Currently, the world's aluminum processing technology and equipment to
large, modern, sophisticated production line automation direction.
According to statistics, the world has been equipped with different
types of structure, purpose, pressure extruder of 7000 units or more,
more than 600 of its U.S., Japan, more than 400 units, more than 200
units in Germany, Russia and more than 400 units, the country of more
than 3,000 units, a large between the part of the 15-25MN small
extruder. Subway, high-speed trains and other modern transport
development requires a whole lot of siding and other structural
components, it is toward large-scale extrusion direction. After decades
of development, the world has been officially put into use tons or more
large extrusion machine about 20 units or more, has a national United
States, Russia, China, Japan Western Europe.
Current large-scale high-quality garden flat extrusion cylinder and
specialty abrasive technology has been a breakthrough. From the design
calculations, structure selection, handling methods, molding technology,
new materials development to improve in terms of life, etc. grinding,
squeezing workers abrasive technology has great development. Developed a
tongue like mold, flat Porthole Die, fork mold, mold front room,
diversion mold, removable mold width spread mold, water-cooled mold,
etc., while there has been active in various forms mold tool
automatically loading and unloading mechanism greatly simplifies the
work abrasive loading and unloading operations, saving auxiliary time.
In recent years, Russia, the United States, Germany, Japan and other
countries have developed 850MMX330MM, 1100MMX330MM geometric pressure of
600MPa or more large flat extrusion cylinder, allegedly life of 10,000
times. China has developed into 670MMX2700X1600MM large high-quality
flat extrusion cylinder. Large extrusion tool handling automation, rapid
technology has also made great progress, in order to create the
conditions for fully automated.
