What is the process of pushing out?
Often the parts are designed to be from a certain complex pattern of cross -section, with fittings, flanges, protrusions and flat edges, which must be integrated into a particular shape with specific tolerances in the finished product. The production of these specialized shapes or cross -sections is usually done by means of an extrusion process. This process uses heat, pressure and cooling to create half -board or paste that will be forced to die, and after emerging from death, it solidifies to a specified temperament. However, ceramics, heavier metals or alloys and foods such as pasta are also formed and produced in the process of extrusion. Essentially, if the material is easily liquefied, it can be extruded. The flowers, parts and pieces of brittle material that are difficult to shape by means of stamp, bending or hammers. Complex cross -sections, such as hollow pipes or solid pieces or bars with flange or wings, are much easier to push during the process of extrusion. The finished surface of the extruded products is onMore permanently better than the surface of stamped or pressed products.
In principle, the pushed process involves loading small pieces of raw material or supplies into the hopper at one end of the extruder. In the case of the plastic extrusion process, this raw material is called pellets and in the process of extruding the aluminum of the Sochor. The raw stock is powered from the hopper to the element, basically a heated cylinder where it is softened. RAM, usually worm gear, forces the semi -published raw material through a smaller chamber, then through the shaped matrix. From DTJ. Extrusion, string, tube or rod of shaped material is cooled by water or air, along the table to solidify. At the end of the table, the hardened product is cut, wound, sent or sent for another refine.
heated and cold raw materials are adapted for processing. Of course, cooler raw materials such as pellets or sochors require much higher pressure to donutILY smaller chilling material with a smaller chamber and death. Temperature and pressure factors in the extrusion process are essential for temperament, strength and finite finish. The ratio of extrusion, division of the cross -sectional area to die through the cross -sectional area of the extruded product is also essential in determining the best method of pushing, cold or hot, high pressure or low pressure.
