Why This Resume Works

1
Mold types and materials are specific

Multi-cavity, hot runner, and named steel grades show depth beyond generic mold making claims.

2
Surface finish standards are named

SPI A-2 is an industry-recognized standard that tells employers exactly what quality level you deliver.

3
Production impact is quantified

1M+ parts per mold lifetime and lead time reductions connect shop floor work to business outcomes.

Section-by-Section Breakdown

Common Mistakes on Mold Maker Resumes

  • Not specifying mold types - Multi-cavity and two-shot molds require different skills than single-cavity. Be specific.
  • Omitting surface finish standards - SPI grades are the language of the industry. Include them to show your quality capabilities.
  • Missing mold flow software - Moldflow and similar tools are increasingly expected. List them if you have the experience.
  • No mention of mold repair work - Repair and refurbishment skills are valuable and extend mold life. Include this experience.
  • Vague material references - Saying steel is too generic. P20, H13, and S136 tell employers what you can work with.
