Overview
Automotive components have to survive millions of load cycles and demanding operating conditions. From suspension and shock absorber springs to high-strength bolts and fasteners, and from chassis steels to rubber seals, every part must be qualified for fatigue life, mechanical strength, hardness and joint integrity before it goes into a vehicle.
CHENJI supplies the material and component testing machines that automotive manufacturers, tier suppliers and testing laboratories rely on — spring fatigue and torsion testers, shock absorber test benches, bolt and fastener analysis systems, universal tensile and hardness testers, and impact testing machines. Every machine is designed, processed and assembled in-house with strict quality control and factory-direct pricing.

Spring & Suspension Testing
TPJ-20 Mechanical Dynamic Spring Fatigue Testing Machine — A touchscreen-controlled fatigue tester for helical springs and cylindrical shock absorbers on automobiles, motorcycles and other motor vehicles. It offers a maximum test force of 20,000 N (20 kN) with two simultaneous test stations (10,000 N per station), a test frequency of 1-5 Hz and a maximum stroke of 100 mm. A force sensor monitors spring force in real time and stops the machine automatically when force attenuates below the set value. View details

Bolt & Fastener Testing
M10-M20 Bolt Friction Coefficient Tester (NCMC-2000SE) — A microcomputer-controlled fully automatic thread analysis and testing system for testing axial force (clamping force), total torque, preload, thread torque, support surface torque, total friction coefficient, support surface friction coefficient, thread friction coefficient and K coefficient. All test data are recognized by metrology agencies, testing agencies and bolt manufacturers. View details
M12-M36 Computerized High-Strength Bolt Torque Coefficient Tester — For high-strength bolt torque coefficient and friction coefficient testing across M12 to M36, plus the ISO 16047 torsion strength machine covering 1000-2000 N·m. View details
Material Testing for Automotive Metals
Universal Tensile Testing (up to 1000 kN) — The WDW-100 (100 kN) electronic and WAW-1000A (1000 kN) hydraulic universal testers measure tensile strength, yield strength, elongation and elastic modulus for automotive steels and chassis materials, supporting GB, ISO, JIS, ASTM and DIN standards.
Hardness testing — Vickers (HVS-1000), Brinell (HB-3000C) and Rockwell hardness testers qualify heat-treated and surface-hardened automotive parts.
Impact testing — The JB-W300/500/YZ low-temperature automatic impact tester and 300-750 L instrumented impact machines test toughness of automotive steels at standard and low temperatures.
Frequently Asked Questions
Which machine tests automotive suspension and shock absorber springs?
The TPJ-20 (up to 20 kN) performs fatigue testing of helical springs and cylindrical shock absorbers, while the mechanical-type fatigue tester covers 10 kN to 30 kN. For telescopic shock absorbers themselves, the TPJ-W10 test bench runs dynamic and static fatigue, damping and friction tests with a maximum speed of 1.04 m/s.
Can you test automotive fasteners and bolted joints?
Yes. The NCMC-2000SE thread analysis system (M10-M20) measures axial force, total torque, preload, friction coefficients and K coefficient, and the M12-M36 computerized tester covers high-strength bolts. The ISO 16047 torsion strength machine handles 1000-2000 N·m for torque/clamp-force relationships.
How do you test tensile strength of automotive steel?
Use an electronic or hydraulic universal testing machine. For small coupons the WDW-100 (100 kN) works well, while high-strength chassis steels and larger specimens suit the WAW-1000A (1000 kN). Both measure tensile strength, yield strength, elongation and elastic modulus to GB, ISO, JIS, ASTM and DIN standards.
Do you support hardness and impact testing for automotive parts?
Yes. Vickers, Brinell and Rockwell hardness testers cover heat-treated and surface-hardened parts, and the JB-W low-temperature automatic impact tester plus 300-750 L instrumented impact machines evaluate the impact toughness of automotive steels.
Are these machines used by automotive manufacturers?
Yes. They are used by automotive OEMs, tier suppliers and testing laboratories to qualify suspension springs, shock absorbers, fasteners, chassis metals and rubber seals before production and in incoming-material inspection.
