Automotive parts sand molding machines are key equipment used to create sand molds in the casting process. They are widely used in the production of gray iron/ductile iron castings and other automotive parts, such as engine blocks, transmission housings, hydraulic components, valves, differential housings, and other complex parts. JinLi's upper and lower sand-shot molding machines, with their bidirectional sand-shot technology and high adaptability, can efficiently produce a variety of complex structural parts in the automotive parts casting field. They are particularly adept at solving the molding challenges of deep-cavity, thin-walled, and high-precision components. The following are the features and services of our upper and lower sand-shooting molding machines for automotive parts casting:

1、Utilizing upper and lower bidirectional sand-shooting technology, airflow-suspended sand addition solves the problem of sand-shot shadows in complex castings (such as those with high heights or deep cavities), improving sand mold compactness and casting accuracy.

2、Computer-controlled upper and lower chamber heights adapt to varying casting requirements and reduce the risk of chamber collapse. Widely used in the production of gray iron and ductile iron castings, including automotive parts (such as pump casings and motor heads), hydraulic components, and valves.

3、Intelligent control, equipped with a PLC system, allows for flexible adjustment of mold hardness parameters.
