Extrusion is a process widely used in manufacturing in which molten material is extruded through a mold into a specific shaped strip or block product.This process uses an extruder,which shapes the material by heating and applying pressure,and gets the desired shape after cooling.

　　1.Plastic products

　　Extrusion plays an important role in the manufacture of plastic products.By extrusion,plastic products of various shapes can be produced,such as pipes,plates,films,threads,seals and so on.The extrusion process can be customized according to the characteristics of plastic pellets and application requirements through the selection,refining,heating,extrusion and cooling steps of the extruder.

　　2.Metal products

　　Extrusion can also be used for the processing of metal materials.By applying the appropriate profile die,the metal can be pressed into products of various cross-section shapes in the metal extrusion press.For example,aluminum alloy doors and Windows,aluminum alloy profiles,etc.,are manufactured through the extrusion process.Extrusion can make metal materials with high strength,good hardness,corrosion resistance and other characteristics,and can produce more lightweight and beautiful products.

　　3.Food processing

　　In addition to plastic and metal products,extrusion is also widely used in the food processing industry.For example,the extrusion process can be used to produce various shapes of food such as rice cakes,pasta,and breakfast cereals.Extrusion can make the food have a better taste,shape,and can be produced efficiently.

　　All in all,extrusion is a versatile manufacturing process with a wide range of applications.Whether plastic,metal or food processing,extrusion can be customized to the desired product shape,improving production efficiency and providing better product quality.

　　Sum up

　　Extrusion is an important manufacturing process where pressure is applied to squeeze molten material into a product of a specific shape.It is widely used in plastic products,metal products and food processing industries.The extrusion process can be customized in a variety of shapes and provides efficient production methods and superior product quality.
