During the design of two-component injection-molding tools, we draw on 49 years’ experience gained during our company's history. We ensure the consistently high quality of our products using computer tomography, laser scanning as well as optical and tactile measurement, among other methods. We deliver to customers all around the world and pay heed to a resource-conserving and sustainable way of working during mold construction.

Two-component tools: This is why customers rely on injection molds from LANGER

In two-component injection molding, parts are manufactured out of two types of plastic. The plastics used can differ either with regard to colour or also with regard to the material properties. Two-component injection molding enables complex parts to be manufactured in a single step and is thus an exceedingly flexible and economical method.

We at LANGER specialise in the manufacture of precision two-component injection-molding tools. From simple to highly complex molds, we provide you with custom tools in wide-ranging sizes. Our competencies also include the manufacture and assembly of component groups. Our high-quality two-component injection-molding tools allow for cost-saving and reliable manufacturing of multi-component parts in all industrial sectors.

Types of multi-component manufacturing at a glance

Today, it is impossible to imagine modern industry without two-component injection-molding tools. Use our high-quality multi-component tools and profit from the wide range of possible applications offered by this manufacturing process.
  • Colour combinations: Multi-component tools are a particularly efficient way of implementing ambitious colour schemes. Instead of dying or painting the parts during a second step, the material used already possesses the desired colouration. That gives the parts an elegant and high-quality appearance and is also a very cost-saving method of manufacturing coloured components.
  • Material combinations: Two-component injection molding enables two different materials to be combined. This results in numerous ways to realise certain component properties or functions. Caps, sports glasses and electrical appliances are just a few examples for typical applications in industry.
  • Assembly injection molding: Using multi-component injection molding, component groups with parts that can move against each other are manufactured. These parts can possess, for example, joint and hinge functions. Injection molding and assembly thus become a single step, which results in a significant time saving, especially when producing large quantities.
Depending on the requirements, the two plastics used can have a clear separation or run into each other. To produce a clear separation, an unfinished part is produced in a first step and then subsequently overmolded. If the raw materials are to run into each other, the components are injected before the first one has solidified.
