aluminum castings have an inextricable relationship with the automotive industry. In the long run, the increase in the number of cars and the rise in aluminum castings is parallel, and aluminum castings can help car parts to be lighter. The increase in aluminum consumption per car is accompanied by an increase in automobile production in the world. .
    Hangzhou Hongcheng Pml Precision Mechanism Ltd is a Hangzhou aluminum casting manufacturer. Hangzhou is a city with rapid economic development in China. The annual output of automobile is not increasing, and the macro becomes a variety of aluminum casting products for customers to make aluminum alloy sand casting and aluminum sand casting.

    large aluminum castings in the solidification process. Due to the blocking effect of mud core, the shape of the casting is not consistent with the shrinkage rate of the core cavity. The hard sand can be placed in the water glass core or the resin sand core, and the sawdust should be added to the water glass sand 3% to 5% to improve its concession. For aluminum castings with larger plane direction and smaller direction, the models and castings are easily deformed, and are treated according to the concrete structure and shape of the castings. The thinner and thinner plates are more difficult to fill. When designing gating system, aluminum melt should be filled up as quickly as possible.
