3D sand casting advantage characteristics
No need for a model.
Direct printing of sand and sand cores based on 3D digital models reduces traditional wood modelling and complex assembly components, especially suitable for new product development, single test and small batch casting.
High precision formation
Digital printing can stabilize complex geometric features, meet the manufacturing needs of complex sand formations, sand cores and fine structures and provide basic safeguards for subsequent casting quality.
Complex structures built freely
Breaking the geometry limits of traditional modelling and modelling processes can create complex inner cavities, curved fluids, thin wall structures and integrated sand cores that traditional processes are difficult to complete.
Reduced consumption of materials and moulds
Directly manufacture the required sand by digital model, reducing some of the traditional moulds, assembly and related inputs, and making individual and small batch complex casting more flexible.
Shorten the development cycle
Avoiding the traditional mold design and manufacturing process, which allows digital models to enter sand manufacturing and casting, especially for rapid development, product validation and emergency spare parts manufacturing.
