Hose production processes for the rubber compound processing, cord and canvas processing, hose forming, curing, etc.. Different structures and different skeleton, a hose, a processing method of the skeleton layer and hose molding apparatus varies. Full rubber hose without skeleton layer, simply use the extruder pressure of the hose can; fabric hose need to use the tape included adhesive layer on the molding machine; suction hose wrapped around the metal spiral molding required After the package glue; Weaving and winding hose knitted hose need to use a special fabric weaving machines or winding machine; need to use a knitting machine. Hose molding method whether to die, to be divided into the the coreless law, and core law (including the the soft the cores law and hard-core law). Coreless molding: hose coreless molding, the device is an extrusion molding machine (common screw extruder), and a skeleton layer and the outer layer is directly molded on the pressed out of the inner hose. Plastic material by means of extruder screw placement in the machine barrel, stirring, mixing, plasticizing and pressed, and then moved to the head direction, and finally extruded from the mouth of a certain shape of the product, the screw extruder stars hot feed and cold feed two, the former feeding material preheating after open-roll bars, the latter feeding without thermal refining rubber. http://www.jinshuruanguanchang.com
