[Case Study] Investigation and Manufacturing of Special Screws from a Factory that Went Out of Business and Became Unknown

From detailed investigation to product manufacturing, we offer one-stop support! Our strength lies in the ability to calculate setting values immediately.

We would like to introduce a case where we proposed the clarification of details for special screws, which became unclear due to the closure of a factory, using knowledge of drawing production and inspection tools in the plant maintenance industry. During the maintenance of a rod mill, the screws used became unavailable, making maintenance impossible. After our proposal, we were able to manufacture screws identical to the samples by selecting a manufacturing method according to the size and shape of the screws. [Overview of the Issue] - The factory that was commissioned to manufacture the special-shaped screws went out of business, resulting in the unavailability of screws needed for maintenance of the rod mill. - The only remaining item was a sample of the screw, which provided information only about its shape and material, as well as rough dimensions. - Three sizes of screws were needed in the quantities listed below by the maintenance scheduled to start in four months, and without these screws, maintenance of the rod mill could not be performed. *For more details, please refer to the related links or feel free to contact us.*
