Abstract
The application provides a forming method of a head assembly and an engine shell, and comprises the following steps: step S1, forming of a head protective layer; step S2, forming of a bottom layer of a thermal insulation layer; step S3, forming of a manual debonding layer; step S4, forming of a uniform pressure plate; and step S5, forming of a cover layer of the thermal insulation layer. The forming die of the uniform pressure plate and the upper die of the head assembly forming die share one set, so that the investment of the die is effectively reduced, and the cost is effectively reduced.
