Moldmaking, machining, and mold repair

Injection molds built in Connecticut, and kept running.

We build prototype and production injection molds, repair and modify molds already in production, and machine the components that go into them.

Injection mold building

From a single-cavity prototype mold to multi-cavity production tooling, we build molds designed around your part, your resin, and your volume.

  • Prototype moldsFor design validation, testing, and short runs before you commit to production tooling.
  • Production moldsBuilt from hardened tool steels for long runs, with cooling, gating, and ejection designed for cycle time.
  • Mold sizeMolds up to [size and weight].

Mold repair for molders without a toolroom

If you run presses but don't keep toolmakers on staff, we can be your local tooling partner. Call us when a mold goes down, when a part needs an engineering change, or when tooling needs work you can't do in-house.

  • Emergency repairsBroken components, damaged shutoffs, and flash problems, turned around in [X days].
  • Engineering changesModifications when your part design changes after the mold is built.
  • Component replacementCore pins, inserts, ejector pins, and slides made to match.
  • Preventive maintenanceScheduled cleaning and refurbishment to keep molds running between jobs.

CNC machining and EDM

The same equipment we use to build molds is available for precision components, fixtures, and short-run machined parts.

CNC milling and turning

6-axis CNC machining of mold components, fixtures, and one-off parts, holding tolerances to ±0.001″.

Wire EDM

Complex profiles and precision cutouts in hardened steel, without the stress of conventional cutting.

Sinker EDM

Sharp internal corners, deep ribs, and blind features that a cutter can't reach.

Tool steels

A2, D2, S7, H13, and P20, plus the aluminum and stainless grades used in fixtures and components.

Machined steel pins, bushings, and spacers made by Empire Tool
