TOP Rated 6 Cylinder Head Manufacturers & Suppliers And Manufacturing Process

What is a Cylinder Head?

Any idea what is the role of a cylinder head inside your engine? A cylinder head is commonly seated on the top of the engine block. It houses different engine components including intake and exhaust valves, springs and lifters, as well as the combustion chamber. The most common materials used by cylinder head manufacturers are steel and aluminum.

The Cylinder head is design to have port ways or passages. The passages allow the cylinder head to enable the air and fuel to flow inside the cylinder while permitting the exhaust gasses to flow outside. The port ways also serve as a channel for the coolant to reach the engine block that cools down engine components. As said earlier, a cylinder head is seated on the of the engine block. Thus, a gap is present. The cylinder head gasket aids this gap to prevent water or oil leaks that might compromise the engine’s health and performance.

Cylinder Head Manufacturing Process: How are Cylinder Heads Made?

cylinder head manufacturing

Cylinder head manufacturers can use different methods to make the product: lost foam method, permanent mold casting, sandcasting, and pressure die casting.

The lost foam process is the most popular. There are many reasons for that. The method follows a simple process, which saves on the manufacturing costs and time. It also allows the casting of complicated cylinder head designs to suit the modern engine.

Cylinder head manufacture using the lost form process follows this sequence.

  • The cylinder head pattern is made by gluing together layers of foaming polystyrene
  • The construction is then coated in ceramic and dried using an airflow
  • The structure is placed in a flask
  • Sand is poured into the structure to fill all the spaces in the pattern
  • The sand is then compacted to firmly take up the spaces. This forms the mold
  • Molten cylinder head material is then poured into the mold
  • The heat of the molten metal evaporates the polystyrene material
  • The molten metal dries up, taking the shape of the mold or cylinder head structure
  • The casting is then washed to remove the sand
  • After that, the cylinder head block is machined to the required specifications
  • Later, various cylinder head parts such as valve seals and valve seats are fitted
