New rubber mixing workshop equipped with advanced machines and mixing technology was built, significantly improving the quality and output of rubber compounds. In order to guarantee the quality, the black rubber compounds are processed separately with the colored ones. Each process needs to be strictly inspected. Only after passing the inspection, next process can be then carried out.

  • Rubber Mixing Workshop
  • Black Rubber Compound
  • Colored Rubber Compound
  • Pallet of Finished Compound

The rubber compounds in each batch will be strictly tested before using. Zebung is equipped with various oil hose testing machines to carry out tests including tensile, twisting, bending.


We have several automatic production lines for processing rubber hoses with diameter ranging from 6mm to 1150mm to meet various customer needs.

Workshop overview in 2015

1. Raw Materials

The raw materials for our hoses include natural rubber imported from Thailand and nitrile butadiene rubber (NBR) from South Korea. Both materials are chosen because of their high temperature resistance.

2. Mixing Process

The mixing process includes batching, mixing, cutting, etc.
A rubber mixing mill is used for batching and pressing raw materials.
A Calender machine is used for calendering and forming the rubber.

  • The rubber, after being pressed, will be cut into the required sizes and then rolled tinto semi-finished products.
  • Semi-finished Products Area
3. Rubber Slitter

The rubber slitter is used for cutting the hose according to the required diameter. It can use 10 knives together to cut rubber hoses.

The material is cut by the rubber slitter
4. Extruder

The extruder has two steps, the first step is extruding the hose core, and the second step is extruding the braided hose.
The rubber hose has a uniform wall thickness, and features anti-aging and wear resistance.
The braided hose is heated by chloride rubber and extruded rubber.

5. Braiding Machine

We have 7 high speed braiding machines and 7 common braiding machines. The production capacity of the high speed braiding machine is 1000m/day, the common braiding machine is 300m/day.

The 24 spindle cotton braiding machine is used to braid polyester yarn on nylon hose. The inner diameter of the hose is 6mm-25mm.

6. 60m Automatic Industrial Hose Production Line

Our company has imported 2 60 m automatic industrial hose production lines from Italy.

  • 60m VP Industrial Hose Production Line
  • The density of the hose is uniform. The strength of the adhesion is strong between wire and wire, wire and rubber.
  • Rubber Winding
  • Wire Winding
7. Food Grade Hose Production Line
8. Marine Hose Production Line

We independently designed and developed this large diameter hose production line. The maximum range of the inner diameter of the hoses is 6-36 inches, the length is 0.5-8m. We can manufacture SPM, CALM, SALM, MBM, and Tandem Mooring series oil hoses.

9. Vulcanizer

The vulcanizer is used for heating and curing of hoses using steam. This is the final step of making hoses. We use large vulcanizers with diameters of 1m, 1.5m, and 3m, their length can reach 60m.

10. Finished Products Area

The finished products area is used for storing various specifications of packaged hoses.

  • Floating Hose, One End Reinforced Half Floating

    One end reinforced half floating hose is used for connecting with the single point mooring buoy system or CALM (catenary anchor leg mooring) buoy system to transport crude oil and petroleum fluids between FPSO and tanker.
  • Submarine Hose without Float Collars

    Designed without float collars, the submarine hose is suitable for use in connecting with subsea manifolds, and main submarine pipelines fitted in the hose strings on the single buoy mooring system.
  • Dock Hose, Marine Oil Hose

    The dock hose is a multi-purpose hose product specially designed for suction and discharge applications. This suction and discharge hose is suitable for connecting with tankers, barges, storage tanks, etc. to transfer petroleum product.
