The client is a well-known pump manufacturer that both produces and sells pumps. They needed to carry out quality inspections on pump impellers. To meet market demands and boost their competitiveness, the client decided to ditch traditional inspection methods and adopt new measurement techniques. They specifically invited our company for a product demonstration to quickly and accurately get detailed 3D inspection results, check if the products meet standards, and improve product quality and development efficiency.

Actual picture of water pump impeller on site

        1. The water pump impeller is small in size and has dark black and metallic reflective surfaces in parts of its surface, making it more difficult to scan. The product is prone to deformation during the production process, so the quality control of the water pump impeller is particularly important, and customers require very high precision.

        2. Simply using traditional detection methods (such as inspection tools, jigs, three-dimensional coordinates, etc.) is difficult and time-consuming. The process is cumbersome and time-consuming, and it is not easy to accurately and quickly measure structures such as the curvature of the water pump surface. detection.

Water pump impeller scanning site picture

    The water pump impeller is small in size and has a large curvature on the impeller surface. The surface of the impeller is dark black and has a metallic reflective surface, making it difficult to scan. The customer requires fast scanning speed and very high accuracy. Our peers use traditional detection methods for measurement, which not only requires spraying of developer , and the scanning speed is slow, the workflow is complex, and it takes a long time to scan the workpiece. Many dimensions and shape features cannot be effectively measured, which easily produces secondary errors and affects the production quality and production efficiency of the product.

     In response to the problems faced by customers, HOLON 3D technical engineers used thehandheld 3D scanner Model 37 to quickly and accurately obtain the 3D data of the impeller. The scanning is convenient and quick without spraying developer, and the scanning speed is fast and the measurement accuracy is high. Successfully solved the problems faced by customers.
