Mold and die inspectors are responsible for ensuring that molds and dies meet the required specifications. They inspect the molds and dies for defects, and they also measure and test the molds and dies to ensure that they are within tolerance.

1. Inspect molds and dies for defects

Mold and die inspectors use a variety of tools and techniques to inspect molds and dies for defects. They may use visual inspection, dimensional measurement, or non-destructive testing to identify defects.

• Visual inspection involves looking for defects on the surface of the mold or die.
• Dimensional measurement involves measuring the mold or die to ensure that it meets the required specifications.
• Non-destructive testing involves using special equipment to test the mold or die without damaging it.

2. Measure and test molds and dies

Mold and die inspectors also measure and test molds and dies to ensure that they are within tolerance. They may use calipers, micrometers, or other measuring tools to measure the mold or die.
