The company was established in Milan in 1949, under the name of Mida, by the chemical engineer Erminio Paronitti. It was acquired by Giorgio Pozzi in 1985. In 1988, the company moved to its current headquarters in Cornegliano Laudense (Lodi) where, since 2007, it has been focusing exclusively on subcontracting, offering multiple proposals that represent both tradition and innovation in the field of wear-resistant, anti-corrosive and anti-stick coatings: flash hard chrome, hard chrome plating, DLC (Diamond Like Carbon), “anti-sticking” silicon oxide. These treatments are applied to parts in steel, stainless steel, aluminium, brass, and copper intended for use, above all, in plastic moulding sectors, the food industry, precision mechanics, packaging and pharmaceuticals.
“Anti-sticking” silicon oxide, economical and technically advanced compared to traditional fluoropolymer treatments, is a permanent hydrophobic coating that drastically reduces surface wettability and sticking.
5 treatments for 1,000 applications
Every Techno Mida treatment has very distinct characteristics and, in some cases, the key to success is to combine them to create a double coating in which the second makes up for what the first is lacking, a possible “marriage” between flash hard chrome or hard chrome plating and DLC, flash hard chrome or hard chromium plating and silicon oxide, and Flash hard chrome and anti-sticking silicon oxide.
DLC is the harder, hard chrome the thicker, and silicon oxide the more anti sticking
• Flash hard chrome: deposition temperature: 65°C; layer thickness: 1° 10 µm; hardness: 1200 Vickers
• Hard chrome plating: deposition temperature: 65°C; layer thickness: from 0.01 mm to several tenths of a millimetre; hardness: 68 Rockwell.
• DLC: deposition temperature: 120°C; layer thickness: from 2.5 to 4 µm; hardness: 2500 Vickers.
• Silicon oxide (SiOx): deposition temperature: 60-100°C; layer thickness: from 0.5 to 4 µm; hardness: 400-500 Vickers.
• Anti-sticking silicon oxide: deposition temperature: 80-120°C; layer thickness: from 0.5 to 4 µm; hardness: 1200 Vickers.
All the treatments by Techno Mida are direct contact food grade coatings.
