Reduced effort, improved quality

Shaanxi Hangyu Non-ferrous Metal Processing Co., Ltd. is a supplier of precision parts for the aerospace and chemical industries. The 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 accuracy requirements for size, shape and position tolerances are extremely high. Before WENZEL coordinate measuring machines (CMMs) were used, the measurements were carried out by an external service provider. However, quality managers were dissatisfied with time efficiency and process management.

In the second step, around 70 different measuring devices were purchased, but this led to major discrepancies. For example, there were too many different specifications for three-point internal micrometers and the measurement accuracies could not be easily guaranteed.

The products manufactured in various industries vary in complexity and complexity, as do the measurement and control tasks. It is therefore necessary to document and optimize the quality of the manufacturing process to minimize waste, improve product quality and reduce costs.

After all, it was WENZEL's CMG solutions that provided Hangyu with the required measurement solutions. Aimin Dong, Executive General Manager at Hangyu, explains: “We use WENZEL's KMGs primarily to solve the measurement problems of geometric tolerance and high-precision dimensional tolerance. These technical requirements are very important to us. For example, various complex valve bodies have very high requirements for roundness, dimensional tolerance, shape and position of the main functional hole. At the same time, positioning accuracy must be ensured within 0.008 mm. The WENZEL CMM solution performs well in all of these areas and provides us with great support in quality assurance.”

As a supplier to the aerospace industry, Hangyu has very strict product quality requirements and is extremely careful when choosing measurement equipment. When asked why Hangyu chose WENZEL, Aimin Dong says: “Before buying the cooperative measuring machines, we compared four companies based on the following criteria: First, the provider's service, secondly, the quick response to our detailed inquiries and thirdly, we visited the users and collected application information about the KMGs.”

“We chose WENZEL based on two considerations: First, WENZEL has a number of use cases in the Baoji area and has a good reputation; secondly, the active cooperation of team members and the performance of WENZEL's devices have encouraged us to make the right decision. After more than ten years, Hangyu has grown from a small company with only 5 devices to a large company with almost 200 devices and a production area of 48 hectares. With its CMG solutions, WENZEL has helped us a lot to improve the quality of our products and save us the costs of buying other measuring devices.”

Impressive service concept

WENZEL's all-round service concept rounded off the offer, which Mr. Dong confirms with satisfaction: “WENZEL's after-sales staff is very dutiful. You can help us with any question by phone, WeChat, video, or on site. In addition, CMMs are used very frequently because we use the double hundred percent inspection system and a large number of precision-machined parts have to be measured. I have been very satisfied with the accuracy of WENZEL's CMMs for many years. We trust the WENZEL brand.”
