production processes & machinery
At ProTec Metalltechnik we rely on the most modern production processes to ensure the highest precision and efficiency in metal processing. Our production includes innovative techniques such as punching, bending, forming processes and joining techniques, which we implement with our modern machinery.
Our welding cell is equipped with a fully equipped welding robot. Depending on the component size and batch size, we use the cell in one or two shifts. This means we can efficiently process either larger components or smaller series. For arc welding, we use a special Fronius power source that supports the innovative PMC (Pulse Multi Control) pulsed arc process. This combination guarantees first-class results and the highest quality in our welding processes.
2D and 3D laser cutting
Laser applications, especially laser cutting, are becoming increasingly important in component production.
The technology enables precise cuts at high speeds and is suitable for various materials such as metals, plastics and ceramics.
Advantages of laser cutting are high precision, speed, versatility and the possibility of automation.
Overall, laser cutting remains an effective method for efficiently producing high-quality components.
Punch-laser combination
The combination of punching and laser processes in our production offers numerous advantages.
It enables precise cuts, even with complex geometries, which leads to a high level of accuracy.
In addition, integration into a single system increases efficiency as several processing steps are carried out in one pass.
This technology is flexible and can process different materials and thicknesses.
Deep drawing
Deep drawing is a key technique in automotive production that involves forming flat sheet metal into complex 3D shapes.
Advantages include weight reduction, cost efficiency through mass production, high precision and optimal material utilization, which minimizes the amount of waste.
In addition, the materials used are easily recyclable, which promotes sustainability.
The process is used for various components, from body panels to doors and hoods, often combined with techniques such as laser cutting to ensure high standards of safety and design.
Robot bending | edge
Robot bending is a modern manufacturing technology that enables precise and efficient component production.
Robots offer high accuracy and repeatability, creating precisely fitting parts.
They can be used flexibly for various bending operations and increase efficiency and reduce costs through automation.
Robots also increase safety by taking on dangerous tasks and can be equipped with sensor systems for quality assurance.
Robot welding
Robotic welding plays a crucial role in our production as it enables precise, efficient and high-quality welded connections.
Robots are used for various processes such as MIG/MAG, TIG and spot welding, ensuring flexibility and versatility in manufacturing.
The use of robots also increases productivity, reduces manufacturing costs and reduces the risk of injury to employees.
With integrated sensor systems, the weld seam quality is monitored in real time, which improves quality assurance.
manual welding
Manual welding remains essential, especially for complex and individual welding work.
It offers adaptability to different materials and geometries, which is important for prototypes and custom-made products.
Manual welders have high technical skills that lead to robust welded connections.
It can also be used flexibly for repairs and adjustments to existing components.
Strict quality control ensures compliance with standards.
In this way, manual welding optimally complements automated production for high-quality components.
Spot welding
Spot welding is an efficient welding technique that joins two or more metal parts using a burst of electrical current.
It increases productivity through automated equipment and provides strong, reliable connections, ideal for body panels and frames.
It guarantees consistent quality and can process various materials such as steel and aluminum.
It is also more environmentally friendly than other processes.
Spot welding is widely used for auto body parts and continues to improve manufacturing processes and quality standards in the industry.
Press in
Press-fitting is a significant joining technique that enables precise and repeatable connections between components.
It is carried out using special stamps or presses and offers high efficiency and the possibility of automated production.
The compounds created are strong and durable and can be used for various materials.
Quality assurance is facilitated by visual controls and measuring devices.
Applications include pressing bearings, bushings and bolts into body panels and other assemblies.
Spot welding is widely used for auto body parts and continues to improve manufacturing processes and quality standards in the industry.
Clinching
Clinching is a widely used joining technique in which two sheets of metal are joined through plastic deformation, without additional materials such as adhesives or welding consumables.
This method provides precise, repeatable connections with tight tolerances and is efficient in automated production lines.
Clinching can be used on various materials such as steel and aluminum and helps reduce waste and environmental impact.
The connections created are stable and offer high strength, making them ideal for various components.
Trowalize
Trowelizing is a chemical process that is typically used in the production of components and workpieces for surface processing and finishing.
In this process, the workpieces are placed in a container filled with abrasive material (troweling agent).
The workpieces are processed through mechanical movement or vibration, resulting in smoothing of the surfaces, reduction of vibration noise and improved aesthetics.
At the same time, burrs can be removed and minor irregularities can be leveled out.
Wash components
Component washing is crucial for the quality and functionality of components.
It removes contaminants such as dust, oil and chips, which improves surface quality and increases process reliability.
Cleaning detects possible defects, which contributes to quality assurance and minimizes waste.
Component washing takes place in various phases of production, such as before processing, assembly or painting.
Different processes such as ultrasound, spray, immersion or compressed air cleaning are used to achieve optimal results.
