The continuous mat from the forming station first enters a pre-compressor for initial compression (approx. 3:1 ratio) to remove air and increase green strength. The mat is then fed tension-free into the continuous press inlet. The continuous flat press consists of upper and lower endless steel belts and multiple heated platens. Hydraulic cylinders apply continuous, uniform pressure to the mat through the steel belts, while thermal oil circulation transfers heat to the mat, curing the adhesive under high temperature and pressure. The mat runs continuously from the inlet to the outlet, with thickness gradually compressed to the target value. Pressing pressure and temperature profiles are controlled in zones to ensure low internal stress and uniform density distribution. The cured continuous board strip exits the press, passes through a cooling carousel and edge trimming saws, then proceeds to post-processing.

Q: What are the main differences between the continuous flat pressing production line and the multi-layer press machine production line?
Answer:A continuous press line runs non-stop : the mat continuously enters the press, offering higher efficiency, better thickness uniformity, lower waste, and reduced energy consumption. A multi-opening press is batch-type : each cycle requires loading, closing, pressing, and unloading - resulting in longer cycle times and poorer thickness control, though initial investment is lower. For projects above 50,000 m³/year, a continuous press offers better overall value.
Q: How long does the steel belt last? Is the replacement cost high?
Answer:Under normal operation and maintenance, steel belt service life is typically 4-6 years. Steel belts are wear parts and replacement cost is significant. However, our design features modular belt joints, reducing replacement time to within 2 days. We also offer belt refurbishment services to extend service life.
Q: Can your company provide overseas installation and commissioning services?
Answer:Yes. We will send 2-4 senior engineers to the customer’s site to supervise installation, guide connection and debugging, conduct no-load and material testing, and provide systematic training for operators and maintenance staff. Service period is typically 3-6 weeks. The customer is responsible for visa, accommodation, and local transportation for the engineers.
Q: What are the requirements for raw materials on the production line?
Answer:Raw materials can include wood particles, sawdust, wood chips, crushed bamboo, straw, and other biomass. Recommended moisture content is 8%-12%, free of metal, stones, and other hard contaminants. We can provide corresponding preparation, drying, and gluing solutions based on the customer’s local raw material characteristics.
