In the past decade, under the combined influence of policy, technology, population and environmental factors, China's biomedical and medical device industry has developed rapidly like a high-speed train of the times. However, with the continuous advancement of medical technology, the precision, quality and reliability requirements of Medical Equipment are also getting higher and higher, whether it is surgical instruments, biofilters or high-end diagnostic imaging equipment, precision machining is a key factor in achieving the performance requirements of these equipment.

Next, this article will explain and introduce the importance of precision manufacturing technology in the field of life sciences around biofilters.

What is a biofilter

In plain English, a biofilter is an efficient purification device, which usually consists of one or more filter media, which can be physical barriers, such as microfiber membranes; It can also be biologically active materials that promote the adsorption and subsequent biodegradation of microorganisms. The great thing about biofilters is that they can efficiently capture particles of 0.1 microns and above, including bacterial and fungal spores, which is of great significance to food processing, medical and other industries.

An important component of a biofilter: a stainless steel filter housing

While the medium of the biofilter is important, the importance of its stainless steel housing cannot be overlooked. Due to the complex working environment, biofilters are widely used in biomedical, food, processing chemical and electronic industries, and have strict requirements for the material, sealing, corrosion resistance and structural stability of the shell.

For example, the PhaseSep EL coalescer from Pall's chemical filter system provides excellent separation cleaning for applications containing oil, natural gas, corrosive liquids, or high-temperature fluids. In the face of such a severe working environment, the precision machining technology of the stainless steel filter housing is even more important.

So with many years of experience in precision manufacturing and processing, Zhuhai Chuntian Technology Co., Ltd. (CTT), how do we realize this difficult technology?

CTT & Pall：Core technology, win-win cooperation

In addition to incoming cutting, CNC machining, surface treatment and other processes, we pay more attention to the welding process of stainless steel filters. This is because the fineness of the welding process not only determines the appearance and consistency of the filter housing, but also affects the working stability of the filter. Smooth, defect-free, absolutely sealed welds are the key to the long-term smooth operation of biofilters, and improper welding processes will not only destroy the protective layer on the surface of the material, leading to corrosion problems, but also directly related to filtration effectiveness and safety!

As a long-term partner of Pall, CTT understands that the enclosure processing products we provide are critical to the proper functioning of biofilter equipment. Therefore, over the years, we have been committed to promoting equipment innovation and process optimization, and breaking through new dimensions in products and services through our own lean concepts, which has enabled us to achieve a global corporate layout.

With the advancement of technology and the growth of industry demand, we look forward to cooperating with more companies like Pall to jointly promote the development of medical and health care and make greater contributions to human health.
