Industrial Tooling Plaster

When Performance Rests on the Quality of Your Operation
Uniform texture and densities ensure that our tooling plasters adhere to the exacting specifications demanded by leading manufacturers. Industrial tooling plaster products attain and hold close tolerances, with expansion controlled to 0.0003 in./in. Stability is also critical. Our products will not warp or shrink under normal temperature and humidity ranges. Their excellent adaptability makes tooling plasters ideal for the most intricate and complex designs. In addition, our product provides a surprising cost effectiveness. Gypsum cements require just one-third to one-half the time of standard tooling techniques.
Produced from some of the world's purest gypsum, Georgia-Pacific industrial gypsum is manufactured from exceptional raw materials, up to 99%+ pure, in carefully controlled conditions. Chances are one of our industrial plaster products features the exact formulation that meets your requirements. If not, we will gladly customize a special formulation based on your specifications.

Industrial Molding Print Spec Every shop needs to have a good utility plaster on hand. Industrial Molding Plaster fills the bill, with all the reliability you would expect. Recommended for applications without stringent requirements for surface hardness, strength and expansion control. It is excellent for waste molds and temporary tooling. 70 - 75 27 - 37 0.15 65 - 69 1500 - 2000
Three main techniques are commonly employed when gypsum cements are used in industrial tooling: pouring, screeding and splash casting. The adaptability of Densite and Denscal gypsum cements make them well suited to these methods, which are explained below:
Straight-Run Molding Technique
Produces a pattern or model with parallel sides
Uses a flat bench with at least one straight edge, a screeding tool and a metal template cut to the desired configuration
Screeding tool is pushed through the gypsum cement mixture, forming it to the contour of the metal template
Circular Molding
Modification of the straight-run molding technique
Employs a template rotating around a center pin
Produces a symmetrical pattern such as a disc, wheel or housing
Box-Turning Molding
Commonly used for making cylindrical and cone-shaped models and patterns
Utilizes a wooden box assembly with a metal template secured to an open top
Non-pourable mix of gypsum cement is anchored to a central turning rod, which is rotated to shape the gypsum cement to the contour of the template
Loft-Template Molding
Ideally suited to production of non-symmetrical shapes
Commonly used to construct master models, original patterns and prototypes
Contour lines are copied onto rigid steel of aluminum sheets to make templates, which are mounted on a rigid base
Gypsum cement mixture screeded to form a smooth, close-tolerance surface
Splash Casting
Used in applications requiring large irregular shapes that are not readily adaptable to pouring
Layers of gypsum cement mix and half-inch fiber bats placed over the surface to produce a one- to two-inch uniform cast of a pattern or model
