Surface and heat treatments improve the technical and/or aesthetic characteristics of the turned item based on the customer's requirements. In the mechanical industry, these treatments act on both the structure (heat treatments) and the protection or aesthetics (surface treatments) of the article. Such processes allow the item to adapt to its intended use and the environment conditions it will be subjected to.
Thanks to the historical collaboration with our partners, the most reliable in the field, we are able to offer an excellent service according to the customer's needs.
All the treatments are tailored according to the customer's needs.
The most needed services are:
Heat Treatments
Heat treatment is a controlled process used to alter the microstructure of metals and alloys such as steel and aluminium to impart properties which benefit the working life of a component, for example increased surface hardness, temperature resistance, ductility and strength.
We collaborate with Bodycote, a global leader in heat treatments.
Surface treatments
In Guerrini we handle many surface treatments, such as:
Zinc-coating
The items are subjected to a special galvanic process where a zinc coating is applied to protect them from "galvanic corrosion".
Our partnership with Gaser Group for galvanizing guarantees a prompt and reliable service.
Chrome-plating
The treatment consists in coating the item with a thin layer of chromium. Applied electrolytically or chemically, this coating gives a shiny, polished appearance to the items, while also protecting them from corrosion and increasing surface hardness.
Burnishing
Burnishing is a chemical surface treatment for blackening metal parts such as iron, brass, aluminum and carbon steel. It improves the aesthetics of the part and makes it immune to corrosion from weathering and substances.
Having an item subjected to burnishing improves its aesthetic characteristics and increases its strength and durability.
