Product requirements are strict：

Internal:test raw material of stainless steel and wax;

repair WAX ,if the wax mold is unqualified, the cluster process will not be assembled.\4

Before pouring, spectrum analysis will be carried out

After passivation, the first casting inspection will be carried out. If it is unqualified, it will be returned for treatment.

We have three inspection teams when processing CNC lathes, namely, workers' self inspection, patrol inspection and final inspection before leaving the factory. Even, some products will be leak tested.

Due to so carefully to quality,we win more and more returned customers.

External:Passed ISO,BV, PED,AD2000,UKCA,accept any 3rd party inspection before shipment.
