Market Segment:
Print & Paper Industry
Our partner is a manufacturer of professional printing equipment designed for long-term continuous operation. Addit executed a project involving the production of the structural frame for a large-format printer, serving as the primary load-bearing structure of the entire machine.
The key requirement of the project was to achieve exceptionally high manufacturing accuracy, including tight geometric tolerances, precise positioning of mounting holes, and long-term dimensional stability throughout the equipment’s service life. A particular challenge was minimizing welding-induced distortion while maintaining the required geometric accuracy of the frame.
Addit developed a dedicated manufacturing process incorporating specialized punching tools, advanced bending technologies, proprietary welding fixtures, and a multi-stage welding process. To further improve process repeatability, a robotic welding process was implemented, eliminating the need for post-weld straightening and significantly reducing finishing operations.
Scope of the Project:
- analysis of technical and quality requirements for the structural frame of a large-format printer
- development of manufacturing technologies for sheet metal components and precision machined parts
- implementation of punching, bending, and machining processes while maintaining tight geometric tolerances
- design and manufacture of dedicated inspection templates and welding fixtures
- development of a multi-stage welding process designed to minimize structural distortion
- implementation of a robotic welding process
- inspection of geometric parameters and manufacturing quality at every stage of production
- CNC machining and preparation of the structure for KTL (cathodic electrocoating) corrosion protection
- preparation of the manufacturing process for stable serial production with a high level of quality repeatability
