Reasons for insufficient pouring of aluminum alloy die castings and wall thickness requirements

Release date:2017-06-30 Author: Click:

Aluminum die castings often have insufficient pouring during the production process. The main reason is that the metal mold conducts heat too quickly, and the melting point of aluminum is low, which will directly cause the molten aluminum to flow. It will cool in advance without filling the cavity.


The metal model of aluminum die-casting parts has certain requirements for wall thickness. If the wall thickness of the product is too thin, other processes need to be effectively considered at this time, such as die-casting and aluminum die-casting are a kind of pressure-casting parts , It is a die-casting machine with a die-casting machine equipped with a casting mold.


The aluminum die-casting parts will effectively pour the heated liquid aluminum and aluminum alloy into the inlet of the die-casting machine during use, so that the die-casting machine can be effectively die-casted, so that the casted mold is limited in shape and size Aluminum parts or aluminum alloy parts.


In order to effectively avoid insufficient casting of aluminum die-casting parts, it is necessary to effectively increase the casting temperature and heat and keep the mold necessary during use, or spray thermal insulation coating directly inside the mold to effectively improve The pouring system makes the pouring more smooth.


When aluminum die-casting parts are manufactured, metal parts with complex shapes and clear outlines can be manufactured. During use, because molten metal maintains its high fluidity under high pressure and high speed, it is difficult to obtain other processes during use. Machined metal parts.


The dimensional accuracy of aluminum alloy die castings is relatively high, sometimes up to IT9 level, and the material utilization rate of the entire product is relatively high. Because the accuracy of the product is relatively high, only a small amount of mechanical processing is required during use. Can be assembled and used.
