Process for making reusable tooling |
摘要 |
A reusable, low investment tool for making parts is made by a process in which a mixture of sand and an activator is applied as a layer onto which a printed resin is deposited to form a base and a pattern. A plurality of sidewalls may also be provided on the base using the same process. The tool is coated with a curable resin to form a protective shell. The reusable tool may be used as a dump box or as a vacuum forming tool for forming parts. A stamping die may be formed by drawing a vacuum through the sand layer as the resin coating is applied to more fully permeate the stamping die. |
