Profile foundry sand box is automatic, semi-automatic molding line of necessary technology and equipment, with professional technology and equipment production and testing to ensure high precision sand box, interchangeable. Ductile iron, high-grade gray cast iron or carbon steel plate welding, with good rigidity and impact resistance, high pressure, etc., users can design and manufacture a variety of standardized molding box, cavity size and shape is determined by the user. Widely used in foundry casting the entire casting mold sand box, such casting mold sand box is characterized by high strength, rigidity, low cost, easy to use. Prayer of the technical requirements of the entire casting mold sand box is divided into two aspects of the casting mold sand box blank and processing of technical requirements. The maximum deformation of the side wall of the high-pressure molding box allowed: high-pressure molding, sand box sales, sand box side wall under a lot of pressure on the side, the side effect of pressure causes deformation of the side wall of the flask, especially when there is no box belt, Deformation more serious. Therefore, sand box, sand box must have sufficient strength and rigidity, in use should not be plastically deformed. Elastic deformation should be restricted. This is because as the pressure load is removed in a state of elastic deformation of the walls of the box are also removed with force inward bounce.
