Large adopt resin sand resin sand casting, mold casting, sheet 40 tons, annual output around 8500 tons. Including the bed, table, column, longmen, connecting beam. Material are of high quality of grey cast iron HT200 - HT300, precision ratio, higher tensile and bending strength, make you buy no worries. The international popular heat treatment process, reduce the deformation and stress of the casting to the smallest degree. Used for a long time tend to be more stable.
Resin sand casting is a general designation, in front of the modelling, the core sand on the surface has been covered with a layer of solid resin membrane sand , known as the core sand coated sand, also known as the shell mold (core) sand.
Resin sand casting is the original sand and resin blend to form the resin sand, resin sand into the mold cavity, by heat or catalyst method makes its forming, after forming the palatial core in the casting mould in the casting.
Resin sand casting with a small surface roughness, high dimensional accuracy, good quality characteristics.
