Profile extrusion

Our country profile extrusion machine variety, the level of high and low, also for the world. Have our own factory of simple extrusion machine, useful squeezed plastic machine, there are a few homebred, second is mostly in Taiwan, Japan, the United States and Germany, have pressure, oil pressure. In short, there are hundreds of extruders in China. It is widely believed that Japan, the United States and Germany are better extruders, followed by Taiwan. Good and poor extruding machine, same cast bar, extruded profile quality is no different. We often see the building aluminum doors and Windows with 6063T5, which is the American brand international general. The Chinese brand is LD31RCS. T5 and RCS are both states, indicating the state of artificial aging of wind and cold quenching. The quenching of metal is suddenly reduced to a low temperature, such as the steel knife blade must be quenched in the water, it is hard and sharp, while the quenching of aluminum is also quenching and quenching. The construction of 6063 profiles is used to quench the heat and chill, and then put the hardened aluminum in the aging furnace for a certain time. The internal crystallization of aluminum is rearranged, and the mechanical strength is obviously improved. In all metal alloys, only aluminum has an aging condition.

Each manufacturer, although generally passes the aging, but the effect difference is very big, this is related to the extrusion temperature of the aluminum extruder, the extrusion speed, and the wind and cold speed of the extruded machine is related to the wind volume. If some factories, in the extruder outlet, only one small fan, some manufacturers one line more than ten fans. As soon as possible if you can't squeeze out of the more than 500 degrees profile rapidly cooled to below 200 ℃, called incomplete hardening, aging after aluminium material strength is not very ideal. In recent years, some aluminum producers have to reduce the weight of aluminum. Reduce the weight of aluminum doors and Windows per square meter, thus reducing the cost of aluminum doors and Windows, catering to the requirements of some aluminum doors and Windows manufacturers bidding prices, producing thin-walled aluminum profiles, which is very dangerous. Because each series section, is after careful calculation, and satisfies the requirement of load-bearing and determine the section shape and wall thickness, without computing could not reduce at will the thin, otherwise intensity is decreased obviously. On July 19, 91, the typhoon hit the guangdong chaoshan area, a lot of aluminum alloy doors and Windows and the wind blow out a lot of people are above, there is a building 1910 square meters of aluminum doors and Windows even scrape, doors and Windows are destroyed, more than 40 units of shantou loss 1.83 million yuan only. Why the road is so badly damaged, all the damaged aluminum doors and Windows, a few flat is thin wall aluminium profile making the most book only 0.6mm thick. In shantou aluminum profile thickness of over 1.2mm aluminum window, very little damage. So thin-walled aluminum profiles are real fake products. The wall thickness of the normal aluminum profile shall be as much as, 70 series and 90 series aluminum window wall thickness is 1.2 ~ 1.4 mm, aluminum door profile shall be 1.2 ~ 2.0 mm, and the wall thickness of aluminum curtain wall shall be more than 3mm. The thin wall profile is serious and harmful, and the user should not be used for cheap aluminum alloy thin wall profile.
