Information : Short-run Tooling
Standard has developed "slush tooling," a unique mold construction technique used for short production run potting applications. This technique has worked well with Standard's practice of producing short runs of many different types of items.
Hard tooling is made from machined aluminum in the required mold shape. When needed, the aluminum tool is dipped in a special low melting temperature alloy and coated. The material cools rapidly and expands slightly, making removal of the solidified alloy shell from the tool relatively easy. The alloy shell is then used as the mold for the potting operation. If the aluminum tool is cooled after repeated use, an unlimited number of molds can be produced. The alloy mold is melted and recycled if it is damaged or no longer needed.
