injection moulding
Progressive injection moulding is the further development of the known reel-to-reel process. It combines two production steps in a single machine: the processing of the stamped strip and partial overmoulding up to the finished component
Progressive injection moulding was developed by the Kummer GmbH company approx. 20 years ago. Today this process stands for high process reliability, increased economy and higher quality. This is based on the power of innovation and over 40 years of production experience.
The core idea of progressive injection moulding is to use the clamping force of the injection moulding machine to also carry out forming processes. The result is a fully automated production process which enables the forming process at almost no additional cost.
In the progressive injection moulding process, the following working steps are combined in a closed process:
- the mechanical processing of the lead frame,
- which is fed via an automated process (stamping, bending, etc.),
- and complete or partial overmoulding with plastic
The component is therefore stamped, bent and overmoulded in a closed process. Optical and electromechanical sensors integrated in the machine continuously monitor the process and quality of the component.

Innovative technology results in process reliability
The core idea of progressive injection moulding is to use the clamping force of the injection moulding machine to also carry out forming processes. The result is a fully automated production process which enables the forming process at almost no additional cost.
Innovative technology results in process reliability
The advantage of progressive injection moulding is that it only requires a single tool for the complete process. The result is that tool changeover times and machine downtimes are considerably reduced. Furthermore, the machine can be universally used. Therefore, the machine can be set up for a different product simply by changing the tool. This serves to reduce the costs per part.
