If You Know Injection Molds, We Want to Talk.

We're looking for an experienced Tool & Die Maker / Mold Maker to join a growing precision manufacturing operation specializing in high-performance plastic injection molds.

This is an opportunity for a true craftsman who can build, repair, troubleshoot, fit, and finish complex molds — and who takes pride in getting the details right.

You'll work in a bright, clean, climate-controlled facility with sophisticated equipment, an experienced technical team, and the backing of an established international mold-manufacturing organization.

And it's a Monday–Friday day shift.

What You'll Be Doing

Build, assemble, repair, and maintain precision plastic injection molds

Perform mold fitting, spotting, assembly, and final finishing

Troubleshoot mold issues and determine appropriate repairs or modifications

Read and interpret complex mold drawings, blueprints, CAD models, and specifications

Machine and fit mold components to tight tolerances

Work with cores, cavities, inserts, slides, lifters, ejector systems, and other mold components

Perform precision grinding, milling, drilling, polishing, and bench work

Inspect components using micrometers, calipers, indicators, and other precision measuring equipment

Diagnose wear, damage, dimensional issues, and mold-performance problems

Perform preventative maintenance and mold refurbishment

Work closely with CNC programmers, machinists, engineering, and production

Support new mold builds as well as repair and modification of existing tooling

What We're Looking For

5+ years of Tool & Die, Mold Making, or precision tooling experience

Strong experience with plastic injection molds

Ability to independently assemble, fit, troubleshoot, repair, and modify molds

Strong blueprint and engineering drawing interpretation skills

Experience machining and fitting components to tight tolerances

Knowledge of mold construction, operation, and troubleshooting

Strong mechanical aptitude and problem-solving ability

Experience using precision measuring equipment

Ability to work independently while collaborating with engineering and manufacturing teams

Experience with
high-cavitation or thin-wall packaging molds is a major plus.

Why This Opportunity?

This isn't a massive production shop where you're just another number.

You'll join an expanding U.S. operation where experienced tooling professionals have an opportunity to make an impact and work directly with engineering, manufacturing, and leadership.

The company offers:

Extremely competitive compensation based on experience

Monday–Friday day shift

Overtime opportunities after 40 hours

Bright, clean, climate-controlled facility

Medical, dental, and life insurance

401(k) with company matching contributions

Company-provided work clothing

Overseas training opportunities in the Netherlands

Relocation assistance

Long-term advancement potential as the U.S. operation continues to grow
