How Does the Hole Get Inside Hypodermic Needles?

Did you know that suppliers for hypodermic needles use a very special process to create the small, but strong needles? Each needle must contain a narrow, hollow center inside the needle for collecting blood or administering medication. The process of creating these tiny, hollow metal pieces made from stainless steel is quite interesting, and most companies will use a similar process to create their own needles. If you have ever wondered how hypodermic needles are created, look no further.
First, the factory takes a long stainless steel billet and heats it to a pliable temperature. The factory then rolls the billet into a cylindrical shape. The factory then punches a hole through the center of the billet to create a tube. This seamless tubing is ideal for creating hypodermic needles.
The factory then stretches the tube through a die. This makes the tube longer and thinner, transforming a thick metal tube into the tiny tubes necessary to form needles of various sizes. The factory will run the tube through the die several times while hot, then one or more times while cold to give the tubes extra strength, even in their tiny size. If you have ever tried to break a hypodermic needle, then you know how strong they can be!
The factory finally cuts the tiny tubes to the desired length. The length will vary depending on the use for the needle. Some suppliers for hypodermic needles provide a wide range of needle widths and lengths, while others create only one or two types of needles. After manufacturing, the factory will clean and sterilize the needles before packaging them into the medically-approved packaging required by law. After packaging, each needle package is sent to another store for retail sales. Usually, a factory will not sell the products directly to the final consumer.
