Question

Match the following products with preferred manufacturing processes: Product Process P Rails 1 Blow molding Q Engine crankshaft 2 Extrusion R Aluminium channels 3 Forging S PET water bottles 4 Rolling

Correct answer (B) P-4, Q-3, R-2, S-1 Solution The correct matching of products with their manufacturing processes is: Rails (P) : Typically manufactured using Rolling (4) to achieve long, continuous shapes. Engine crankshaft (Q) : Typically manufactured using Forging (3) to ensure high strength and fatigue resistance. Aluminium channels (R) : Typically manufactured using Extrusion (2), which is ideal for creating complex cross-sections in ductile materials like aluminium. PET water bottles (S) : Manufactured using Blow molding (1), specifically stretch blow molding. Matching: P-4, Q-3, R-2, S-1. This corresponds to option (B). Turn this into a strength.
