Consistently controlled quality

We ensure continuous defect detection and process stability, reducing the risk of non-compliance, customer complaints, and production losses through inspection systems integrated directly into existing processes.

What is industrial quality control?

Industrial quality control involves identifying defects before products reach the customer or move on to the next stages of production.

Inspection systems are integrated directly into the production line and check every product or batch consistently and reliably.

Industrial inspection technologies

There are several technologies used, depending on the type of product and the associated risks:

  • Metal detection systems are used to identify metal contaminants in products, particularly in the food and pharmaceutical industries.
  • X-ray systems enable the detection of foreign objects as well as the analysis of a product’s internal structure, including density variations or missing components.
  • Industrial vision systemscheck for visual aspects such as the presence of components, positioning, labels, codes, or surface defects.
  • Checkweighers monitor the weight of products on the production line, identifying deviations from set values or incomplete products.
  • Dimensional inspection systems measure the dimensions, positions, or tolerances of parts, ensuring that they comply with technical specifications.
  • Statistical Process Control (SPC) systems collect and analyze data from the production process, helping to identify deviations and prevent defects before they occur.

The type of defects that need to be identified, along with the actual production conditions, determine the choice of inspection system and how it must be configured to function properly.

Quality control applications

Testing for contaminants in packaged products

Detection of foreign objects in food products.

Checking product presence and integrity

Check that the package is sealed and that all components are present.

Checking labels and codes

Verifying the accuracy of the label and the readability of the barcodes.

Detection of visual or structural defects

Identifying scratches, dents, and discoloration.

Product weight control
Verifying the correct weight and detecting incomplete products.
Verification of dimensions and tolerances
Measuring dimensions and verifying compliance with specifications.

Manual verification vs. automated inspection

Manual verification depends on the operator and varies depending on attention, fatigue, and work pace. In high-volume processes, variability becomes a real risk, and many aspects cannot be verified manually.

Automated inspection ensures consistency and repeatability. The systems inspect each product under the same conditions, without variation, and can operate continuously across multiple shifts.

Traceability and defect prevention

Modern systems do more than just reject non-conforming products. They record data on each inspection, including the type of defects and their frequency.

This information enables the rapid identification of process issues and the prevention of recurring defects. In many industries, traceability is a mandatory requirement, not just an option.Quality control thus becomes a tool for continuous improvement, not just a final filter.

Integration into existing workflows

Inspection systems are designed to be integrated directly into existing production lines without major modifications. In most cases, they are positioned on conveyors or at key points in the production flow.

Proper integration depends on positioning, synchronization with the line, and how rejected products are handled. A well-integrated system operates without disrupting the production pace.

The cost of inspection systems

The cost is not determined solely by the equipment, but by the impact on the process. The investment must be evaluated in relation to the risks it helps avoid: non-conforming products, complaints, recalls, or production losses.

In many cases, cost savings result from mitigating these risks and stabilizing the process. Inspection systems are particularly essential in applications where a defect can lead to significant costs.

FAQ

What types of defects can be detected automatically?
It depends on the technology used. Metal detectors identify metallic contaminants, X-ray systems can detect foreign objects and density variations, and vision systems check for the presence, positioning, labels, or visual defects. In practice, the solution is chosen based on the specific risks of the application.
The material, shape, and composition of the product directly affect its performance. Wet or conductive products can interfere with metal detectors, and metallized packaging may require the use of X-rays. Therefore, the solution must be validated on the actual product, not just based on specifications.
Systems can handle variations, but only within certain limits. If the product varies significantly in shape or composition, it is necessary to adjust the parameters, define multiple recipes, or use different inspection technologies.
The rate depends on the application, product, and configuration. Under the right conditions, the systems offer a high level of detection, but actual performance is always validated in a production environment. Initial tests are for reference only and are not definitive.
By setting the sensitivity correctly and adapting the system to the product. A system configured to be too aggressive will generate unnecessary rejections, while one that is too lenient may miss defects.
Not on a constant basis, but periodic checks are necessary to confirm proper operation. These are usually performed using test products and are part of standard quality control procedures.
The systems record detection events, rejections, and operating parameters. This data can be used for traceability, auditing, and optimizing the production process.
These issues usually arise from overly sensitive settings or product variations. Adjusting the parameters and validating them under real-world conditions significantly reduces the frequency of these issues.
The cost savings come mainly from avoiding complaints, product recalls, and losses caused by undetected defects. In critical applications, the impact is immediate.
Choosing the right technology and configuring it correctly makes the difference between a stable system and one that causes problems. In Multitech implementations, applications are tested under real-world conditions, systems are configured correctly, and performance remains stable and predictable in production.
