CUMI manufactures a great variety of products with silicon carbide ceramics build to withstand extremely harsh environments with outstanding performance.

CUMI engineered ceramics’ excellent electrical insulation & hermetic sealing (leak tight joints) makes them suitable for use in vacuum interrupters in vacuum circuit breakers. The dielectric nature of ceramics also enables them to be used as capacitors.
Ceramics are preferred over various other materials exhibiting electrical insulation property e.g. rubber, plastic, wood etc. due to their excellent wear and thermal resistance.

Extreme Wear resistant solutions from CUMI Ceramics. Molten metal handling applications in metallurgy processes require extremely high thermal shock resistance, low thermal conductivity and non-wettability properties. Our CUMITHERM™(for non-ferrous) & CUMITHERM-Z ™( for ferrous) formulations have been designed to suit for high temperature molten metal environments in cast-houses and foundries. These properties are achieved by combining High purity alumina and titania in a precision controlled reaction-sintered process to engineer a microporous microstructure.

During the bulk material transfer, the equipment/machinery interacts with a broad spectrum of grain sizes ranging from big lumps to fine dust size particles. Wear is thus caused both by the abrasive action of finer particles & impact force by lumps.
Catering for the twin requirement of wear and impact, Wear resistant Alumina is combined with impact resistant Rubber. This material combination acts as a perfect solution for bulk material conveyance applications.
Our CUMI-RBC (Rubber backed ceramics) formulation has been specifically designed to cater for wear & impact prone environments. Some of the application areas are as mentioned below:

Wear and corrosion together make a lethal combination for equipment and machineries. Corrosion is facilitated by the presence of moisture and it accelerates the wear phenomenon. For industries which use chemicals or are exposed to moisture are vulnerable to be affected by corrosion.
Our CUMITUFF CSP formulation has been specifically designed to cater for wear & corrosive environments.

The constant interactions between surfaces and subsequent removal and deformation of material from a surface can be termed as Wear. It is a destructive phenomenon which reduces the useful life of machines & components. Wear is a phenomenon experienced by almost all the manufacturing industries but the severity of wear differs based on the operating procedures and operating disciplines. Abrasive material movement experienced in the Coal washery, Power, Cement, Steel, Minerals & Metallurgy industries makes them extremely vulnerable to wear.

Another worry for industries dealing with abrasive environments is corrosion. Corrosion is facilitated by the presence of moisture and it accelerates the wear phenomenon. Wear and corrosion together makes a lethal combination for equipment and machinery. For industries which use chemicals or are exposed to moisture are vulnerable to be affected by corrosion.
Our CUMITUFF CSP formulation has been specifically designed to cater for wear & corrosive environments. Our CUMITUFF range of wear resistant ceramic tiles comprising of standard and customized pre-engineered tiles cover complete spectrum of wear-resistant solutions for a variety of applications.

CUMI also offers a range of pre-fabricated ceramic lined equipment which are advantageous in situations where the geometry is complex or shutdown/installation time is small.

CUMITUFF® high alumina ceramic tiles are manufactured from 90% and 92% alumina for wear resistant applications particularly for Steel, Cement, Power, Coal washeries & Mineral handling Industries and also other similar applications where corrosive attack is severe. CUMI’s Ceramic tiles have shown excellent performance in extremely abrasive & Corrosive environments where our competitor’s tiles could not withstand for even 1/10th of CUMI’s high alumina Ceramic tiles’ life. Our materials conform to rigorous laboratory testing to maintain excellent surface finish under the effects of various reagents/chemicals.
