International-Standard Precision Fabrication
The same block becomes different grades of product on different lines. Hengsheng has built an international dust-free intelligent production base, importing top-tier European automated equipment from Italy and Germany — five-axis CNC centres, automatic polishing lines, precision carving machines and complex forming equipment — all under computer numerical control, with 68 quality gates and image archiving so the dimensions, tolerances, gloss and edge detail of every batch can be traced and verified.
Core Strengths
- Dust-free intelligent base: an international-scale dust-free plant where polishing and resin treatment run in controlled conditions, limiting the effect of airborne particles on polished faces and resin layers.
- Top-tier European equipment: automated Italian and German machinery including five-axis CNC centres, automatic polishing lines, precision carvers and complex forming equipment, all CNC-operated.
- Full-process visibility: in-house production scheduling and quality traceability systems give end-to-end visibility from block opening to finished dispatch within one enclosed operation.
- Micron-level standard: 68 quality gates with image archiving track dimensions, tolerances, gloss and edge detail, preserving the natural veining and lustre of the stone.
Key Figures
Service Process
- Block opening: cut to layout numbering with thickness held within ±0.5mm.
- Calibration and polishing: completed in clean rooms, with gloss regulated by servo loop.
- Forming: five-axis CNC and waterjet handle complex work, mosaic and carving at ±0.05mm.
- Protection and final inspection: six-face nano coating, then all 68 gates.
- Packing and dispatch: codes reconciled with packing lists before loading, with images and data archived by batch.
Applications
- Hotel projects with strict tolerances and gloss consistency
- Precision fabrication of complex elements and artistic mosaic
- Public projects requiring full traceability and image records
- Concentrated production and supply of large cut-to-size volumes
Sustainability & Certification
Clean rooms carry dust extraction and wastewater settling loops within the 95% plant water recycling system; offcuts and slurry are sorted for reuse at over 85% utilisation.
Equipment runs on variable-frequency drives and efficient lighting, with rooftop solar covering over 80% of plant demand and a 30% annual carbon reduction target.
Deep Selection Guide
Judge a fabrication system on three things: whether equipment is fully automated CNC, whether the environment is controlled and dust-free, and whether inspection records are traceable. With all three, consistency is assured. Write tolerances, gloss and finish requirements into the contract and seal physical samples; ask for first-article inspection records before volume production. For complex or mosaic elements, also confirm factory dry-assembly numbering and assembly drawings to cut site adjustment time.
- Selection criteria：When deciding what stone Hotel projects with strict tolerances and gloss consistency needs, Dust-free intelligent base is the decisive factor; once that is settled the rest of the selection has a baseline.
- Specification & thickness：Control dimension by Five-axis forming tolerance (±0.05mm) and set the thickness allowance by Precision fabrication of complex elements and artistic mosaic; junctions and corners should be marked on the drawing before work starts.
- Acceptance & records：Acceptance centres on Top-tier European equipment: automated Italian and German machinery including five-axis CNC centres, automatic polishing lines, precision carvers and complex forming equipment, all CNC-operated.: checked before dispatch, re-checked on site, and filed by batch so the record can be retrieved later.
- Sustainability：Clean rooms carry dust extraction and wastewater settling loops within the 95% plant water recycling system; offcuts and slurry are sorted for reuse at over 85% utilisation. This must appear in the acceptance documents and be aligned with local environmental and green material rules.
The Hengsheng advantage on International-Standard Precision Fabrication is quality control pushed forward into selection and fabrication, closed out with complete test and delivery records the project team can rely on.
FAQ
- What does full-process visibility actually show?
- Through the scheduling and traceability system you can see which operation a batch is in, its inspection records and slab scan images. The finished code traces back to quarry, block batch and machining station, with dimensions, tolerances, gloss and edge detail all recorded.
- What practical difference does a clean room make?
- Polishing and resin treatment in controlled conditions prevent airborne particles scratching polished faces or contaminating resin layers, reducing orange peel, pinholes and inclusions, so gloss is more stable and surfaces cleaner.
