In any industry, you need to have a series of controls to guarantee that each one of the products that leaves the plant has the correct specifications. At E2M COUTH, we are specialists in inspection systems for quality control. For this reason, in this post, we will tell you about the different systems that exist, as well as the benefits they can provide to any kind of industry.

What is an inspection system for quality control?

Inspection systems for quality control can be defined as a series of tools that are used to examine and assess products and manufacturing processes within an industry. The main objective of this kind of system is for all products to meet established quality and safety requirements at all times. They also seek to make production processes efficient and effective.

As we will see later on, inspection systems for quality control may use different methods to reach their objective, such as visual inspection, dimensional measurement, etc. Additionally, this kind of system may be manually controlled or in automated fashion and can be used at different stages in the production process.

In using these systems, what we seek and achieve is a quality guarantee for each one of the products and processes within an industry, as well as compliance with applicable standards and regulations.

Discover the different kinds of inspection systems for quality control

Within inspection systems for quality control, we can find different kinds of tools that can measure and assess different aspects of products that may come out of an industry. Next, we are going to talk about some of each one of their most noteworthy aspects.

Vision inspection

We will begin with inspection systems for quality control that use vision inspection. By means of observation, this kind of system can detect any defect or anomaly. A worker could conduct this mission, so it is best to choose an automated system which, by using cameras, sensors, and specialised software, can detect any type of anomaly or problem in the product.

Dimensional inspection

We are now moving on to another inspection system for quality control that is one of the most important in existence: it conducts a dimensional inspection on the products that leave your production plant. They are in charge of assessing the dimensional precision of products, guaranteeing that they meet with required specifications. To achieve this proper inspection, measurement devices are used, which may be calibres, micrometres, coordinate measurement sensors, and more.

Radio frequency inspection

We know that industries that work on making products can be very different from one another. In other words, there is a wide variety of products that must be inspected. For this reason, there are also inspection systems to control quality that use radio frequency.

These are perfect for assessing the integrity of opaque items, like plastic or metal, by detecting internal or structural defects through the use of radio frequency. This kind of system is often used to inspect welding, machine parts, electronic components, and other kinds of products.


Ultrasound inspection

Inspection systems for quality control also include systems that use ultrasounds to detect all kinds of errors. This kind of system emits a series of sound waves that reflect on the object and are recorded by the system thus finding any kind of issue the product may have.

Tomography inspection

Continuing on with another inspection system for quality control, we have tomography. This kind of system generates a series of three-dimensional images of products to detect all kinds of defects or anomalies. They are normally used to inspect complex products, such as machine parts, electronic components, and more.

Sampling inspection

Within an industry, different kinds of inspection systems can be used for quality control. One of these is a system that works with sampling. This process is fairly simple, since it consists of inspecting a randomly selected sample from a production batch. This way, you can determine whether it meets the established quality requirements. When the sample passes the quality test, it is considered that the entire batch meets requirements.

Variable inspection

These inspection systems for quality control are set up to measure a specific characteristic, such as the height or diameter of an object. Instead of assessing whether a product complies with a set of specific criteria, it measures the amount of variation in a particular characteristic.

Thermal chamber inspection

This other quality inspection system is recommended for products that must meet a series of requirements related to their temperature. With these systems, you can detect the presence of heat leaks, which could mean that there are different insulation issues with electrical connections. This thermal chamber measures the temperature of an object’s surface, showing differences in temperature as colours in an image.

Laser inspection

Continuing with another inspection system for quality control, in this case, we have a system used for products where precision is important. Laser systems measure the dimensions of an object with high precision and are used in industries that manufacture electronic or mechanical components. This technique bases its operation on laser reflection to measure the distance between the object and the measurement sensor.

Destructive test inspection

In the industrial sector, there are different methods to check product quality. In this regard, we have inspection systems for quality control that work by means of a destructive test. They are used to assess a product’s resistance or durability by subjecting it to extreme or laden conditions to see when it fails.

This is a costly technique that requires time, so it is normally used in specific cases or when quality standards are very demanding.

Fluorescent inspection

Lastly, out of the quality control systems in existence, we can find ones that work with fluorescence. They are used to detect the presence of certain chemical elements in a product. They operate by applying a fluorescence agent to an object and then using an ultraviolet light to see if there is fluorescence in specific areas. This would indicate the presence of harmful elements for the product.


Learn the benefits of having an inspection system for quality control.

In any kind of industry, using inspection systems for quality control can provide a wide variety of benefits. These benefits are:

Improved product quality

With inspection systems for quality control, you can identify different defects or flaws in the product during the production process. With this, you can quickly correct and guarantee that the end product meets all quality requirements.

Reduced costs

With inspection systems for quality control, what we are looking for is early identification of any problem that may occur during the production process. This makes it possible to reduce costs related to repairs or remaking products with flaws.

Moreover, these inspection systems also help to identify the source of the problem and therefore prevent future errors, thereby reducing expenses associated with this problem.

Increased efficiency

With inspection systems for quality control that operate in automated fashion, you achieve a higher level of speed than with a manual inspection. This makes it possible to increase efficiency for the entire production process. Moreover, using automated inspection systems also reduces the need for manpower, which can also help to improve productivity.

Quality standard compliance

Certainly, one of the greatest benefits of quality inspection systems is that, as a company, you can comply with quality standards. This means that, when you apply these systems, you can guarantee that all your production complies with the standards required within your industry. This helps to improve the company’s reputation, as well as customer satisfaction.

Improved security

As we have already seen throughout this text, inspection systems for quality control can identify different security issues in products before they are distributed. This can reduce the risk of injury or harm to the product’s end users.

Get statistics

Another great benefit that using inspection systems for quality control has, is that they can offer statistics on the entire process. At E2M COUTH, we know that not all factories work the same way, and that not all products have the same variables. With these systems, you can obtain statistical data to draw conclusions regarding the operation or quality of different products from your plant.

Why use inspection systems for quality control at an industrial level?

Using inspection systems for quality control is practically mandatory for any kind of industry, because it means companies can guarantee consistency, efficiency, and reliability for the products or services they offer. By using these systems, it will be easier to detect all kinds of problems and correct them before they reach the customer’s hands. This reduces the likelihood of complaints, returns, and costs associated with these issues.

These systems will also help you as a company to comply with the different quality, security, and environmental standards and regulations applicable within your company’s sector. This may include industry-specific standards, as well as governmental regulations that must be complied with to guarantee customer safety and satisfaction.

They are also essential to improving the efficiency and productivity of a company, reducing the time and resources necessary to identify and correct all kinds of issues in production. This translates to greater profitability and competitiveness for the company.
