Molding Tolerances Chart

Access Molding Tolerances for Your Material


Molding tolerances vary depending on the material you’re using for your application.


Since tolerances ultimately impact your mold’s capabilities and production cost, K&B has developed a Molding Tolerances Chart that breaks down tolerances by six commonly used molding materials:

  • ABS
  • Polyamide (Nylon)
  • Polyoxymethylene (Acetal)
  • Polycarbonate
  • Polypropylene
  • Thermoplastic Polyester


Each of the injection molding materials includes tolerances for both Fine and Commercial classes, depending on your specific project. This will give you a sense of the narrowest tolerances available vs. the most economic tolerance choice.
