Result
A hybrid of an injection molded part with metal insert and mechanical post-processing – a masterpiece. During an intensive co-engineering process with the customer, the bending and torsional rigidity were fully optimized. The alignment of the metal insert is controlled by a special technology in the injection mold. The repeat accuracy is in the range of a few angular seconds. This is the only way to ensure the necessary precision for the subsequent mechanical process. Markings on the product are applied both through spraying and using lasers. The subsequent machining of the glass-reinforced polymer requires the parts to be aligned with an accuracy of 1/100 mm. Article-specific clamping and sophisticated measurement systems support our specialists in their work. Only the use of milling algorithms and coordinated tools developed in-house guarantee process reliability for thousands of parts. We achieve a very high degree of automation due to robot support. A final blasting process with dry ice removes any parting line burrs while also cleaning the part – everything from a single source.
