Yonglida WDW-20 electronic multi-function testing machine has beautiful appearance, easy operation and stable and reliable performance. It is suitable for testing the mechanical properties of various metals, non-metals and various composite materials. It is widely used in construction and building materials, aerospace, machine manufacturing, wire and cable, rubber plastics, textiles, home appliances and other industries. It is an ideal choice for scientific research institutions, colleges and universities. It is a satisfactory testing equipment for colleges, industrial and mining enterprises , technical supervision, and commodity inspection and arbitration departments.

Using programmable device CPLD. High-speed processing, program-controlled amplification, stable and reliable. The control performance has three closed-loop control methods of force, displacement, and deformation, and real-time data display. It also has test curves such as force-displacement, force-deformation, and force-time. After the test is completed , the upper and lower elasticity of the elastic quantity can be automatically calculated. Test results such as strength, technical strength, elongation, etc. have built-in test methods for metals or non-metals such as GB/28-200, diversified report formats, and standard database management methods. The machine uses an AC servo speed regulating motor and a cross-link servo speed regulating system as the driving device. After being decelerated by the arc synchronous belt and arc synchronous pulley deceleration system , it drives the precision screw pair for loading. It has smooth transmission, low noise and high operating efficiency. And it has the characteristics of high precision, wide speed range, stability and reliability. It has multiple protection functions such as peak hold, automatic shutdown when specimen breaks, electrical overload, upper and lower mechanical limits, etc. Complete tensile, bending, compression, shear and other tests according to corresponding standards.
