Batching: Ingredients like cement , silicate sand , cellulose fibers , synthetic fibers, and additives are precisely weighed and mixed.
Slurry Formation: Water is added to form a homogeneous slurry in a high-speed mixer.
Hatschek Process : The slurry is deposited onto a moving sieve, where vacuum dewatering forms thin layers that are wound to the desired thickness.
Flow-on Process : The slurry is poured onto a conveyor belt, leveled, and partially dewatered by the felt.
Cutting: An automated cutting machine trims the sheets to standard sizes (e.g., 1220×2440 mm) or custom dimensions.
Stacking: Boards are stacked on pallets for further curing.
The wet sheet passes through a pre-press to remove excess water and compact the structure.
Pre-curing begins in a controlled environment to enhance green strength.
Boards are loaded into autoclaves and subjected to high-pressure steam (8–12 bars, 180–200°C) for 8–12 hours to achieve full strength and durability.
Drying: Excess moisture is removed in drying chambers.
Surface Treatment: Boards may be sanded, coated, or textured for specific applications (e.g., paint-ready or wood-grain finishes).
QC Checks: Density, thickness, flexural strength, and dimensional stability are tested.
Packaging: Boards are wrapped in protective film, labeled, and prepared for shipping.
Finished products are stored in a dry warehouse before distribution.
