows without subsequent operations such as printing or hot stamping.
Different surface properties
By combining two plastics, firmly bonded components with different surface properties can be produced. In this way, a special feel and impression of the components can be created. Assembly in one injection molding process saves additional haptic elements and further operations such as gluing or assembly.
