What EFI is

A molder that owns the whole part, not one operation.

EFI has been a custom injection molder since 1976, and has expanded steadily across tooling, molding, over-molding, laser marking and assembly — through in-house operations, strategic partnerships and joint ventures.

The customer base today is globally diversified and balanced between automotive and non-automotive work, run out of Troy, Michigan.

Capabilities

Everything a molded part needs, under one roof.

Injection molding is the core of the business. Tooling, over-molding, marking and assembly are built around it — and molded, over-molded and assembled components all sit inside EFI’s registered IATF 16949 scope.

Injection molding: inside the press

Cutaway of a two-platen injection molding press: molten polymer entering the mold cavity between the platens, with the screw and barrel to the right.

Injection molding

  1. 01

    Hopper

    Plastic pellets are fed into the molding machine.

  2. 02

    Barrel & screw

    Material is heated and conveyed forward by a rotating screw.

  3. 03

    Injection

    Molten polymer is injected into the mold under pressure.

  4. 04

    Mold

    The material fills the cavity and takes the required shape.

  5. 05

    Cooling

    The part cools and solidifies against the mold surfaces.

  6. 06

    Ejection

    The finished part is released from the mold.

How a program runs

From a print to a packed skid.

Every stage below is something EFI does. Nothing here is outsourced language for “we will find someone.”

01

Concept & Review

We start from your print or model and talk through what the part has to do, the volume it has to hit, and the timing you are working to.

3D Printing
02

Prototype & Validate

3D printed sample parts prove geometry, fit and material direction before anyone commits a tool.

3D Printing
03

Tooling

We build the mold - prototype tools through large-scale production molds - specified for the program it has to run.

Tooling
04

Sampling

First parts off the tool, reviewed against the print and the process before production is released.

Injection Molding
05

Production Molding

Molding and over-molding under an IATF 16949:2016 registered quality management system.

Injection Molding
06

Marking

Precision laser engraving for part identification, branding and labeling, applied in-house.

Laser Engraving
07

Assembly

Components built up into finished assemblies - inside the same certified scope as the molding.

Assembly
08

Delivery

A quality product, delivered on time, at value-added pricing. That is the standard the company has run on.

Quality

We don’t just make parts. We run a process customers can audit.

EFI’s IATF 16949 registration is not a badge on a website — it is an audited scope, and this is exactly what it says:
