Competitive Advantages: Quality Management
Strict Quality Control, Consistent Reliability

Quality management is integrated into every stage of our manufacturing process. For more than 10 years, our quality management system has been certified to ISO 9001 by BSI. From raw material and component management to process control, assembly, and final inspection, our operations follow standardized procedures and defined quality criteria to maintain consistent and reliable product quality.
Throughout production, key product characteristics—including critical dimensions, appearance, assembly conditions, and other quality requirements—are inspected and controlled according to established standards. In-process quality checks help identify potential issues at an early stage, while quality findings are reviewed and addressed through analysis and continuous improvement of our manufacturing and quality management processes.
Every finished product undergoes 100% inspection before shipment, with inspection items determined according to product characteristics and applicable quality requirements. For fluid control products, reliable sealing performance, structural integrity, and consistent operation are essential. We therefore maintain quality controls throughout the manufacturing process to ensure that finished products meet our established requirements before delivery.
Beyond product inspection, we emphasize the continuous improvement of our overall quality management system. Through ISO 9001 practices, internal quality management, and ongoing process improvement, quality requirements are incorporated into our daily operations. From product development and manufacturing to final inspection and shipment, we are committed to providing consistent, reliable plastic fluid control products designed to meet practical application requirements, building long-term confidence in D.P.S. & DELPHA quality.
Approvals / Certifications: ISO 9001:2015Quality Management System
Standardized Management for Consistent Quality

DELPHA has implemented the ISO 9001 Quality Management System across key operations, including product development, manufacturing, quality inspection, and delivery. Through standardized procedures and systematic management, each process is carried out with clear requirements to maintain consistent product and service quality.
Throughout manufacturing and quality control, established standards are applied to process control, product inspection, and documentation. Continuous monitoring and improvement help reduce process variation and ensure that products meet specifications and customer requirements.
For DELPHA, ISO 9001 is more than an international certification—it is the foundation of our daily quality management. Through continuous improvement and accumulated experience, we are committed to maintaining a consistent, traceable, and continuously evolving quality system.
