Ceramic mold making opens up endless potential for creative expression.

Ceramic mould making process.

Ceramic mold casting also known ambiguously as ceramic molding is a group of metal casting processes that use ceramics as the mold material. These casting processes are commonly used to make tooling especially drop forging dies but also injection molding dies die casting dies glass molds stamping dies and extrusion dies. The shaw process and the unicast process. Milling raw material procurement the raw materials used in the process are milled materials typically found in mining sites that have been reduced from a large size to smaller sizes or even in some cases pulverized depending upon the end product.

The pores in the mold create a capillary pressure because of this the water in the slip is absorbed by the mold. The process i developed includes sketching using drafting software making models with mdf then making plaster molds from those models. In this excerpt from the march 2019 issue of ceramics monthly jackie head takes you through the plaster mold making process from making a prototype to pouring the plaster mold. It is a combination of plaster mold casting and investment casting.

So have a look and cross learn how to make a plaster mold for slip casting off your to do list. Not only does ceramic mold making enable you to repeat a form over and over again it also makes individual forms lose their preciousness which frees you up to experiment more. Slip casting method is used to produce complex shapes. In this method ceramic particles are suspended in water an cast into porous plater molds.

In order to create these end products the ceramic matter needs to go through the traditional manufacturing process which goes as follows. From simple one piece plaster molds to more complex multi part molds plaster mold making allows the potter the freedom to experiment with ideas for form and surface because it takes away a bit of the preciousness of a one of a kind wheel thrown pot.
