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

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 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

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

We have high-end auto core & cap assembly machines, Making the valve cores & caps assembly more accurate, guaranteeing the normal torque value in all parts of the valve.

All finished valves will be inspected by experienced workers according to our line to ensure all the function satisfying your order.

We will then package the valves carefully in designated packaging to prevent them from shocking during delivery.
