Calibration and Pre-Polishing Line
Marlin has a calibration and pre-polishing line that processes all the slabs it produces. The Calibration and Pre-Polishing Line is equipped with a 10-head Barsanti calibrator, with 6 heads for calibration and 4 for pre-polishing. After passing through the calibration line, the slabs can proceed directly to the polishing line or first to the resin coating line, depending on the needs of the specific project or the client.
Resin Coating Line
The resin coating line is equipped with Breton S.p.A. equipment, purchased by Marlin in November 2017. The process consists of coating the slabs with epoxy resin that fills the natural pores of the stone, resulting in a smooth, glazed surface.
All stages of the resin coating process are automated, from loading the slabs into the machine to their exit from the resin coating line.
The first step consists of drying the slabs, followed by the application of resin and catalyst. For pieces that require special care, this process can be done manually. Next, they are transferred to a vacuum chamber, which facilitates the penetration of the resin into the stone, thus increasing its resistance. The catalyst process involves placing the slabs in a second oven to accelerate and optimize the process. This oven has a capacity of 40 slabs simultaneously.
After drying, the slabs are transferred to the polishing line.
