Abstract

A fin is formed using a sectional mould, in which two material injecting units are provided to simultaneously inject the material for forming the fin into the mould, so that a front blade portion and a rear foot pocket portion of the fin are formed at the instant of injection to produce a complete fin. The two injecting units may be preset or adjusted to optimal injecting time and pressure according to a flow rate of the type of molten material, so that the molded blade portion and foot pocket portion are fully connected together to have the best bonding strength between them.
