Precision Engineering: The Manufacturing Process of DQ-Series Clamps

The manufacturing of the DQ-630/1200/2500 Conductor Resistance Clamp series is a testament to precision engineering, ensuring each unit meets rigorous performance and durability standards. The process begins with the careful selection of high-grade materials, primarily specialized copper alloys and stainless steel, chosen for their superior electrical conductivity, mechanical strength, and corrosion resistance. These materials undergo a multi-stage refinement process to eliminate impurities and optimize their metallurgical properties. For the core clamping components, a combination of advanced casting and forging techniques is employed. Casting ensures intricate shapes are formed with high dimensional accuracy, while subsequent forging enhances material density and grain structure, significantly improving the clamp's mechanical integrity and resistance to deformation under load.

Following the initial shaping, critical components proceed to state-of-the-art CNC machining centers. This allows for incredibly tight tolerances, ensuring perfect alignment and contact surfaces essential for accurate resistance measurements. Surface treatments, such as passivation for stainless steel and specialized plating for copper components, are then applied to further enhance corrosion resistance, particularly in harsh industrial environments like petrochemical plants or coastal installations. Every batch undergoes stringent quality control, including non-destructive testing (NDT), dimensional checks, and material composition analysis. Final product testing adheres to international standards such as ISO 9001 for quality management and ANSI standards for specific electrical components, guaranteeing a robust design life of over 10 years, even under continuous heavy-duty use. The meticulous attention to detail at every stage positions the DQ-630/1200/2500 Conductor Resistance Clamp as a benchmark for reliability and performance in its class.
