Slip Casting
For Sanitary ware manufacturing there are four basic types of casting techniques
1. Capillary Casting in Plaster Moulds
2. Bench Plaster Mould Casting
3. Battery Casting in Plaster Moulds
4. Pressure Casting in Polymer Moulds
Capillary Casting in Plaster Moulds
Capillary Casting is comparatively better in terms of profitability when compared to Bench and Battery Casting as, the same mould […]

Slip Casting
Instead of plaster, the moulds are made of polymeric materials: while porous, these have larger pores that do not generate the same capillary forces but require an externally applied pressure to drive the filtration process. However, the application of much higher pressure (

Slip Casting
Advantages of slip Casting method
1. Complex objects can be easily and well shaped.
2. As the mould material cheap, this method is a very cheap shaping method.
3. Good Material Homogeneity can be achieved.
Disadvantages of slip Casting method
1. Requirement of large number of moulds for large scale production.
2. Space necessity for mould placement
3. Limited life time […]

Slip Casting
This method is for manufacturing powder based ceramic components like tableware and sanitary ware. However this method is also used for manufacturing advanced ceramic products too. Slip Casting is a filtration process. In this process a powder suspension (a water-based suspension) is poured into a plaster mould, which by its porosity creates […]

Slip Casting
Most moulds can have a reservoir built onto the filling hole to automatically feed more slip as the level drops. After this the surplus slip is tipped out and the moulds are allowed to drain while the clay body dries. This could take anything from an hour or so to a couple […]

Slip Casting
The Plaster mould is made by solidifying the plaster of paris around the original mould and then cut in half to leave a hollow section of the required shape. These two halves are then held together with rubber bands or tensioned string etc. These plaster moulds can last only for fifty casting […]

Slip Casting
Slip Casting is the most widely used Ceramic Shaping Technique for manufacturing Ceramic Products. This process involves introducing the slip (Clay +Water mixture) into a mould and then removing the mould to get the shaped product. Though this process may seem simple in words, they are not so in real industrial scenario. […]

Extrusion Shaping
The relationship between the extrusion pressure needed to extrude a certain material with a certain extrusion mouth as a function of the extrusion rate is dependent on the minimum pressure characteristics of the body and the characteristics of the extrusion mouth. Variations in pressure caused by changes in the extrusion rate are […]

Extrusion Shaping
A constant-thickness die generally ensures good equilibrium of the forces in play during the extrusion process. The lower the body moisture content the higher the plastic body attrition forces; it is thus easily understandable that, whatever the other parameters of the extrusion process described above, that the water contained in the ceramic […]

Extrusion Shaping
The material is fed into the propulsion system feed zone. The propeller exerts a dragging, compaction and compression action on the de-gassed plastic mass. Between the end of the propeller and the extrusion mouth there is a zone without any mechanical parts; here, the plastic body being fed by the rotary propeller […]
