Abstract
A method for manufacturing hose couplings is composed of three steps as follows. The first step involves jointing and fixing a top casting-cavity insert and a bottom casting-cavity insert within a mold base of a casting machine. The second step is injecting a high-temperature molten metal into both the casting-cavity inserts, so that the molten metal can fill up the casting-cavity inserts. The third step is cooling the casting-cavity inserts by using a cooling liquid, so that the cooled and solidified metal can be released from the casting-cavity inserts to form a hose coupling. By using the method, various types of top casting-cavity inserts and bottom casting-cavity inserts may be adapted as desired and, therefore, various types of hose couplings may be manufactured as desired.
