Dongwha Addresses Challenging Fiber

The Korean company Dongwha is securing the longest MDF press in Asia with an 8 ft. x 47.1 m press from Siempelkamp for processing the demanding raw material, acacia.

In 2010 and 2015 VRG Dongwha, a joint venture of Dongwha International and the Vietnam Rubber Group (VRG), ordered two MDF plants from Siempelkamp, located in the south of Vietnam in the greater Saigon area. The new investment in a third Siempelkamp plant by Dongwha as an individual company will process specific resource deposits in northern Vietnam in the Hanoi area. Here, acacia is considered one of the most common tree species—ideal for improving soil quality, filtering pollutants and enriching the soil with nitrogen. However, the raw material acacia presents board producers with challenges due to its demanding fiber geometry.

With the ContiRoll Generation 9 NEO (New Entry Option), Siempelkamp developed a continuous press with extended highly flexible press infeed that ensures controlled deaeriation of the mat—important for reliable process stability at high production speeds, especially with special fiber geometries.

In addition to the forming and press line, board handling and a glue kitchen adapted to the raw material, the scope of supply also includes a dryer and an energy system from Siempelkamp subsidiary Büttner. Delivery/assembly will start in the third quarter of 2020 and commissioning is scheduled for the late summer of 2021.
