How the DLC Stamp Reflects Donloucos Quality Standards.
The DLC stamp is a symbol of Donlouco’s commitment to quality, traceability, and customer assurance at every stage of the manufacturing process for hydraulic cylinder parts.
1. Certified Quality Management
Donlouco operates under ISO 9001 and EN 1090 certifications, which are internationally recognised standards for quality assurance and structural steel CE marking. These certifications require strict controls over every step of the production process, from material sourcing to final inspection, ensuring that all components meet or exceed customer and regulatory requirements.
2. Comprehensive Quality Control
Every part with the DLC stamp has undergone thorough quality checks, including:
Dimensional and tolerance verification
Surface finish and shape assessment
Material certification and chemical analysis
Non-destructive testing for cracks or imperfections (e.g., dye penetrant, magnetic particle, ultrasonic testing)
Tensile and impact testing as required.
3. Full Traceability and Documentation
The DLC stamp ensures that each part is fully traceable, with supporting documentation, including material certificates, dimensional reports, and inspection records, provided with every shipment. This traceability is essential for compliance with ISO 9001, EN 1090, and customer-specific standards.
4. On-Site and Independent Verification
Donlouco’s quality assurance includes both in-house inspections and independent laboratory testing, ensuring that parts not only meet internal standards but are also validated by third-party experts. This dual-layer verification reinforces reliability and customer confidence.
5. Local Accountability, Global Reach
The DLC stamp also reflects Donlouco’s unique approach: having qualified engineers and quality managers on the ground with our own office in China, combined with Irish-based project management, planning, scheduling, etc. This ensures consistent quality, timely issue resolution, and seamless communication for customers in Ireland and Europe.
Consistent, Reliable Quality.
In summary:
The DLC stamp is more than a mark - it’s a guarantee that every component has passed Donlouco’s stringent quality controls, is fully certified and traceable, and is backed by both local accountability and global expertise.
