When many architects and clients first receive a Flexible Stone sample, they can’t help but pinch and bend it, and then ask the same question: “It feels like leather but looks like real stone. How on earth is this made? Is there plastic mixed inside?”
In fact, there is not a single drop of plastic in Flexible Stone. As a leading China MCM Flexible Stone Manufacturer, Guangdong Fortune Stone New Material Co., Ltd. will take you into our smart factory today to uncover the manufacturing secrets behind this “bendable stone.”
Step 1: Unveiling the Core Formula of “Turning Stone into Gold”
The essence of Flexible Stone is a “Modified Inorganic Powder Composite Building Decorative Sheet.” Its magic lies in the perfect microscopic recombination of inorganic minerals and polymer emulsions. Our standard formula contains four core components:
- Calcium Sand (55%): This is the “skeleton” of the Flexible Stone, providing ceramic-like hardness and wear resistance.
- Calcium Powder (35%): Responsible for filling microscopic pores and ensuring the density and flatness of the material.
- Acrylic Emulsion (10%): This is the soul of its “flexibility.” It acts like an invisible net, wrapping all the mineral powders together.
- Balance (Special Additives): Used for dispersion, defoaming, flame retardancy, and UV resistance.
(Note: It is precisely this 10% polymer emulsion technology that has generated Fortune Stone’s multiple core invention patents, including high flexibility, non-migration, and high breathability.)
Step 2: Ten Rigorous Processes, An Industrial Symphony on the Assembly Line
Walking into the production workshop, from a handful of dry powder to a beautiful piece of stone, it must undergo ten precise processes:
- Slurry Mixing: Blending inorganic minerals and emulsions in a high-speed mixer, ensuring it is uniform and bubble-free.
- Spraying & Forming: Automated nozzles evenly spread the slurry onto silicone molds with natural stone textures.
- Drying & Curing: Entering the core temperature-controlled tunnel kiln. This is the crucial step that determines success or failure (see details below).
- Demolding: The formed Flexible Stone is gently peeled off the mold by robotic arms, just like leather.
- Offline Transfer: Semi-finished products enter the next process.
- Precision Cutting: High-precision equipment cuts them into standard sizes like 1200*3000mm, with flat, burr-free edges.
- Digital Printing: High-definition inkjet technology gives them realistic travertine, rammed earth, or wood grain colors.
- Intelligent Quality Control: AI visual inspection equipment and manual double verification eliminate any products with minor color differences or defects.
- Eco-friendly Packaging: Palletizing and film wrapping to ensure safety during transportation.
- Loading & Shipping: Dispatched to global Facade Retrofit or high-end commercial project sites.
Step 3: Core Process Revealed — The Art of Three-Zone Temperature Control and Speed
In the entire assembly line, “Drying” is the link with the highest technical barrier. If the temperature is too high, the surface will skin over and internal moisture cannot escape; if too low, it cannot be shaped. To achieve extreme physical properties, we adopt a Three-Zone Gradient Temperature Control System:
- Zone 1 (70°C): Gentle preheating. Allows moisture to migrate from the inside of the material to the surface.
- Zone 2 (90°C): Medium-temperature shaping. Prompts the acrylic emulsion to undergo cross-linking and curing, forming a tough network.
- Zone 3 (100°C): High-temperature efficiency. Thoroughly dries and locks in physical strength.
Simultaneously, the conveyor belt speed is strictly controlled at 0.4 ~ 0.8 meters per minute (m/min). This seemingly turtle-like speed is actually for precisely controlling the moisture content. If producing thicker boards (e.g., 3mm), the system will automatically slow down; if producing 2mm thin boards, it speeds up appropriately. This precise control ensures that every piece of Flexible Stone leaving the factory possesses a -30°C freeze-thaw resistance and a A2-s1, d0 fire resistance standard.
Conclusion: Technology Reshapes the Beauty of Nature
From inorganic powder to Flexible Stone, this is not just a change in physical form, but a deep leap in materials science. It is the relentless perfection of the formula, processes, and parameters that endows Flexible Stone with its many hardcore attributes: ultra-lightweight (3.96kg/㎡), fireproof, weather-resistant, antibacterial, and antiviral.
