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

In the field of contemporary architectural decoration, UHPC (Ultra-High Performance Concrete), with its outstanding mechanical properties and exceptional formative expressiveness, has become the core material for shaping the artistic quality of building skins. The texture effects on UHPC molded surfaces, as a key carrier for conveying design concepts, depend heavily on innovation in mold technology and refinement of process methods. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze, from three dimensions—mold design, material compatibility, and process control—how mold technology endows UHPC surfaces with a rich texture language.

As the “genetic carrier” of UHPC textures, the design precision of molds directly determines the presentation of the final effect. In the detailed design stage, the mold substrate must be selected according to project requirements: for high-precision textures (such as stone-imitating lychee finish and water ripples), steel molds are usually adopted, using CNC engraving technology to achieve 0.1mm-level control of texture depth; for complex curved-surface textures or mass production needs, GRP (fibreglass reinforced plastic) molds are the preferred choice thanks to their light weight and ease of replication—through 3D scanning and mold-replication processes, handcrafted textures or parametric design textures can be accurately reproduced. In the renovation project of Century Plaza on Nanjing East Road, Qinglong Group, through the synergy of custom GRP molds and UHPC materials, successfully achieved industrialized production of gradient textures on light-transmitting concrete surfaces, and the project won the Silver Award of the First UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup).

The compatibility between UHPC material properties and mold processes is the core guarantee for the stable presentation of texture effects. Mold surface treatment processes must precisely match the flowability and initial setting time of UHPC: mirror-polished molds yield the native fine texture of UHPC, while sandblasted or chemically etched mold surfaces can create rugged textural effects. In the production stage, Qinglong Group uses its self-developed “dynamic mix proportion pouring technology” to adjust the water-cement ratio and fiber content of UHPC according to different texture requirements—for example, in the production of wood-grain-imitating UHPC components, by optimizing material flowability, the concrete can fully fill the wood-grain grooves of the mold, and combined with steam curing, the clarity and strength of texture details are ensured. This material-mold synergy technology has been widely applied in the exterior walls of commercial complexes and landscape projects undertaken by Qinglong.

A full-process quality control system is the key to ensuring the consistency of UHPC texture effects. From 3D scanning inspection at the mold acceptance stage (ensuring texture deviation ≤0.5mm), to pouring pressure monitoring during production (controlled at 0.3-0.5MPa to avoid texture deformation), to laser texture comparison after demolding, Qinglong Group has established full-chain quality control standards covering detailed design, manufacturing, and construction installation. Especially in large-scale projects, parametric linking of molds and components through BIM technology can effectively resolve texture differences between batches. As a participating drafting unit of the industry standard “General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components”, Qinglong Group has transformed 28 years of process experience into standardized procedures, providing technical support for the stable realization of UHPC texture effects.

Innovation in mold technology is redefining the aesthetic boundaries of UHPC materials. From traditional stone- and wood-imitating textures to the parametric textures and light-transmitting textures required by modern architecture, advances in mold technology have elevated UHPC from a structural material to a “carvable artistic carrier”. With the mission of “creating beautiful architecture”, Qinglong Group, by integrating its full-chain advantages in detailed design, mold R&D, and manufacturing, provides designers with one-stop solutions from concept to realization. Whether it is the curved curtain wall textures of grand theaters or the customized skins of commercial landmark buildings, Qinglong has always driven the aesthetic expression of UHPC materials through technological innovation, helping to create architectural works that combine structural performance with artistic value.
