General information

Short Summary
A German university has developed an economic micro-component injection molding process for all batch sizes. The injection molding unit concept allows greatly reduced dwell times, low energy consumption, and very good reproducibility. The university offers a lisence agreement.
Full Description
Economic micro-component injection molding (for all batch sizes) is no longer a pipe dream. A German university Köln has developed a polymer laboratory in which it has discovered how to economically melt and inject thermoplastics not only in multiple cavities, but also with single-cavity molds. The injection molding unit concept allows greatly reduced dwell times, low energy consumption, and very good reproducibility.

This is accomplished with a new type of shut-off needle integration into the injection piston and clever plastic melt guidance. Injection unit volume is so low that short dwell times can be achieved in single-cavity molds even without oversized gating systems. The unit can be combined with sprueless injection molds. Dwell time was reduced by more than 90%. Material flow is FIFO (First In – First Out).

The university offers a licensing agreement to companies in the plastics industry.
