Arauco to Replace MDF Line With Modern OSB Plant in Cholguán, Chile

Chile-based Celulosa Arauco y Constitución S.A. (Arauco), the world’s second-largest manufacturer of wood-based panels, has commissioned DIEFFENBACHER to supply an OSB plant to replace an existing MDF line at its Trupan site in Cholguán, Chile. The plant is scheduled to start production in the second half of 2026.

The DIEFFENBACHER scope of supply will range from the wood yard with debarking to the raw board handling, including pneumatic systems and plant electrics and automation.

Tito Jara, Composite Panels Corporate Industrial Director at Arauco, said:

“We operate eight production lines from DIEFFENBACHER, and they’re all running great. We’re very satisfied with all our equipment from DIEFFENBACHER. That’s why we chose DIEFFENBACHER for this brownfield project to convert our Trupan I MDF line into a state-of-the-art OSB line.”

Diego Coelho de Oliveira, Area Sales Director and Managing Director of DIEFFENBACHER do Brasil, said:

“It’s a special project for us, not only because we are happy to be working with our friends at Arauco again, but also because we will be building the new plant around the existing 10-opening press from 1988, which will remain at the center of the production line.”
