Quality Assurance & Precision Testing Capabilities
DHDT strictly adheres to the ISO 9001 Quality Management System, performing comprehensive internal testing on all custom round and flat wire products to ensure they fully comply with customer specifications and the highest industry standards.
Core Testing Capabilities
▪ Dimensional Inspection: Utilizing high-resolution equipment with a measurement resolution of 0.000254 mm and a system accuracy of ±0.00127 mm. For ultra-tight tolerance requirements, we utilize diamond dies for ultra-fine drawing to achieve superior dimensional accuracy and surface finish.
▪ Tensile Testing: We use high-precision tensile testers to verify tensile strength with a measurement accuracy of ±1%. Actual strength labeling per batch is available upon request.
▪ Electrical Resistance: We measure resistance with 0.01% accuracy to ensure conductive performance meets design requirements.
▪ Plating Thickness: High-precision thickness gauges measure various metal coatings (Gold, Silver, Nickel, Tin, etc.) to ensure consistency in conductivity, corrosion resistance, and solderability.
▪ Environmental Reliability: We offer temperature resistance testing (-20°C to 350°C) and salt spray testing to evaluate long-term performance and corrosion resistance in harsh environments.
We ensure all sourced materials comply with DFARS, REACH, and RoHS. DHDT is ITAR registered, meeting the strict regulatory standards of the aerospace and defense industries.
