Quality Control for Wooden Components
Lower defects, stable batches, consistent appearance & feel. Our comprehensive QC system ensures your wooden components meet the highest standards from incoming materials to final delivery.
Quality Promise
Five key areas where we ensure excellence in every wooden component
Grain & Color Consistency
Standardized wood selection and color matching across batches. Visual standards maintained through approved sample references.
Surface Finishing Excellence
Controlled gloss levels, smooth tactile feel, and defect-free coatings. Every surface meets luxury standards for touch and appearance.
Critical Dimensions
Precise measurement control for fit and assembly. All dimensions verified against customer specifications with documented tolerances.
Fit & Assembly
Functional testing ensures perfect assembly with mating parts. Stability, grip comfort, and operational smoothness verified.
Packaging Protection
Anti-scratch packaging systems prevent damage during transit. Components arrive in pristine condition, ready for your production line.
End-to-End QC Flow
Five critical checkpoints ensure consistent quality from raw materials to final delivery
Incoming Inspection
Wood moisture content verification (8-12%), visual defect screening for knots and cracks, grain direction assessment, and batch identification labeling. Each lot receives a unique tracking number for full traceability.
First-Article Approval
Complete dimensional verification against customer drawings, surface finish confirmation to approved samples, and functional fit testing with mating components. Customer approval required before production continues.
In-Process Inspection
Hourly patrol inspections and statistical sampling of critical dimensions, hole positioning accuracy, assembly fit verification, and visual appearance consistency. Real-time process adjustments maintain quality standards.
Surface Finishing QC
Gloss measurement with standardized meters, color difference evaluation against master samples, tactile feel assessment, and coating defect inspection for runs, orange peel, and pinholes. Each batch documented with photographic records.
Final Inspection & Packing
100% final inspection for dimensional accuracy, surface quality, and functional performance. Anti-scratch protective packaging with foam inserts and moisture barriers prevents damage during shipping.

Defect Prevention
Proactive measures to eliminate rework and customer complaints before they occur
Standardized Sample References
Golden samples and limit samples establish clear visual standards for color, grain, and surface quality. Production teams reference approved samples to maintain consistency across all batches.
Critical Point Confirmation
Key process checkpoints require supervisor approval before proceeding. This includes material selection, first-piece approval, finish application, and final packaging to prevent downstream issues.
Change Management Protocol
Any process, material, or specification changes require formal approval and documentation. New samples are produced and approved before implementing changes to maintain quality consistency.
Batch Color & Feel Matching
Each production batch is matched against previous batches for color consistency and tactile feel. Digital color measurement and physical comparison ensure seamless batch-to-batch continuity.
Frequently Asked Questions
Everything you need to know about our quality control process
How do you control batch-to-batch consistency?
We maintain batch consistency through standardized wood selection criteria, approved color master samples, and digital color measurement (ΔE ≤ 2.0). Each new batch is physically compared against previous production samples before approval. Our batch tracking system ensures complete traceability and allows us to match future orders to previous deliveries.
What drawings and standards do you need for quality inspection?
We require technical drawings with dimensional tolerances, surface finish specifications (gloss level, texture), approved color samples or Pantone references, and assembly/fit requirements. If available, provide existing component samples, quality standards documentation, and any specific inspection criteria. Our team can work with basic sketches and develop detailed specifications together.
How do you determine inspection frequency and sample sizes?
Inspection frequency follows AQL (Acceptable Quality Level) standards based on batch size and criticality. Typically: incoming materials 10% sampling, in-process hourly checks on critical dimensions, surface finish 5% sampling, and 100% final inspection. For high-volume production, we use statistical process control with reduced inspection frequency once process capability is proven.
What are the most common surface finish defects and how do you prevent them?
Common defects include runs/sags (prevented by proper spray technique and viscosity control), orange peel texture (controlled by spray pressure and distance), pinholes (eliminated by proper surface preparation and coating temperature), and dust contamination (prevented by controlled spray booth environment). We maintain detailed process parameters and conduct regular equipment calibration.
How do you prevent scratches and damage during packaging and shipping?
Components are individually wrapped in soft tissue paper or foam sleeves, separated by protective dividers in custom-fit cartons. We use anti-static foam for high-gloss finishes and moisture barrier bags for long transit times. Drop testing and vibration testing validate packaging effectiveness. Special handling instructions are provided for fragile or high-value components.
What happens when defects are discovered during inspection?
Defective components are immediately isolated and tagged for investigation. We conduct root cause analysis to identify the source, implement corrective actions to prevent recurrence, and determine if rework is possible or replacement is required. Customers are notified within 24 hours with proposed solutions and revised delivery schedules. All corrective actions are documented for continuous improvement.
Can you provide quality documentation for regulatory compliance?
Yes, we provide comprehensive documentation including First Article Inspection reports, material certificates (FSC, CARB compliance), dimensional inspection data, surface quality reports, and batch traceability records. Documentation is available in multiple formats and can be customized to meet specific regulatory requirements for different markets and industries.
How quickly can you develop a quality control plan for new projects?
We can provide a preliminary QC plan within 24 hours of receiving your specifications and drawings. This includes critical control points, inspection methods, sampling plans, and documentation requirements. The plan is refined during the sample development phase and finalized before production begins. Our experience across multiple industries allows us to quickly identify potential quality risks and prevention strategies.
