PIN BARREL COLD FEED RUBBER EXTRUDER

1 Different extrusion heads are applied to extrude various half-finished rubber products. Straight head, Tread head, Cross head, Strip Extrusion head and Strainer head all can be used to the machine.

2 The barrel is composed of several zones. In the feeding zong, the spiral slots work with the side rolls to enhance feeding capability. 

In the plastication and extrusion zones,different numbers of pins are fitted. The barrel is of the dual metal structure and bored circumferentially.

3 The screw material adopts 38CrMOALA alloy steel, after quenching and tempering, shaping, qualitative, precision grinding, surface nitriding spray bimetal, polishing, etc., with the feature of high precision, high corrosion preventive, high weart resistant. The screw service life is double prolonged.

4 The gears in the hard teeth reducer are made of alloy steel,the teeth are very hard.

Gearbox with hollow output shaft for screw cooling though Rotary Joint.

5 Heating and cooling system:die heater(mold temperature controler). 

6 Constant Speed or Variable speed drive as per specific requirement.

Motor: frequency speed control motor or DC motor.

7 The advantages of the machine include better plastication result, higher extrusion capability, lower temperature of the outgoing rubber and smooth working, easy operation and maintenance.

8 It’s widely used in extruding rubber hose, rubber tubes, rubber sheet, inner liner, seals, wire cable, sheath, tire tread, tire side wall, also be used to supply rubber for small size calender.  

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.

Temper Degree：HB240°～280°

Nitriding Hardness：HV850°～1000°

Nitriding Deepness：0.45～0.7mm

Nitriding Brittleness：≤Grade Ⅱ

Surface Roughness：Ra0.4

Screw Straightness：0.015mm

Hard Chrome Plating after Nitriding：≥900HV

Chrome Thickness：0.05～0.10mm

Two-phase Alloys：HRC56°～65°（nickel-base alloy）

Alloy Deepness：1.5～2.0mm

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.

Normal Models (Pin Barrel Vacuum Cold Feed Rubber Extruder) for Choice:

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.
