What is injection molding technology?

Injection technology

Injection molding is one of the most established technologies for producing plastic components. It is a process in which plastic granulate is melted and then injected under pressure into a special mold. The prepared material then hardens, resulting in a product – so-called molded part – with a defined shape and parameters.

At Knauf Industries, we ensure the highest quality of service delivery and manufacturing process 

We guarantee the support of our engineering team and a comprehensive approach to the production of plastic parts. We offer professional technological advice and efficient implementation of the injection molding process.

Polystyrene is highly used in construction in a broad range of applications. The most highlighted ones are undoubtedly in terms of insulation, namely panel applications and HVAC systems components; and related to backfilling, as due to its lightness it enables to reduce the weight of embankments, especially on top of soft soil

Post-production services after the injection molding process

In addition to the injection molding process, the post-production services that Knauf Industries offers to all its customers are also important, guaranteeing faster lead times and a shorter supply chain. These include:

  • component assembly
  • ultrasonic welding
  • production and processing of plastic parts
  • quality control
  • packaging
  • preparation of parts for dispatch.

One stop shop. More than standard

Thanks to over 20 years of experience, a modern technology park and the implementation of additional services in the one-stop-shop concept, we ensure the highest quality of services and production of injected components.

A modern production facility Knauf Industries plastic parts are made in our production plant in Wrocław (Nowa Wieś Wrocławska). The base of the injection molding machine park is a set of modern machines, including over 20 injection molding machines, with a clamping force from 80 T to as much as 2000 T. Presses equipped with SEPRO manipulators are additionally supported by 6-axis ABB robots that perfectly cope with more complex operations such as e.g. cutting of injected parts, gradation and flame cutting.
