Ultra-High Pressure Waterjet Cutting System
Mosaic and inlay work is judged on the joint: the more precise the cut and the cleaner the edge, the more the assembly reads as one surface. Hengsheng runs the Flow International ultra-high pressure waterjet from the United States, cutting cold at 60,000 PSI with abrasive, so there is no thermal stress, edges come away clean, and parts go straight to assembly without secondary grinding.
Core Strengths
- Cold cutting at ultra-high pressure: 60,000 PSI water with garnet abrasive cuts without heat, so stone is not left with thermal stress cracking or discolouration.
- Complex outlines in one pass: CNC-controlled paths cut curves, sharp corners and openwork patterns directly, with no re-fixturing.
- Clean edges, no re-grinding: cut edges are neat and square, moving straight into mosaic and inlay assembly and shortening the process chain.
- Multi-material capability: beyond marble and granite, glass, ceramic and metal inlays can be cut, allowing different materials to be combined in one panel.
Key Figures
Service Process
- Pattern design: the mosaic pattern drawn and divided into cuttable units.
- Nesting: units laid out on the slab to raise yield, with kerf width reserved.
- Programming: cut path, speed and abrasive flow set, then simulated.
- Waterjet cutting: units cut to program with continuous water and abrasive supply.
- Trial assembly: cut pieces numbered and dry-laid to confirm joint width and pattern alignment.
Applications
- Artistic floor mosaics in hotel lobbies and clubhouses
- Inlay patterns and line borders on feature walls and entrances
- Shaped outlines, lettering and openwork elements
- Composite decorative panels combining stone with metal and glass
Sustainability & Certification
Waterjet water is settled, filtered and recycled into the 95% plant loop; spent abrasive and slurry are collected and converted into aggregate and filler.
Cold cutting removes secondary grinding, saving abrasive and power; nesting raises yield and offcuts return to mosaic production, taking utilisation past 85%.
Deep Selection Guide
Mosaic succeeds or fails at the joint: width must be uniform, pattern aligned, and colour variation between materials controlled. The waterjet cuts precise outlines, but assembly matters just as much. Confirm joint width and pattern proportion on a small sample before scaling to full size, and agree thickness differences and bonding methods where materials are combined. Have panels dry-assembled and numbered in the factory with a layout drawing supplied, so site laying follows the numbering and adjustment time and waste fall sharply.
- Selection criteria：Taking Artistic floor mosaics in hotel lobbies and clubhouses as the starting point, settle the stone type and thickness first, then check texture and colour against Cold cutting at ultra-high pressure: 60,000 PSI water with garnet abrasive cuts without heat, so stone is not left with thermal stress cracking or discolouration..
- Specification & thickness：Dimension and thickness follow Operating pressure (60,000 PSI), with notes added for the particular conditions of Inlay patterns and line borders on feature walls and entrances to avoid improvised cutting on site.
- Acceptance & records：Verify Complex outlines in one pass: CNC-controlled paths cut curves, sharp corners and openwork patterns directly, with no re-fixturing. item by item and keep the record, accepting on site by number; the batch code traces back to data from both production and testing.
- Sustainability：Waterjet water is settled, filtered and recycled into the 95% plant loop; spent abrasive and slurry are collected and converted into aggregate and filler. Add it to the acceptance documents and tie it to the green building rating requirements in force locally.

FAQ
- How does waterjet differ from laser or saw cutting?
- The waterjet cuts cold with ultra-high pressure water and abrasive, leaving no heat-affected zone, so stone neither discolours nor develops thermal stress cracks. It also cuts glass, ceramic and metal, which suits mosaic and inlay work.
- What is the minimum joint width for mosaic?
- It depends on slab thickness and pattern complexity; in routine work it can be held at around 1mm with consistent width. The figure is confirmed by sample cutting, and panels are dry-assembled and numbered with a layout drawing before dispatch.
