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. This process needs in-depth technical knowledge and process understanding for being functional in industries.
Following are the process steps followed in the Slip Casting Process. First a solid model of the article to be manufactured is made. This model is generally made out of solid clay or plastercine or acrylic. This model is always oversized than the original article to allow for the shrinkage losses during process.
