Würth Line China Lab - Würth Industry China

How do you understand quality?

Würth defines it as sensitivity to customer needs. Problems, needs and requirements from our customers are our challenges and the basis of our commitment. Würth has a strong R&D team of 120 people, with a number of utility model and design patents.

The whole product R&D process is based on the opinions of independent institutions, colleges and universities, and customer advisory committee, as well as the customer suggestions with practical guidance. Only when the quality standards are fully met can new products be put into the market.

Large test laboratories of Würth companies worldwide

Würth is Quality

Occupying an area of 800 square meters, Würth China's laboratory is made up of five test rooms and one sample room on two floors. It is equipped with a full range of state-of-the-art fastener testing equipment and 15 testers with eight years of professional experience in average, to provide quality control and customized testing service.

Specialists in connection technology

As innovative pioneers, we respond to requests from all over the world and in doing so, do not shy away from exploring new approaches. We train materials testers year after year, thus securing the technical competence of our team. Except various of dimensional test, our laboratory highlights include the friction coefficient testing machine for connection technology, which can test screws up to size M48. All kinds of hardness test methods and metallographic microscope. Spectrometer and for material analysis and charpy V test.A salt spray chamber is used for corrosion testing. Within Würth Industrie Service, we inspect connection elements for business areas such as goods receipt, initial sample testing, and application consulting and complaints management.

Technology and expertise perfectly combined

Our technical facility is extensive, modern and of a high quality. It is the prerequisite for our wide range of services, oriented to the current and future requests and requirements of our customers.

All Kinds of Tests to Ensure Quality

Dimension Test

In order to ensure the accuracy of thread accuracy testing, all the Go and No-Go Gauges we use are properly stored in Programmable temperature and humidity tester to ensure that they are not affected by the external environment. Because of the equipment above, test results are accurate and reliable. Mahr surface measuring instrument also helps a lot.For applications in some fields, the size needs to be close to "zero defect". The photoelectric screening machine realizes the full inspection of the main dimensions, including cracks and bruises, and effectively avoids the mixing. At the same time we are able to select the products with hardness deviation.

Material Analysis

In order to ensure that our products use the right materials, our laboratory is equipped with a direct reading spectrometer, which can analyze the wavelength of the electric spark light produced by the discharge on the product surface which can accurately determine whether our products contain the required chemical elements and their contents in a short period of time.

Tensile Test

Almost all fastener products define the performance level by their tensile, so tensile test is of course the basic test of fastener products. To this end, we are equipped with several tension testing machines with the capabilities of 10T, 60T, 100T and 200T, respectively, which perfectly cover the finished product specification span from the minimum M3 to the maximum M48. For large size products, the strength can be measured by the method of fine samples. These testing machines have comprehensive functions and can realize various of tensile testing.

Hardness Test

Hardness is one of the core indicators of our materials, and we can test the hardness of all kinds of materials defined in the standard. The laboratory is equipped with Brinell hardness tester, Rockwell hardness tester and Vickers hardness tester. In addition, we also have a micro-Vickers hardness tester to test the hardness changes of the product in different micro areas, and we can determine whether the product has decarburization or carburization.

Impact Test

After the product has achieved sufficient tensile, it needs to have a certain ability to withstand impact at the same time. This is what we commonly call toughness, especially at low temperatures. Our impact test can be carried out far below the standard temperature of minus 20 degrees Celsius to ensure that the product does not cause brittle failure at low temperature. The test also verifies whether its microstructure is 90% martensite as defined by the standard, which is a structure that ensures that it can still withstand impact at low temperatures.

Corrosion Resistance Test

Corrosion Resistance Test are the key to ensure that our products have anticorrosive properties that meet customer requirements. Therefore, our laboratory is equipped with X-ray scanner, eddy current film gaugemeter and other testing equipment. The coating thickness can be measured by gravimetric analysis and metallographic method. The equipment of air heating neutral salt spray experiment are also equipped in this lab. It is placed in a constant temperature and humidity room inside, equipped with a pure water maker and a bucket for salt water.

Torque Test

The torque tester are able to conduct the effective torque test of self-locking nut, the fracture torque test of bolts and screws, the drilling speed test of tail-drilling screws or wall screws, the torque test of adhesive screws and the screw-in ability test of self-extruding screws.

Locking Performance Test

Our laboratory is equipped with a transverse vibration test machine, which uses an automatic Screw tightening device to automatically tighten according to the set torque to start the test. According to the set test parameter conditions, the system will record the changes of each data. Through the data, the locking performance and technical indexes of fasteners in vibration environment can be well analyzed to meet your requirements for locking performance of fasteners.

Friction Test

Friction test is a typical application test. The smaller the dispersion of the friction coefficient is, the more stable the axial clamping force is, the easier it is to calculate the installation torque, and the less likely the screw is to break in the installation process. Our laboratory is equipped with two friction coefficient testers, one can test thread products with nominal diameters from M3 to M24, and the other can measure thread products maximum to M48.

Accreditation certificate

As one of the best equipped laboratories of the Würth Group and the IEC/ISO17025 accredited (established by CNAS and A2LA) laboratory, it provides services for the Group, China and other countries in the Asian Pacific region.
