The WDW-50A microcomputer controlled electronic universal testing machine is mainly used for testing mechanical performance indicators such as tension, compression, bending, shear, peeling, and tearing of various metal, non-metal, and composite materials. The system adopts microcomputer closed-loop control, which has a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity in measuring and controlling loads and displacements. This equipment is suitable for manufacturing industries such as metals, adhesives, pipes, profiles, aerospace, petrochemicals, waterproofing membranes, wires and cables, textiles, fibers, rubber, ceramics, food, pharmaceutical packaging, geotextiles, films, wood, paper, as well as product quality supervision departments at all levels. It is also suitable for teaching demonstrations in colleges and universities.
The design of the testing machine host has the characteristics of beautiful appearance, easy operation, stable and reliable performance, no pollution, low noise, and high efficiency. The design of the auxiliary equipment is matched with the host, with a wedge-shaped translational structure and manual rotation clamping, and the sample is not subjected to additional force. Convenient, reliable, and non slip clamping.
