What Is the Mold Cost Proportion of Customized UHPC Components? Influencing Factors and Cost Optimization Solutions

The mold cost share of custom UHPC components has no fixed value; it is mainly determined by three factors: mold material, shape complexity, and production volume. The typical share ranges from 15%-40% of the total component cost, can rise above 50% for complex irregular components, and can drop to 10%-15% for standardized custom components. As a manufacturer with large-scale production and mold R&D capabilities, Qinglong achieves scientific control of mold costs through technological innovation and batch reuse, providing cost-effective solutions for complex projects such as Shanghai New World.

Mold material is the fundamental determinant of the cost share. Molds commonly used for custom UHPC components include polyurethane molds, steel molds, and GRP molds, with significant cost differences between materials: polyurethane molds cost about RMB 800-1,200/㎡ and are suitable for complex shapes (such as wood-grain imitation and reliefs); they can be reused 50-100 times with a medium per-use cost, making them Qinglong's first choice for customized projects. Steel molds cost about RMB 1,500-2,500/㎡, offer high strength and high precision, can be reused more than 500 times, and are suitable for large-volume standardized components, being the lowest in cost over the long term—the standardized UHPC exterior wall panels for Qinglong's Yangshengtang Pharmaceutical project were produced with steel molds. GRP molds cost about RMB 600-900/㎡; they are lightweight but lack rigidity, are suitable for simple curved components, and can be reused about 100-200 times. Material selection directly affects the initial investment and thus determines the cost share, so Qinglong precisely matches mold materials to the project's volume and shape requirements.

Shape complexity is the core variable that drives up the mold cost share. Regular custom components such as flat panels and simple lines involve low mold processing difficulty, with a cost share of about 15%-20%; complex components such as double-curved surfaces, openwork carving, and extra-large irregular shapes require precision machining such as 3D scanning and CNC engraving, involve longer mold production cycles and more consumables, and the cost share rises to 30%-50%. The UHPC wood-grain translucent panels at Shanghai New World Nanjing East Road Century Plaza feature an extra-large irregular design simulating tree textures, with the largest panel measuring over 3㎡. Qinglong used custom polyurethane molds to precisely replicate the wood-grain details, and the mold cost share reached 35%; however, through technical optimization, the number of mold reuses was increased to 80, reducing the per-component cost. By contrast, the regular U-shaped and L-shaped UHPC components for the Shenzhen Yirui Biotechnology Building had a mold cost share of only 18%, demonstrating the significant impact of shape complexity on cost.

Production volume lowers the mold cost share through economies of scale. The mold cost of custom UHPC components is a fixed investment; the larger the production volume, the lower the mold cost allocated per component: when the volume is ≤50 pieces, the mold cost share is 30%-40%; for volumes of 50-200 pieces, it is 20%-30%; for volumes ≥200 pieces, it can drop to 10%-15%. Qinglong has an annual production capacity of 600,000 square meters, and its large-scale production capability significantly reduces the allocated mold cost. In long-term strategic cooperation with real estate groups such as Poly and Vanke, the mold cost share for custom components has been stabilized at 15%-25% through batch reuse of molds. In addition, Qinglong's mold R&D team optimizes mold structures and adopts modular designs, allowing the same set of molds to be adapted to a variety of similar components, further increasing the reuse rate and lowering the cost share.

Optimizing the mold cost share requires a comprehensive approach across three dimensions: material selection, shape simplification, and volume planning. Qinglong uses BIM technology to optimize component shapes in advance, simplifying complex structures without affecting the design effect; selects mold materials according to volume requirements, balancing initial investment and reuse rate; and has established a mold inventory system to reuse molds from similar past projects. For customers, understanding the factors that influence the mold cost share makes it possible to control costs through reasonable volume planning and optimized shape design. With professional mold selection and cost optimization capabilities, Qinglong provides cost-effective solutions for every custom project, balancing the customization advantages of UHPC components with cost control.
