Injection Moulding
In this process, networked information and materials are combined. The idea becomes a product.

Here it is decided that everything was done correctly. Here it is decided whether all the parameters previously defined properly and in the optimal combination have been coordinated. And indeed, with the effect that product quality, productivity and process reliability are assured of the highest sustainable level.

This effect is achieved at b-plastic with the best possible coordinated production systems, through highly qualified staff and a high degree of automation. Thus, e.g. moulding technique and injection moulding systems are combined in such way that maximum efficiency is achieved at the injection moulding process.

All injection units of different size and configuration are networked to a central PDA and PPS system and are controlled by these systems. A fully automated material handling system ensures the production process for exactly the right amount of plastic granules, which requires the respective injection molding machine for their current production order. The production is performed in a two-or three-shift system.


One form of further processing at b-plastic is the assembly of semi-finished products made ​​of plastic, metal and other materials. The assembly process and the degree of automation are based on the final product and the production volume.

To ensure the best possible flexibility in the assembly technology and to be able to realize and use additional potential the assembly machines are be developed, designed and manufactured in-house from the beginning on. All automatic units are equipped with advanced control and process technology.
This method also enables us to react more flexibly to customer requests; e.g. if it is required to modify  products from our standard range.
