Detailed Product Inspections

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. However, product 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.

Product Quality Testing

MDI services include quality testing of your product. We can test the first products off the assembly line to ensure they are functioning as designed. Our testers can also evaluate products taken randomly from the assembly line. Testing the product’s functionality against a checklist while under production can highlight variations in product quality.When deciding on product quality testing, consider the following:

  • What is the product’s use? The higher the risk, the more important the testing. Food containers or packaging, along with children’s products are two markets with higher risk.
  • What marketing claims have been made? If your product is marketed as durable, then quality testing for durability becomes an essential component of your brand’s integrity.
  • What standards or regulations apply? Quality testing may be required depending on the industry.

You should also determine when to test. Testing at the start of production can identify problems that could impact the entire product line. Testing sample products during production using our rigorous testing standards can confirm that the last item off the line is the same quality as the first. The final quality assurance test before shipment can give you the peace of mind that your brand’s reputation for quality is intact.

Product Inspection for Quality Assurance

Quality assurance (QA) product inspections determine if products meet the required quality standards. QA inspections identify gaps and defects in products before, during, and after production. At MDI, we work with our clients to create a process of continuous improvement when it comes to the inspection and testing of products.

A QA inspection examines, measures, and tests the characteristics of a product. The results are then compared to the client’s specific requirements to see if the product met the stipulated standards. Using a pre-established checklist, our inspectors will evaluate products before, during, and after production.

QA inspections often occur in conjunction with detailed product inspections. We may conduct them before a product is placed in production. We can conduct random inspections throughout the production process to ensure that quality standards are being met. As with detailed product inspections, we can conduct a QA inspection prior to shipment. Our clients determine the frequency of the inspections.

Product Inspection and Testing

Inspections and testing are two parts of a quality control program. Product inspections look at the product for defects such as a scratch on a container or a misaligned edge. Product testing ensures that the product performs as intended. The evaluation checklists may include such things as “easy to open” to see if the product packaging frustrates the consumer. If the lid of a container should have an air-tight seal, then our inspectors will test the seal. The degree of testing or inspection depends on the client.

At MDI, we rely on our years of experience to deliver the quality inspection and testing services our clients have come to expect. Whether it is medical devices or manufactured goods, our skilled team is committed to delivering reliable testing and inspection services.
