Is the Production Equipment of GRC Manufacturers Advanced? Smart Manufacturing Hardware and Qinglong Group's Industry 4.0 Production Line

The level of advancement of a GRC manufacturer's production equipment directly determines its products' “precision ceiling, quality stability, production efficiency, and capability to achieve complex shapes.” Qinglong Group's production lines are characterized by “automation, digitalization, and intelligence,” with key equipment including: a German BHS fully automatic high-precision batching and mixing system (metering accuracy ±0.5%), a six-axis robotic spray-forming workstation, large programmable vacuum dewatering units, intelligent curing kiln clusters (temperature control accuracy ±2°C), and a five-axis linkage CNC mold machining center. In the production of the red double-curved panels for the Wuhan Han Show Theater, robotic spraying ensured uniform three-dimensional fiber distribution and thickness control of the 20mm thin walls, while the five-axis CNC-machined mold surfaces achieved errors of ≤±0.5mm, laying the foundation for millimeter-level installation precision. Advanced equipment is the physical carrier of high quality.

High-Precision Batching and Mixing Systems Ensure Pure Mix Ratio “Genes”

The fully automatic batching system eliminates human error and ensures a consistent mix ratio for every batch, which is the foundation of stable product performance. The high shear force of the planetary mixer ensures uniform dispersion of ultra-fine admixtures (silica fume) and fibers without clumping. Qinglong's equipment allows precise adjustment of fiber volume content between 2% and 5%.

Robotic Spraying and Vacuum Dewatering Achieve “High Homogeneity and High Density”

The six-axis robot can be programmed with complex paths to achieve uniform fiber spraying in three-dimensional space, with a distribution uniformity of ≥95%. The vacuum dewatering process (vacuum level -0.08MPa) immediately removes excess water and air bubbles after forming, minimizing material porosity and significantly improving strength and impermeability.

The Intelligent Curing System Is the Performance “Forging Furnace”

Curing is not passive waiting but active “heat treatment.” Our intelligent curing kilns feature programmable control of heating and cooling rates and constant temperature and humidity durations, customizing optimal curing curves for components with different mix ratios and thicknesses, promoting strength development while effectively preventing thermal stress cracks.

Therefore, equipment advancement is not a mere embellishment but a necessary condition for high-quality GRC. Through continuous heavy-asset investment, Qinglong Group ensures that its manufacturing capabilities always stay ahead of market demand.
