What We Do

MST-X is operating the state of art machinery and equipment designed by the Maruichi’s accumulated knowledge and Japanese engineering. Mother tube produced by MST goes thru the drawing bench to the precision dimension by the hands of highly talented tubing specialists. Then the tubing is cut, degreased, and heated to above 2,000F in Bright Annealing Furnace in order to obtain the scale free smooth shiny surface finish as well as optimum mechanical properties. Tubing then goes thru the same cycle before going to the finishing process of straightening, polishing, final cutting and cleaning to become a product. Finally quality inspectors apply their meticulous eyes to ensure only flawless tubing is delivered to customers.
