Product Overview

Our production of a variety of rubber vacuum diaphragm is suitable for automobile manufacturing, aerospace, petrochemical machinery, industrial and mining metallurgy, pipeline valve, automated meter high-tech electronics and other industries supporting capacity.

Product Performance: excellent gas tightness, resistance to flexion, anti-ozone, low temperature flexibility is good. The thickness is only 0.5mm, under the circustances of  test exercise frequency 300 ± 10/min, it still can flex at 120,000 times without cracking under normal atmospheric. It with long service life.

Breakthrough of quality and workmanship:

1. For the widespread concern diaphragm leak problem on the market today, our company for special studies, The diaphragm which we produced can ensure a complete non-disclosure or a weak leak. Can provide a better valve life. 
2. The pulse valve products our company manufactured now can completely replace imported products. 
3. Shore hardness is between 65-80, customers also can customize. 
4. To ensure product cloth patch is located in the middle of diaphragm, the surface smooth, flat,no cracks,bubbles and other defects. 
5. Diaphragm at an ambient temperature of -20 to 237 ℃, the working pressure is 0.8MPa, the working life are no less than 100 million times.
