First, raw materials like basalt and dolomite are selected (with strict checks on indicators such as basalt’s silicon dioxide content) and proportioned, and additives like binders or water repellents are added as needed.
The prepared raw materials are then melted in a high-temperature furnace at 1400℃-1600℃ into uniform liquid, with impurities and bubbles removed to ensure purity.
Next, the molten liquid is turned into rock wool fibers via high-speed centrifugal equipment (stretched thinner by high-speed airflow), which then settle into a fiber felt on a mesh belt under negative pressure.
After spraying a binder (e.g., phenolic resin) on the felt, it is cured in a furnace at 180℃-250℃ for 10-30 minutes to form solid rock wool boards.
Finally, the cured boards are cut to specified sizes, inspected for appearance and physical properties (e.g., density, thermal conductivity), and qualified ones are packaged and stored.

1. Precise Customization to Adapt to Diverse Scenarios
Different application scenarios of rockwool boards have significant differences in requirements for specifications, performance, and forms. The OEM model relies on the factory's flexible production lines to customize products according to customer needs, eliminating the need for customers to build their own production lines or adjust parameters. It efficiently meets the needs of different scenarios, especially suitable for personalized orders from small and medium-sized customers.
2. Cost Reduction & Light Investment to Alleviate Operational Pressure
The production of rockwool boards requires high investment in equipment and technology. Through OEM cooperation, customers do not need to bear heavy asset investment and can concentrate funds on core businesses. Factories reduce unit costs through large-scale raw material procurement, and the bulk OEM price is more advantageous, reducing customers' capital pressure and operational risks.
3. Mature Technology to Ensure Stable Quality
Formal OEM factories have complete production and quality control systems, with standardized processes from raw material selection, production parameter control to quality inspection. Relying on mature experience, they stably produce products that meet standards or customer requirements, avoiding quality fluctuations caused by immature technology.
4. Resource Integration to Improve Response Efficiency
Factories have complete supply chains and multi-production-line capabilities, enabling rapid raw material deployment and shortened delivery cycles. They also support small-batch trial production, facilitating customers to verify market feedback, adjust product parameters, and flexibly respond to policy changes and market demand fluctuations.
5. Resource Sharing to Lower Market Access Threshold
The OEM model allows sharing of the factory's existing industry certification qualifications, saving customers the time and cost of applying for certifications. At the same time, factories provide technical support to help optimize product solutions, assisting customers in quickly entering the high-end market and enhancing competitiveness.

High-Performance Upgrade: Enhancing Core Functions and Environmental Adaptability
Focusing on the core performances of rockwool boards (thermal insulation, fire resistance, compression resistance), R&D aims to break through parameter limits and improve stability. It optimizes centrifugal cotton-making processes to reduce thermal conductivity to below 0.040W/(m·K); explores composite formulas of basalt and high-temperature-resistant mineral fibers for stability above 800℃; and develops high-efficiency hydrophobic modification technologies to increase hydrophobic rate to over 99% for humid areas.
Green Environmental Protection: Promoting Full-Lifecycle Sustainability
Driven by the "dual carbon" goal, R&D moves toward low carbon and resource recycling. It reduces high-energy-consuming basalt usage, explores industrial solid waste (steel slag, fly ash) replacement (with over 30% dosage); develops low-temperature curing processes (lowering curing oven temperature to 160-180℃) and uses formaldehyde-free adhesives; and breaks through rockwool recycling technologies to reuse waste boards.
Functional Composite: Expanding Diverse Application Scenarios
Through "rockwool + other materials" composite innovation, it endows rockwool boards with more functions. It develops rockwool-PP/PE composite boards for chemical equipment and marine ships, and rockwool-gypsum/cement composite boards for interior partitions. It also researches functional coatings (antibacterial, antistatic) for hospitals, food factories and electronic cleanrooms.
Shape & Process Innovation: Adapting to Scenario Needs and Production Efficiency
It researches irregular and lightweight rockwool products: arc/curved/modular boards for non-planar scenarios, and lightweight boards (density below 60kg/m³) for old building renovation. In processes, it upgrades intelligent production with AI control systems and develops continuous composite production lines for integrated forming with facing materials.
Customization for Segmented Scenarios: Matching Field Demands Precisely
It develops specialized rockwool boards for different industries: thin boards (30-50mm) for prefabricated buildings, high-temperature-resistant and anti-vibration boards for industrial equipment, and noise-reducing boards (sound absorption coefficient ≥0.8) for highway sound barriers and rail transit tunnels.
