Design Guide

SIZE AND WEIGHT
Part size and weight are the most critical factor in determining investment casting cost because mold capacity is limited by both size and weight. The more pieces that can run on a mold, the lower the part cost. Unnecessary mass should always be removed by correct engineering practices to reduce part weight.
 
NUMBER OF GATES
When possible, a part should be designed so that a single gate can feed the part. This will generally yield more pieces per mold and reduce the pour weight per mold.
   
CASTABILITY
The design contains features that will raise scrap or rework rates (and piece price) the Signicast Estimating Engineer will recommend design modifications to keep the piece price down.
