Isostatic pressing is our specialty and is used where the size,
shape or batch size of components makes dry pressing impracticable
or uneconomical. We have a wide range of isostatic mandrels
available, offering customers economic manufacture of standard
tubular forms, plates, etc. Grinding, lapping, polishing & honing
are carried out using diamond abrasives. These techniques are used
to obtain tight control of dimensions and surface finishes.
1.Wear-resistant material for surfaces of delivery equipment such
as Chutes / Hoppers, Cyclone separators,Elbows, Cyclones, Convey or
pulleys.
2.Wear-resistant material for liquid flowing pipes of petroleum,
mining, steel ,power
3.Anti-corrosion from chemical substances
4.Thermal impact
Tiling will ensure significant savings on equipment and labour by supplying
innovative solutions. Our products are used extensively wherever
material wear due to abrasion, impact, friction, heat or corrosion.
1. High heat resistance : Alumina ceramic has excellent thermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
2. Good wear resistance : Alumina eramic is the material of choice
for wear parts.
3. High corrosion resistance : It is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.
Alumina ceramic is the most mature of the engineering ceramics,
offering excellent electrical insulation properties together with
high hardness and good wear resistance,but relatively low strength
and fracture toughness.Alumina ceramics are generally white but may
also be pink or ivory.The color is derived from either the
sintering additives or impurities in the raw materials.
