The ceramic molding process is a production method which guarantees precision, and gives a clean surface finish. It uses a high temperature method to structure and shape parts. This process also gives a low grade of toleration.
The patterns that ceramic mold uses are plaster, plastic, wood, metal, rubber, etc. The pattern is the shape body of the desired part.
History
Ceramic molding has been around for centuries. After man's discovery of fire, man experimented with the process of clay and fire, and began the technique known as ceramic molding, or pottery. Many types of pottery have been discovered by Archeologists, and subsequently linked to the history of the locations they were found. The exact dates and times of certain events have been identified by historians because of the pottery - by examining the pottery and the clay, historians are able to figure out exactly how old artefacts are, and are then able to accurately estimate when an event occurred. Ceramic Molding Is a long owned technique by Neanderthal man.
The process
The ceramic molding process can be summarized in 7 steps:
- Step 1: The pattern is designed with the materials already mentioned (plastic, wood, metal, etc.). Many materials can be used as a pattern because most of them support the low temperature which is used in the Ceramic Molding Process.
- Step 2: The mix is injected into a binder.
- Step 3: Part of some refractory ceramic powder is taken out, according to what is needed.
- Step 4: To the binder, a special gelling is added in order to be mixed.
- Step 5: The slurry is put into the pattern.
- Step 6: The slurry is heated to a high temperature, depending on what is required.
- Step 7: The slurry is allowed to cool and the process is done.
The principal characteristic of the molding process is that it produces very accurate castings.
