Production processes in plastic injection moulding technology

Both automatic and manual production methods are used in modern plastic injection moulding technology. Both methods have their own advantages and applications, which we would like to explain in more detail here.

Automatic production processes

make our processes more efficient and precise. The use of state-of-the-art technologies and machines minimises errors and increases production speed.

Advantages:

  • Higher productivity and accuracy
  • Lower costs thanks to optimised use of resources
  • Fast throughput times
  • Reduced downtime thanks to automated maintenance systems

The integration of Industry 4.0 technologies enables real-time monitoring of production processes, leading to continuous improvement.

Surface technologies

Textile / IMD / IMF / IMTR / IMDS: These processes enable us to integrate textiles or films directly into the injection moulding process, resulting in unique surfaces and functionalities.

Manual production processes

rely on the skill and experience of our employees. These methods are particularly valuable when it comes to complex or customised products where precision and attention to detail are crucial.

Advantages:

  • Flexibility in adapting to special customer requirements
  • Possibility to realise prototypes or small series
  • High quality thanks to human sensitivity

Although manual processes are generally more time-consuming, they often offer invaluable benefits in areas where creativity and customisation are required.

Manual production processes

Welding technologies

Various welding technologies play a central role in plastics processing. Here are some of our most important processes:

Ultrasonic welding (US)

Ultrasonic welding uses high-frequency sound waves to join plastics. The heat generated melts the material surfaces, creating a strong bond.

Advantages:

  • Fast processing
  • No additives required
  • High precision and repeat accuracy

Vibration welding

Vibration welding

In vibration welding, the parts are joined together using mechanical vibrations. This method is particularly effective for larger surfaces and complex geometries.

Advantages:

  • Strong joints
  • Suitable for thicker materials
  • High production speed

Laser welding

Laser welding uses a focussed laser beam to join plastics. This technology enables precise weld seams and is ideal for sensitive materials.

Advantages:

  • Minimal thermal stress
  • High flexibility in design
  • Excellent surface quality

Hot plate welding

Hot plate welding

In hot plate welding, the parts to be joined are heated on a heated plate until they melt before they are pressed together.

Advantages:

  • Ideal for large areas
  • Stable connections
  • Easy handling
