A rubber stainer filter extruder, also known as a rubber strainer or rubber filter extrusion machine, is a specialized piece of equipment used in the rubber industry for removing impurities and filtering out foreign particles from rubber compounds before further processing.

The main purpose of a rubber filter extruder is to ensure the quality and purity of the rubber material by removing contaminants such as dirt, metal particles, fibers, and other unwanted substances. It helps to improve the consistency and performance of the rubber compound and prevent defects in the final rubber products.

The construction of a rubber filter extruder is similar to a standard rubber extruder and typically consists of a hopper, feeding mechanism, barrel, screw, die head, and controls. However, it includes additional components and features dedicated to the filtration process.

Inside the barrel of the rubber filter extruder, there is a filtration system that incorporates a mesh screen or filter screen. The rubber material is fed into the hopper and transported by the feeding mechanism into the barrel. 

As the material moves along the barrel, it is forced through the filter screen.

The filter screen is designed with a specific mesh size or configuration to trap and retain unwanted particles while allowing the rubber compound to pass through. The trapped impurities are collected and removed from the extruder periodically or continuously, depending on the design of the machine.

The continuous filtering process in a rubber filter extruder ensures that the rubber compound remains free from contaminants as it is extruded through the die head. This helps to produce high-quality rubber products with improved consistency, performance, and visual appearance.

The specific features and capabilities of a rubber filter extruder may vary depending on the manufacturer and model. The mesh size, filtration capacity, and other parameters can be customized to meet the specific requirements 

of different rubber compounds and application needs.

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.
