Many automobile industries prefer inlet manifolds cast out of aluminium. It requires 100 % pressure testing and the cast manifold should withstand pressure of 6 bar.
Aluminium Inlet Manifolds manufactured by Alpha Engineering Company provide excellent pressure tightness along with zero leakage through body of the manifold. The manifolds are heat treated for better physical properties and sound grain structure.
We at Alpha Engineering Company provide full finished aluminium inlet manifolds with 100% pressure testing
