Why Rubber Extrusion Is Used In Aviation And The Food Industries

By Estelle Larsen


Extrusions are those things that come out of a forming die to be used for a number of different things. This was true when you played with Play Do as a child and it is true today. Many industries use parts coming out of an extruding machine for all sorts of things. There are many materials that can be extruded, however, the most flexible material is the rubber extrusion.

What the technicians put into the machine is the raw rubber with various compounds mixed in. This machine will melt the rubber and prepare it for the forming it must go through. It will then be directed to a barrel ending at the forming die. This die is the most important part of the piece of equipment.

Very important are the dies to the overall production of extruded items. They are designed to exacting standards and out of strong steel. They usually have to stand up to a lot of pressure. Flat bars can be formed or round tubes. Many of the round holes will have an additional device that will allow a hole to be formed through the length to form a passage.

Some of the uses for these extrusions are seals for many things. The space industry needs very strong extremely flexible seals for their space craft and even for airplanes undergoing a lot of stress during flight. These seals are not just a simple flat piece but can have several different planes or geometries involved in their forming. These are accomplished by the fine machining of the die used.

The need for sanitary tubes for the administering of medications is a good reason for this type of extrusion. There are also tubes, as you know, that must be inserted into the living body to replace arteries and veins that have failed. These must be strong, able to be sanitized properly and should last for quite a while.

Food production processes employ a large number of sanitary tubes for the movement of ingredients and additives. These tubes must be strong and able to be moved around and even run over with material handling gear and spring back into shape. The nature of rubber allows for this and the cleanable tubes make everything faster and easier.

These kinds of extrusions are better than the older method of cutting pieces of material for seals and piecing them together. The process being discussed makes a single piece without any splices and able to resist leaks, as appropriate, or voids that can endanger what is being protected. This provides a level of security that was not as possible before this process was invented.

Seals in aerospace applications and safety for food being processed are benefited by these types of rubber items. Safety of your prescription drugs, maintaining the temperature of items placed in a refrigerator or freezer is also very important. The many forms that can be designed and brought out of a batch of rubber are what make the modern world the safe and secure place it is.
