For its 65th anniversary, Guglielmi opened the doors of the plant at Grignasco in the Novara region for the first time to journalists, to narrate its history through images, historic machinery and a guided tour of the production processes that lead to the creation of a faucet

The products of Guglielmi come from ideas, ingenuity and skill. Every single process in the production cycle is controlled and analyzed down to the smallest details. In the phase of invention and design the styling division analyzes the forms and materials that will go into a faucet. The technical division handles the engineering of the product, thanks to the use of 3D software.

The first stop is the foundry: during this phase, the raw body of the faucet is created. The initial process has to do with the creation of the so-called cores used to obtain holes in the casting, i.e. the parts that are not to be filled with liquid metal (molten brass). The cores are formed by earth or sand mixed with aggregate, formed by negative molding.

The second passage involves the creation of shells or the mold inside which to pour the metal (molten brass). The core is placed inside the shell to lead up to the pouring process. The molten metal is drawn from the furnace by means of a ladle and poured into the mold through the pour canal. When it has solidified and cooled, the raw faucet is extracted from the mold, and vibration shakes out the sandy core to obtain the spaces in which the water can flow.

In the turning shop the process of industrial production proceeds into mechanical workmanship, done by removing excess metal. The turning involves rotation of the piece and mostly rectilinear movement of the tool (while in milling and drilling the tool can have a rotating motion).

Cleaning / grinding / polishing are metalworking processes that prepare the pieces for the true finishing involving nickel-plating, chrome-plating and gilding. The purpose of grinding and polishing is to remove microscopic irregularities and to make the surface as smooth as possible, so its reflection of the light will be more uniform.

Finally, chrome-plating / coating: this is a chromium covering of a product, done with electroplating. The faucets are ready to be chromium-plated or coated in the desired finish.

Quality control, assembly, testing, packaging and shipping complete the production cycle.
