Wakabayashi Seiki Kogyo was founded in 1957. Starting as a tool trading company, it introduced general-purpose lathes in 1965 and entered the machining industry. With the introduction of NC (numerical control) lathes in 1979, it fully dedicated itself to machining.
"While our business has primarily focused on resin molding and other processing, we also handle non-ferrous metals. We specialize in small to medium-volume manufacturing and possess the technical capabilities to respond to customer requests and product development. We also maintain thorough quality control and aim for a defect rate of 0.%, consistently producing and supplying high-quality products. For the past 10 years, we have strategically targeted the medical and testing equipment market, aiming to contribute to "Made in Japan" medical equipment and instruments."

They have established an integrated system from injection molding to precision machining. In particular, for molding irregular shapes, maintaining quality is difficult with injection molding alone, and machining is unavoidable. Generally, machining is done as an add-on, but this company designs molds with precision machining as the premise and takes on the work all by itself, pursuing high quality and precision. This is a skill that can only be achieved with an integrated system.
This also offers significant benefits to the customers. They can obtain reliable products simply by placing an order, leading to increased efficiency and enabling them to pursue new initiatives. "This division of roles creates a win-win relationship and enhances the value of both companies," the president emphasizes.

The company's motto is to tackle even the most challenging requests from clients. Except for cases that are physically impossible, they take the stance of working together with the client to find a solution. President Wakabayashi's belief that "if you end up losing money by taking on a project, it's because you lack the necessary skills" is deeply ingrained in the workplace. While profitability is important, the company prioritizes realizing clients' requests and tackles difficult problems every day.
This way of thinking has led to improvements in technological development capabilities and transformations in manufacturing processes, while also fostering employee confidence and growth, accumulating as an "invisible asset." This asset will undoubtedly be a powerful tool for realizing product development aimed at new fields.
