Chuanbai WDW-20/20KN Tensile Tester Universal Testing Machine for Polymers

WDW-20 Microcomputer-controlled electronic tensile testing machine is mainly used for testing mechanical properties of various metals, non-metals and composite materials such as tensile, compression, bending, shear, stripping, tearing, etc. The system adopts microcomputer closed-loop control, which can realize constant velocity displacement, constant velocity stress, constant velocity strain and can be programmed. The design of the test machine has the characteristics of beautiful appearance, convenient operation, stable and reliable performance, no pollution, low noise, and high efficiency. The design of the auxiliary equipment is matched with the main machine. The structure is wedge-type translational and manual rotary clamping. The specimen is not subject to additional force. Convenient, reliable and non - slip clamping.

The working environment should be free from vibration and dust. At room temperature (15-25); Humidity < 70%; Surrounding no vibration, no corrosive medium, no strong magnetic field interference; Power supply voltage fluctuation not exceeding 10% of rated voltage.

This machine is widely used in such  mechanical property tests of tensile, compression, bending, peeling, tearing, shearing, puncture, adhesive strength in metal and non-metallic materials, such as in steel, spring, plastic, rubber, fabric, ropes, belts, man-made board, paper, building materials, composite materials, waterproof materials, packaging materials, medical supplies etc.

Grips Specification:
