Aluminum alloy cabins are a type of revolving barrel wall casting, in which the wall thickness is uneven, and hot spots are distributed in the upper, middle and lower parts. It is a fully processed product, thus, after processing, the product must not show any casting defects, and needs to meet the requirements in appearance, size and performance. In this paper, based on the casting structure, combined with low-pressure casting equipment, process research and analysis of the product's pouring system, metal structure, process parameters, etc., are carried out. Practical results show that the gating system of the product designed with a metal mold and a sand core can be embedded in the sand core, so that the pouring system can fully feed the hot spots of the product. A reasonable processing allowance can achieve the least raw material consumption. Suitable metal structures and process parameters can realize stable filling and continuous production of products.
