또, 이와 같은 인공대리석은 상기 성형재료를 압출성형기의 압출다이로 부터 소정 형상으로 압출한 직후 냉각 재킷이 부착된 포밍다이에 도통시켜 고화상태로 성형하는 공정을 포함하는 제조방법에 있어서, 상기 압출기에 의한 압출온도를 180-220℃, 상기 포밍다이에 의한 성형체의 냉각온도를 150℃이하로 설정함에 따라 적절하게 제조할 수 있다.In addition, the artificial marble is a manufacturing method comprising the step of molding the molding material in a solidified state by conducting to the forming die with a cooling jacket immediately after extruding the molding material from the extrusion die of the extrusion molding machine. By setting the extrusion temperature by 180-220 ° C and the cooling temperature of the molded body by the forming die to 150 ° C or less, it can be appropriately produced.
