Brizio Basi has been, during the last decades, a reference point in the design and construction of advanced vacuum systems dedicated to the glass processing sector and the production of abrasive finishing tools.
Our systems for the glass sector leverage several specialized technologies to improve both process efficiency and product performance:
High-Temperature Sulfur Treatment
This process enables the impregnation of abrasive tools, such as superfinishing stones, with sulfur to enhance lubrication and improve surface quality during glass machining operations.
Vacuum Impregnation with Liquid Sulfur (VPI)
Vacuum impregnation allows complete and homogeneous penetration of liquid sulfur into the ceramic binder that holds the abrasive grains. The result is an abrasive tool with superior technical properties and extended operational life.
How does this technology support glass manufacturers?
Superfinishing stones are essential for the final surface finishing and edge processing of glass products. The sulfur impregnation under vacuum and high temperature conditions creates a sliding film that acts as a lubricant between the abrasive stone and the glass surface.
Automated Impregnation Plants – Industry 4.0 Ready
Brizio Basi develops fully computerized impregnation systems equipped with PED-certified autoclaves and programmable recipes:
-
Working temperatures adjustable from 0 to 200 °C
