The Wrench Torque Testing Machine consists of a loading system, transmission system, digital data acquisition and processing system, and computer-based measurement, control, and display system. It is designed for static torsional mechanical performance testing of various wrenches, including ratchet wrenches, combination wrenches, and open-end wrenches.
The Wrench Torque Testing Machine is mainly used to evaluate the static torsional mechanical performance and torque strength of various hand tools. It is suitable for:
Wrench Manufacturers: Quality control and performance verification of combination wrenches, open-end wrenches, box-end wrenches, and other hand tools.
Ratchet Wrench Testing: Evaluation of maximum torque, torsional strength, and failure torque of ratchet wrenches.
Hand Tool R&D: Material selection, structural design optimization, and product development.
Quality Inspection: Incoming material inspection, production quality control, and finished-product inspection.
Third-Party Testing Laboratories: Mechanical performance testing and product certification.
Research Institutions: Torsional mechanical property research and comparative testing of different tool materials and designs.
