Custom UHPC Component Mold Cost Proportion Analysis: The Cost Code from Standard to Special-Shaped Molds

Customization is the core advantage of UHPC components, but mold cost has always been a focal point for owners and designers. As a custom UHPC manufacturer with a production capacity of 600,000 square meters, Qinglong Group draws on 28 years of hands-on experience to break down the composition logic and proportion patterns of mold costs, providing a professional reference for project cost control.

I. Core Proportions: Range Distribution of Mold Costs????

The mold cost proportion of custom UHPC components is not a fixed value; it depends mainly on shape complexity and production batch, with an overall range of 15%-50%. Conventional straight components (such as flat cornices) have a mold cost proportion of 15%-25%; double-curved, hollowed-out, or artistic components account for 30%-50%; super-large special-shaped components (single units exceeding 10㎡) can reach as high as 50%. In Qinglong's Shanghai New World Nanjing East Road Century Plaza project, wood-effect translucent UHPC components used special polyurethane molds, pushing the mold cost proportion to 40%; however, through mold reuse, costs on subsequent similar projects were reduced by 18%.

II. Influencing Factors: Three Dimensions That Determine Mold Costs

1. Mold material selection: Conventional components use GRP molds at a cost of about 80-150 yuan/㎡; complex shapes require steel or silicone molds, with costs rising to 300-600 yuan/㎡. For the U-shaped UHPC curtain wall panels custom-made for Yangshengtang Pharmaceutical's Hangzhou Industrial Park, Qinglong selected GRP molds, keeping the mold cost proportion at 22%.

2. Shape complexity: Molds for straight-line components can be reused 30-50 times, while special-shaped component molds can only be reused 5-15 times. The double-curved UHPC components of the Guangxi New Media Center each feature a unique shape, resulting in low mold reuse and a cost proportion of 45%.

3. Production batch: When the batch exceeds 1,000 pieces, the mold cost proportion can drop to 15%-20%; small-batch customization (fewer than 100 pieces) raises the proportion to above 35%. In strategic cooperation projects with developers such as Poly and China Overseas, Qinglong keeps the mold cost proportion stable at around 20% through large-volume purchasing.

III. Cost Optimization: Qinglong's Full-Process Cost Reduction Solution

Qinglong optimizes mold costs through three strategies: first, modular design, which breaks complex shapes into standard modules for assembly—such as the UHPC inclined panel components of the Shenzhen Yirui Biotechnology Building, where mold reuse increased by 40%; second, material upgrades, adopting new composite material molds that balance precision and durability; third, digital modeling, using BIM technology to optimize mold structures and reduce material waste. In the Ouargla Hotel project in Algeria, 50mm-thick hollowed-out UHPC panels saw their cost proportion fall from 38% to 32% through mold optimization.

Mold cost is one of the core costs of custom UHPC components; reasonable shape design and batch planning can effectively control the proportion. As a national specialized, refined, distinctive and innovative enterprise, Qinglong leverages patented mold technology and large-scale production advantages to optimize mold costs while ensuring faithful shape reproduction. Whether for conventional components or artistic special-shaped pieces, Qinglong delivers highly cost-effective custom solutions.
