What is an extrusion machine?
The extrusion machine is a device that pushes or pulls the material through the shaped matrix to create a continuous product length with a preset cross -section. The extrusion process is used to produce a large number of commercial products that include steel or copper wire, plastic hoses, plastic leaves and many types of food. The extrusion as a production process offers many advantages, such as a wide range of possible complex cross -sections and the ability to form fragile materials. Depending on the material used, the extrusion may create a cold or hot material, with some types of materials completely melting before pushing. The bag is filled with icing and equipped with a decorative pipe nozzle. If the bag is pressed, the topping fills the nozzle and is pushed or pushed as a continuous length with the same cross -section as the shape of the nozzle hole. This is the same basic principle as jandustrial extrees used to create many products using plastics, metals and food or pharmaceutical ingredientsand. The only real diversion from this simple example is the complexity of cross -section, the inclusion of hollow cores and the fact that some machines stretch the material through the matrix rather than push it.
The extrusion machine can be used to produce a wide range of products from the same size of raw materials. It is also an attractive alternative to other manufacturing processes as it allows for greater selection of profiles and is suitable for use with fragile materials. In industrial applications, plastics are extruded to produce a film about food packaging, sheets, insulation, car parts and hose products such as electric lines and plumbing pipes. Steel and alloys are extruded to form rods, pipes and conductors, as well as steel pipes of allegation construction for light engineering. The food and pharmaceutical industry also widely uses extrusion in the production of products such as pasta, cereals, suSenka and several drugs of drugs.
In several extrusion applications, especially those used by plastics, there must be a material to be extruded before use to warm them to the melting point. These applications usually use a screw feeder mechanism similar to the one that is used in the injection molding process to heat and feed the material. Cold displacement is also a common process of extrusion and is usually limited to metals such as tin, lead, steel, aluminum and copper. The cold extrusion has several advantages over the hot process, such as lack of oxidation, better finishes and faster pushes. To produce objects such as car pistons, steel cylinders, tubing and empty gearboxes, it is used to produce objects such as pistons, steel cylinders.
