Abstract

A method of manufacturing an injection molded product. Thermoplastic is injected through a runner system and into a gate member. The gate member is generally V-shaped and thermoplastic is displaced through the gate into a mold cavity at a nearly perpendicular angle to the surface of the indicia carrier to hold the indicia carrier against the mold cavity. This allows the indicia carrier to be fused to the thermoplastic body during the making of a product.

Claims (16)

1. A method of manufacturing an injection molded product, steps comprising:

placing a first indicia carrier having a planar surface on a front side of a mold cavity;

injecting thermoplastic through a runner system to a gate member having a first and second section;

displacing the thermoplastic into the mold cavity through the first and second sections of the gate member into a mold wherein the second section is angled such that the thermoplastic is displaced onto an edge of the indicia carrier nearly perpendicular to the planar surface of the indicia carrier to hold the indicia carrier in position against the mold cavity; and

fusing the first indicia carrier to the thermoplastic.

2. The method of claim 1 wherein the first section tapers toward the second section.

3. The method of claim 2 wherein the second section tapers toward the mold.

4. The method of claim 1 wherein the first indicia carrier is a label.

5. The method of claim 1 wherein during the displacing step the thermoplastic flattens all wrinkles and pockets of air from under the first indicia carrier.

6. The method of claim 1 wherein the first indicia carrier has radio frequency identification thereon.

7. The method of claim 1 further comprising the step of:

holding a second indicia carrier against the mold cavity with the thermoplastic; and

fusing the second indicia carrier to the thermoplastic.

8. The method of claim 7 wherein the first indicia carrier has man readable indicia thereon.

9. The method of claim 8 wherein the second indicia carrier has a radio frequency identification thereon.

10. The method of claim 7 wherein the first indicia carrier has a radio frequency identification thereon.
