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.
