Optimized quality assurance in mold making

Die Finke Group, an established mold making company specializing in injection molding manufacturing, has successfully integrated an LH 1512 coordinate measuring machine from WENZEL into its manufacturing processes. The measurement solution has made a significant contribution to ensuring the manufacturing quality and dimensional accuracy of their products.

The Finke Group manufactures a wide range of parts that are used in various end products. The parts manufactured include injection molding tools, gauges, removal grippers, and assembly devices. These are used for a wide range of applications, from individual tools to complex GID articles as well as cube tools in the embossing process. The size of the tools ranges up to 2,800 × 1,500 mm with a total weight of 30 tons.

By using the WENZEL measuring system, in particular the LH 1512 coordinate measuring machine, the Finke Group can precisely check the quality of its tools and articles. This enables accurate measurement in accordance with the required specifications and effective support when tool changes are made. The component measurement is used to verify the specification, to determine distortions and to carry out series-related measurements during plastics production.

The main task is to ensure the dimensional accuracy of the plastic articles produced. This includes measurements for initial sample test reports, measurements during production and ensuring machining. Before the WENZEL measurement system was introduced, a joint measuring arm was used. However, this was no longer accepted by customers due to its inadequate accuracy. The required measurement accuracies are based on the specific requirements of customers with regard to SPC measurement tests (“Statistical Process Control”). The WENZEL CMG (coordinate measuring machine) provides the required accuracy to meet these requirements.

The Finke Group uses the WENZEL-KMG LH 1512 in combination with a PH 10M Plus rotary swivel head and a tactile SP25M probe system from Renishaw. For optical measurement, the highly flexible WENZEL SHAPETRACER 3D line scanner is used to capture and process point clouds in order to effectively complete the measurement tasks.

This multi-sensor solution provides a wide coverage of measurement requirements with high accuracy in accordance with specifications. The measurement systems are located in a specially equipped measurement room near the production plant. This enables measurements to be carried out efficiently and promptly during the manufacturing process. ”

WENZEL measurement systems were selected based on various criteria, including coverage of a wide range of applications with high accuracy, cost-benefit ratio, machine availability and user-friendly and ergonomic operability,” explains Nick Nolte, measurement technician and quality advance planner at the Finke Group.

“We also particularly appreciate WENZEL's outstanding customer service and availability as well as the solution-oriented cooperation. The ability to rely on a reliable contact person in case of problems is of great value,” continues Nolte. The successful implementation of WENZEL measurement systems has enabled the Finke Group to optimize its manufacturing processes and further improve the quality of its products. The partnership with WENZEL underlines the commitment of both companies to technical excellence and customer satisfaction.

Since 1982, Finke has stood for absolute quality and the highest level of performance in mold making. Originally started as a glass mold manufacturer, since the 90s we have developed into a powerful manufacturer of injection and die casting molds for the plastics industry. In 2012, we expanded our range of services to include the area of “application technology” and specialized in the sampling of injection molding tools and the production of plastic injection parts. Our goal was and is to move our customers forward with creative ideas, qualified know-how and passionate enthusiasm for technical innovations. No matter how the years come and go, our mission remains the same: We want to help our customers reach the top of the podium.
