Unlike the traditional probe and laser measurement system, ECM uses visible light imaging technology. First, the measured object is projected and then analyzed according to a number of projection data. After the analysis, the size, shape and position of the product can be automatically obtained, which are related to bolts and revolving bodies.

The friction coefficient control of bolts and nuts in assembly process has an important influence on the quality of bolted connections. The friction coefficient tester ensures the stability and high quality of bolt assembly by analyzing the friction coefficient.

The simulation assembly system can be used to study the actual assembly performance of fasteners under actual assembly conditions.

In order to achieve reliable bolting in modern industrial processes, reliable tightening of the gun is essential. Not only must the tightening gun be calibrated and certified prior to assembly, but it must also be tested repeatedly during assembly. The goal is to ensure continuous high performance in order to achieve optimal assembly results and meet established standards.

Ultrasonic bolt axial force measurement system is a simplified bolt axial force control tool. By measuring the actual tightening bolts with the calibration bolts and ultrasonic waves, a clamping force of up to ±3% accuracy can be obtained. Away from the torque method, the clamping force is greatly different, which is your preferred engineering solution.

Whether it's a sample inspection during the process or a continuous inspection of the tightening gun and torque wrench, accurate and rapid access to measurement data is key to improving product quality and optimizing the process. Our compact inspection system uses state-of-the-art hardware and software to continuously acquire and display torque and corner measurement data. Users benefit: judge the quality of parts that have been produced to identify potential weaknesses and challenges early in the production process.

The quality characteristics of the bolts and nuts during installation have a direct impact on the quality of the bolted connections. Functional testing is the most important analytical method used in the assembly process. It determines the mechanical properties and functions of the fastening parts to ensure their quality. Also determine the coefficient of friction, preload and torque. In the process, we comply with international standards and simulate the conditions of use as realistically as possible.

Comfort test system can quantitatively test the comfort of door, trunk, seat, engine hatch, shift rod, glove box, sunshade, steering force, switch button, pedal and a series of "human-vehicle interaction" parts to ensure the realization of the best ergonomics.
