Plastics Injection Molding Technology

Knauf Industries specializes in innovative solutions for the automotive industry.

Injection molding is one of them – find out what the new plastic injection technology is all about and take advantage of cutting edge solutions for the automotive industry.

How does plastic injection molding work?

Plastic injection molding is an advanced manufacturing process that involves creating parts in specially prepared molds. Injection molding machines enable precise manufacturing of parts for different purposes and with different parameters. Before starting the manufacturing process, Knauf experts focus on a careful preparation of the right mold to avoid production errors at a later stage. As a result, risks associated with potentially failed product prototypes can be reduced. A properly made molding insert makes it possible to obtain the right shape of each component.

Once the right molds for the products are acquired, the actual part of the multi-step plastic injection molding process is carried out. First, the plastic is melted in special barrels; then the plastic is compressed and injected into the previously prepared molds. This way, precisely manufactured components can be created very quickly. This is why rapid injection molding has become so popular in many industries, including the automotive sector.

In automotive, plastic injection molding uses:

  • PC
  • PS
  • ABS
  • PC/ABS
  • PA6 GF30
  • PP GF30
  • PP+T
Plastics Injection Molding Technology

Injection-molded plastics are used to produce, among other things:

  • car bumpers
  • fenders
  • dashboard parts

Automotive plastic injection molding - advantages:

  • possibility to produce parts with different parameters
  • cost-effective production of components in large series
  • production speed
  • delivery of components fully in accordance with customer specifications

Injection molded plastics which are used to prepare modern components for the automotive industry are thermoplastic materials.
Due to this property, it is possible to melt them and inject them into suitable molds. One of the materials used in this technology is liquid silicone rubber, which is characterized by high moldability. In the automotive sector, foamed polypropylene (EPP) and polystyrene (EPS) are widely used – their advantages include a high degree of flexibility and durability combined with low weight.

Why should you choose plastic injection molding technology?

Injection molding services are gaining popularity in the automotive industry primarily because of the quality of the final components. Plastic injection molding enables the delivery of parts that are fully compliant with customer specifications. Knauf experts support original equipment manufacturers, through the entire production process of custom injection molded parts. Custom molding is much faster and more efficient when injection molding technology is applied – which is why it is especially worth considering.

Knauf Injection Molding Services

Knauf Industries manufactures numerous components for the automotive industry using thermoplastic injection molding. The company's experts have extensive knowledge of this process, strengthened also through their work in other industries. This translates into creating high-quality solutions for the automotive sector as well. Knauf Industries offers a full range of services related to the process of plastic injection molding. You should also remember that the plastic injection molding machine is not the only tool used during manufacturing – the technological process begins well before the plastic goes into the mold.

Knauf offer includes, for example:

  • full process simulation (FS, DFM, Mold Flows) on the basis of a computer model - the company's experts use the newest, state-of-the-art specialized software which streamlines the creation of models. One of the programs used here is the Moldflow, which allows to simulate the flow of the material in the mold during the manufacturing of parts – it allows the experts to optimize the design of the molds, as well as the subsequent manufacturing process;
  • reversing engineering,
  • testing and preparing reports,
  • development of tools and coordination of their implementation,
  • coordination of texturing.

Additional services by Knauf Industries

Plastic injection molding and preparation for these processes is a key part of Knauf's services, but the company's support also covers other stages of production. Additional operations such as the assembly of sound-absorbing parts, clips and clasps are also carried out. Knauf also offers decoration of plastic parts in cooperation with an external company - an industrial paint shop - that provides paintwork for aesthetic details.

Among the techniques offered are:

  • screen printing,
  • pad printing,
  • high gloss,
  • metallization and PVD.

The plastic injection molding service has become a flagship activity for the Knauf Industries factory in Wroclaw.
