Mold tool system having manifold body including uninterrupted melt channels
View Patent ↗A mold-tool system is provided which includes a manifold body including an inlet assembly, a plurality of outlets spaced from the inlet assembly, and an uninterrupted melt channel associated with each outlet and extending between the inlet assembly and its associated outlets. Each melt channel may have a length which is substantially identical to the length of the other melt channels.
1. A mold-tool system comprising:
a manifold body comprising:
a plurality of inlets;
a plurality of outlets spaced from the plurality of inlets; and
for each inlet, an associated melt channel that extends uninterrupted between that inlet and a corresponding one of the outlets, wherein that inlet and the corresponding outlet are dedicated to the associated melt channel.
2. The mold-tool system of claim 1 , further comprising:
a melt-distribution assembly, the melt distribution assembly comprising:
an upper melt-distribution assembly including uninterrupted melt channels;
a plurality of lower melt-distribution assemblies each including uninterrupted melt channels;
an upper melt splitting device, and
a plurality of lower melt splitting devices;
the upper melt splitting device being coupled to the upper melt-distribution assembly and the plurality of lower melt splitting devices connecting the upper melt-distribution assembly to the plurality of lower melt-distribution assemblies,
at least one of the upper melt-distribution assembly and the lower melt-distribution assembly including the manifold body.
3. The mold tool system of claim 1 , wherein there is no mixing of melt in one of the associated melt channels with melt in another of the associated melt channels.
4. The mold tool system of claim 1 , wherein each of the associated melt channels has no split in the flow of a melt flowing along the associated melt channels.
5. The mold tool system of claim 1 , wherein the thermal profiles at each outlet are substantially similar.
6. A mold-tool system comprising:
a manifold body comprising:
a plurality of inlets;
a plurality of outlets spaced from the plurality of inlets; and
a plurality of uninterrupted melt channels extending between the plurality of inlets and the plurality of outlets, each of the uninterrupted melt channels being associated with only one inlet and only one outlet, wherein the plurality of melt channels includes at least a first melt channel having a first length, and a second melt channel having a second length, wherein the first length is substantially identical to the second length.
7. The mold-tool system of claim 6 , wherein each of the plurality of melt channels has a substantially uniform length.
8. The mold tool system of claim 6 , wherein the thermal profiles at each outlet are substantially similar.
