Mold Splitting Principles for Complex GRC Shapes Explained: Qinglong's Modular Thinking Improves Production Efficiency

The art of mold parting is the key to simplifying the production of complex shapes; scientific principles balance efficiency and precision. The parting of complex GRC shapes directly affects production efficiency, component precision, and installation convenience. As a professional manufacturer with a GRC production capacity of 600,000 square meters, Qinglong Group has summarized a set of scientific parting principles for complex GRC shapes through the Shanghai Qingpu R&D project and the Sichuan Panzhihua Third-Front Construction Culture project, achieving efficient and precise realization of complex shapes.

#Shape Integrity Principle: Preserving the Core Design Form The primary principle of parting is to ensure shape integrity and avoid splits that would damage the core design concept. Through BIM 3D modeling, the Qinglong team analyzes the structural features of complex GRC shapes and sets split joints in non-focal visual areas and sections under less stress. In the Sichuan Panzhihua Third-Front Construction Culture project, for GRC curtain wall panels with a chiseled stone effect, the splits follow the natural texture lines, which ensures both the feasibility of component production and the artistic beauty of the overall shape.

#Production Feasibility Principle: Adapting to Processes and Equipment Parting must fully consider production processes and equipment capabilities to ensure components can be produced and demolded easily. Based on the equipment dimensions of its production workshops, Qinglong Group splits large complex components into standard modules of no more than 6m×3m, facilitating mold machining and component curing. For complex forms such as double-curved surfaces and hollow-out designs, segmented mold designs are adopted to reduce mold-making difficulty while ensuring damage-free demolding. In the 16,012-square-meter GRC curtain wall project in Qingpu, Shanghai, this principle increased production efficiency by more than 30%.

#Installation Convenience Principle: Reducing On-Site Construction Difficulty Parting design must also address on-site installation needs and reduce the difficulty of work at heights. When splitting components, the Qinglong team reasonably sets lifting points and connection joints to ensure component weights match the hoisting equipment. Meanwhile, modular splicing designs allow components to be quickly positioned and joined on site. In the 19,800-square-meter GRC curtain wall project at Xiangshan Science and Technology Park in Longhua, Shenzhen, optimizing the parting scheme shortened the on-site installation schedule and reduced construction safety risks.

The parting of complex GRC shapes is a key link connecting design and realization. With modular thinking at its core, Qinglong Group integrates parting principles with project realities, achieving a win-win between production efficiency and shape precision. Backed by 28 years of full-chain service experience, Qinglong has become the preferred supplier for complex GRC shape projects and will continue to optimize parting technology, delivering efficient realization solutions for more creative shapes.
