Physical drawing of equipment:

Physical drawing of 20t needle punched extrusion testing machine

2. Standards met by needle pressing test: for example, GB / T 31485-2015

3. Acupuncture extrusion system upgrade:

The standard clearly stipulates that the extrusion speed is 5 ± 1 mm / S. in the experiment, the speed should be kept unchanged during the extrusion process to reach the set conditions. Our company uses German servo drive system, Beckhoff weighing sensor module, Beckhoff ek1100 and el9011 to read the signal of pressure sensor. In cooperation with the front-end pressure sensor of extrusion, the full closed-loop control realizes "pressure displacement speed acquisition frequency 20ms", which meets the test requirements, and solves the problem of "in the process of extrusion, the extrusion speed does not meet the experimental conditions" The test data of "reduced pain point" are as follows:
