When it comes to quality casting at a reasonable price, Karoway can help you every step of the way. Whether you provide the original model yourself or have one of our talented model makers produce a model according to your specifications, you can be sure that the resulting castings will meet your needs. We offer both Tin-Lead and Lead-Free casting alloys.

The casting process begins by "sinking" the original model into a rubber disc mold. This mold becomes the master mold and is used to cast enough copies of the original model to create a production mold. The number of cast copies required depends on the size of the piece and amount of space needed between the pieces so that they will then cast properly during production. The size of the cast pieces also dictate how thick the production mold will be and the diameter of the mold. Karoway is capable of making production molds as large as 18" in diameter with a thickness of up to 3".

Once all of the pieces are positioned in the production mold, the mold is vulcanized using heat and pressure. This process forces the mold rubber into every void, capturing all of the detail and surface texture of your original model. Vulcanization also "cures" the rubber, making it firmer and more durable, capable of producing many, many identical copies of your original model.

Once the production mold has been completed, it is placed into the centrifugal casting machine. The casting machine is turned on, spinning the mold at a high rate of speed. Molten metal is then poured into the center of the mold and centrifugal force pushes the metal into the cavities inside the mold. Once the mold cools, it is removed from the casting machine and the two halves of the mold are pulled apart, exposing the cast pieces. The cast pieces are then separated from one another and finished according to the needs of the customer.
