Quality Control in the Automotive Industry. 7 things you should know about ISO 16949

Essential quality control in the automotive industry is the basis of a management system. In addition, they offer perfection and optimization in production processes to guarantee compliance with regulations.

That is why we want to introduce you to the different inspection systems in the automotive sector.

Quality control in the automotive industry

The quality, safety, and performance of a car and its parts are directly proportional. There must be dedication and a lot of attention to the pieces’ effectiveness to ensure usability. Thanks to this, the value of the product will increase.

For this reason, inspection systems must be made to improve manufacturing productivity.

Inspection system

It is responsible for examining and measuring the characteristics of a product, including its materials and elaborated components. They use measuring instruments, test equipment, or comparison standards that verify if it meets the requirements, and which means that it confirms if the system works properly.

They are usually done by sampling, and 100% control is only used when they are safety features or essential standards.

In the case of inspection in the automotive sector, they are dedicated to directing the guidance of machines. They also perform a visual inspection of parts to improve the quality of the product and thus determine if they are acceptable or defective.


Five inspection techniques in the automotive sector will guarantee your success. Let’s see.

1. The robotic

It is one of the industry’s most advanced and widely used automation technologies. Applied robotics allows a robot to locate the part regardless of rotation or scale.

Machine vision systems mainly provide data in real time. Capable of guiding robots through programmed sequences of operations. The robot picks up the part and then verifies its correct location. Next, proceed with the assembly.

2. X-Ray Inspection

This kind of non-destructive inspection becomes vital within the industries for its sound development. With this technique, it is unnecessary to make alterations or cause damage to the assembled equipment. This way, you can have an excellent vision to detect flaws if they do not meet quality standards.

3. Gauging dimensional

It can recognize accurately and with easy programming. It is a new generation of inspection systems that guarantee success. Likewise, it involves a variety of odd lines, arcs, diameters, and angles. It has few exceptions and can measure faster and more reliably.

4. Visual inspection or PPAP

Through this process, we seek to establish bonds of trust between the components and the production processes. A manual way of approving the different parts used within the production. This will demonstrate that the final result will meet the demands and needs of the client.

5. Mounting verification

Look for patterns and detailed shapes capable of matching the templates for the sub-assemblies that have been created. Perform inspections better than any other process.

6. Print verification

Vision systems inspect components and parts when various optical character verification methods are applied. This ensures that they are marked correctly.

However, it is not an easy task. Vision systems must learn to deal with characters, shapes, and ink variations. In the same way as engraving and stamping.

7. 2D code reading

It has enormous potential for the automotive sector. Systems vision is used to read them and then use the information for monitoring, verification, and quality control. It has low contrast and can be degraded or worn during production.

PPAP Process

This Production Part Approval Process (PPAP) is the industry standard. Ensures engineering design requirements and product specifications are met. The principles in this guide reduce delays and nonconforming products in part approval.

The PPAP determines if the company correctly understands the requirements found in the design specifications. It also specifies that the manufacturing process has what it takes to make the products.

It is essential to achieve effective management in automotive industry components. And it is a factor that involves all supply chains, especially in areas like the lowlands of Mexico, Querétaro, where it has distinguished itself as having the most important manufacturing companies in the automotive sector.

At AMN Quality Solutions, we understand what that means. That is why we offer quality inspections with the highest technology in our processes. What will keep you in the highest standards of the market?
