NEW TEHNOLOGY IN COMPANY ROTO – 3D PRINTER

/in /von

Fast. Effective. Unique. All these are the most important qualities that characterize a 3D print of sand models and cores. 3D technology of the manufacturing process of foundry molds and cores, simplifies the creation of unique and low serial production.

3D printer technology was discovered and used first in the automotive industry as a top technology for the production of sand molds and cores for small batch products. Its discovery has significantly shorten the time of manufacture sand molds and cors and allow production of the most complex forms of prototypes.

In these times, when the time of delivery, price and fulfilling of customer requirements, extremely important is, is the use of 3D techmology for sand molds printing of great importance in a wide variety of technologies. Its advantages are fast and efficient production of sand molds and financial savings. Unlike other technologies, is with using of 3D prnters possible to manufacture geometrically complex shapes without limitation of negative angles. This technology is suited for manufacturing of prototyps, unique products, small batch production and aluminium casts.

BENEFITS OF 3D PRINTS:

–   fast and efficient production of sand molds,
–    only 5-7 working days from 3D CAD file till Finished model,
–    possibility of producing geometrically complex shapes,
–    there is no limit  with negative angles,
–    easier degassing of components,
–    low concentration of binder,
–    selection of different materials,
–    suitable for production of prototyps, unique products and for small batch production,
–    the possibility of a combination of 3D print mold with classic making sand molds.

Internal coating of aluminium tanks

/in /von

In the company ROTO, we put last year a lot of effort and knowledge in the conquest of the production process  according to rotomoulding, the so-called internally coating of aluminum tanks. The project itself was otherwisestarted four years ago with the introduction of our production program. Then we started serial production of the internal wall coating techniques and other fire extinguishers to dust. Last year, we have this process extended toother products, where for technical and technological requirements of the product such the coating required.

It is a special material (based on PE), which during the rotomoulding process, only be distributed throughout the interior walls of the aluminum tank, it adheres to the wall and also provides protection wall of aluminum tankagainst aggressive media (for example Ad Blue, powder fire extinguishers, …).
