What Are the Production Challenges of Hollow-Out GRC Decorative Panels? Qinglong's Technical Breakthrough in GRC Hollow-Out Panels

The production challenges of openwork GRC decorative panels mainly lie in three areas: mold making, fiber distribution, and demolding operations. When the openwork ratio exceeds 30%, mold strength must be increased by 50%, fiber length shortened to 12-15mm, and demolding time extended by 30%. By optimizing the mix ratio and improving the process, the maximum openwork ratio can be raised to 60%.

An openwork GRC panel for a cultural arts center, with an openwork ratio of 45%, used reinforced molds (thickness increased to 10mm) and chopped fibers (length 12mm), successfully resolving the production challenges. Similar products from unverified manufacturers had a breakage rate as high as 20%. Through dedicated technical development, Qinglong GRC achieved a finished product rate of 98.5% for openwork panels.

Mold Reinforcement Design

Mold thickness increased to 8-10mm; stiffening ribs added to improve rigidity; these designs ensure mold stability.

Material Mix Optimization

Fiber length shortened to 12-15mm; proportion of chopped fibers increased; these optimizations improve formability.

Production Process Adjustment

Layered spray process; curing time extended to 36 hours; these adjustments improve the finished product rate.

Quality Control Standards

Openwork dimension deviation ≤1mm; edges intact and undamaged; these standards ensure quality.

Openwork panel production requires specialized technology. Qinglong GRC's mature processes achieve complex shapes.
