multiple outlets spaced from the single inlet, the outlets being configured for fluid communication with the melt distribution device;

a plurality of uninterrupted melt channels, each melt channel extending from the inlet to an associated one of the outlets; and

a melt splitting device body having a substantially cone-shaped melt splitter communicating with the inlet for splitting the melt and directing the melt to the uninterrupted melt channels.

2. The mold-tool system of claim 1 , wherein:

the melt distribution device includes a manifold assembly.

3. The mold-tool system of claim 2 , wherein:

the melt splitting device includes a material that has a thermal conductivity that is different from a thermal conductivity of a material included in the manifold assembly.

4. The mold-tool system of claim 2 , wherein:

the melt splitting device includes a material that has a fatigue strength that is different than a fatigue strength of a material included in the manifold assembly.

5. The mold-tool system of claim 1 , wherein:

the melt splitting device is configured to change direction of a melt flow from a cylindrical flow to an annular flow before the melt flow enters the melt channels.

6. The mold-tool system of claim 1 , wherein each of the outlets has a similar melt flow front profile.

7. The mold-tool system of claim 1 , wherein the melt channels radiate symmetrically, radially, outwardly along an acute angle relative to a central axis of the inlet.

8. The mold-tool system of claim 1 , wherein the melt splitting device includes an upper body that includes the inlet, and a lower body that includes the melt channels and the outlets.

9. A mold-tool system comprising:

a manifold assembly having a plurality of inlets and a plurality of outlets, each inlet of the manifold assembly being in communication with an associated outlet through a dedicated, uninterrupted melt channel;

a melt splitting device, the melt splitting device comprising:

a single inlet;

a plurality of outlets spaced axially from the inlets;

a plurality of uninterrupted melt channels, each melt channel in the melt splitting device extending from the inlet to an associated one of the outlets to provide a flow of a melt from the inlet to the associated outlet without mixing with melt in other melt channels; and

a melt splitting device body having a substantially cone-shaped melt splitter communicating with the inlet for splitting the melt and directing the melt to the uninterrupted melt channels,

each outlet of the melt splitting device communicating with an associated inlet of the manifold assembly.

10. The mold-tool system of claim 9 , further comprising:

a connection hole disposed in the melt splitting device; and

a connection device extending through the connection hole and into the manifold assembly to attach the melt splitting device to the manifold assembly.

11. The mold-tool system of claim 10 , further comprising a plug in the melt splitting device to seal and divert melt flow in the melt channels of the melt splitting device.

12. The mold-tool system of claim 9 , wherein the melt splitting device comprises six melt channels and six outlets.

13. The mold-tool system of claim 9 , wherein the melt splitting device comprises 12 outlets and 12 melt channels.

14. A melt splitting device configured to interact with a melt distribution device, the melt splitting device comprising:

a single inlet, the single inlet having a central axis;

multiple outlets spaced from the single inlet, the outlets being configured for fluid communication with the melt distribution device;

a plurality of uninterrupted melt channels, each melt channel extending from the inlet to an associated one of the outlets, wherein the plurality of uninterrupted melt channels radiates symmetrically, radially, outwardly from the central axis of the single inlet; and

a melt splitting device body having a substantially cone-shaped melt splitter communicating with the inlet for splitting the melt and directing the melt to the uninterrupted melt channels.

15. A mold-tool system, comprising:

a melt splitting device configured to interact with a melt distribution device, the melt splitting device comprising:

a single inlet, the single inlet having a central axis;

multiple outlets spaced from the single inlet, the outlets being configured for fluid communication with the melt distribution device;

a plurality of uninterrupted melt channels, each melt channel extending from the inlet to an associated one of the outlets; and

an outlet body which defines at least a portion of the melt channels, the outlet body having an apex, wherein the apex is positioned substantially along the central axis of the single inlet.
