The engineering foundation of YOMURA TECHNOLOGIES began long before the company existed. President Liu started his career designing machinery to build automobile engine parts and later textile machines in the 1960s. He was then employed as the plastic tooling engineer for Philco-Ford.(a joint partnership company in Taiwan that manufactured TVs, radios, ). In 1970 he decided to venture out on his own and founded his first company manufacturing hydraulic pumps and assemblies. Soon after his hard work paid off with his design and patent of the first hydraulic lift gate for Taiwan delivery trucks. This was a huge success.
In 1974, he decided to diversify and created a second company, Yonkers Inc., specifically for injection molding. It was at this company that he built his first complete injection mold machine. Having made a name for himself earlier in the knitting machine industry, he was able to win important sewing machine parts contracts from Singer.
In 1979 Leon traveled to Germany to purchase a high-end, Arburg double injection mold machine. It was the first and only one of its kind in Taiwan. Because of the quality of the machine and his expertise in material properties, he was able to win important contracts from Olivetti, a major typewriter company, making double injected key caps. This machine would later make key caps for Apple's first keyboards. In 1989 Leon re-organized Yonkers as renamed the company Yomura.
Since then, YOMURA TECHNOLOGIES has gone on to design, manufacture and assemble millions of plastic components for a wide variety of industries including 3C, aerospace, automotive, healthcare, military and many others.
