Controlled OEM Production Process
Design and DFM Review: Engineers analyze blade geometry, wall thickness transitions, draft angles, machining allowances, and datum points to mitigate shrinkage and porosity risks before tooling release.
Tooling and Simulation: Mold design is tailored to the selected casting process. Solidification simulation software optimizes gating and riser layouts.
Alloy Melting and Casting: Chemical composition is verified via optical emission spectrometry. Degassing and melt refinement controls ensure low-gas content prior to pouring.
As-Cast Inspection: Castings are inspected for surface defects, cold shuts, and dimensional compliance. Non-destructive testing (NDT) like X-Ray or Dye Penetrant Inspection is conducted when specified.
CNC Machining: Precision turning, boring, and milling establish tight bore tolerances, accurate keyway alignment, and true mounting faces aligned with drawing datums.
Dynamic Balancing: Finished impellers undergo dynamic balancing to meet ISO 1940 G2.5 or G6.3 standards, preventing pump bearing wear and vibration during operation.
Final QA and Documentation: Components undergo CMM dimensional checks, balancing certification, surface finish verification, and secure export packaging.
