Model XJ-75 XJ-90 XJ-120 Screw Diameter (mm) 75 90 120 Length-to-Diameter Ratio 14:1 14:1 14:1 Motor Power (kW) 37 55 110 Screw Speed (rpm) 55 50 45 Production Capacity (kg/h) 80–120 100–300 300–600 Rubber hoses have a wide range of applications. Fabric-reinforced rubber hoses offer high strength and excellent flexibility, making them suitable for flexible water supply, oil transport, gas delivery, and chemical piping systems. Hebei Shuangda Rubber & Plastics Machinery Co., Ltd. manufactures pin-type cold-feed rubber extruders that feature rapid heating and cooling, precise temperature control, and are equipped with pin-type barrel screws, enhancing material plasticization and mixing performance. When paired with hose dies, water tanks, traction units, winding machines, or cutting devices, these extruders can produce single-layer or double-layer rubber hoses, braided hoses, and more. The entire production line delivers stable performance and high control accuracy. Workflow of the Rubber Hose Extrusion Line 1. Rubber is processed through internal and open mixing. During this stage, raw rubber and additives are thoroughly blended, ensuring consistent quality and an aesthetically pleasing appearance of the final hose. 2. Extrusion by the rubber extruder. The rubber sheet produced in the open mixer is formed into strip-like profiles. These strips are then fed into the rubber extruder to shape the inner tube of the hose, defining its dimensions. 3. Traction—serves to convey and transport the hose. 4. Knitting and braiding. The inner tube, conveyed by the traction unit, passes through a knitting machine where it is braided according to the desired density based on the pressure requirements of the hose. 5. Further traction—similar to step three. 6. Extrusion of the outer layer. Similar to the previous step, the knitted inner tube enters the rubber extruder via a T-shaped die head. The finished rubber hose blank emerges from the opposite side of the die head. 7. Traction and automatic cutting. The finished hose blank is cut automatically to predetermined lengths. 8. Core insertion and shaping. The core is inserted and secured to maintain the hose’s structural integrity. 9. High-pressure vulcanization. The core‑inserted hose is placed into a high-pressure vulcanizing tank for curing. 10. Product removal and core extraction. 11. Final product output.

Rubber pipe has a wide range of uses. Rubber pipe reinforced with fabric has high strength and good flexibility. It is used as a flexible pipeline for water supply, oil transmission, gas supply and chemical pipeline. The pin type cold feeding rubber extruder produced by Hebei Shuangda Rubber and Plastic Machinery Co., Ltd. has the advantages of fast heating and cooling speed, good temperature control system, and equipped with pin type barrel screw, which enhances the plasticizing and mixing properties of materials. Equipped with hose die head, water tank, traction, winding or cutting. Can produce single or double - layer hose, braided pipe and so on. The whole production line has stable performance and high control precision.

Work flow of rubber tube extruder production line

1. The rubber is tightly tempered and opened. At this time, the rubber and auxiliary materials are fully integrated after refining and opening. Make the quality of the hose stable and beautiful.

2. Rubber extruder extrusion. The film has been opened and tempered into strips. Through the extrusion molding of rubber extruder can produce the inner tube of the rubber tube, so that the size of the inner tube of the rubber tube is formed.

3. After traction. Start the transport function.

4. Knitting thread. The inner tube of the hose drawn by the tractor passes through the knitting machine. From the conveyor port to the next link. The knitting density can be adjusted according to the pressure of the hose.

5. Traction. This step is the same as step three.

6. Extrude the outer tube of the rubber hose. This step is similar to the last step. The inner tube of the rubber tube knitted by the knitting machine enters the rubber extruder through the T-shaped head, and out of the other side of the T-shaped head is the wrapped rubber tube blank.

7. Traction transmission and automatic pipe cutting. The length of the finished blank drawn over is set for automatic cutting.

8. Install the core. Core shaping.

9. High pressure curing. Put the cored hose into the high pressure vulcanizing tank for vulcanizing.

10. Remove the core of the product.

11. Produce the finished product.
