Franzen Manufacturing in detail
Sheet metal selection and sheet metal cutting
Production begins with sheet metal selection: in our modern high-bay warehouse, the sheets are stocked in the required grades and thicknesses. They are selected according to demand and fed directly into production. This is followed by sheet metal cutting – a core area of our manufacturing expertise. It is carried out on modern, computer-controlled sheet metal processing machines that produce the required sheets exactly to your individual specifications.
Machinery that impresses
For sheet metal cutting, our production facility has two TRUMPF punch-nibbling machines available. Operating both machines in parallel provides high capacity and additional redundancy – so your orders remain in production even during maintenance intervals. The machinery is complemented by a TRUMPF laser cutting system with 4 kW power. It delivers clean, precise cut edges, even for complex contours and delicate details.
CNC-controlled: from the design data straight onto the sheet
The entire cutting process is CNC-controlled. The design data flows directly from the engineering department into the machine control – without any manual intermediate steps. What has been designed on the computer is produced with the same precision on the sheet. This reduces potential sources of error in data transfer and speeds up the production process.
Individually to customer specifications
Whether special dimensions, individual cut-outs for locking cylinders, spy holes or ventilation grilles, or custom hole patterns – we manufacture all of this for you without extra effort. Every door is produced dimensionally accurate to your specifications and fits perfectly into your structural conditions and design wishes.
Punching, nibbling and laser cutting from a single source
For each component, we choose the technically appropriate and most economical process. This flexibility allows us to manufacture simple standard sheets just as efficiently as highly complex components. Through optimized sheet utilization with intelligent nesting of the cut parts on the sheet panel, waste remains low – which has a positive effect on cost efficiency.
Bending and hemming: components shaped with precision
After cutting, the sheet metal parts are given their shape through bending and hemming. On our press brakes, door leaves, frames and reinforcements are formed – dimensional accuracy is maintained even with multiply bent profiles. During hemming, the sheet edges are securely closed, creating stable edges and smooth transitions where neither moisture can penetrate nor sharp edges are exposed later on. This gives every door a precise framework for the subsequent production process.
Consistent quality
Our automated production processes deliver reproducible results – from one-off items to series production. Every sheet metal part meets the same strict accuracy requirements.
In-house paint shop
Finally, the door leaves and frames pass through our in-house paint shop. Here they receive a uniform, permanently high-quality surface – in a wide range of colours to match your individual design. From pretreatment to the final coat, every production step stays under one roof, which ensures consistent surface quality from sheet metal processing to the finished door.
Short distances, short delivery times
The entire production process, from cutting through bending to priming and painting, takes place in our own factory. This keeps distances short and communication direct, allowing us to respond flexibly to your wishes.
