High pressure hose production process: 1, with the mixer by mixing the inner plastic formulations, middle and outer plastic glue; extruder with inner tubing, coated in soft-core coated with a release agent or Hard core (liquid nitrogen freezing method can also be not die) 2, calender pressed into the middle of plastic sheets vapor pressure hose, plus press release agent rewinding process requirements cut into a predetermined width 3, inner tubing containing die in wound on the winding machine or knitting machine copper wire or copper wire rope high pressure hose, while the winding machine or knitting machine will synchronize the middle plastic sheets wrapped in copper wire between every two or copper wire rope, wire wrapping beginning and end of the lashing (Some early winding machine will be pre-processed copper wire prestressed stereotypes) 4, again in the extruder, rubber-coated outer layer, then wrapped a protective layer of lead sulfide or cloth 5, or by autoclave curing salt bath 6, finally remove sulfide protective layer, out of the die, withholding on fittings, pressure test sample. In short, the use of high-pressure tubing manufacturing equipment and more, many kinds of raw oil pressure hose, complex production process. But in recent years, plastic or thermoplastic elastomer as the main raw material of hydraulic tubing may be appropriate to simplify the production process, but raw material prices, raw rubber is still based. Coreless molding screw extruder part sectional view of the hose coreless molding, extrusion molding machine equipment (commonly screw extruder), the skeleton layer and outer layer formed directly on the pressure inside the hose. With rubber extrusion screw is placed in the barrel stirring, mixing, plasticizing and compression, and then moved to the head direction, the final product from the mine mouth shaped extruded using a high pressure hose, a screw extruder Heat and cold feed and feed two, the former is fed through the open roll preheated strip, which is fed without soak plastic material.
