We typically deal with materials ranging in thickness from .015″ to .500″. • What types of tooling are used in thermoforming? Three types of tooling are commonly used: a) Machined Aluminum Molds Machined aluminum molds are usually done on CNC machines from generated CAD files and can be either male or female. Typically built for shallow parts with small draw ratios they hold very close tolerances and can be mounted on temperature control bases and used with or without plug assist molds. b) Cast Aluminum Molds Cast aluminum molds are cast at a foundry from a pattern machi
