The high quality that SANKYO Manufacturing considers is the philosophy of not allowing defects to flow out to customers. While a system that does not produce or cannot produce defects is naturally essential in manufacturing, human errors can still occur as a fact, beyond those systems, since inspection of each individual item is not always feasible. Reducing the absolute probability of such errors through thorough reasoning and producing rationally is the result of many years of experience. 【Features】 ■ Concept of high quality ■ Proposals that are not limited to cutting processes ■ Rational ideas that are not constrained by technology ■ 30% cost reduction and 50% shortening of delivery times through rationalization *For more details, please download the materials or contact us.
