Contract manufacturingIndividual components, assemblies, series production

Scale your business thanks to our contract manufacturing in mechanical engineering: Benefit from high-quality individual components to pre-assembly or fully assembled machines from a single source.

With our large capacities and high standard of digitization, we only need your construcion data – our robot lines, automated measurements and 5-axis milling do the rest for you.

Allowing you to concentrate on your core business.

The secret heros: Our robotic lines

Ideal for your single parts and series production, our fully automatic robot lines measure components, select the right milling tool from up to 1,000 stored milling tools, mill your component and then clean it to achieve the most accurate results during the subsequent measurement test. If something doesn’t fit, the component is sent straight back to automatic machining.

For perfect dimensional accuracy in record time in our contract manufacturing.

Making sure it fits: Measuring room and measurement technology

For best precision and highest accuracy: Our automatically supported measuring processes ensure that you receive your components exactly as designed.

While our measuring room inspects smaller components, we can check larger components for accuracy directly in the producing machine. Optimization potential is thus quickly identified and immediately perfected thanks to our automatic robot lines.

Assembly options in contract manufacturing

Even though a lot happens fully automatically in our mechanical engineering – some processes are still best handled manually. Therefore, if necessary, our experts process, wire and pre-assemble by hand or install complete machines, such as those from our customer Concept Laser.

As always at Hofmann, we focus on your requirements when it comes to contract manufacturing.
