Zmart is a representative organization of Kistler Remscheid (formerly Schatz) in Germany and AFS Advanced Connection Technology Research Institute in China. It was funded by Zwick China and has a German enterprise background. Its headquarters are located in Shanghai, and it has a joint laboratory for fastening connection technology with Huace Testing in Shanghai.
Friction coefficient testing machine
The quality characteristics of bolts and nuts during installation have a direct impact on the quality of bolted connections. Functional testing is the most important analytical method used in the assembly process. It determines the mechanical characteristics and functions of the fastening parts to ensure their quality. Simultaneously determine the friction coefficient, preload, and torque. And in this process, comply with international standards and simulate usage conditions as realistically as possible.
There are various built-in testing methods that can customize the detection mode according to customer needs.
For the yield point tightening method at the customer's site, our Inspector wrench has automatic recognition of the yield point mode, which can be used to find the yield point through the slope of the torque angle curve. Additionally, our Inspector wrench can set a torque angle window in the program to limit the range of finding the yield point, and can also set the hardness of the connection to better find the bolt yield point!
For some customers' application needs for the return marking point method, our Inspector wrench has a return marking point testing function module, which can be programmed to achieve the return marking point tightening process. This process has many applications in tightening process and torque re inspection!
Multiple complex tightening strategies - torque method, angle method, return mark point method, yield point method.
Equipped with a new generation gyroscope system as standard, there is no need to turn it on and let it sit.
High precision torque acquisition system, with torque accuracy of ± 0.5%.
3.2 inch color display, and can display real-time tightening curves and on-site process point photos.
The scanning unit can be integrated with the wrench.
It can be connected to various types of software to cope with different usage scenarios, and the data and curves can be traced.
Different types of wrench output heads can be customized to adapt to different working conditions.
You can use wireless mode to communicate with the wrench.

Multiple software combinations can better meet the needs of usage
Tailored for the needs of laboratory customer groups, the laboratory analysis software has powerful data curve processing functions and a comprehensive post customized editing mode, which can perfectly complete any analysis task of the experiment!
In response to the tool management requirements of on-site quality customers, Ceus software has a tree like relationship structure system for on-site process points and tools, achieving a combination of on-site tool and quality monitoring management. It can also regularly develop residual torque detection tasks, achieving traceability and visualization of quality management!
For customers with simple and easy to use requirements, we also provide a simple software solution. Q-Lab has simple data upload and program setting functions, catering to simple application needs.
It also has a two channel sensor input port that can be connected to the clamping force sensor and ultrasonic axial force tester, providing a new solution for tightening process engineers to test residual axial force.
You can also input bolt parameters through software to calculate the bolt friction coefficient.
