What Is the Mold Cost Proportion for Custom UHPC Components?

The mold cost of customized UHPC components is an important part of total project investment, directly affecting economic viability and feasibility. Based on 28 years of customized production experience, Qinglong Group holds that mold costs typically account for 15%-25% of the total cost of customized UHPC components, and may rise to 30%-40% for complex shapes or small-batch projects. Through mold optimization, standardized design, and mass production, Qinglong Group keeps the mold cost proportion within 20%, providing customers with highly cost-effective customized solutions.

Mold costs are significantly affected by complexity. Simple flat-panel molds cost about RMB 200-500 per square meter, while double-curved or openwork molds can reach RMB 800-1,500 per square meter. In the "Chinese Red Lantern" project for the Wuhan Han Show Theatre, Qinglong Group used CNC-machined epoxy resin molds, with costs accounting for 18%; through mold reuse (service life ≥200 uses), the amortized proportion dropped to 12%. Mass production is key: when a single batch reaches ≥1,000 square meters, the mold proportion can be optimized to below 15%. Small-batch customization (e.g., artistic components) carries a high proportion, which customers need to weigh carefully.

Material selection affects mold expenses. Steel molds require a high initial investment (RMB 1,000-2,000 per kilogram) but have a long service life (over 5,000 uses), making them suitable for large batches. In a Shenzhen project, Qinglong Group used steel molds to produce standard panels, with mold costs accounting for only 10%. Silicone molds are low in cost but have a short service life (100-200 uses), making them suitable for complex small batches. Early involvement at the design stage for optimization and reduction of non-standard elements can lower mold costs by 10%-15%.

Scientific management keeps costs under control. Qinglong Group uses BIM technology to optimize component segmentation and reduce the number of mold types. Building a mold library and reusing standard molds saves expenses. Customized projects require comprehensive evaluation to select the optimal solution.
