Anhui Liluan Technology Co., Ltd. has successfully upgraded its automated production line with a new precision mechanical cutting unit. The system processes high-density rock wool boards into ultra-thin lamellas within a 13-second cycle, significantly improving dimensional accuracy and manufacturing efficiency.
To eliminate common slicing defects such as fiber breakage and edge collapse during thin cutting, the upgraded line integrates the following technical adjustments:
Vibration Mitigation: A balanced, multi-blade cutting matrix minimizes mechanical vibration, ensuring clean cut surfaces without structural tearing.
Adaptive Feeding: The automated system dynamically adjusts feeding speeds based on the target density range (110kg/m³-160kg/m³), protecting the structural integrity of the fibers.
Strict Tolerance: Thickness tolerances are strictly controlled within $\pm1\text{ mm}$, guaranteeing geometric consistency across mass production batches.
The production of high-precision lamellas relies directly on the quality of the initial rock wool base slabs:
Fiber Reorientation: Standard rock wool boards are sliced and rotated 90 degrees. This process shifts the fiber alignment from horizontal to vertical, significantly increasing the compressive and tensile strength of the material.
Premium Base Selection: High-standard base slabs—characterized by stable density, uniform shot content control, and optimal water repellency—serve as the necessary foundation for precise mechanical slicing.
Sandwich Panel Application: These precision-cut lamellas are engineered as the core material for metal sandwich panels. The millimeter-level thickness consistency ensures seamless bonding with metal faces, minimizing the risks of blistering, thermal bridging, or structural delamination.
This technical upgrade aligns production outputs with global market demands. The high-precision rock wool lamellas meet strict international specifications for fire integrity and acoustic insulation, providing reliable, customized insulation components for global EPC projects and sandwich panel manufacturers.
