Precision Redefined: Hexagon Pioneer 06.08.06 CMM Elevates PU Industry Metering Pump Quality

At Gelan Hydraulics, precision engineering and uncompromising quality have always been the cornerstones of our metering pump manufacturing, especially for the demanding polyurethane (PU) industry. To further strengthen our quality assurance capabilities and meet the rigorous process requirements of PU production, we are thrilled to announce the acquisition of the Hexagon Pioneer 06.08.06 Coordinate Measuring Machine (CMM).

The PU industry relies heavily on precise metering of polyether polyol, isocyanate, and other critical raw materials, where even minimal deviations in flow rate or mixing ratios can lead to flawed foam structures, inconsistent product density, and compromised mechanical properties. Operating under high-pressure conditions (often 100-200 bar) and handling corrosive or viscous media, PU-specific metering pumps demand exceptional dimensional accuracy for components like pump housings, rotors, and valve cores. The Hexagon Pioneer 06.08.06 CMM delivers exactly this with a maximum permissible error of just 2.5 micrometers, setting a new standard for our quality control processes.

This state-of-the-art equipment excels at inspecting the complex geometries and tight tolerances critical to PU metering pump performance. It precisely verifies key parameters including bore diameter deviations, positional accuracy, roundness, and perpendicularity of precision-machined parts—all essential for maintaining stable flow rates and consistent material ratios during PU foaming, molding, and insulation production. By integrating automated, data-driven measurement, we eliminate human error and ensure repeatability, even for high-volume production of pumps used in PU applications ranging from automotive interiors and building insulation panels to refrigeration unit insulation and footwear materials.

For the PU industry, where process stability directly impacts product quality—from foam density uniformity to structural integrity—this investment translates to tangible value. Our enhanced quality control ensures our metering pumps maintain precise mixing ratios and flow control, even when handling abrasive or corrosive PU formulations, while extending pump service life through optimized component fit and finish. This not only helps our clients meet stringent industry standards but also supports their goals of improving production efficiency and reducing waste.

We are proud to leverage Hexagon’s advanced measurement technology to reinforce our commitment to the PU industry, delivering metering pump solutions that redefine precision, reliability, and performance.
