Method for manufacturing an anchor device

A method for manufacturing an anchor device having an elongated insert with a plurality of rib members extending radially therefrom and an attachment seat integrally formed on an upper end of said insert, said method comprising:

• providing an elongated mold having an axial hole formed along a longitudinal axis thereof, a plurality of grooves extending radially from the axial hole, each of the grooves having a width which increases gradually in a direction from a first end to a second end of the axial hole, and an enlarged receiving space formed adjacent to the second end of the axial hole;
• disposing a metal shaft having a tapered end and a head end in the axial hole so that the head end extends into the enlarged receiving space;
• and
• injecting a molten plastic material into the mold around the metal shaft in order to fill the grooves and the receiving space so as to form said insert and said attachment seat of said anchor device;
• moving a forming die into the enlarged receiving space to depress the molten plastic material of the attachment seat into a plurality of sidewalls and thus form an opening upon which a post may be set;
• retracting the forming die from the mold;
• and
• removing the integrally formed anchor device from the mold.
