INJECTION MOLDING METHOD OF STONE-BASED COMPOSITE MATERIAL AND INJECTION MOLDING EQUIPMENT

摘要

The invention provides an injection molding method of stone-based composite material and equipment thereof, wherein the method comprises the following steps: a. putting raw materials into a charging device and then pushing the raw materials into a preforming machine barrel of a preforming device by a pressing component in the charging device; b. keeping the temperature being between 15°C and 55°C and compacting the raw materials with the rotation of a preforming screw and transporting the raw materials into a collecting block; c. injecting the raw materials into a mold through a mold gate under the injection force of 50 Mpa to 180 Mpa; d. keeping the temperature of the mold between 140°C and 200°C and curing time between 40 seconds and 300 seconds; and e. opening the mold to get the product.
