Every valve is manufactured with AMO SOP


raw material

Raw Material Preparing


AMO only accept the high quality brass & EPDM rubber that pass the AMO internal standard tests
•Confirmation of product design & specs
•Tensile test
•Rigidity test
•Surface quality test


Metalworking


All the AMO metalwork according to the principles as bellow
•Cut the raw materials into pieces according to product dimensions by auto cutting machine
•Drill, Chamfer & Thread by the semi-automation meter lathe
•Clean up the stem covered with oil by ultrasonic cleaners

Rubber Mixing


Rubber mixing is the most important step among the whole processes which determine the reliability of the valve. AMO family develop & adopt exclusive formula to strengthen the valve performance
•High tensile force
•Excellent surface gloss
•Outstanding adhesive performance


Vulcanization


Combine metal with rubber in imported vulcanizing machine though accuracy control the temperature & time, we can get the satisfying overall valve.
