Industrial Ceramics Slip Casting Process

The Slip-casting process involves using a “slip” which is a suspension of fine ceramic material powders in a liquid such as water or alcohol with small amounts of secondary materials such as dispersants, and binders. This material is poured into a mould which is typically made from Plaster. The mould is created from a wooden former so it is easy to reproduce a number of casting moulds. The plaster mould draws water from the poured slip to compact and form the casting at the mould surface. This dries to form a dense part removing deleterious air gaps and controlling shrinkage. Once the part is formed it is sintered to produce the finished product.

The slip casting process has a number of advantages and disadvantages associated but can be cost effective under the right conditions as a method of manufacture.

Some of these advantages include a low tooling and set up cost and it is a very simple method of production. Another sizable benefit being no expensive equipment is required (until…
