We have been casting injection molding tools for over 3 years. A model
(SLA, and others) is used to cast the tool with the Albright process that
we developed.

Fastest we went from model to mold parts is two hours.

Tool life is over one thousand parts.

The mold is run in conventual molding machine at slightly lower injection

Run commercial and engineering resins

Surface finish is dependent on the master from highly textured to optical
