Our GLL auto pump flange is made of high-strength steel alloy material. Through unique heat treatment process and component optimization, the tensile strength is increased to more than 1200MPa while ensuring lightweight, and the corrosion resistance and high temperature resistance are far higher than the industry average. Combined with CNC precision turning technology, the material utilization rate is increased by 30%, and the processing surface roughness is close to Ra0.4μm, which is far lower than the Ra1.6μm standard of traditional processes, ensuring that the sealing of the flange, pump body and pipeline reaches the "zero-sparse" level.
GLL CNC precision machining's core advantage : full-link control from design to mass production
Millimeter-level precision control: Using a five-axis linkage CNC machining center, the one-time molding of complex curved surfaces is achieved through programming, the axial runout is controlled within 0.01mm, and the end face parallelism error is ≤0.02mm, which completely solves the problem of precision attenuation caused by multiple clamping in traditional processes.
Quick response customization capability: Relying on the digital design system (CAD/CAM), GLL can complete the conversion from customer drawings to processing codes within 48 hours, support flexible production of small batches and multiple varieties, and meet the personalized needs of new energy vehicles, engineering machinery and other fields.
Full-process quality traceability: Each flange is equipped with a unique laser-engraved ID code, and is 100% inspected by a three-coordinate measuring machine (CMM) and a spectrometer. The data is uploaded to the cloud in real time to ensure full traceability from raw materials to finished products.
