Always Several Steps Ahead

Every year, around 1.5 billion components are produced on the injection molding machines at Scholz. The injection-molded tools required for manufacturing these parts are created in the company's own mold making process by approximately 40 highly skilled employees. Since 2009, they have achieved micrometer precision, i.e. 0.001 millimeters. The company's designers have helped make this possible. When undertaking complicated corrections to the injection-molding tools in the past, the designers had to manually transfer the deviations between the scan data of the first manufactured parts and the CAD data to Excel files to evaluate them – a very time-consuming and error-prone process. Performing five or more correction loops was not unheard of at Scholz GmbH for extremely complicated parts.

ZEISS Reverse Engineering software processes unstructured 3D point clouds, and it makes no difference if the data were obtained using contact measuring machines, computer tomographs, laser scanners or optoelectronic systems. The software then uses the point clouds to detect the underlying geometries. Thanks to the algorithms developed by ZEISS for surface reconstruction, the software is particularly well-suited for companies like Scholz GmbH that want to convert their highly precise measurement data into an exact CAD model. There is another factor that makes the ZEISS software so useful for Röder, an engineer in the Design department at Scholz, and his colleagues: "Currently, there is no software for reverse engineering that features specially integrated functions for tool manufacture."
