Product Inspection and Quality Control in Manufacturing Process

Product Inspection and Quality Control

When it comes to quality control and product quality inspection, a few industries take it as seriously. This is because defective products can cause problems, from disgruntled customers to serious safety concerns.

Manufacturers must have a robust quality control process to ensure that their products meet the required standards. However, quality control is not always straightforward, and manufacturers can take a few different approaches.

In this article, we will look at some of the methods of quality control and product inspection that are commonly used. So, let’s get started.

What is a Product Inspection?

The product inspection reviews the production process to detect defects and discover how they were introduced. It is a complex activity that relies on the whole manufacturing team’s visual inspection, document review, measurements, or performance evaluation.

QIMA inspectors inspect products, finished goods, raw materials, and containers. Inspections are held to check for defects and compliance with quality requirements. 

The most important steps of product inspection include:

  • Initial Production Check
  • During Production Inspection
  • Pre-Shipment Inspection
  • Production Monitoring
  • Pre-Customs Clearance Inspection

Product Inspection Expertise

As QIMA inspectors are trained to detect defects, you can rely on their expertise when designing the product inspection process. Inspectors are trained to understand the manufacturing process. Their goal is to ensure that all products meet quality requirements.

What is Quality Control?

Quality control is used in manufacturing to check if the product complies with specifications and requirements. You need a quality control team who has a set of standards for every product. It allows the company to ensure its goods are safe, on time, of the best quality, and affordable.

There are many ways to perform quality control: inspection, measuring equipment, data processing, and software analysis. With these methods, you can ensure that your products meet specifications and standards.

What is the Role of Quality Control?

The role of quality control is to ensure that all products meet required specifications and requirements. It means that there are certain standards to follow when producing a product. With these methods, you can ensure your products are safe, on time, of the best quality, and affordable.

Pre-Production Inspection

A pre-production inspection is when the manufacturer checks for product defects before proceeding with further production steps. This inspection aims to detect any defects before they reach the end customers. 

With this method, you can prevent any losses or extra work once your customers receive their goods.

Post-Production Inspection

A post-production inspection assesses the finished product after undergoing several production stages. This is done to check if the product meets quality requirements or specifications. After each stage in your manufacturing process, you will have to do this post-production inspection. For example, you could produce a car for roadworthiness.

Post-production inspection can be used for a variety of purposes:

  • Equipment testing 
  • Internal/external compliance testing (regulatory bodies) 
  • Packaging checking 
  • Finishing or coating checking 
  • Composition testing (chemicals, dyes, etc. in the products) 
  • Product certification (meeting legal and safety requirements in different industries) 
  • Material testing (scrutinizing packaging, pallets, or other goods) 

These methods can check if the product conforms to standards or specifications. It focuses on quality assurance to control quality and compliance with requirements. With these methods, you can prevent any losses or extra work once your customers receive their goods.

Container Loading Check

A container loading check is a process when you inspect the goods for quality before they leave the warehouse. This inspection aims to determine that all containers are in good condition. You can use this method to prevent losses or extra work once your customers receive their goods.

Product Monitoring

Product monitoring is a process in which you check the quality of your products and intervene to correct any issues. This is part of the product inspection and quality control. It is used for ongoing inspections of raw materials and semi-finished products during production.

This procedure aims to detect any defects that may occur during production. If a defect appears, you will have time to take action before it reaches customers or the end-user.

Why Get a Product Inspection?

You can improve your products’ performance and quality by using product inspection in your production process. This can prevent defects in the manufacturing process and ensure quality control. You can ensure that your products are safe, on time, and of the best quality.

If you want to improve results from your product inspection activities, It is important to select QIMA inspectors carefully. The QIMA inspectors should be trained for their specific roles in the manufacturing process.

They need to understand how the equipment works and what material they want to inspect for defects. In addition, they need to understand how each machine processes products as they move through a production line. 

Once you have selected a QIMA inspector, you must ensure they have the right qualifications and training to perform their activities. You can verify inspectors’ qualifications by checking the QIMA Certification Programme database. 

You should also confirm that they have a broad knowledge of different industries or expertise in specific manufacturing processes. These inspectors are trained for their specific roles in the manufacturing process.
