Effort reduced, quality improved

Shaanxi Hangyu Non-ferrous Metal Processing Co., Ltd. is a supplier of precision parts for the aerospace and chemical industries. Its precision products are mainly made of titanium and titanium alloys. The WENZEL XO series coordinate measuring machines help Shaanxi Hangyu improve the performance, quality and reliability of its products.

Hangyu manufactures hydraulic valve bodies, for example. The requirements for the accuracies of size, shape and position tolerances are extremely high. Before using coordinate measuring machines (CMMs) from WENZEL , measurements were performed by an external service provider. However, the quality managers were dissatisfied with the time efficiency and process management.

In the second step, about 70 different measuring machines were purchased, but this resulted in large deviations. For example, there were too many different specifications for three-point internal micrometers and the measurement accuracies could not be readily guaranteed.

The products manufactured in different industries vary in complexity and sophistication, as do the measurement and control tasks. Documenting and optimizing the quality of the manufacturing process to minimize waste, improve product quality and reduce costs are therefore necessary.

Ultimately, it was CMM solutions from WENZEL that provided Hangyu with the measurement solutions they were looking for. Aimin Dong, Executive General Manager at Hangyu, explains, "We mainly use the CMMs from WENZEL to solve the measurement problems of geometric tolerance and high-precision dimensional tolerance. These technical requirements are very important to us. For example, in various complex valve bodies, there are very high requirements for roundness, dimensional tolerance, shape and position of the main function hole. At the same time, positioning accuracy must be guaranteed within 0.008 mm. The CMM solution from WENZEL performs well on all these points and supports us greatly in quality assurance."

As a supplier to the aerospace industry, Hangyu has very strict requirements for product quality and is extremely careful when selecting measuring equipment. When asked why Hangyu chose WENZEL , Aimin Dong says, "Before purchasing the coordinate measuring machines, we compared four companies based on the following criteria: First, the vendor's service; second, the quick response to our detailed inquiries; and third, we visited users and gathered application information about the CMMs."

"We chose WENZEL based on two considerations: First, WENZEL has a number of use cases in the Baoji area and enjoys a good reputation; second, the active cooperation of team members and the performance of machines from WENZEL encouraged us to make the right decision. Hangyu has grown from a small company with only 5 devices to a large enterprise with nearly 200 devices and a production area of 48 hectares after more than ten years. WENZEL has helped us a lot with its CMM solutions to improve the quality of our products and save us the cost of buying other measuring machines ."

Impressive service concept

The all-round service concept of WENZEL rounded off the offer, which Mr. Dong confirms with satisfaction: "The after-sales staff of WENZEL are very conscientious. They can help us with any question by phone, WeChat, video or on site. In addition, the CMMs are used very frequently because we use the double hundred percent inspection system and a large number of precision machined parts need to be measured. For many years, I have been very satisfied with the accuracy of the CMMs from WENZEL . We have confidence in the brand WENZEL."
