Customer-specific tool designs: High-tech and know-how for your tools

Do you want to manufacture injection-molded parts made of plastic and require a competent partner for the design of the corresponding tools? Or would you like to optimise and further develop an existing preliminary design? LANGER offers top quality and all-round service in the design and manufacture of custom injection molds. We develop injection-molding tools among other things for the following applications:
  • Injection-compression molding 
  • MuCell® / chemical foaming 
  • Fusible core injection molding 
  • Internal gas-assisted injection molding 
  • Water-injection molding
  • Extrusion blow molding / plastic housing 
  • Assembly injection molding 
  • Two-component injection molding 
  • Molding around inserts
During the design of plastic injection-molding tools, we draw on 49 years’ experience gained during our company's history. We offer CAD part and tool design on the basis of CATIA as well as CAM programming (NGC CAM solution). We ensure the consistently high quality of our products using, among other methods, computer tomography, laser scanning as well as optical and tactile measurement, and we can also offer a reverse engineering service. We deliver to customers all around the world and pay heed to a resource-conserving and sustainable way of working during mold construction.

3D tool design for every industry and every requirement

We assume responsibility for the complete planning and design of your injection-molding tools. Tell us what your injection-molding tools are required for and which properties they should have. If you already have a draft design, we would be happy to help with its further optimisation. We offer CAD part and tool design on the basis of CATIA as well as CAM programming (NGC CAM solution). Our service portfolio also includes the optimisation of your component data to suit the tool.

Numerous satisfied customers bear witness to our high degree of customer orientation. Among others, we receive orders for plastic-injection molds from customers in the automotive, construction, medical technology, mechanical engineering and aerospace sectors.  From consultancy to quality control, you receive all services from a single source. In the process, the communication via EDI enables simple and flexible data exchange with our customers.
Customers in the following fields also profit from our high quality standards:
Plastic injection molding
Cubing model construction
Inspection tool and gauge manufacturing
Renewable energy
