Rubber compression stress relaxation tester

Machine model: ZB-603Rubber compression stress relaxation tester

One Product Usage

ZB-603 typeRubber compression stress relaxation testerSuitable for measuring the compressive stress relaxation performance of vulcanized rubber, especially for the application research of rubber products as sealing materials. The testing machine has a simple structure and easy operation, with a LCD screen displaying pressure

Shrinkage value, intuitive and reliable, widely used. Meets the requirements of GB1685 "Determination of compressive stress relaxation of vulcanized rubber at room temperature and high temperature".

II Structural function:

1. The testing machine consists of a frame, lifting device, movable plate, fixture (compression device), pressure head, sensor, and digital display control box;

2. Rotate the handle below the testing machine to control the lifting and lowering of the movable plate and fixture;

3. The fixture consists of upper and lower pressure plates, metal rods, insulation sleeves, limiters, fastening screws, and nuts, etc;

4. There are insulation pads between the sensor and the pressure head, and between the fixture and the movable plate, so the fixture is insulated from the entire frame.
