Materials

The quality of the materials is an essential part of the manufacturing of the pen. The materials guarantee durability and attractiveness. The traditional processing of celluloid, acetate and hard rubber are alternated with the creation of exclusive resins that Stipula develops in their laboratories with casting and melting processes.

Modeling

Modeling and prototyping of details is the basis of the pen's originality and beauty. It is made through a constant dialogue with tradition and according to manual methods. Here the mother piece takes shape gradually and according to a process of revision and constant improvement of the detail.

Mechanical processing

The details of the pen are hand-made. With the aid of the lathe and other machine tools, the material is shaped. The components of the pen are processed with very strict clearances to allow their assembly according to criteria of great accuracy and resilience. The pen, although an ancient artifact - nearly one hundred and fifty years old now - is in fact a precision instrument.

Goldsmith manufacturing of the metal trims

The metal details of the Stipula pen are obtained with goldsmith techniques, as ancient as the human civilization, one by one. The bronze, silver, gold and platinum casting takes place starting from a wax model. The molten metal is then finished by hand and calibrated to exacting measure to ensure it can be assembled with other mechanical parts.

HAND ASSEMBLY OF THE PEN

The components of the pen, once finished on the surface, through the hand polishing and the electric coating that keep them fresh and shiny over time, are sent to the final assembly operations. Here at a specific assembly and testing desk, equipped for this purpose, the last operations are done which ensure the functioning of the pen, up to the writing test and the definitive set-up of the nib.

HAND MANUFACTURING OF NIBS AND INK FEEDERS

The Stipula nibs are hand manufactured according to the dictates of the Italian nib masters of the 30s. With original equipment of the time (formerly Globus – Bologna). Starting from the melting of the virgin metal up to the lamination, to the forming of the lamina and to the refining of the iridium alloy tips, individually welded under an electric arc. Flexible nibs suitable for exalting expressiveness the so called “Stiflex”; or stronger and precise like the old Manifold nibs or simply very soft like the “Edredon” in tungsten-silver alloy. The Stipula nib is laminated with precious and semi-precious alloys with specific gradients of thickness; it is passed under the rolling mill to obtain the shape of the lamina; follows the shaping, the welding of the tip - a sphere of very hard and resistant material - the cutting of the tip with micrometric saws and the tip refining, to obtain the type of line and angles desired in the writing.As a key supplement to nib making, thanks to the ancient Globus equipment Stipula has also recovered the manufacture of ebonite feeders, one of the most necessary parts for creating excellence in fountain pens.

HAND MINIATURE PAINTING

Manual skills have different ways of expressing themselves. Sometimes blatantly exhibited, as in the wealth of details of a large overhang casting, or in a chisel or burin decoration, where even the Master's breathing affects the plastic rendering of the work. Other times, that ability of the hand is applied to less ostentatious solutions but equally capable of stimulating the senses. This is the case of the artistic miniature with which Stipula makes its pens unique. An ancient technique of over a thousand years that evolved from ancient illuminated manuscripts to eighteenth-century ivory jewels and now applied to the world of Stipula writing.
