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

The beauty of architectural texture stems from the ingenious combination of materials and craftsmanship. In the application of new decorative materials such as UHPC (Ultra-High Performance Concrete), mold technology is the core link in achieving surface texture effects of formed elements. As an industry player with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong has always believed that molds are not only forming tools, but also key vehicles for conveying design language and giving buildings their soul.

Mold design is the wellspring for achieving texture effects. The high fluidity and high strength of UHPC place stringent demands on mold precision and surface treatment. During the detailed design stage, the appropriate mold material must be selected according to project requirements—steel molds suit high-precision repetitive production, silicone molds excel at capturing complex texture details, while wooden molds offer greater flexibility for irregular curved shapes. Taking the light-transmitting concrete project of the Nanjing Road Century Plaza renovation as an example, Qinglong used parametric design and CNC machining to engrave texture patterns with 0.1mm precision onto the mold surface, ultimately achieving the "flowing light and shadow" artistic effect of the UHPC panels.

Process control is the "quality gate" for rendering texture effects. The vibration process of UHPC directly affects texture clarity, vacuum casting technology reduces bubble damage to texture integrity, while the curing regime determines the release performance between material and mold. The standardized production line established by Qinglong at its production base in Nanning, Guangxi, through constant temperature and humidity curing chambers and a fully automatic demolding system, ensures that the texture fidelity of every square meter of UHPC components reaches over 98%. This full-chain quality control capability is precisely the ultimate pursuit of process details by a national high-tech enterprise.

Innovative technology opens up "infinite possibilities" for texture effects. With the application of technologies such as 3D-printed molds and modular combination molds, the texture expression of UHPC has broken through traditional limitations. The industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)", which Qinglong participated in formulating, specifically sets norms for mold texture precision, driving the industry to leap from "imitating nature" to "creating texture". In the Dongguan Women and Children's Activity Center project, by cross-integrating GRC and UHPC mold technologies, the perfect unification of sandstone-imitating texture and irregular curved surfaces was successfully achieved.

From the artistic reliefs of grand theaters to the curtain wall textures of commercial complexes, every detail of UHPC surface texture is a deep dialogue between material properties and mold craftsmanship. Qinglong's 28 years of industry experience is reflected not only in the accumulation of 58 patented technologies, but also in its full-chain service capability of transforming artistic inspiration into engineering reality. In the future, with the deep integration of BIM technology and intelligent molds, UHPC materials will surely bring more texture solutions combining "form and spirit" to architectural decoration, making every building a unique aesthetic carrier.
