Frequently Asked Questions

What are the 4 types of quality inspection?

The four main types of quality inspection are: (1) Pre-production inspection, which checks materials and components before manufacturing begins; (2) In-process inspection, conducted during manufacturing to catch defects early; (3) Pre-shipment (final) inspection, performed on finished goods before delivery; and (4) Container loading inspection, which verifies correct packing and loading. DM&E performs in-process and final inspections as standard within every project workflow.
