The holding time of flat mold with diameter less than 200 mm shall not be less than 2 hours, and that of split mold shall be more than 3 hours; The mold with diameter more than 200 mm shall be kept for 4-6 hours to ensure the uniformity of the core temperature and external temperature of the mold. 5、 Before mold trial or production, the inner liner of the ingot container must be cleaned with the cylinder cleaning pad, and check whether the extruder runs normally. 6、 When the die is tested or the production is just started, the automatic gear of the extruder will be turned off and the switches of each section will return to the zero position. Starting from the minimum pressure, slowly start to press and discharge for about 3-5 minutes. During the aluminum filling process, mainly control the pressure. The pressure is controlled at 100kg / cm ² The ammeter data is within 2-3a, generally 80-120kg / cm ² The extrusion speed is less than 120kg / cm in normal production ² Subject to. 7、 In the process of trial or production of aluminum alloy profile mold, if it is found that the mold is blocked, tooth offset, too large deviation of speed and so on, it is necessary to stop the machine immediately and unload the mold in the way of point withdrawal, so as to avoid the scrapping of the mold. 8、 In the process of die test or aluminum production, the discharge

Foshan Sanshui Xin Yi Kang Ke Metal Product Co,.Ltd., provide customers with high quality aluminum deep processing service.Aluminum extrusion heatsink.china custom aluminum profile.You can browse related products and initiate consultations on our website. Aluminum alloy is widely used in heat dissipation equipment because of its light and beautiful quality, good thermal conductivity and easy to be processed into complex shape. Aluminum alloy heat dissipation equipment mainly has three types: flat width, comb or fish thorn; The heat sink outside the circle or oval is radial and branch shaped. Their common features are: the distance between the fins is short, and a groove is formed between the adjacent two fins, and the ratio of depth to width is large; The wall thickness difference is large, the heat sink is thin in general, and the thickness of the bottom plate at the root is large. Therefore, it is very difficult to design, manufacture and produce the die of the heat dissipating profile. Some products with smaller size and symmetrical shape are easy to produce. Most of the radiator profiles are flat and wide, with large size and some asymmetry. The ratio of groove depth to width between fins is very big, and it is difficult to produce. It is necessary to cooperate with ingot, mold and extrusion technology to produce radiator profile smoothly. The alloy used for extrusion radiator profile must have good compressibility and heat conductivity, and the alloy 1a30, 1035 and 6063 are generally used. At present, 6063 alloy is widely used, because it has good extrusion and heat conductivity, and has good mechanical properties. The production of aluminum alloy radiator profile should be started from the quality of ingot, material and design of mold, reduction of extrusion pressure and extrusion technology. 1. Quality requirements for ingots The alloy composition of ingot should strictly control impurity content to ensure the purity of alloy melt. For 6063 alloy, the content of Fe, Mg and Si should be controlled. The content of Fe should be less than 0.2%. The content of Mg and Si is generally controlled at the lower limit of national standard, Mg content is 0.45% ~ 0.55%, Si content i

LED is known as the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, small size, etc., and can be widely used in various indications, displays, decorations, backlight sources, general lighting and urban night scenes. In recent years, some economically developed countries in the world have launched fierce technical competitions around the development of LEDs. The United States has invested 500 million US dollars to implement the "National Semiconductor Lighting Program" in 2000, and the European Union also announced the launch of a similar "Rainbow Program" in July 2000. With the support of the "863" plan, the Ministry of Science and Technology of my country first proposed the development of semiconductor lighting plan in June 2003. Over the years, LED lighting has been valued by the state and governments at all levels due to its advantages in energy saving and environmental protection. Various localities have introduced relevant policies and measures to accelerate the development of LED lamps. Consumers have also longed for this new environmentally friendly lighting product. Long. However, due to the high cost of investment in technology and promotion, the LED lighting products that thousands of consumers have been waiting for have been out of reach, and the mysterious aristocratic veil has not been unveiled for a long time!    With the reduction of technology and production costs of some domestic manufacturers, the situation that LED lighting is popular but not popular is about to change. Cheap and good-quality LED lighting products will bring a revolutionary impact to China's lighting industry and bring bright gospel to consumers!    Advantages:   High energy-saving: energy-saving energy without pollution is environmental protection. DC drive, ultra-low power consumption (0.03-0.06 watts per tube) electro-optical power conversion is close to 100%, the same lighting effect is more than 80% energy-saving than traditional light sources.   Long lifespan: Some people call the LED light source a longevity lamp, which means a lamp that never goes out.

What is aluminum plate?
26 Jul 2021

What is aluminum plate? Aluminum plate refers to aluminum material with a thickness of 0.2mm or more to 500mm or less, a width of 200mm or more, and a length of 16m or less.It is called aluminum sheet or aluminum sheet, 0.2mm or less is aluminum, and 200mm width or less is the row or strip (of course With the progress of large equipment, there are more aluminum plates with the widest width of 600mm). Aluminum plate refers to the rectangular plate made by rolling aluminum ingot, which is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium-thick aluminum plate, and pattern aluminum plate. Aluminum plates are usually divided into the following two categories: 1.According to alloy composition: High-purity aluminum plate (rolled from high-purity aluminum with a content of 99.9 or more) Pure aluminum plate (the composition is basically made of pure aluminum rolled) Alloy aluminum plate (composed of aluminum and auxiliary alloys, usually aluminum-copper, aluminum-manganese, aluminum-silicon, aluminum-magnesium, etc.) Composite aluminum plate or brazed plate (a special purpose aluminum plate material is obtained through a variety of material composite methods) Aluminum-clad aluminum plate (a thin aluminum plate is coated on the outside of the aluminum plate for special purposes) 2. Divided by thickness: (unit mm) Aluminum sheet 0.15-2.0 Conventional board (aluminum sheet) 2.0-6.0 Aluminum plate 6.0-25.0 Aluminum plate 25-200 Super thick plate 200 or more
