At Perfect Patterns, we are capable of building your most complicated
low-pressure permanent and semi-permanent molds from hardened materials such as
4140, H-13 or gray iron. Our EDM capabilities allow us to ensure dimensional and visual
perfection of your most intricate features while keeping to the
ever-shortening production schedules. All molds are draw polished by
hand with stones to create a surface finish any foundry would envy. We
can fully engineer and rig your mold with gating, ejection, and
hydraulic slide pieces to fit your custom mold machine.
