At Sanait Co. Ltd, quality isn’t just a promise—it’s embedded in every step of our manufacturing process. With over 15 years of expertise in producing premium acrylic products including display stands, blocks, boxes, trays, and custom fixtures, we maintain a defect rate below 0.4% through our rigorous 4-stage quality control system.
📊 Our Quality Performance
✅< 0.4% Defect Rate
✅100% Products Inspected
✅4 Inspection Stages
✅15+ Years Quality Excellence
Our 4-Stage Quality Control Process
We inspect every single piece—not random samples. From raw material to final shipment, each acrylic product undergoes comprehensive verification to ensure it matches your approved specifications perfectly.
Stage 1: Incoming Material Inspection
Before Production Begins
Quality starts with premium materials. We only source acrylic sheets from SGS-certified suppliers who meet international safety standards.

What We Check:
- ✅ Optical Clarity — Zero bubbles, inclusions, or haze
- ✅ Thickness Accuracy — Verified with digital calipers (tolerance ±0.1mm)
- ✅ Surface Integrity — No scratches, scuffs, or protective film defects
- ✅ Color Consistency — Batch matching for colored acrylic sheets
- ✅ UV Stability — Compliance with SGS technical data sheets
If It Fails:
Sheets that don’t meet our standards are immediately returned to suppliers. We never cut material that fails inspection—preventing waste and ensuring flawless final products.
Stage 2: In-Process Inspection
During Cutting, Forming & Finishing
Real-time monitoring at every production station catches issues before they progress.
What We Check:
- ✅ Cut Dimensions — Verified against production drawings (±0.1mm tolerance)
- ✅ Edge Quality — Diamond polishing inspection for chips, unevenness, or haze
- ✅ Bend Angles — Measured with precision gauges for structural accuracy
- ✅ Print Alignment — Tested against positioning guides before full production runs
- ✅ Assembly Fit — Hardware fitting and bonding stability checks
If It Fails:
Problems are fixed immediately at the source. A miscut panel is recut, not forced through assembly—stopping quality issues before they compound.
Stage 3: Final Product Inspection
After Assembly, Before Packing
Every finished product is compared side-by-side with your approved sample—no exceptions, no “close enough.”
What We Check:
- ✅ Side-by-Side Sample Comparison — Every piece, not spot checks
- ✅ Surface Inspection — Under direct light for scratches, fingerprints, or bonding residue
- ✅ Assembly Integrity — Joint bond strength testing and hardware fit verification
- ✅ Print & Engraving — Alignment, color accuracy, and adhesion strength
- ✅ Final Dimensions — Complete re-measurement against approved specifications
If It Fails:
Any piece that doesn’t match the approved sample is rejected and remade from scratch. This is why our defect rate stays below 0.5%.
Stage 4: Pre-Shipment Inspection
Packed Order, Before Leaving Factory
We verify that products survive packing intact and all documentation is accurate.
What We Check:
- ✅ Random Carton Pulls — Verify product quality survived packaging
- ✅ Packaging Integrity — Protective film, foam inserts, corner protectors properly placed
- ✅ Quantity Confirmation — Cross-checked against purchase order
- ✅ Shipping Documentation — Labels, invoices, and customs paperwork verified
- ✅ Drop-Test Standards — Packaging tested to ensure safe global delivery
If It Fails:
If random inspection reveals any issue, the entire batch is unpacked and re-inspected. No shipment leaves until every carton passes.
