This is a line for manufacturing the outer tub of a washing machine, consisting of four main press processes, bending, riveting, and six riveting processes.
Customer's Request We want to significantly shorten the production lead time by utilizing painted steel sheets. We aim to streamline production by eliminating work-in-progress items and reducing costs. We desire a line that can produce necessary items when needed. Additionally, we want to prevent environmental pollution in the atmosphere and water quality and significantly improve the workplace environment. Reason for Choosing Enami Seiki Due to the small space that fits into a low-ceiling assembly factory (about 3m), a pit for pressing is not necessary. They have a wealth of experience in the pressing of painted steel sheets. Development Goals By adopting PCM steel sheets, we aim to establish a method of joining components using riveting as an alternative to welding, while also achieving a scratch-free processing (pressing) of the outer frame appearance. Additionally, we aim to realize a no-changeover production line by only exchanging molds for two models with different curvatures that have a fully rounded shape. Results (Customer Feedback) We were able to reduce manufacturing costs by 20% before and after using painted steel sheets.
