1. Hot Feed Rubber Extruder Usage
Rubber extruder is mainly used for shaping and extruding various shape rubber products, hot feed rubber extruder normally works after an open rubber mixing mill. such as tyre tread in tire production.
Hot feed rubber extruder can be used for shaping and extrusion of various shape rubber products such as rubber pipes, rubber rods, rubber sheets, rubber tyre tread.
Hot feed rubber extruder can also be used for Continuous coating of rubber wires, rubber cables, rubber hoses and other rubber extruding products.
The hot feeding rubber extruder requires that the rubber material fed must undergo heat refining, and the feeding should be uniform, stable, and at a constant speed, with the material temperature maintained at 50-70 ℃.
The screw of the hot feed rubber extruder is short, the thread groove is deep, the homogenization effect is average.
Normally hot feed rubber extruder is also used follow an open rubber mixing mill, which is for press rubber sheet.
2. Equipment composition
Hot feed rubber extruder is mainly composed of screws, barrel, feeding device, gearbox, mechanical (hydraulic) head, machine base, motor and electrical control system.
If necessary, a temperature control system can also be configured, and the motor can be a AC (or DC motor for choice) motor.
3. Main performance parameters
Our company can provide users with a full range of hot feed rubber extruders with screw diameters ranging from φ45 to φ300 and screw L/C ratios ranging from 4.4 to 8.

Control Panel, which is movable on extruder machine, so it's easy for worker to operate in any position around our extruder machine,
and we can put your language beside the buttons.
Control Box, our rubber extruding machine use high quality electronics, ensures the machine working sensitive and reliable.
The speed adjustment is very smooth and stepless.
Motor, according to machine model and work, there are AC motor and DC motor two kinds to our rubber extruding machine.
Our extruder machine adopts copper wire motor, which have good conductivity, low resistivity, and can achieve larger output power at smaller currents, thereby reducing electrical energy loss. Good corrosion resistance.
Copper wire motors are less prone to rusting and have a longer service life.
Excellent reliability. The connection points and joints of copper wire motors are easy to solder and connect, thus having higher reliability.
More durable.
The durability of copper wire motors is better than that of aluminum wire motors, because aluminum wire has a higher resistance than copper wire and generates higher heat during use, which can easily burn out the motor.
More energy-efficient, copper wire motors have a smaller resistance and lower heat generation, making them more energy-efficient.
More silent, copper wire motors used in our rubber vulcanizing press machine have less noise because aluminum wire motors have a noise level approximately 7 decibels higher than copper wire motors.
Mold, good parts makes good machine, but it also need a good design. We are just the maker which can provide you a perfect proposal according to your detail work needs.
Drawing just for Reference, if you want us make extruding mold for you, please send us your drawings or samples.
The equipment models and production processes used in the production of different rubber products are also different. Some rubber products require vacuum pumping during production, while others require the use of pin type rubber extruders during production. In addition, some products belong to single extrusion products, while others require the use of composite rubber extruders for extrusion production. The molding equipment and auxiliary equipment used in the production of different rubber products need to be selected based on the actual needs of the products.
Just contact and tell us your work needs, we'll provide you a suitable proposal, high quality hot feed rubber extruder with most reasonable price.
