Optimized quality assurance in mould making

The Finke Group, an established company in the mould making sector specializing in injection moulding production, has successfully integrated an LH 1512 coordinate measuring machine from WENZEL into its production processes. The measuring solution has made a significant contribution to ensuring the production 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 produced include injection molding tools, measuring gauges, removal grippers and assembly devices. These are used for a wide range of applications, from single tools to complex GID items and compression molds. The size of the tools ranges up to dimensions of 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 precise measurement in accordance with the required specifications and effective support for tool changes. The component measurement is used to verify the specification, to determine distortion and to carry out series-accompanying measurements during plastics production.

The main task is to ensure the dimensional accuracy of the plastic items produced. This includes measurements for initial sample test reports, measurements during series production and ensuring machining production. Before the introduction of the WENZEL measuring system, an articulated measuring arm was used. However, this was no longer accepted by customers due to its insufficient accuracy. The required measuring accuracies are based on the specific requirements of the customers with regard to SPC (Statistical Process Control) dimensional checks. The WENZEL-CMM (coordinate measuring machine) offers the necessary accuracy to meet these requirements.

The Finke Group uses the WENZEL-CMM 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 3D line scanner WENZEL SHAPETRACER is used to capture and process point clouds in order to manage the measurement tasks effectively.

This multi-sensor solution offers broad coverage of measurement requirements with high accuracy according to specifications. The measuring systems are housed in a specially equipped measuring room close to the production area. This enables measurements to be carried out efficiently and promptly during the production process."

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

"We also particularly appreciate the outstanding customer support and availability provided by WENZEL as well as the solution-oriented cooperation. Being able to fall back on a reliable contact person in the event of problems is of great value," continues Nolte. The successful implementation of the WENZEL measuring systems has enabled the Finke Group to optimize its manufacturing processes and further increase the quality of its products. The partnership with WENZEL underlines both companies' commitment to technical excellence and customer satisfaction.

Since 1982, Finke has stood for absolute quality and top performance in mold making. Originally started as a glass mold manufacturer, we have developed into a high-performance manufacturer of injection and die-casting molds for the plastics industry since the 1990s. In 2012, we expanded our range of services to include "application technology" and specialized in the sampling of injection moulds and the production of plastic injection moulded parts. Our goal was and is to help our customers move forward with creative ideas, qualified expertise and passionate enthusiasm for technical innovations. No matter how the years come and go - our aspiration remains the same: we want to help our customers reach the winner's podium.
