Premiapri Nova by MERONI SERRATURE was born in 1973 from an idea by Giulio Andrea Meroni, which soon became an unmistakable product, a timeless classic among the icons of Italian design. The object, which opens every door in a single functional and immediate gesture, is present all over the world in over 10 million copies.
The collaboration with TERENZI began in 2007 and lasted several years.
Soft lines, deliberately rounded to eliminate sharp edges, Premiapri Nova combines innovation, ergonomics and design. It has a pleasant and familiar shape, which has been able to revolutionize the door opening system.
It is a patented system that must necessarily comply with repeated analyses and checks. Our company is the guarantor of the very high standard that international laboratories have established. For its realization, therefore, meticulous planning, applied research, continuous quality control are required: this is the working environment that we can offer.
TERENZI carried out the prototyping and the pre-series and started industrializing the product in large batches, corresponding to 300,000 units a year.
TERENZI gives the client the best solutions, qualitatively superior materials and consolidated know-how.
The product is available on the market in a wide variety of finishes and colours, and for this reason the company has demonstrated further production flexibility in fulfilling all the requested versions.
Premiapri Nova was created in three different metals – electrolytic galvanized iron, brass and AISI 304 stainless steel with some mechanisms inside the core.
According to programmed production batches, the product was made by shearing, using a mold designed internally by the Technical Office and built in the Tooling Department. The shearing iron draws the shape of the knob in succession with a transfer system and in further movements the shearings necessary to complete the action. In 12 distinct steps, the material is deformed and worked until the ideal shape is reached at the 7th station, the most interesting as it allows the final operations that give the object its spherical shape; the surface must be absolutely smooth to give maximum comfort to the handle. Here the deformation of the opening ends through a spheroidal matrix, which wraps around the opening of the knob.
The last steps concern the shearing of the back, the printing of the client's logo and, thanks to a cam system, and the lateral opening of the window too, in which the open-close button is inserted.
The operating instructions and the qualitative assembly procedures verify in particular the aesthetic and dimensional aspects.
