Pouring G eon-based plastisol over master positive metal
pattern—to make a flexible plastic mold.
Flexible plastic
Finished part—produced from low-cost, flexible plastic mold. B. F. Goodrich Chemical Co. does not make this plastic mold. Mye supply the Geon paste resin for the plastisol only.
molds cut design costs -with GEON's help!
MOLDING costs are talcing a new cut—with help from
a plastisol made with Geon paste resin. The plast isol is simply poured over a master positive metal pattern, covering it completely. After cure and cooling, surplus mold material is cleaned from the underside of the model.
The advantages are many. Plastisol makes the process low in cost—ideal for producing limited quanti t ies of par ts where the initial expense of an elaborate metal mold is high. Also, with
a flexible plastic mold, the draw can be in several directions—contrasted to a lead mold with a draw in one single direction. As many as 50 phenolic parts—or 10 to 50 polyester parts can be cast before the plastic mold is discarded.
Geon-based plastisols are used in many ways, offer many advantages. They require no expensive mixing equipment—no solvents— no recovery system, They may be used for molding, casting, coating or dipping. They can be made resistant to heat and cold, aging,
many chemicals. Perhaps they can help you develop or improve products—at lower costs.For helpful technical information, write Dept . GD-9, B. F. G o o d r i c h Chemical Company, Rose Building, Cleveland 15, Orjio. Cable address: Goodchemco. In Canada: Kitchener, Ontario.
