From June 17th to 19th, the three-day Shanghai Fastener Professional Exhibition came to a successful conclusion, and Shanghai Hengyi Precision Instrument Co., Ltd. provided reliable solutions for fasteners. At the exhibition site, various high-precision testing instruments such as independently developed fastener thread friction coefficient testing machine, nut anti loosening performance testing machine, universal material testing machine, tensile dynamic fatigue testing machine, precision torque wrench, etc. were comprehensively displayed, providing quality assurance for the entire fastener manufacturing process and helping enterprises achieve more efficient and accurate quality control.

The Hengyi Instrument booth has attracted many new and old customers and friends from home and abroad to visit and learn, and our professional technical engineers have provided detailed answers to various questions for them one by one.

Composite microcomputer controlled fastener thread friction coefficient testing machine:

The feature of this machine is the use of a "clamping force thread torque" composite sensor, which is the same as the German equipment and synchronized with the data.

Mainly for testing the thread friction coefficient of fasteners (bolts, nuts, screws, etc.), a dedicated thread friction coefficient testing machine is required. This equipment can accurately measure the total friction coefficient, bearing surface/thread friction coefficient, total torque, bearing surface/thread torque, yield/ultimate torque, yield/ultimate clamping force, torque coefficient, etc. of the threaded pair during the tightening process, to ensure the reliability of fastener assembly and the accuracy of pre tightening force control.

The friction coefficient testing machine for locking nut threads complies with standard references: ISO16047, GB/T 3098.9-2010, GB/T16823.3-2010, ISO 2320, and also meets different vehicle manufacturer standards: DIN946, JISB1084, WZ100, 101, GMW3359, SAE USCAR10, 11, VW01131, etc.

Universal material testing machine: mainly used to test the tensile strength, tensile strength, elongation at break, elastic modulus, yield strength and other related mechanical properties of bolts, screws, metal wires and other materials. It can also perform various mechanical property tests such as compression, bending, shear, peeling, tearing according to different products and materials.

Fastener lateral vibration testing machine: a key equipment specifically designed to evaluate the anti loosening performance of threaded fasteners (bolts, nuts, etc.) under lateral dynamic loads. Its core function is to test the anti loosening ability, pre tightening force attenuation, and fatigue life of fasteners by simulating vibration environments. Implement the horizontal lateral vibration testing standards specified in ISO16130-2015 standard, reference DIN 65151, DIN25201-4, GB/T 10431-2008, and Junker principle.

A precision torque wrench is a tool that precisely controls the tightening force of fasteners such as bolts and nuts by preset torque values.

During the exhibition, Hengyi Instrument further consolidated its cooperative relationship with customers through product displays and technical exchanges, while also establishing contacts with numerous potential customers. Hengyi Instrument provides comprehensive quality control solutions for the fastener industry. Looking ahead to the future, our company will continue to increase research and development investment, deepen technological innovation, collaborate with industry partners for development, and jointly promote the transformation and upgrading of the fastener industry towards high precision and intelligence.
