Brief Introduction:This machine is a testing instrument specially designed for sofa spring frames and spring packs. It can meet the following three testing requirements:
1. Durability test: Repeated pressing tests can be conducted under pre-set pressure conditions. The cycle can be preset and the test will automatically stop when the set number is reached.
2. Detection of the relationship between compression range and pressure: Press down according to the preset stroke and stop when the position is reached. Read the spring force of this stroke on the pressure gauge, and display the stroke value on the screen.
3. Spring compression detection under specific pressure: The pressure plate is pressed down to the set pressure and then stops. The display screen shows the compression stroke length of this pressure value.
