How to Achieve Texture Effects on UHPC Shaped Surfaces Through Molds: Key Technologies and Process Methods Explained

When architectural facades become an artistic language, the textural expressiveness of UHPC is redefining the boundaries of spatial aesthetics. As an industry player with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong has always believed that mould technology is the key to unlocking the sculptural charm of ultra-high performance concrete.

In contemporary architectural design, UHPC (Ultra-High Performance Concrete), with its ultra-high strength and exceptional plasticity, has become the material of choice for shaping iconic building facades. From the streamlined curtain walls of grand theatres to the parametric textures of commercial complexes, the textural details on UHPC surfaces directly determine a building's visual quality and artistic expression. Achieving all of this depends on the precision support of mould technology. As a national high-tech enterprise integrating detailed design, manufacturing, construction and installation, Qinglong has accumulated extensive hands-on experience in UHPC mould technology. This article will systematically analyze the mould-based pathways for achieving textural effects.

1. The Technical Core of UHPC Texture Moulds: Full-Chain Control from Design to Materials

The texture precision of UHPC sculptural surfaces depends on the mould's "replication capability", which requires mould design to achieve a triple match: aesthetic alignment with the architectural design intent, physical compatibility with material properties, and efficiency alignment with production processes. When Qinglong undertook the light-transmitting concrete project for the Century Plaza renovation on Nanjing East Road, it addressed the 0.5mm-level texture precision requirement by using 3D scanning technology for reverse modelling, combined with Rhino parametric design software to build a digital mould prototype, ensuring the precise restoration of textural details. The choice of mould material is equally critical — for different texture requirements, Qinglong innovatively adopts multi-material combination solutions such as aluminium alloy moulds (suited to fine textures), GRP moulds (suited to complex curved surfaces), and silicone moulds (suited to ultra-fine reliefs). Its self-developed modified silicone moulds can be reused more than 300 times, a lifespan 40% longer than traditional materials.

2. Four Key Processes for Texture Realization: The Technical Accumulation of Qinglong's 28 Years of Experience

In the mould manufacturing stage, Qinglong has summarized four core process systems: "carving, casting, pressing, and spraying". For the textures of European classical-style architectural decorative lines (such as Roman columns and cornices), CNC engraving technology is used to machine wooden master moulds, combined with vacuum casting processes to form high-precision GRP moulds capable of accurately presenting 0.1mm pattern details. For stone-imitation textures on commercial building exterior walls, Qinglong innovatively developed a hydraulic embossing process, applying 8-12MPa pressure through custom steel moulds during the initial setting stage of UHPC so that aggregate distribution closely matches the grain of natural stone. For the openwork light-transmitting textures commonly used in museums and art galleries, photosensitive resin 3D-printed moulds are employed to achieve complex topological structures that traditional processes struggle to complete. Notably, Qinglong established a mould temperature control system at its production base in Nanning, Guangxi, effectively solving shrinkage and deformation problems during texture forming through constant-temperature curing at ±2°C.

3. Full-Chain Service Assurance: A Quality Closed Loop from Detailed Design to After-Sales Maintenance

As a manufacturer of customized UHPC/GRC/GRG/GRP products, Qinglong knows well that achieving textural effects is not an isolated production step but a systematic project spanning design, production, and installation. During the detailed design stage, the technical team conducts feasibility analysis on the texture schemes provided by designers, using BIM technology to simulate the forming effects of different mould processes. In production, an RFID chip traceability system records the mould parameters and curing data of each component. During on-site installation, 3D laser scanning positioning ensures that texture jointing errors are controlled within 2mm. This full-chain service capability enabled Qinglong to successfully achieve texture continuity between double-curved UHPC curtain walls and GRC decorative lines in projects such as the Dongguan Women and Children's Activity Center, winning the AALBORG WHITE Cup GRC Construction Engineering Innovation Award.

From breakthroughs in materials science to innovations in process systems, the development of UHPC texture mould technology is driving architectural facades toward greater expressiveness. As a national "specialized, refined, distinctive, and innovative" enterprise, Qinglong remains committed to its mission of "creating aesthetically beautiful architecture" and will continue to explore the deep integration of mould technology and digital design. For designers and owners pursuing breakthroughs in architectural aesthetics, choosing a UHPC manufacturer with full-chain service capability is not only an assurance of textural effects but also a long-term investment in the artistic value of architecture. In the future, as technologies such as 3D printing and intelligent moulds mature, UHPC materials will surely showcase their unique textural charm in more landmark buildings.
