Productora de Papel, SA de CV (Propasa), Mexico, has begun producing containerboard on its rebuilt PM 3. With the machine rebuilt by Voith, Germany, Propasa aims to increase production by up to 25%, producing nearly 500 metric tpd of board, while improving the final quality of its product.
The project's first part included the supply of a MasterJet Pro F/B headbox with ModuleJet II dilution control as well as the rebuild of the forming section, including a DuoShake that allows for greater homogeneity in the paper web formation. The reel and winder were also modernized. In a second step, the machine's dryer section was rebuilt. The second phase included the addition of two dryer sections to the machine, thereby increasing its speed.
Propasa also utilized Voith's basic engineering services for the machine's steam and condensate, lubrication, ventilation, and vacuum systems.
Shortly after startup, the machine was producing saleable board and there was a visible improvement in product quality. With this outcome, the company says it has taken an important step towards consolidating the group's growth in highly competitive markets such as Mexico and the U.S.
Propasa has been operating for more than 70 years, dedicated to the production of coated cardboard and liner, corrugated medium, and white top liner. In recent years, the company has expanded its production capacity with sales to markets in Mexico, the U.S., and Central America.
