In the metalworking industry, the quality of a component does not depend solely on how it is produced. It also depends on how it is checked, controlled, and validated before it reaches the client.
In sectors where precision, repeatability, and reliability are critical factors, small dimensional variations, surface defects, or functional deviations may compromise the performance of the final product. For this reason, Inspection / Sorting plays an important role in the production of metal components, by adding an additional layer of control to the production process.
At ETMA, this capability is part of the company’s system of 10 Integrated Production Processes and is supported by a dedicated department, equipped with universal automatic inspection solutions and custom-made equipment. The aim is to respond to the technical requirements of each project by performing 100% control, in accordance with the control and inspection plan defined by the client.
More than a final operation, Inspection / Sorting represents an important technical advantage: it helps reinforce part conformity, reduce risks before dispatch, and increase confidence in supply.
- 100% CONTROL: A RESPONSE FOR MORE DEMANDING PROJECTS
In many industrial processes, sampling control is sufficient to monitor production stability. However, there are projects in which the technical demands, the critical nature of the application, or the client’s requirements make a more comprehensive level of control necessary.
This is where 100% control becomes particularly relevant.
By enabling all produced parts to be checked, this approach helps reduce the risk of non-conforming components being dispatched. This capability is especially important for parts intended for sectors such as automotive, moped, electrical, home appliances, fastening, and technical components, where every detail can influence the assembly, operation, or reliability of the final product.
In practice, Inspection / Sorting does not replace production rigour. It complements it through a validation stage focused on the criteria defined by the client, helping to ensure that the supply complies with the established requirements, part by part.
- GREATER SAFETY BEFORE DISPATCH
A non-conformity identified too late may lead to complaints, rework, delays, additional costs, or disruptions to the client’s assembly line.
Inspection / Sorting makes it possible to act before that stage, identifying deviations before the parts are dispatched. This is one of its main contributions: reducing risk at a critical stage of the process, before the product reaches the client.
This control may focus on different criteria, according to the plan defined for each project. In some cases, the focus is on dimensions. In others, it may be on visual appearance, shape, the presence of surface defects, or specific functional parameters.
In this way, inspection is directed towards what truly matters in the final application of the part. It is not just about checking. It is about controlling the aspects that may influence component performance and supply reliability.
In series production, this capability becomes even more relevant, as consistency between parts and between batches is essential to ensuring stability and predictability over time.
- TECHNOLOGY ADAPTED TO THE REQUIREMENTS OF EACH COMPONENT
Not all metal components require the same type of inspection. The geometry of the part, the material, the function, the production volume, and the client’s level of requirement directly influence the most suitable control method.
At ETMA, Inspection / Sorting may include different methods, ranging from visual control of appearance and shape to dimensional systems with artificial vision cameras, latest-generation lasers, Eddy current testing for the detection of hardness-related and surface defects, as well as torque control.
This technological diversity makes it possible to adapt the response to different industrial needs. Artificial vision and laser systems contribute to greater speed, repeatability, and accuracy in dimensional control. Eddy current testing helps strengthen the detection of certain defects in metal components. Torque control, in turn, is applied when the functionality of the part or assembly requires validation of that specific parameter.
The advantage lies precisely in the ability to select the most appropriate inspection method for the technical requirement in question.
Because, in an industrial environment, quality does not depend only on having technology available. It depends on knowing how to apply it correctly, to the right criteria, and according to the demands of each project.
- EQUIPMENT, TECHNICAL TEAM, AND TAILOR-MADE SOLUTIONS
ETMA’s Inspection / Sorting capability is supported by equipment such as Mectron LT350, General Inspection 300, Omron Vision, Vimetrica, as well as solutions developed according to the client’s specific needs.
This combination of standard equipment and customised solutions makes it possible to respond to very different challenges. Some parts can be inspected using universal automatic systems. Others require specific adaptations, whether due to their geometry, the type of defect to be identified, the production volume, or the criteria defined by the client.
But technology alone is not enough.
This process also requires a technical team prepared to interpret requirements, apply the appropriate measuring instruments, and perform dimensional and visual sorting with rigour. This human component remains essential, especially when the process involves technical analysis, decision-making ability, and knowledge of parts, materials, and applications.
It is the combination of equipment, experience, and adaptability that results in a more robust response. In practice, ETMA is able to transform a control requirement into an industrial service tailored to the project.
- AN INTEGRATED ADVANTAGE IN THE PRODUCTION OF METAL COMPONENTS
Inspection / Sorting is a cross-cutting capability, applicable to different materials, parts, and sectors of activity.
ETMA works with materials such as steel, stainless steel, brass, aluminium, and copper, used in technical components for different industries. This process can be applied to a wide variety of parts, including nuts, springs, hinges, clips, terminals, washers, electrical connectors, tubes, protective housings, axles, shafts, screws, circuits, injector parts, bushings, compression limiters, knurled parts, rivets, and assembled units.
This scope demonstrates the versatility of the process and its value as a validation stage for components with different functions, dimensions, and levels of complexity.
Within ETMA’s context, this capability becomes even more relevant because it is integrated into a broader production structure. Inspection / Sorting does not appear as an isolated operation, but as part of an industrial system that brings together different production processes, technical teams, and control solutions.
For the client, this integration means less complexity in project management, greater technical proximity, and increased confidence in the conformity of the parts supplied.
CONCLUSION
Inspection / Sorting adds value to the production of metal components because it makes it possible to validate parts according to the technical, dimensional, visual, and functional requirements defined for each project.
At ETMA, this capability is supported by specialised equipment, tailor-made solutions, a skilled technical team, and 100% control, always in accordance with the client’s control and inspection plan.
In practice, Inspection / Sorting makes it possible to:
- reduce the risk of complaints by identifying deviations before dispatch;
- increase client confidence through control aligned with their own requirements;
- enhance the value of the final product by ensuring visual, dimensional, and functional conformity;
- support demanding sectors where precision and repeatability are essential;
- create tailor-made solutions through the adaptation of inspection equipment and methods.
Integrated into the system of 10 Integrated Production Processes, this capability reinforces ETMA’s ability to supply metal components with greater rigour, consistency, and reliability.
Because, in industry, producing well is essential. But ensuring that each part corresponds to what has been defined is what transforms that rigour into confidence for the client.
