![[Case Study on Production Equipment] Gasket Replacement Work](https://image.mono.ipros.com/public/product/image/406/2000643542/IPROS18395826049933901602.jpeg?w=280&h=280)
Special gasket damaged? We can produce it urgently! We also carry out replacement work to contribute to the early restoration of the production line.
In a case at a pharmaceutical company, a filter-integrated gasket incorporated into a rubber-lined tank was damaged, causing expensive resin material to leak outside the tank, which required urgent response. Considering the dissatisfaction with the airtightness, we proposed a review of the structure and a redesign for production. As a result, we were able to complete the replacement work for the affected tower in about a month after the consultation. Not only did we shorten the delivery time, but our safety management system for the construction was also appreciated, leading to the request for the replacement work of all remaining towers. [Case Study] ■ Issues - The filter had a tear, causing expensive resin material to continue leaking outside the tank, resulting in daily losses. ■ Proposal - Considering the dissatisfaction with the airtightness, we reviewed the structure and proposed a redesign for production. *For more details, please refer to the PDF document or feel free to contact us.
