    6 days ago · Because plaster of Paris sets quickly, "retardants" were used to slow setting time enough to allow workers to mix large working quantities of lime putty plaster. A modern form of this method uses expanded metal mesh over wood or metal structures, which allows a great freedom of design as it is adaptable to both simple and compound curves.

    6 days ago · The main use of calcium sulfate is to produce plaster of Paris and stucco. These applications exploit the fact that calcium sulfate which has been powdered and calcined forms a moldable paste upon hydration and hardens as crystalline calcium sulfate dihydrate.

    Plaster mold casting, sometimes just called plaster casting, uses a mixture of gypsum, strengthening compounds, and water to create a mold. The plaster used is not pure plaster of Paris. Instead, it has additives that improve green strength, dry strength, permeability, and castability. For example, talc or magnesium oxide are often added to prevent cracking and reduce setting time. The plaster pattern is made of metal or sometimes rubber and is typically coated with an anti-adhesive compound to prevent it from becoming stuck against the mold. If the casting includes reentrant angles, an interior angle that is greater than 180°, or complex angular surfaces, then a rubber mold is flexible enough to be removed, unlike metal. These molds are also inexpensive, fast to create, reusable, more accurate than steel molds, and easy to change. Plaster fills in any gaps around the mold. Once the plaster material has been used to cast a part, it usually cracks or forms defects, requiring it to be...

    Plaster casting fabricates products with a very smooth surface finish, allows for the casting of complex shapes with thin walls, can form large parts with less expense than other processes, such as investment casting, and has a higher degree of dimensional accuracy than that of sand casting. The major disadvantage of plaster mold casting is that it can only be used with lower melting temperature non-ferrous materials, such as aluminum, zinc, magnesium, and sometimes copper alloys. The most common plaster cast material is aluminum. The maximum working temperature of plaster is 1,200 °C (2,200 °F), so if a metal needs to be heated at a higher temperature to melt, it cannot be plaster cast. The reason only non-ferrous metals can be used is that sulfur in the gypsum reacts with iron. Another disadvantage is that the longer cooling times can restrict production volume. Plaster mold casting is often used to make lock components, gears, valves, ornaments, fittings, and toolings. It is also...
