BAO KIEN STONE QUALITY CONTROL
Quality, Controlled at Every Stage.
From incoming materials to final shipment, every Bao Kien Stone product moves through a documented quality control process built around measurable standards, traceable records and timely corrective action.

One Process.
Multiple Control Points.
Quality is not a single inspection at the end of production. It is a continuous control system covering materials, manufacturing, finished products, shipment and corrective action.
01
Incoming Quality Control
Materials are verified against purchase and delivery information before entering production. Model, batch, quantity, documentation, dimensions, appearance and material condition are checked through sampling inspection.
02
First Article Approval
New batches, material changes, mould changes and process adjustments require first article inspection. Mass production begins only after the first piece has been approved.
03
In-Process Quality Control
QC patrol inspections are conducted every one to two hours during mass production, with particular attention to cutting, polishing, forming and bonding processes.
04
Final & Pre-Shipment Inspection
Finished products are checked against order requirements, customer standards, packaging specifications and shipping information before release.
05
Corrective Action
Non-conforming products are identified, isolated and processed through rework, repair, controlled acceptance or disposal. Repeated defects trigger an 8D corrective-action process.
What We Inspect
Every inspection is conducted against applicable drawings, approved samples, order specifications and customer-defined requirements.
Dimensions
Overall dimensions, profiles, curves
and specified tolerances.
Flatness
Surface flatness and dimensional consistency
across the finished product.
Surface Appearance
Scratches, chips, visible damage
and other surface imperfections.
Color Consistency
Color and visual consistency are reviewed
against approved reference samples.
Packaging Protection
Packaging condition, protective materials,
labels and carton marks.
Shipment Quantity
Product quantity and shipping information
are verified before release.
Clear Status. Controlled Decisions.
Non-conforming materials and products are separated by stage and disposition.
Depending on the result of the assessment, they may be reworked, repaired, scrapped or submitted for controlled acceptance.
Measured. Recorded. Traceable.
Inspection results are documented throughout the quality process. Controlled records help our team track material batches, production findings, corrective actions and final shipment status.

Dedicated Quality Responsibilities.
Quality control responsibilities are assigned across incoming inspection, in-process control, pre-shipment inspection, documentation and corrective-action management.
Our quality documentation, inspection tools, approved samples and calibration records are managed through controlled numbering and filing procedures. Internal audits, employee training and regular quality reviews support consistent implementation across the factory.
