| surface treatment methods are: anodic oxidation | | | | "Construction" mainly refers to the doors, |

| Melting and ingot casting | | | | industrial aluminum proportion of 28%. With China's |

| homogenization attach great significance. | | | | In accordance with international practice, the |
| At present, about 70% of the construction is | | | | extrusion of the industrial uses are divided into: |
| aluminum with the same level of hot top casting | | | | transportation, consumer durables, electronic |
| of the ingot extrusion system production, there | | | | equipment, machinery and equipment, containers |

| Aluminum for the fully automated, Hing Fat | | | | materials is reasonable. |
| aluminum Profile Factory Co., Ltd. first introduced | | | | Aging |
| in 1989, such equipment. China now has basically | | | | Architectural Aluminum is AL Mg Si alloy extrusion, |
| mastered the manufacture of such equipment, | | | | and to go through artificial aging treatment. |
| technology and round ingot casting process. 2008 | | | | National Architectural Aluminum Manufacturer of |
| China's domestic production of about 155 units on | | | | about 1350 units aging furnace, with a total |
| the same level of hot top casting machine. | | | | processing capacity of about 4500kt a. China's |
| China has also introduced five units within the | | | | handling of 6063 type system of multi alloy |
| British black Gemu Lin's guide hydraulic casting | | | | profiles for the 200 ? insulation 1.5h ~ 2h, rather |
| machine. National round ingot casting machines of | | | | than 175 ? insulation 8h best system, although the |
| the total production capacity of 6000kt a, put it | | | | mechanical properties up to standard |
| aside for about 1200 sets of smelting furnace | | | | requirements, but the performance potential of |
| group. | | | | the alloy has not been fully realized. Also in the |
| Chinese construction enterprises Aluminum | | | | extruder when the cooling rate of quenching was |
| Extrusion regenerative melting furnace put it | | | | generally not enough, that the profiles from the |

