Quality is designed into our products from the earliest stages. Our design and development process integrates quality considerations at every step:
– Design review procedures that evaluate manufacturability, compliance, and performance requirements.
– Prototyping and validation testing to confirm designs meet functional and aesthetic specifications.
– Design for manufacturing (DFM) principles that reduce complexity and variation.
– Material selection guided by compatibility, safety, and regulatory requirements.
– Design control documentation ensuring traceability from customer requirements through final specifications.
Effective quality management depends on seamless communication and information flow across all functions. Our information transmission system ensures:
– Real-time data capture and reporting from production lines to quality teams.
– Standardized documentation formats for inspection records, test results, and non-conformance reports.
– Digital quality management tools that centralize data and enable rapid access and analysis.
– Clear escalation procedures for quality alerts and deviations requiring immediate attention.
– Customer communication protocols for timely updates on quality status, certifications, and compliance documentation.
Testing Standards & Methodologies
Our testing methods are aligned with international standards and industry best practices to ensure repeatable and reliable results. Dedicated inspection and testing teams work with calibrated equipment and documented methods, backed by certifications including ROHS, TUV, ISO, REACH and BSCI to meet global regulatory requirements.
Physical Performance Tests
Impact resistance, stress and load tests, drop tests, leak tests, and pressure tests where required to validate structural integrity and functional reliability under real-world handling and transportation conditions.
Dimensional Measurement
Critical dimensions, wall thickness uniformity, neck finish profiles, and thread specifications to ensure compatibility with equipment. Precise measurement using calipers, micrometers and optical comparators validates that molded parts meet tight tolerances throughout production runs.
Visual Inspection Protocols
Inspect the surface finish, color consistency, print clarity, decoration alignment, and check for defects such as cracks, warping, scratches, bubbles, or contamination. Use standardized lighting equipment and reference samples to ensure consistency in judgment across different shifts and production batches.
Adhesion & Durability Testing
• 3M tape test is pressed firmly onto the decorated surface and rapidly pulled away. The test passes if no coating or ink lifts off.
• Rubbing resistance test: A cloth is rubbed repeatedly across the printed surface to simulate handling. The decoration must remain intact without fading or transfer.
• Cross-hatch adhesion test: A grid is cut through the coating, tape is applied and removed. Less coating removal indicates better adhesion.
• Boiling water resistance test: Decorated packaging is submerged in boiling water to test heat and moisture durability. Coatings must not blister or peel.
Functional Performance Validation
Critical dimensions, wall thickness uniformity, neck finish profiles, and thread specifications to ensure compatibility with equipment. Precise measurement using calipers, micrometers and optical comparators validates that molded parts meet tight tolerances throughout production runs.
Chemical & Compatibility Checks
Through basic screening tests, the system systematically verifies the compatibility and safety of cosmetic formulations with packaging materials. This includes leak testing using simulated liquids and a comprehensive assessment of material stability and compatibility.
