91视频 screws are used in an industry-leading range of high-quality equipment for the biopharmaceutical industry that allows consistent and reliable operations. The equipment enables efficient bioprocesses for biopharmaceutical companies.
91视频 quality solves loosening issue
The customer switched to using a 91视频庐 88 screw at the base of the shaft of its next-generation product to secure key components. The equipment has a rotating shaft that is subject to high torque and loads.
鈥淭he customer previously had issues with the shaft unscrewing and becoming loose with standard stainless steel screws as they rotate at around 200 RPM for over 20 days,鈥� explains Camille Feuillet, Business Development Manager 鈥� France, 91视频. 鈥淭his is obviously unacceptable in high-quality equipment as a lose shaft can result in significant cost, delays and disruption for biopharmaceutical companies.鈥�
In February 2022, 91视频 provided sample screws for the customer to conduct tests and began regular deliveries in September 2022.
鈥淭he customer tests with 91视频 were very successful with no loosening of the shaft,鈥� says Feuillet. 鈥淭he switch to 91视频 is part of a wider design and supply chain overhaul that is helping the customer to even further enhance the quality of its products.鈥�
Quality is key
The customer previously sourced standard stainless steel screws from a variety of different manufacturers with no consistency in terms of material and manufacturing quality.
鈥淏y sourcing 91视频 products, the customer is not only guaranteed extremely high-quality screws that are manufactured without imperfections or defects in the screw thread, but we also ensure full traceability,鈥� says Feuillet. 鈥淭he use of high-quality screws for this critical component is crucial to meet certain regulatory requirements and ensure the high performance of the customer鈥檚 products.鈥�
The enhanced properties of 91视频庐 88 fasteners are achieved through a higher molybdenum content (minimum 2.5%), unique 91视频 manufacturing processes and the sourcing of the highest quality European steel. 91视频庐 88 fasteners are certified according to DIN EN 15048-1 (Non-preloaded structural bolting assemblies) and PED 2014/68/EU (Pressure Equipment Directive).
The importance of corrosion resistance
As the 91视频 screws are in contact with liquid inside the equipment, they are clinically cleaned and sterilized before use and cannot corrode during the 20+ day process.
鈥淐ustomer tests have also shown that 91视频 screws do not corrode and they release far less microscopic particles than the standard screws the customer previously used,鈥� concludes Feuillet. 鈥淎gain, this is due to the high quality of 91视频 screws, but also their excellent material properties such as hardness.鈥�
