1.In die-casting production, when die-casting parts are stuck, you can use a spoon to pour the aluminum alloy onto the die-casting parts of the die (generally the weight is about the same as that of the die-casting parts). The die casting is thermally expanded, and the die casting of the sticking template is tried to be ejected by the ejector of the ejection cylinder, and the die casting of the static die is pried out with a chisel.（Bengbu Longhua Die Casting Machine Co.,Ltd.  www.longhuamachine.com/www.diecastingmachinechina.com） 2.If the above method does not work, the only way to remove the mold, with a chisel bit by bit to clean down the sticky mold casting.（Bengbu Longhua Die Casting Machine Co.,Ltd.  www.longhuamachine.com/www.diecastingmachinechina.com） 3.Check whether there is good spraying on the parts where the mold is overheated, such as the long core;（Bengbu Longhua Die Casting Machine Co.,Ltd.  www.longhuamachine.com/www.diecastingmachinechina.com） 4.Check whether the die drawing inclination of the die casting is maximized, and increase the die drawing inclination can reduce the adhesive mold;（Bengbu Longhua Die Casting Machine Co.,Ltd.  www.longhuamachine.com/www.diecastingmachinechina.com） 5.Check whether the mold is rough, or if there are places where the die is drawn backward, repair and polish these places（Bengbu Longhua Die Casting Machine Co.,Ltd.  www.longhuamachine.com/www.diecastingmachinechina.com） 6. If the die casting always sticks to the static template, you can deliberately rough the unimportant parts of the dynamic mold, increase the clamping force of the dynamic mold, so that the die casting will no longer stick to the static mold.（Bengbu Longhua Die Casting Machine Co.,Ltd.  www.longhuamachine.com/www.diecastingmachinechina.com）

China's economy has maintained a momentum of rapid development. As the contradiction between resources and the environment is increasingly intensified, according to the requirements of the scientific development concept, circular economy and clean production have become important national policies for sustainable socio-economic development. Experts point out that the total output of die-casting, that is, non-ferrous metal casting under various pressures including low-pressure casting and squeeze casting, is about 1.5 million tons. It is understood that the total national automobile production reached 7.28 million units, an increase of 27.6% year-on-year, of which 3.87 million cars were produced, an increase of 39.7% year-on-year. In 2012, the country's total output of die castings was 1024,000 tons, of which: 802,140 tons of aluminum die castings and 13,620 tons of magnesium die castings. From January to October 2012, the country's car production was 3.501 million vehicles, a year-on-year increase of 23.4%; sales of 3.601 million vehicles, a year-on-year increase of 22.0%. The die-casting market will still maintain rapid growth. Die-casting non-ferrous metal resources can be recycled and die-casting is advanced without cutting technology. It is especially suitable for the requirements of circular economy and clean production, and is in line with the general policy of national economic development. The light weight of automobiles has accelerated the development of the aluminum-magnesium die-casting market; the shift in the focus of international non-ferrous metal die-casting production to China has become an inevitable trend, and the die-casting market has huge room for development.

   The burr phenomenon of aluminum alloy is inevitable, and there are many methods to deal with the burr. In the production process of die casting, due to factors such as pressure shock and insufficient clamping force, burrs are inevitable. In recent years, with the increasing quality requirements of die castings, the requirements on burrs have become more stringent, and the methods of deburring have also emerged endlessly. The deburring process is the most troublesome. Today Bengbu Longhua Die Casting Machinery Co., Ltd. recommends the following pros and cons of various types of die casting deburring methods, so that you can better understand the various deburring methods and according to your needs Select the appropriate deburring method. 1. Artificial deburring  This is the most traditional and commonly used method in the die-casting factory. It uses files (files include manual files and pneumatic files), sandpaper, belt machines, grinding heads, etc. Disadvantages: labor costs are expensive, efficiency is not very high, and complex cross holes are difficult to remove. Applicable object: The technical requirements of workers are not very high, applicable to aluminum alloy die castings with small burrs and simple product structure. 2.Die deburring   Deburring is performed by using a production die and a punch. Disadvantages: Requires a certain die (rough die + fine die) production cost, and may also need to make a shaping die. Applicable object: It is suitable for aluminum alloy die-casting parts with relatively simple parting surface, which has better efficiency and deburring effect than artificial. 3.Grinding and deburring  This type of deburring includes vibration, sand blasting, rollers and other methods, which are currently used in die casting plants. Disadvantages: There is a problem that the removal is not very clean. It may require subsequent manual treatment of residual burrs or deburring with other methods. Applicable object: Suitable for small aluminum alloy die-castings with larger batches. 4, frozen deburring  The burr is quickly brittled by cooling, and then the projectile is ejected to remove the burr. The price of the equipment is about two to three hundred thousand;  Applicable object: Suitable for aluminum alloy die-casting with smaller burr wall thickness and smaller volume. 5, hot deburring  Also called thermal deburring, explosion deburring. By passing some easy gas into an equipment furnace, and then using some media and conditions to make the gas explode instantly, use the energy generated by the explosion to dissolve and remove burrs.  Disadvantages: expensive equipment (prices of millions), high operating technology requirements, low efficiency, side effects (rust, deformation);  Applicable object: mainly used in some high-precision parts and components, such as automotive and aerospace and other precision parts. 6.Deburring of engraving machine  The equipment ...
