2-component injection moulding is a special process in injection moulding techn­ology.

2K injection moulding (two-component injection moulding) is a manu­facturing process that enables the simultan­eous injection of two materials (multi-components) in a single process. This process is mainly used in the plastics processing industry.

In 2K injection moulding, two different plastics are injected simultan­eously into one mould. The main advantage of this process is the ability to produce parts from different materials and/or colours in a single operation. This saves time and costs and increases production efficiency.


Flexible in use

The applications of 2K injection moulding are diverse and range from the production of complex parts for the automotive industry to medical devices. These processes can also be used to produce products with improved mechanical properties, longer service life and enhanced aesthetics.


Advantages in material and design

The combination of different materials in 2K injection moulding enables innovative designs and improved properties. For example, depending on the plastic selected, a soft component can offer an improved grip or a hard component can contribute to increasing the structural integrity of the product.


Advantages of 2K injection moulding


Although the 2K injection moulding process is complex and technically demanding, it offers many advantages, including high product quality, product consis­tency and produc­tivity. In addition, it enables high design flexibility and can be used to manufa­cture products with complex shapes and structures.

  • process enables the production of multi-component parts in a single production cycle, saving time and costs.
  • The use of multiple materials in one mould enables the production of complex parts without additional assembly.
  • By using these processes, product safety and functi­onality can be improved as different materials with different properties can be used.
  • It offers the possibility to improve product aesthetics and haptics by using different colours and textures in a single produ­ction process.

Tool­making in 2K injection moulding

When building a mould for 2K injection moulding, it is important to consider the design, functi­onality and the plastic selected for the products to be produced. The moulds must be manu­factured and adjusted with particular precision to ensure the quality of the end products. The choice of material is also crucial as it affects the durability and perfor­mance of the product.

The develop­ment and construction of moulds for 2K injection moulding requires a high level of technical expertise and experience. The moulds must be designed to meet the specific require­ments of the part to be produced.


Testing and quality assurance in 2K injection moulding

In the aerospace industry, the focus is on optimising performance and efficiency.

Testing and quality assurance in 2K injection moulding is an important part of the production process. The aim here is to ensure that the parts produced meet the specified quality standards.

This process begins with the design of the parts and continues throughout the entire production phase. Various inspection methods are used to ensure the quality of the products. These include visual inspections and measurements.

Visual inspections are carried out to detect obvious visual defects such as cracks, deformations or colour deviations. Measurements are carried out to ensure that the parts correspond to the specified dimensions.

In addition to these inspection methods, the machines and tools used in 2K injection moulding also play an important role in quality assurance. Both the injection moulding machine and the injection moulding tools must be regularly maintained and checked to ensure that they function properly and produce high-quality parts
