Optical injection moldingHighest Precision Shot by Shot
Injection molding of high-precision polymer optics
The production of polymer optics by injection molding is based on a complex interaction between man, machine, material and mold. Technology and experience are essential for a stable injection molding process. This already starts with the granulate. High-grade raw materials of optical quality, dehumidification, dust removal, a particle-free environment and the right temperature during the melting process are of particular importance. In combination with this, the perfect control of all machine and process parameters, the use of modern injection molding machines that are pure in terms of type, and our high-precision injection molds lead to results with the highest homogeneity and clarity. In this way, we are also able to meet particularly high cleanliness requirements. In addition, our self-developed and continuously optimized processes for cleaning the injection units, 3D handling and robot systems, and modular automation solutions guarantee maximum manufacturing flexibility.

Optical metrology close to production
In the injection molding of polymer optical components, the molding process also has a significant influence on the part geometry, which in turn is decisive for the correct optical function of the component. Accordingly, uncompromising adherence to the tightest tolerances is essential. During the entire production process, our experienced setters and process mechanics monitor all relevant parameters in addition to our test engineers in order to be able to react to deviations as quickly as possible - depending on the requirements, this is done within the scope of 100% tests, by means of statistical process control (SPC) and not infrequently by means of functional testing on customer-specific test benches. In projects with very high quantities, solutions for 100% inspection by automated test systems are also available in addition to inspections by our highly qualified team. In this way, components are produced shot for shot with the highest precision.
