When referring to an extrusion, the industries that use or make these imagine something that is formed from a quantity of material into a regularly shaped item in a long form. This is best described as the Play Do machines you had as a child. The do is placed in the forming machine and squeezed out of different shaped dies. Aluminum is done this way as is sausage when it is being formed. A rubber extrusion is the same process except they are much more flexible.
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.
Medications often are administered through rubber tubing. These items must be as strong as possible because they should not break no matter what is in them. Some of these sanitary tubes are embedded in a living body because of the breakdown of a vein or an artery. They must be strong in order to last long enough for recovery to occur.
Tubes, highly cleanable tubes, are needed for food production as they bring ingredients from the storage tanks into the blending areas. They need to be able to be sanitized and they must be strong and able to bend around corners. Occasionally, they will need to be run over by pallet jacks and bounce back into shape as only rubber can.
What an extrusion gives you that spliced pieces do not is a safe, secure seal that will have to break in order to fail. This seamless piece will not allow the voids that could occur in a temperature shift like other materials will. The security of this is not accessible with having to manufacture a seal from several pieces and should not be attempted for any critical application.
Whether you are involved in the food industry, refrigeration or the ever expanding aerospace industries, extruded rubber products are the way to go. Just ask the engineers that are charged with the design and safety of those systems. The never ending system of extrusion for this flexible material will make a decision easier to make.
