Unformatted text preview: Spin Casting A variation on the opaque silicone RTV rubber process is available from Tekcast
industries, Inc.6 The tools generated in this process are made from vulcanized
rubber, with several models located radially in a disc-shaped tool. When the tool
is produced, it is possible to cast polyurethane or zinc—based alloys. To aid filling,
the tool is rotated so that centrifugal force pressurizes the cavity. This is an excel- lent process for forming small zinc castings that will be ultimately manufactured
in large quantities by die casting. '1; am: 01 mm m}
