Sand Casting; Exhaust manifold Size: 6.5kg, **0x**0x**0mm; Industry: Automotive; Material: Ductile iron, BS **0/3; Application: Exhaust manifold, replacement part; Process: Mould and fixture production. Project required precise core production, in resin sand, to meet thin wall thickness and curvature requirements whilst guaranteeing the flange angles. A specialized fixture was produced for final machining. Parts were annealed and then normalized after machining; Testing: Material composition and mechanical properties, 5 bar water leakage test; Machining: Milling, drilling and threading; Surface finish: Shot-blast & anti rust oil coating; Packing: Standard packing in plywood boxes