| recovered waste heat, the former high thermal | | | | 300 ?. |
| efficiency up to 55%, which is lower, and some | | | | Extrusion output |
| do not to 30%. Therefore, the industry average | | | | 1979 ~ 2008, this 30 years China and |
| thermal efficiency of nearly 45%, compared with | | | | architectural aluminum extrusion production |
| more than 65% of the industrially developed | | | | average annual growth rate of 38.28%, the real in |
| countries is much lower, but lower than 33% of | | | | a sustained, stable and fast development |
| domestic total energy and high a lot. | | | | momentum in the world's aluminum extrusion is |
| Most of extrusion plants in China are melting shop, | | | | unprecedented in the history of industrial |
| there are about more than 85% of the ingot is | | | | development . |
| produced by extrusion plant itself, while the | | | | 30 years of reform and opening up, China's total |
| industrially developed countries have more than | | | | production of extruded aluminum for |
| 70% of the ingot casting by aluminum factory or | | | | 39.544.385kt, the total output of construction |
| professional production plants. The domestic | | | | Extruded 28475.135kt, industrial production of |
| situation must be improved. Most have aluminum | | | | extruded profiles 11069.25kt, squeezing of the |
| extrusion ingot plant in the industry can improve | | | | construction materials production accounts for |
| economic efficiency, saving energy and raw | | | | production of extruded profiles 72.0 %, and other |
| materials, environmental protection is also helpful. | | | | kinds of industrial extruded profiles of the total |
| At present, there are a number of large aluminum | | | | profiles of the total 28%. If the squeeze tube is |
| plant have been built or are building high tech | | | | counted, then the proportion of industrial extrusion |
| foundry ingot. | | | | materials will be larger. |
| Mold | | | | Extruded aluminum import and export volume and |
| Aluminum extrusion die is one of the most critical | | | | apparent consumption of |
| equipment, the price about 8% of the cost of | | | | 1984 ~ 2008 China's apparent consumption of |
| aluminum manufacturing. To extend the service | | | | aluminum extrusion was the general upward trend, |
| life of dies to reduce the production costs are | | | | as of 2008 China's output of aluminum extrusion |
| important. China's medium sized architectural | | | | 7553.472kt, import volume 62.035kt, the export |
| aluminum extrusion plant are mostly that they | | | | volume of 262.730kt, net imports To 200.695kt, |
| have mold manufacturing workshop, but some | | | | apparent consumption of 7352.777kt. Due to the |
| medium sized enterprises and almost all of the | | | | global financial crisis, in 2008, net exports fell. |
| small business is purchased or contracted out to | | | | China was the last century the late 80s and early |
| mold the professional mold manufacturing | | | | 90s there have been a net exporter of the |
| enterprise. China has 275 construction companies | | | | phenomenon, but in 2001, China became a net |
| are not producing aluminum molds, accounting for | | | | exporter of aluminum continuous, and along with |
| 49.11% of the total number of enterprises. | | | | China's accession to WTO and the Chinese |
| China in the mold materials, design, manufacturing, | | | | aluminum market, improvement of |
| surface treatment, repair mold technology and | | | | competitiveness, as well as The strengthening of |
| size detection technology, life, etc. and there is a | | | | foreign trade, profiles of net exports would |
| large gap between the industrialized countries, | | | | increase every year. |
| CAD CAM technology is not widely used, die an | | | | Aluminum of China's exports in 2008, the average |
| average life expectancy is only 6 , 7 tons, and a | | | | price of 2921.09 U.S. dollars t, the average price |
| far cry from the industrialized countries for more | | | | of imported aluminum 3289.52 U.S. dollars t, the |
| than 20t. There are many factors affect the die | | | | average price of imported aluminum higher than |
| life, such as, composition and manufacturing | | | | that of exports by 12.7%, showing that imports |
| methods, design, surface treatment, repair mold | | | | are higher added value or domestic currently can |
| technology, large or small, have a relationship. | | | | not produce high tech precision aluminum alloy |
| Therefore, improving the die life is a complicated | | | | industry. However, the price difference between |
| systematic project, the need for longer term | | | | import and export of aluminum is not that the |
| development. | | | | quality of China's aluminum round to catch up with |
| Energy saving window insulation cold bridge | | | | the world advanced level. |
| aluminum profile | | | | From the last century, China has been since the |
| In recent years, China's construction market on | | | | mid 90's aluminum windows and doors and their |
| the energy saving rapid development of plastic | | | | frames, thresholds and aluminum structural parts |
| doors and windows, has accounted for more than | | | | of a net exporter, and the net export volume |
| 35% market share. As the door window frame | | | | increased year by year, 1998, net exports |
| area of about 30% of the entire window area, so | | | | 41.064kt, 2008 years of 553.928kt, 10 years, an |
| in order to achieve the purpose of an effective | | | | increase of 12.5 times the average annual increase |
| energy saving moisture, the door window frame | | | | of 31.52%. |
| material selection very important. Europe and the | | | | 1999 import and export of aluminum doors and |
| United States as early as 20 years of money out | | | | windows of the unit price difference of 3559 U.S. |
| of Asian countries on the development of highly | | | | dollars t, while in 2008 this value is 3999 U.S. |
| effective energy saving aluminum doors and | | | | dollars t; However, in 1999 unit price of imports |
| windows materials: insulation cold bridge aluminum | | | | of aluminum doors and windows of the unit price |
| door window frame profiles, their energy saving | | | | than the exit doors and other high 172.8%, while |
| performance compare very favorably with steel. | | | | the 2008 years, the ratio of reduced to 107.8%. |
| Since the 20th century, since the early 90s, China | | | | This can be drawn, the added value of imports of |
| has introduced a thermal aluminum production line, | | | | aluminum doors and windows is much higher than |
| production capacity of about 420kt a. The | | | | exports, but this value decreased rapidly, indicating |
| production process of this profile are: Rolling | | | | the quality of Chinese products in a large margin. |
