The Manufacturing Process for Hardboard eHow

Hardboard is manufactured using one of three processes wet processing, dry processing or wet/dry processing. Wet processing uses wet wood fibers to form wet mats for pressing. Dry processing uses dry fibers to form dry mats for pressing. Wet/dry processing forms wet mats that are dried before pressing.
