How Can Small and Medium-Sized Projects Reduce Mold Costs for Custom UHPC Components? Practical Optimization Solutions and Qinglong's Practice

For small and medium-sized projects (area ≤1000㎡, component quantity ≤50 pieces), mold costs account for a high proportion of custom UHPC component costs (up to 20%-30% of total cost), becoming a key factor restricting project implementation. Drawing on 28 years of mold R&D and production experience, Qinglong Group has summarized four major cost control solutions—"design optimization, mold reuse, material selection, and cooperation models"—helping small and medium-sized projects reduce mold costs by 30%-50% and successfully serving a large number of small and medium-sized commercial and landscape projects.

I. Design Optimization: Simplify Shapes to Reduce Mold Complexity

Standardized shapes instead of customization: split complex irregular components into standardized modules (e.g., straight segments + simple curves) to reduce the number of custom molds. Qinglong split complex double-curved components into 3 standard modules for a small commercial project, reducing mold costs by 40%. Reduce mold segmentation: where structurally feasible, increase the size of individual components and reduce the number of segments (e.g., combining four 1㎡ components into two 2㎡ components), cutting mold quantity by 50%. After Qinglong's optimization for a landscape project, mold segments were reduced from 8 to 4, lowering costs by 35%. Simplify decorative details: reduce overly complex openwork and reliefs (openwork ratio controlled within 30%, relief depth ≤10mm), and replace three-dimensional textures with surface coatings, acid washing and other processes. Qinglong simplified relief details for a residential community's landscape components, reducing mold machining costs by 25%.

II. Mold Reuse: Improve Mold Turnover Efficiency to Share Costs

Universal frame + replaceable modules: molds adopt a "universal steel frame + replaceable curved surface/texture module" design; the universal frame is reusable (≥50 times) and only the replaceable modules are customized. Qinglong provides this solution for small and medium-sized projects, reducing mold costs by 30%-40%. Multi-project mold sharing: if multiple small and medium-sized projects have similar shapes, mold sharing with the manufacturer can be negotiated (for a small mold usage fee) to avoid repeated customization. Qinglong has established a mold sharing platform with more than 50 standard molds available for small and medium-sized projects to share. Mold leasing: short-term or small-batch projects can choose mold leasing (daily rent of 1%-2% of mold cost) instead of purchase. Qinglong provided mold leasing services for a temporary exhibition project, reducing mold costs by 60%.

III. Mold Material Selection: Prioritize Cost-Effectiveness, Adapted to Small-Batch Production

GRP molds instead of steel molds: for small-batch production (≤30 pieces), use GRP molds (costing 30%-50% of steel molds) with a service life of ≥15 uses. Qinglong selected GRP molds for 20 custom components of a small and medium-sized project, reducing costs by 45% compared with steel molds. Polyurethane molds instead of high-precision steel molds: for small-batch projects with complex shapes, use polyurethane molds (short machining cycles, moderate cost) with precision up to ±0.5mm, meeting the needs of small and medium-sized projects. Qinglong selected polyurethane molds for 5 irregular components of an art landscape project, reducing costs by 50% compared with high-precision steel molds. Simplify mold structure: molds for non-load-bearing components can adopt simplified reinforcement rib designs (spacing increased from 300mm to 500mm) to reduce material usage. Qinglong simplified the structure of a decorative line mold, reducing costs by 20%.

IV. Cooperation Model Optimization: Collaborate with Manufacturers to Reduce Overall Costs

Consolidated ordering: multiple small and medium-sized projects place joint orders (combined area ≥1000㎡), and batch production reduces the amortized mold cost. Qinglong supports joint procurement for small and medium-sized projects; consolidated orders reduce mold costs by 15%-20%. Extended delivery cycles: give manufacturers sufficient time for mold making and production (≥30 days) to avoid rush fees (typically 20%-30% of mold cost). Qinglong offers mold cost discounts for orders with standard lead times. Choosing from the manufacturer's existing mold library: prioritize shapes from the manufacturer's existing mold library (e.g., standard lines, common curves) for direct production without custom molds. Qinglong currently has more than 100 standard molds that small and medium-sized projects can select directly, with zero mold cost.

The key for small and medium-sized projects to reduce mold costs for custom UHPC components lies in sharing mold expenses through design optimization, mold reuse, material selection and cooperation model innovation. With flexible mold solutions and extensive industry experience, Qinglong Group helps small and medium-sized projects control costs while ensuring quality, enabling the widespread application of UHPC materials in small and medium-sized projects.
