High-pressure hose production process

Dongying Guangyou Rubber Co.,Ltd | Updated: Mar 04, 2016

1.with the mixer according to the formulation of the inner plastic mixing, middle and outer plastic glue; extruder with inner tubing, covered in soft core coated with a release agent or hard core (liquid nitrogen freezing also not die)

2.the middle rubber calender pressed into thin slices, add the release agent winding according to process requirements cut into a predetermined width

3.containing the die inner tubing on the wound or braided copper wire or copper wire rope winding machine or on a knitting machine, while the winding machine or knitting machine will synchronize the middle plastic sheet copper wire wound around every two or copper inter rope, winding wire beginning and end of lashing (some early winding machine will be pre-processed copper wire prestressed stereotypes)

4. again in the extruder coating on the outer layer of plastic, then wrapped curing protective layer of lead or cloth

5. through the autoclave or salt bath vulcanization

6. finally remove the sulfide protective layer, out of the die, to withhold fittings, sampling to suppress the test.

    In short, the use of high-pressure pipeline manufacturing equipment and more, many kinds of raw materials, production process complicated. But in recent years with plastic or thermoplastic elastomer as the main raw material of hydraulic tubing production process can be appropriately simplified, but raw material prices, the main raw materials is still rubber.
