Method for forming an integral faucet core assembly

A method for forming an integral faucet core assembly, which is especially applied to said integral faucet core assembly in a double handle type, comprising steps of:

• step 1:
• utilizing a die for one-time molding that includes two inlet cores, at least one outlet core, at least one middle fluid channel core, and two valve cores axially aligned with said inlet cores and disposed opposite thereto;
• a body having two inlet channels, at least one outlet channel, and at least one middle fluid channel so as to construct an integral faucet canal via said two inlet channels, said at least one middle fluid channel, and said at least one outlet channel of said body intercommunicated with each other after drawings of said die and said cores;
• two valve holes, which function to receive said valve cores, being axially formed at a direction opposite to said inlet channels of said body to intercommunicate with said inlet channels and said middle fluid channel;
• said middle fluid channel and said two inlet channels being arranged perpendicular to each other;
• an inlet being formed at an exterior of said inlet channel, an outlet being formed at an exterior of said outlet channel, and a core-pulling hole being formed at an exterior of said middle fluid channel after each of said cores being taken out;
• using a plug die for molding a plug capable of densely sealing said core-puling hole;
• step 2:
• installing said plug and a sealing ring into said core-pulling hole of said body so as to construct an insert for an over molding;
• and
• step 3:
• placing said insert into a die for over molding;
• wrapping said insert in a covering that is capable of keeping said plug located in correspondence with said body, so that said integral faucet canal core in a double handle type being formed after drawing the die for over molding.

A method for forming an integral faucet core assembly, which is especially applied to said integral faucet core assembly in a single handle type, comprising steps of:

• step 1:
• utilizing a die for one-time molding that includes two inlet cores, two outlet cores, and two middle fluid channel cores;
• a body having two inlet channels, two outlet channels, and two middle fluid channels so as to form twin faucet canals by respectively connecting said inlet channels to said middle fluid channels and said outlet channels of said body after drawings of said die and said cores;
• said middle fluid channels and said two inlet channels being arranged perpendicular to each other;
• an inlet being formed at an exterior of said inlet channel, an outlet being formed at an exterior of said outlet channel, and a core-pulling hole being formed at an exterior of said middle fluid channel after each of said cores being taken out;
• using a plug die for molding a plug capable of densely sealing said core-puling hole;
• step 2:
• installing said plug and a sealing ring into said core-pulling hole of said body so as to construct an insert for an over molding;
• and
• step 3:
• placing said insert into a die for over molding;
• wrapping said insert in a covering that is capable of keeping said plug located in correspondence with said body, so that the integral faucet canal core in said single handle type is formed after drawing said die for over molding.
