What to Consider When Choosing an O-Ring?

图片
  You can have the most innovative and high-tech equipment, but if you don't install the   right O-ring , it can become useless. The importance of selecting the right O-ring for any application should never be underestimated, as the right size and material selection can be the difference between start-up and operation and failure.   Material Selection Selecting the right material for your O-Ring is important and is the starting point for your O-Ring purchase. Common material choices include   Nitrile (Buna-N):  This is the most widely used  O-ring material . It has excellent resistance to petroleum products. It also has excellent compression permanent deformation, tear resistance and abrasion resistance. It does not resist ozone, sunlight or weather very well unless it is specifically compounded. Temperature range: -40° to +250°F.   Fluoroelastomer:  This elastomer has excellent mechanical and physical properties, good resistance to petroleum prod...

Design Considerations for Reusable Medical Devices

  Designers must consider a number of factors when designing reusable medical devices. infection prevention Making reusable  medical devices  easy to clean is key to ensuring patient safety. Because of the risk of contamination from items used in patient care. For example, a stethoscope is a reusable medical device. However, studies have shown that users often do not follow relevant cleaning recommendations and there is a risk of cross-contamination. The study found that the use of copper on the stethoscope's diaphragm, binaural tubes, significantly reduced stethoscope colony formation. Abroad, a research team has developed a small box-style product that can be stuffed into the pocket of a medical coat. Once the user attaches it to the stethoscope diaphragm, the unit automatically begins UV cleaning that lasts three to five minutes. User friendliness Medical device designers must study how to make their products as easy as possible to interact with patients, suppliers, an...

What is CNC Thread Milling?

Thread milling is a conventional computer numerical control (CNC) manufacturing process. It is widely exploited for producing holes that adopt screws of varying sizes. Thread milling has numerous used in   machine shop , sometimes even replaces CNC tapping.  Let’s deepen into CNC mill machine, Threading process , types of thread cutters and learn more about its difference from tapping. What is Thread Milling? It is a metalworking process used to cut threads of varying sizes with the help of  machine spindles. In this case, the spindle is a rotatory part of a CNC thread mill that holds a cutting tool. By cutting off small chips of a previously made hole, CNC thread mills achieve threads of varying types. A single CNC unit can produce numerous types of threads, and the essential considerations here are the following: Left or right-handed threads.  They differ in the direction in which a screw’s thread wraps around its shaft. Left-hand threads were made by clockwise spi...
