Main Structure, Function and Application Range ：WDW series are suitable for tensile, compression, bending , cutting shearing and tearing test of rubber, peeling and tearing, plastic, electrical wire and cable, composite, profiled bar, waterproof roll, etc. They are essential testing instruments for quality testing section, university and college, research institution and industrial and mining enterprise.
This machine equips alternating servo motor for driving crossbeam and imported photoelectric encoder for displacement measure. The controller adopts flush type monolithic computer structure and is equipped multitask operating system and built-in powerful test control software, which includes the test system with measuring, controlling, calculating and saving functions.

This machine has the following performances: Automatically calculating stress, elongation rate, tensile strength and modulus of elasticity；automatically preserving all of 16 groups testing data；automatically recording the value of extremal vertex, breakpoint, appointed value of force and elongation；testing result can be scanned by pages and printed；the third class purview management；real-time electronic clock, and automatically recording the testing date and time.
