Stage 1: Rigorous Raw Material Inspection

How do you ensure stone quality from the very beginning? It all starts with the raw materials. The final product can only be as good as its components.

Purity and Particle Size Analysis

Before any material enters our production line, it undergoes strict inspection. We analyze the purity of the quartz sand and the particle size distribution. This ensures the final slab will have superior strength and a uniform appearance.

Color Consistency Checks for Pigments

We source high-quality pigments to create our diverse color palette. Each batch of pigment is checked for color consistency. This guarantees that a slab produced today will match one produced months from now.

Resin Quality and Performance Testing

The resin is a critical component in a quartz slab. We test its performance for bonding strength, clarity, and UV resistance. This ensures the long-term durability and color stability of our products.

Stage 2: In-Process Monitoring During the Manufacturing Process

A great final product requires a flawless manufacturing process. We employ real-time monitoring at every critical stage.

Automated Control of Pressing and Curing

Our factory utilizes automated systems to control the vibrocompression and curing processes. We precisely manage pressure, temperature, and time. This ensures every slab achieves optimal density and hardness.

Real-Time Monitoring of Slab Density

Throughout the pressing stage, we monitor slab density in real-time. This prevents inconsistencies and ensures a uniformly solid and non-porous product. It is a key part of what makes us a reliable supplier.

Checks During Polishing and Finishing

During the polishing and finishing stages, our team conducts checks. They ensure the machinery is calibrated correctly. This guarantees a consistent gloss level and smooth surface on every stone product.

Stage 3: Comprehensive Final Product Inspection

What are stone manufacturing standards? At Kangsheng, our final quality inspection is the most rigorous phase. No product earns our name until it passes every test.

Dimensional Accuracy and Thickness Calibration

We use digital calipers and sensors to check all dimensions. Every slab must meet our strict tolerances for length, width, and thickness. This guarantees easy and precise installation for our clients.

Surface Flatness and Gloss Level Measurement

Our technicians use specialized tools to measure surface flatness and gloss levels. This ensures there are no low spots or inconsistencies in the finish. The result is a perfectly smooth and reflective surface.

Color and Pattern Matching Against Master Samples

Each finished slab is compared against the approved master sample. This visual inspection ensures that the color, veining, and overall aesthetic match the client's expectations perfectly.

Inspection for Surface Defects

Finally, every square inch of the slab is inspected under bright light for any surface defects. This includes pinholes, blemishes, or scratches. Only flawless slabs pass this final stage of our stone quality control.

Stage 4: Secure, Export-Grade Packaging and Loading Supervision

Our commitment to quality extends beyond the factory floor. We ensure your product arrives safely, no matter the destination.

Sturdy, Custom Wooden Crating

We use strong, heat-treated wooden crates for packaging. These are custom-built to securely hold the slabs and prevent movement during transit.

Protective Film and Corner Guards

Each slab is covered with a protective film to prevent surface scratches. We also add corner guards to protect the most vulnerable parts of the stone.

Supervised Container Loading to Prevent Damage

Our team supervises the loading of every container. We ensure crates are loaded correctly and secured properly. This minimizes the risk of damage during shipping. We take pride in being a dependable global stone supplier.
