Bharaj Machineries - Manufacturer of Cold Feed Rubber Extruders in Mumbai, India.

Power Your Production with our Cold Feed Rubber Extruders

Bharaj Machineries has been a trusted name in industrial rubber processing equipment, delivering high-performance machinery built for durability, efficiency, and consistent output. Our range of rubber extruder machines is engineered to meet the diverse demands of industries such as automotive, construction, firefighting equipment, LPG hose manufacturing, and more.

What Is A Cold Feed Rubber Extruder?

A cold feed rubber extruder is an advanced industrial machine that processes raw rubber compounds at room temperature, eliminating the need for a warming mill before feeding the material. This not only saves significant energy but also reduces labour costs and simplifies the production workflow. Unlike traditional hot feed systems, our cold feed rubber extruder machines feed rubber directly into the screw mechanism through a specially designed hopper with a spiral undercut and feed roll arrangement, ensuring proper bite and consistent strip feed every single time.

This makes Bharaj Machineries one of the most preferred rubber extruder manufacturers for clients who demand precision, power, and reliability in their production lines.
