What it is

You design molds and tooling in CAD, check parts for manufacturability, then send the build to trusted machine shops and oversee quality and delivery. You work from a computer rather than running machines.

Your first three steps

  1. Set up CAD software and build two or three sample mold designs to show prospective clients
  2. Contact several machine shops and mold builders to learn their pricing, lead times and file requirements
  3. Reach out to product designers, makerspaces and startup groups to find your first small project
Who pays

Inventors, startups, product designers and small manufacturers who need a mold designed but have no in-house tooling engineer.

How it makes money

A design fee per project or hourly rate, plus a project management fee or markup on outsourced mold builds.

Skills that help
  • CAD design (such as SolidWorks)
  • Knowledge of mold design and plastics
  • Project management
  • Clear communication with clients and shops
Watch out for
  • Professional liability or errors and omissions insurance in case a design fault leads to a costly mold remake
  • Clear contracts on who owns designs, and NDAs for client IP
  • Payment terms with outside shops, so you are not out of pocket if a client pays late
  • Check your state and city for a business license and any home occupation rules if working from home
