摘要：PROBLEM TO BE SOLVED: To provide a method for manufacturing a high-strength plate mass- shaped artificial stone which shows a beautiful surface appearance and can be easily worked after molding, on account of a non-gel coat technique of a casting process and a joining method by which the joint borderline between the obtained artificial stones is not conspicuous. SOLUTION: The method for manufacturing an artificial stone comprises the first step to add a specified amount of granular pattern-exposed material 12 forming a grained pattern to a matrix 11 composed mainly of a fine- powdered inorganic filler, a curing agent, a curing promoter and a small quantity of colored pigment to an unsaturated polyester resin and remove bubbles from the materials while the material are stirred/mixed using a mixer to obtain a base compound with a proper fluidity, the second step to inject the base compound into a frame 21 and let it be cured at a normal temperature to obtain a primary cured form 22 and the third step to release the primary cured form 22 from the frame 21, then load it into a thermal treatment device and thermally cure to obtain the artificial stone 10.
