What is lost foam casting mold?
Lost foam molds casting is a solid molding of a foam mold using a non-bonding agent dry sand combined with vacuuming technology. The foam model similar in shape and shape of the casting is bonded and combined into a model cluster, which is coated with refractory paint and dried. vibrating screen modeling in dry quartz sand, casting under negative pressure, gasifying the model, liquid metal occupying the position of the model, and forming a new casting method after solidification and cooling.
The dry sand buried model can be used repeatedly, with less industrial waste, no flash burrs, and the cleaning time can be reduced by more than 80%, and the cost is significantly reduced.
Wide range of applications
Not only can cast iron, ductile iron, but also steel castings at the same time, so the transfer is flexible and has a wide range of applications.
It is not only suitable for large-scale castings, mechanized operation, but also for hand-splicing models of small batches of products.
Not only suitable for small and medium-sized parts, but also suitable for large castings, such as: machine bed, large diameter pipe fittings, large cold die parts, large mining equipment parts, etc.
