Quality Assurance for Every NPI’s Phase
At RPD, quality is embedded in every step of the manufacturing process. We conduct rigorous inspections across all three production phases—pre-production, in-production, and post-production. Full-Line QC: Implement IQC (Incoming Quality Control) , IPQC (In-Process Quality Control) , and OQC (Outgoing Quality Control) to monitor pilot run quality.using advanced equipment such as CMMs (Coordinate Measuring Machines), XRF analyzers, and high-precision measurement tools. With over 20 specialized inspection devices, including two high-accuracy CMMs, our quality control framework ensures that every part meets exact specifications.
Our ISO-certified quality team, supported by more than 10 dedicated quality engineers, brings nearly two decades of expertise in prototyping and manufacturing excellence. We provide detailed inspection reports covering functional performance, regulatory compliance, and dimensional accuracy. This commitment to precision and transparency guarantees that every component we deliver is reliable, traceable, and ready for integration—whether for rapid prototyping or full-scale production.
