A detailed infographic illustration breaking down the 10 key stages of manufacturing a RAFSUN branded pump. The visual journey starts with a person researching 'Design & Engineering' at a desk, followed by 'Pattern Making' for casting molds. Stage 3 shows 'Casting & Molding' molten metal being poured. Next, industrial arms work in 'Machining' before 'Impeller Fabrication.' At stage 6, workers do 'Shaft & Bearing Assembly,' followed by robots in 'Coil Winding & Motor Assembly.' Stage 8 depicts 'Assembly & Integration' of the main body and motor. A Quality Control technician conducts 'Performance Testing' with pressure gauges. The final stage 10 shows a forklift moving 'Final Inspection & Packaging' boxes clearly marked 'RAFSUN' onto a truck. Each icon is sequentially numbered from 1 to 10 with a corresponding descriptive title for the manufacturing step.
