Cosmetics cosmetics packaging hose production mold pultrusion technology important tool, generally consists of two parts, preforming die and forming die.
preforming die: in pultrusion process, after the reinforced material before entering the molding cosmetics cosmetics packaging hose production, must pass a composed of a set of pilot sand component preforming cosmetics cosmetics packaging hose production mold, is the role of preforming mold rubber reinforced material, in accordance with section configuration forms, gradually formed the approximate forming cavity shape and size of preforming body, and then into the forming die, so that products uniform cross-section sand content.
the molding cosmetics cosmetics packaging hose production: cosmetics cosmetics packaging hose production molding mould cross sectional area and the ratio of the cross section area of generally should be greater than or equal to 10, to ensure that the cosmetics cosmetics packaging hose production mold has enough strength and stiffness, after heating uniformity and stability of heat distribution. Pultrusion cosmetics cosmetics packaging hose production mold length is by the forming process of drawing speed and resin gel curing speed, when be being pulled in place to ensure that products reach demoulding curing degree. Generally USES steel plating flipping, cavity surface requirement is bright and clean, wear-resisting, in order to reduce the friction resistance during pultrusion and improve cosmetics cosmetics packaging hose service life of moulds.
