Quality Inspection Center

Our enterprise technology center is located in Anhui Province. It is home to a full range of advanced test facilities as well as a group of experienced quality engineers and operators. We have built long-term partnerships with Xi’an Jiaotong University and Hefei University of Technology.

The tensile testing machine is used to measure the elongation of finished products.

The tensile testing machine is working on a test specimen.

Data will be obtained as the machine continues to pull on the specimen until it breaks.

Seen here is the physical property testing laboratory. A wide collection of lab facilities is available for conducting a full range of tests on our metal castings. A variety of hardness testers is utilized to meet various customers’ product hardness requirements. The impact testing machine is used to determine the anti-impact capability of different materials.

Shore hardness tester from Japan’s NSS Company

This equipment is used to check the anti-impact capability of our products.

Direct-reading digital Brinell hardness tester

Demonstrated here is the molding sand property testing lab. This lab performs qualitative and quantitative analysis on the viscosity, particle size, apparent porosity and hardness of the molding sand.

Sandcast mold sample

The constant-temperature furnace is used to examine the sintering performance of the sand cast mold sample.
