Official Partner Maniglieria

Since 1911 Olivari has been manufacturing door handles at its own factories in Italy where the entire production process takes place. Starting with brass billets, the handles are forged, milled, polidhes, buffed, chrome- plated and hallmarked with a laser.

Throughout the 100-plus years of its manufacturing history, olivari has earned distinction for the quality of its products and the reputation of its brand. From generation to generation, the Olivari family has passed down the attention for detail, the quest for innovation, and above all, a passion for working to high standards.

Production Cycle

A distinctive feature at Olivari is the fact that the entire manufacturing process takes place exclusively at the Olivari factory in Borgomanero, northwest of Milan. Olivari products are not just in Made in Italy, they are Made in Borgomanero, Made in Olivari. This special feature ensures constant high quality, dependability and durability.

Made only in brass, Olivari products go through a precise sequence of phases: hot forging and shearing, mechanical processing, grinding, vibratory finishing, polishing, galvanic deposition, physical vapour deposition (PVD) and laser marking. In addition, all the technical components made in resin, brass sheet and steel sheet are forged and assembled in the same factory. 
Every phase of the production cycle is meticulously controlled to guarantee contant quality over time.

Brass, Chromium plating and Superfinishing

BRASS: Olivari uses only titrated and certified brass, an alloy made of copper and zinc. The shapes are obtained by hot forging and mechanical processing with swarf removal. These specific technologies allow olivari to obtain products devoid of porosity and inclusions. This guarantees superior mechanical resistnace. With these apposite measures, Olivari obtains the optimum conditions of preparation for the metal depositions of chromium plating and physical vapour deposition coatings under high vacuum.

CHROMIUM PLATING: The galavanisation process of applying metallic coats of nickel and chrome makes the product abrasion-resistant and corrosion-resistant. Olivari's chromed products offer corrosion protection for over 1000 hours of exposure to salt spray, and possess surface hardness equal to 800 micro Vickers.

SUPERFINISHING (Phisical Vapour Deposition): It is applied to products that have already been chromed, in order to obtain maximum resistance to wear and tear. In fact, PVD increases the surface hardness to three times that of chromium plating. Since 2004 Olivari has been using this technology, wich has the additional benefit of offering metallic colours that cannot be produced with traditional galvanisation. PVD coating has exceptional performance in stability and longevity of the colour, making the products last and last

Studio Olivari draws the Diana Barley handle

Guilloche is a decorative engraving technique that uses special lathes. Guided manually, these machines draw a precise, intricate, repeated pattern on the metal surface.Barley pattern, with engraving similar to grains, applied on Olivari best-seller Diana gives to the handle a shiny sophisticated allure.

Do you need help with assembly? Watch the video.

The illustrative video on the side shows in a few seconds how to assemble a dk type window handle. 90% of the dk handles on our shop already have the mechanism pre-installed, so we will proceed to insert the entire handle of the frame. While in case the mechanism is separated from the handle, you will be able to follow all the steps of the video.This is the only difference you might see from manufacturer to manufacturer. Therefore just arm yourself with a  screwdriver and patience.
