Exhaust Gas Manifold

The exhaust gas manifold is used in commercial vehicles or heavy machinery and is characterized by high temperatures. Therefore, there are specific requirements for material and hardness. Inspections will be conducted during the incoming material inspection and machining processes to ensure the workpiece achieves the required precision, with a surface roughness (Ra) of less than 1.6µm and dimensional and shape tolerances of less than 15µm. Recommended materials include high-silicon molybdenum ductile iron or gravity casting aluminum alloy, which can meet the high-temperature resistance characteristics required for exhaust gas recirculation manifolds.

What is CNC machining?

Metal forming is the process of pouring molten metal into molds and shaping it. Common methods of metal forming include:

1.Sand casting - Pouring molten metal into sand molds to solidify into shape.
2.Die-casting - Injecting molten metal under high pressure into metal molds to shape it.
3.Gravity casting - Also known as permanent mold casting, it involves filling metal molds with molten metal using gravity to shape it.
4.Lost wax casting - Also known as investment casting, pouring molten metal into wax molds to shape it.
5.Forging - Using molds and applying high temperature and pressure to deform aluminum into the desired shape.
6.Extrusion - Using molds and applying pressure to force aluminum through openings to shape it.

The choice of forming method depends on the material, the final application of the workpiece, and the quantity of production. WEIYU has decades of experience in metal forming and integrates both in-house and external resources to provide a wider range of metal forming services of various materials, creating value for the mass production of metal parts.
