[ Rubber & Tire Machinery ]

Next-generation mixers play an important role in the rubber and tire industry.
The demand for high quality and high performance of various rubber products including but not limited to automobile tires is becoming higher and higher. The mixing process is the critical process that greatly affects the final quality of rubber and tire products. Thus, Mitsubishi Heavy Industries Machinery Systems provides various rubber mixers complying with the customers' needs.
Mitsubishi internal mixers including NM series (Neo Meler), a new generation mixer, and MR series, with a long successful record, respond to a wide variety of needs by achieving innovative mixing performance.
Variety of mixing rotors is available depending upon the usage and characteristic of mixing compounds.

Features of the MR series

Intermeshing rotor system

MR-E series Internal Mixer equips with intermeshing type rotor which has a unique wing contour different from that of conventional rotors. This mixer provides with high quality, high productivity, high durability, and low maintenance required in today's rubber industry. This series shows excellent mixing performance in heavy load mixing operation of soft to hard compounds.
MR-EX series Internal Mixer is an innovative mixer that was developed for the silica impregnated compounds.
Tandem mixing system is also available, in which production size mixer is positioned at the upper side and larger size one is at the lower side.

Tangential rotor system

MMR-X series Internal Mixer equips with a tangential type rotor widely used mainly in the tire industry as a basic model. MR-X series developed based on long experiences includes various rotor wing contours that can be selected depending on the mixer application from the mastication to the final batch, responding to mixing needs for many purposes.

Features of the NM series

Intermeshing rotor system

NM series (Neo Meler) is now a focus of attention especially in the industrial rubber goods industry as a new generation kneader. The Neo Meler with an intermeshing type rotor developed exclusively for the MR-E series mixer has been drastically improved in the mixing performance to the extent that no conventional kneaders have ever achieved. As a kneader, it also has a compact structure and excellent maintainability.

Various test mixing facilities are prepared in our development center for the customers' convenience to check/confirm the mixing performance of our internal mixers.
