摘要:
A method of forming a mold for use in the casting of a steel railway freight car truck component is provided. A cope mold is formed by providing a near net shape oversize impression of a cope pattern of a product to be cast in a flask. A cope pattern of the product to be cast is then placed on the flask forming a spacing between the cope pattern and the oversize impression. A resin coated sand is then blown to form a sand layer between the oversized impression in the flask and the cope pattern. The resin sand is set to form a mold of a thickness between the oversized impression in the flask and the cope pattern of the product to be cast. The drag mold is formed in a similar manner.
