Raw Material Inspection

Inspection Process:
- Material Verification: All plastics and silicones are checked for composition, safety, and compliance with regulatory standards.
- Physical Testing: Strength, flexibility, and temperature resistance are assessed to ensure material integrity.
- Supplier Quality Control: Only verified and reliable suppliers provide raw materials, ensuring consistent quality in mass production.
By maintaining rigorous material selection standards, VOSGES guarantees high-performance and long-lasting products for B2B clients.

In-Production Inspection
Before mass production, VOSGES conducts pre-production sample inspections to confirm design accuracy and manufacturing feasibility.
Key Checks Include:
- Dimensional Accuracy: Ensuring all molds, sizes, and tolerances meet specifications.
- Functional Testing: Assessing locking mechanisms, hinges, and structural integrity.
- Surface & Finishing Review: Evaluating texture, color uniformity, and branding placement.
- Material Performance: Testing for heat resistance, chemical stability, and overall durability.
This process minimizes potential defects and ensures smooth bulk production, reducing risks for clients.

In-Production Inspection
VOSGES implements a real-time quality control system during the manufacturing process, ensuring consistency and defect-free production.
Key Inspection Points:
- Process Monitoring: Automated systems track molding accuracy, assembly precision, and finishing quality.
- Random Sampling: Every batch undergoes randomized checks to detect defects early.
- Structural & Functional Testing: Ensuring snap-fit closures, airtight sealing, and durability.
- Color Consistency: Confirming uniform color matching across all units.
By addressing potential issues during production, we guarantee high-quality output and reduce waste.
Final Product Inspection for Bulk Orders
Before shipment, all products undergo a final inspection to ensure they meet client specifications and international quality standards.
Final QC Process:
- Batch Sampling & Testing: Ensuring all products are free from defects before packaging.
- Logo & Branding Accuracy: Confirming proper placement, sharpness, and adherence.
- Mechanical & Stress Testing: Assessing durability, hinge functionality, and impact resistance.
- Packaging & Labeling Check: Verifying correct barcodes, labels, and customized packaging.
This rigorous inspection process ensures that every bulk order meets quality expectations, delivering consistent and reliable products to B2B partners.
