The Difficulty of Stainless Steel Housing of Biofilter in Precision Machining: Process Skills and Key Points

2024-06-28
In the field of biopharmaceuticals and medical devices, biofilters play a vital role, as the core component responsible for removing and filtering microorganisms, particulates and other contaminants in liquids or gases, the corrosion resistance, precision and quality of stainless steel materials have become the focus of the manufacture of biofilter housings. But in fact, the machining process of stainless steel housing is also full of challenges.
      Next,this article will introduce you to the difficulties and process requirements of the processing of the stainless steel shell of the biofilter.

Selecting materials  severely according to product characteristics
      The housing of a biofilter often requires extremely high processing accuracy, including dimensional accuracy and surface finish. At the same time, since biofilters may be used in sterile environments, their housings also need to have excellent corrosion resistance, high temperatures, and cleanliness to ensure a clean processing environment and avoid microbial contamination.
      Stainless steel is the best material choice. It not only has ultra-high deformation resistance and hardness, but also can cope with the high-strength cutting and processing strength generated in the machining process. At the same time, the heat treatment and corrosion resistance of stainless steel are also quite excellent, and the temperature of 304 stainless steel can be as high as 800°C.

Cautious operation of processing technology
      The stainless steel housing of a standard biofilter needs to go through multiple processing steps. From the early stage of material selection, drawing design, blanking and cutting, welding, to the surface and chemical treatment, assembly and inspection of the product after forming, each step needs to be carefully and meticulously operated.
      Among them, the welding process is the key point, the quality of welding is not only related to the stability and integrity of the overall structure of the product, but also directly affects the operation safety of the product! Improper operation of the welding process can even seriously lead to liquid leakage or rupture during the operation of the biofilter!

      Developing technology is the key to sustainability
      As a global enterprise with a deep understanding of precision machining technology, Zhuhai Chuntian Technology Co., Ltd. (CTT) has not only accumulated rich experience in the field of precision manufacturing, but also committed to continuous innovation and process research, through continuous exploration and practice, and gradually overcome various difficulties and challenges encountered in the working process, which also makes us gain a high degree of  trust from Pall corporation and other enterprises.
