Intelligent Quality Control System
Quality watched by people alone always lets something through; only a system survives staff changes. Hengsheng runs an intelligent quality control system with more than 40 inspection gates covering compressive strength, water absorption, abrasion resistance and slip resistance. Machine vision and manual re-checking form a double gate, every batch carries its own test report, and image archiving delivers full-chain traceability at a factory pass rate of at least 99.7%.
Core Strengths
- Gates across the whole process: more than 40 inspection nodes run from inbound to dispatch, measuring compressive strength, water absorption, abrasion resistance and slip resistance item by item.
- Optical and manual double gate: machine vision scans for cracks, voids, colour deviation and broken veining, grading and marking automatically, before inspectors re-check — the two gates validate each other.
- Image archive and traceability: scan images and test data are filed against batch codes, traceable from finished code back to quarry, block batch and machining station.
- Measurable pass rate: the system tracks factory pass rate, held above 99.7% over the long term, with failures removed before final inspection and never entering delivery.
Key Figures
Service Process
- Inbound testing: absorption, compressive strength and appearance sampled to establish the batch baseline.
- In-process gates: each stage inspected before the next, with images and data recorded.
- Optical scanning: machine vision scans the face, identifying and grading defects automatically.
- Manual re-check: inspectors verify flagged results against the standard, releasing or returning for repair.
- Final inspection: batch data compiled into a test report supplied and archived with the goods.
Applications
- Public works and tender projects requiring complete quality documentation
- Standardised hotel group procurement needing batch-level traceability
- Acceptance situations where appearance is disputed and image records are needed
- Property managers requiring quality files for long-term maintenance
Sustainability & Certification
Strict inbound and in-process inspection reduces scrap and rework, cutting secondary consumption of material and energy, alongside 95% process water recycling and over 85% waste utilisation.
Each batch's test data also feeds environmental indicator statistics, sharing one process record with the ISO 9001 and ISO 14001 systems.
Deep Selection Guide
To confirm a quality system genuinely operates, ask for three things: a batch test report, the scan images for that batch, and the non-conforming product disposition record. With all three, the system is real. Agree the sampling standard and acceptance method in the contract and require reports with delivery; match report to physical code by batch on receipt. Where appearance requirements are strict, also agree how colour grading is judged and how reference samples are sealed, so acceptance does not become two opposing opinions.
- Selection criteria：Start from the actual conditions at Public works and tender projects requiring complete quality documentation, then narrow the options by Gates across the whole process; colour is the last layer to consider.
- Specification & thickness：Set panel size and thickness first by Control points (40+), then thicken or reduce locally for Standardised hotel group procurement needing batch-level traceability, with cut-out positions noted on the same drawing.
- Acceptance & records：Make Optical and manual double gate: machine vision scans for cracks, voids, colour deviation and broken veining, grading and marking automatically, before inspectors re-check — the two gates validate each other. the focus of acceptance, checked and archived before dispatch; accept on site by number, with any dispute traceable to that batch.
- Sustainability：Strict inbound and in-process inspection reduces scrap and rework, cutting secondary consumption of material and energy, alongside 95% process water recycling and over 85% waste utilisation. Write it into the acceptance terms and apply the local green building requirements alongside it.
What Hengsheng does with Intelligent Quality Control System is join quarry-direct supply, smart manufacturing and global delivery into a single line where every step is documented, so project teams need not rely on judgement alone to weigh risk.
FAQ
- How do intelligent inspection and manual checking relate?
- They validate each other: machine vision scans the full slab face, identifying cracks, voids, colour deviation and broken veining consistently; inspectors re-check for final judgement and borderline cases, avoiding the misjudgement that comes from relying on the algorithm alone.
- Can we have the records for our batch?
- Yes. Every batch carries its own test report and image archive, retrievable by batch code, covering inbound testing, in-process gate records and final inspection data, and traceable back to quarry and block batch.
