First, the parting agent shall be applied on the prepared moulds; then resin liquid mixed with curing agent shall be applied on the fiberglass materials paved layer by layer on moulds to impregnate materials, and the application thickness shall reach the design thickness and moulded products can be formed through solidification and demoulding. This moulding process has no dimension limit and the mould material is relatively cheap, so it has some advantages in large-sized product manufacturing.
