What our customers say
Switching a part from casting to forging eliminated porosity ("su") and stabilized quality.
When we could not draw a forging-ready part drawing, Ogawa Tekko redrew and proposed one for us.
Their forgings machine more easily than other suppliers — feedback we hear from several customers.
