For over 50 years we have been designing and injection molding plastic hardware used while manufacturing or repairing wood fixtures. We can take designs for new parts drawn on a napkin all the way to formal CAD designs. From drawings we can have rapid prototypes of parts created to verify form and fit prior to mold development.
