An injection molded part specification tells your molder exactly what the final product requirements are. Specifications are intended to inform engineers and satisfy the end-use requirements for the application. These requirements should include aesthetic, functional, environmental, and economic requirements. Therefore, the final part should match the complete set of molded part specifications.

These specifications should include:

1. Material (brand name, grade, generic)
2. Surface finish
3. Parting line location
4. Flash limitations
5. Gate location and weld lines (away from critical stress points)
6. Locations where voids are not allowed
7. Allowable warpage
8. Color (Pantone PMS)
9. Decorating requirements and artwork
10. Performance requirements and testing methods (if applicable)
