CYLINDER HEAD COVER (CHC):
Less part weight is important for the energy consumption, most of the cylinder head cover part is made by plastic (PA66+GF) from initial material (aluminum or steel).
But the part is so important for the engine function such as - air flow & sealing, and there’s lot of features for assembly with child parts, requirement of the part quality is very high.
We need consider filling, venting, warpage of the part itself, and cycle time of the tool. It’s always tricky to build this kind of mold. Mold flow analythis kind of part is necessary, and very important for tool making, to shorten lead time of the tool development. And this is the core competition of BELLE mold after long time working with our top-level worldwide customers.
