What Is the Mold Cost Proportion for Custom UHPC Components?

The mold cost share for custom UHPC components is typically 10%-25%, primarily determined by three factors: mold type, shape complexity, and production batch. For small batches with complex shapes (such as double-curved and hollow-out designs), the share can reach 20%-25%, while for large batches with conventional shapes it is only 5%-10%. Through mold reuse technology and automated processing, Qinglong can reduce the mold cost share for complex shapes by 5-8%.

I. Cost Share Differences Among Mold Types

Mold material directly affects cost share and reuse rate. Steel molds: cost share 8%-15%, reusable more than 500 times, suitable for large batches of linear and flat-panel custom components; the steel mold for Qinglong's linear UHPC decorative profiles has a cost share of 8%, amortized down to 3% after 300 reuses. GRP molds: cost share 15%-20%, reusable 50-100 times, suitable for double-curved and irregular custom components; the GRP mold for Qinglong's double-curved UHPC components has a cost share of 18%, dropping to 10% after 50 reuses. Silicone molds: cost share 20%-25%, reusable 30-50 times, suitable for high-precision textured and hollow-out custom components; the silicone mold for Qinglong's stone-textured UHPC components has a cost share of 22%. Wood molds: cost share 5%-8%, usable only 5-10 times, suitable for temporary custom samples or simple shapes; the wood mold for Qinglong's custom samples has a cost share of 6%.

II. Impact of Shape Complexity and Production Batch

Shape complexity and batch size are the key variables in mold cost share. Shape complexity: conventional flat-panel custom components have a mold cost share of 5%-10%; double-curved and twisted shapes account for 15%-20%; hollow-out, relief, and multi-curved composite shapes account for 20%-25%, with Qinglong's 12 ㎡ extra-large double-curved hollow-out UHPC components reaching a mold cost share of 23%. Production batch: for batches of ≤50 pieces, the mold cost share is 18%-25%; for batches of 50-200 pieces, it is 12%-18%; for batches of >200 pieces, it is 5%-12%; for Qinglong's UHPC cornice components produced in a batch of 300 pieces, the mold cost share drops to 7%. Machining difficulty: CNC-machined molds cost 30%-50% more than handmade molds, but offer 60% higher precision; complex shapes require CNC machining, which raises the cost share accordingly; all of Qinglong's double-curved molds are CNC-machined with precision reaching ±0.3 mm.

III. Qinglong's Mold Cost Control Solutions

Through technological innovation and process optimization, Qinglong effectively reduces custom mold costs. Mold reuse design: complex shapes are broken down into modular sections, and common modules can be reused across different projects, raising the reuse rate by 40% and reducing mold costs by 15%-20%. Material substitution: the optimal mold material is recommended based on batch size and shape; for small batches with complex shapes, a "GRP mold + partial silicone mold" combination is used, costing 8%-10% less than an all-silicone mold. Automated processing: CNC engraving machines and laser cutters improve mold processing efficiency and reduce labor costs, shortening the mold processing cycle by 30% and cutting costs by 10%-15%. Project cases: the custom UHPC curtain wall panels for the Shenzhen Yirui Biotech Building (batch of 200 pieces) had a mold cost share of 9%; the double-curved custom components for Shanghai New World Plaza (batch of 30 pieces) had a mold cost share of 21%, both below the industry average.
