There are two types of swabs for nucleic acid testing and antigen testing, namely nasal swabs and pharyngeal swabs. The pharyngeal swabs are usually 15 centimeters long, and the nasal swabs are 6 to 8 centimeters long. The "cotton swabs" you see for sampling are not the same as the skim cotton swabs we use every day. It is mainly composed of nylon short fiber pile head and medical grade ABS plastic rod.

Injection molding is a widely used manufacturing process in the medical industry, providing many advantages for a variety of applications. Medical grade plastic injection molding is used for medical devices, components, laboratories and facilities. One of the key advantages of the injection molding process is its ability to meet the stringent regulatory and regulatory needs of the medical industry, which we discuss in further detail below. Benefits of injection molding for medical devices Medical [...]

Computer numerical control (CNC) machines have become a standard in the machining industry. Their accuracy, speed, and ease of use make them indispensable tools. But despite these advantages, they’re still not perfect. Quality control remains an essential step to catch and prevent defects, yet many facilities have sub-par CNC quality control systems. While errors are far less likely with CNC machines than manual processes, they can still happen. When they do, they can create [...]

When designing any part for injection molding, it is important to consider the shrinkage and contraction rate of the material and the associated geometry of the component. Plastic shrinkage is the dimensional change that occurs in a molded part as it cools after injection. Most of the part shrinkage occurs while still within the molding tool during the cooling stage, but a small amount of shrinkage occurs after ejection, as the part continues to [...]

The essence of medical injection molding is to manufacture medical components and devices using durable, reliable and FDA-compliant medical grade plastic materials. The medical plastic injection molding process is cost-effective and ideal for mass production operations and applications requiring consistency and tight tolerances. This molding process is also used for medical device prototype development and laboratory testing during the FDA approval process. RJC is a leading supplier of injection molding components for medical plastics. [...]
