The method includes providing an elongated mold having an axial hole, a plurality of grooves extending radially from the axial hole, and an enlarged receiving space formed adjacent to the second end of the axial hole; disposing a metal shaft in the axial hole of the mold with an upper end of the metal shaft extending into the receiving space of the mold; injecting a molten plastic material into the mold around the metal shaft in order to fill the grooves and the receiving space; moving a forming die into the receiving space of the mold to depress the plastic material in the receiving space; and retracting the forming die from the mold and removing the integrally formed anchor device from the mold. ## Claims ### Claim 1 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 wherein the molten plastic material covers said head end of the metal shaft. ### Claim 2 (depends on 1) The method of claim 1, further comprising 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. ### Claim 3 (depends on 1) The method of claim 1, wherein said providing an elongated mold includes providing the elongated mold having a thickened portion on the plurality of groves adjacent to junctures of the rib members of the insert and the attachment seat. ### Claim 4 (depends on 1) The method of claim 1, wherein said providing an elongated mold includes providing the elongated mold having a hole shaft within the enlarged receiving space so that the attachment seat will have a hole therein. ### Claim 5 (depends on 1) The method of claim 1, wherein said disposing a metal shaft includes disposing the metal shaft having the head end in the axial hole so that the head end extends into the enlarged receiving space, the head end having a bottom surface and a block formed thereon, the block having a hole formed therein, so that attachment seat will made of metal and have a plastic coating formed thereon. ### Claim 6 (depends on 1) The method of claim 1, further comprising placing an epoxy material within any holes in the plastic insert or plastic attachment seat. ### Claim 7 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. ### Claim 8 (depends on 7) The method of claim 7, wherein said disposing a metal shaft includes disposing the metal shaft having the head end in the axial hole so that the head end extends into the enlarged receiving space, the head end having a bottom surface and a block formed thereon, the block having a hole formed therein, so that attachment seat will made of metal and have a plastic coating formed thereon. ### Claim 9 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; wherein a portion of the tapered end is not covered in the molten plastic material. ### Claim 10 (depends on 9) The method of claim 9, further comprising 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. ### Claim 11 (depends on 9) The method of claim 9, wherein said providing an elongated mold includes providing the elongated mold having a thickened portion on the plurality of groves adjacent to junctures of the rib members of the insert and the attachment seat. ### Claim 12 (depends on 9) The method of claim 9, wherein said providing an elongated mold includes providing the elongated mold having a hole shaft within the enlarged receiving space so that the attachment seat will have a hole therein. ### Claim 13 (depends on 9) The method of claim 9, wherein said disposing a metal shaft includes disposing the metal shaft having the head end in the axial hole so that the head end extends into the enlarged receiving space, the head end having a bottom surface and a block formed thereon, the block having a hole formed therein, so that attachment seat will made of metal and have a plastic coating formed thereon. ### Claim 14 (depends on 9) The method of claim 9, further comprising placing an epoxy material within any holes in the plastic insert or plastic attachment seat.
