Common Cold Feed Rubber Extruding Machine_Cold Feed Rubber Extruder

Application of Common Cold Feed Rubber Extruding Machine

cold feed rubber extruding machine is widely used in extruding rubber strip, rubber pipe, inner tube, rubber band, rubber sealing strip.

Our cold feed rubber extruder machine has the following feature: Low energy consumption, high productivity, good mixing quality, even plasticizing.

Common Cold Feed Rubber Extruding Machine Structure Introduction

The machine consists of machine head, extruding system, drive system, heating/cooling system and electrical control system.

Drive system: motor connect to speed reducer high speed shaft through belt.

Speed reducer output shaft drive screw rotation through symmetry shaft key. Screw speed controlled by frequency converter. Users can change machine head mouthpiece and core pattern by themselves according to their preform shape and technology.

Extruding system consists of side press roll feeding device, screw, barrel, bush etc. The machine adopts side press roll compel cold feeding, which enhance output and compaction of preform. The machine suitable to various rubber material-EPDM, NBR & HNBR etc. To achieve high productivity, low consumption, good quality, even preforms.

Machine head,extruding section, plasticizing section temperature control method is by BTW-1210F die temperature controller, for operation detail please reference《die temperarute controller specification》, feeding section and screw cooling by directly import cooling water.

Cold feed rubber extruder is suitable for extrusion molding of rubber tubes, inner tubes, tire tread, sealing strips and various kinds of other rubber products.

The extruded products have the characteristics of good mixing quality and uniform plasticization.

Pin barrel cold feed rubber extruder has not only made significant improvements in screw structure, but also added pins to teh barrel. It has the characteristics of better plasticization performance, low rubber discharge temperature, and large extrusion volume, and has been increaslingly widely used in rubber industry production.

According to customers' requirements, different types machine head can also be customized. By changing machine head, different shape rubber products can be produced.

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.
