Detailed Product Inspection Services
Product inspections ensure product integrity. Inspections can occur at any point in the production process. Many manufacturers have their products inspected as production is finishing. These inspections are usually divided into three categories.
- Pre-Production: These inspections are performed before production starts. If some materials have high-quality standards or detailed specifications, the raw materials may be inspected to ensure they meet the necessary standards.
- Production: Inspections performed during production may be random. Individual products are pulled from production for inspection. The random products are evaluated against a checklist to ensure that quality standards are being met.
- Pre-Shipment: Inspections conducted prior to goods being shipped are the last check to ensure products are ready for delivery.
In addition to the product, our team will inspect packaging and labeling. They will even confirm that instructions are present if that is part of the final deliverable. By using MDI’s product inspection services, our clients can:
- Ensure product quality
- Protect their reputation
- Optimize their quality control budget
With MDI’s years of experience, you can rely on our inspections for product integrity.
