Our quality  control


We have three septs for the quality control :


1.   We will use 100 degrees Celsius boiling water for preliminary welding inspection. 


2.   We will use helium to suppress the float for more than 8 hours to test the degree of pressure resistance of the float. 


3.   Our testing equipment is a helium mass spectrometer. It is the first in China to use this equipment to detect floats, so that the floats that our factory goes out are 100% leak-free. In addition, after the factory quality inspection, we will also carry out The final test, mainly to check whether the appearance of the product is uneven, to ensure that each products appearance is fine, without any flaws, to ensure that the customer receives the perfect product.
