Production of sink with Plaster Molds

Plaster molds are a common method in the production of sinks in the vitreous china industry. This process primarily requires the creation of a design and a model. This model is used for the creation of the plaster mold, and plaster is poured over the model and left to harden.

During the casting process, liquid ceramic slurry is poured into the plaster mold. The plaster absorbs water from the ceramic slurry, allowing the walls of the sink to reach a certain thickness. This hardening process helps to form the shape of the sink.

The sink removed from the mold is then dried and fired. The firing process hardens the sink and makes it waterproof. In the final stage, the sink is glazed in various colors and patterns and fired again. This process creates a glossy and durable surface.

Sink production with plaster molds allows for the creation of detailed and complex designs, which is one of the reasons why this method is popular in the vitreous china industry.
