[Proposal Example] Change of Supplier for Existing Products

Cost reduction of approximately 7.0 yen per unit, saving 3.5 million yen per year with an annual production of 500,000 units, contributing to stable supply of parts!

We would like to introduce a case that our company proposed. With the increase in demand for water-related components (check valves), production volume is transitioning from 15,000 units per month to 30,000 units per month. However, there was a challenge of supply shortages due to insufficient production capacity. Therefore, we proposed a method of sourcing stainless steel valve-type products that have been manufactured by another company for the past ten years and assembling them in-house. By changing the sourced products to those from an automotive parts manufacturing company, we improved quality and reduced costs. Additionally, we created a simple assembly machine to enable in-house assembly. As a result, we achieved a cost reduction of approximately 7.0 yen per unit, saving 500,000 units annually, which amounts to a reduction of 3.5 million yen per year, contributing to a stable supply of components. *For more details, please refer to the PDF document or feel free to contact us.

Check valve

Yuai, a specialty store for piping materials and equipment by professionals in filling machines.

It is widely used in sanitary piping to prevent backflow of fluids. It is also called a check valve or backflow prevention valve, and is installed in piping to prevent backflow of fluids such as water. When the pump starts, the valve opens due to the pressure of the flowing fluid, and when it stops, it naturally closes due to the pressure of the fluid trying to flow back.
