Production Process of High Pressure Rubber Hose
All our high pressure rubber hose are produced through strict quality controlling system. Here, we will introduce you the whole production process to let you know more about the high pressure rubber hose and our company.
Step 1: Extrude inner rubber – smooth surface and uniform thickness.
Step 2: Air drying – keep the hose dry.
Extrude inner rubber.
Step 3: Reinforcement layer production – braided or spiral process.
Step 4: Extrude rubber cover and stick label – protect hydraulic hose from corrosion and abrasion.
Step 5: Wrap water cloth – protect the hose in vulcanizing process.

Warp water hose.
Step 6: Vulcanize – direct steam heating of vulcanizing boiler or continuous vulcanizing.
Step 7: Remove water cloth – separate the water cloth and hose after vulcanization.
Step 8: Demould by water pressure.
Remove water cloth.
Step 9: Test pressure – test the working pressure and burst pressure.
Step 10: Size test and package – measure lengths of rubber hoses and packed them with packing belt.
