How Are Texture Effects on UHPC Shaped Surfaces Achieved Through Molds? Precise Replication and Durability Assurance

The texture effect of UHPC shaped surfaces is achieved through "mold material selection + texture replication process + surface treatment optimization", enabling precise reproduction of diverse textures such as faux stone, faux wood, and carved patterns. With 3D scanning and five-axis engraving technology, Qinglong achieves a texture reproduction rate of over 95%. Projects such as Shanghai New World Plaza and Dongting Lake Museum feature textures that remain lasting and vibrant.

I. Mold Material Selection: Adapting to Different Texture Requirements

Mold material determines texture reproduction precision. Polyurethane soft molds: suitable for complex textures (carvings, faux wood), with good elasticity and delicate texture replication; Qinglong's polyurethane molds have a surface roughness of Ra≤0.8μm, achieving a 98% reproduction rate for faux wood textures. Steel molds: suitable for regular textures in mass production (fine sand finish, bush-hammered finish), with high strength and long service life; Qinglong's steel molds can be reused more than 500 times, with texture consistency reaching 99%. Silicone molds: suitable for ultra-fine textures (openwork carvings, digital patterns), with strong flexibility; Qinglong's silicone molds can replicate fine patterns as small as 0.1mm. Composite molds: polyurethane + steel frame, balancing complex textures with structural stability; Qinglong uses composite molds for complex shaped textures, balancing reproduction rate and durability.

II. Texture Replication Process: Precisely Reproducing Design Effects

Process steps ensure textures are precisely realized. 3D scanning and data collection: for physical texture samples, laser scanning captures point cloud data with a precision of 0.05mm; after scanning, Qinglong compares the results with the design model, with errors ≤0.2mm. Five-axis engraving: mold textures are engraved according to 3D models, with an engraving precision of ±0.3mm for carved and faux stone textures; Qinglong's five-axis machining equipment can process textures with a minimum curvature radius ≤300mm. Hand finishing: after engraving complex textures, manual polishing eliminates machining marks; Qinglong's hand finishing team each has more than 5 years of experience, improving texture smoothness by 30%. Texture pressing: after UHPC slurry is poured, high-pressure vibration ensures the slurry fully conforms to the mold texture; Qinglong's vibration pressure is ≥0.6MPa, with texture penetration depth ≥2mm for a strong three-dimensional effect.

III. Surface Treatment Optimization and Project Practice

Post-treatment and verification enhance texture durability. Demolding post-treatment: light polishing removes burrs while preserving texture integrity; Qinglong's polished surface roughness is Ra=1.6-3.2μm, providing a delicate feel. Protective coatings: fluorocarbon varnish or silane impregnation is applied to protect textures from fading and chalking; Qinglong's protective layer withstands 1000 hours of UV aging without damage to textures. Testing and verification: texture reproduction testing (≥95%) and abrasion testing (wear resistance ≥Grade 4); Qinglong's testing pass rate is 100%. Project cases: the UHPC faux wood translucent panels at Shanghai New World Plaza, produced with polyurethane molds + five-axis engraving, achieved a 98% wood grain reproduction rate, paired with light guide rods for artistic translucency; the faux stone UHPC components at Dongting Lake Museum, produced with steel molds + 3D scanning replication, achieved a 95% stone texture reproduction rate with no fading after 8 years of use. Qinglong's advantages: any texture can be customized, texture samples are provided for confirmation, ensuring the final effect matches the design.
