초록 ▼

A method of forming includes the steps of: placing a first mold member and a second mold member in contact with one another; injecting a first material into a first recess in the first mold member to form a first portion of a midsole while the first mold member is maintained at a temperature below an ambient temperature; removing the first portion of the midsole from the first recess; positioning the first portion of the midsole in the second recess in the third mold member of the second mold assembly; placing a second material into the second recess in contact with the first portion of the midsole; placing the third mold member and the fourth mold member in contact with one another; and subjecting the second material and the first portion in the second mold assembly to heat and pressure to form a midsole.

1. A method of forming a midsole with a first mold assembly having a first mold member and a second mold member with a first recess formed in the first mold member, and a second mold assembly having a third mold member and a fourth mold member with a second recess formed in the third mold member, comprising the steps of: placing the first mold member and the second mold member in contact with one another;injecting a first material into the first recess in the first mold member to partially cure and form a first portion of a midsole while the first mold member is maintained at a temperature below an ambient temperature;removing the first portion of the midsole from the first recess;positioning a second material and the first portion of the midsole in contact with one another in the second recess in the third mold member of the second mold assembly;placing the third mold member and the fourth mold member in contact with one another; andsubjecting the second material and the first portion in the second mold assembly to heat and pressure such that the first material completely cures and the first portion and the second material bond to form a midsole. 2. The method of forming a midsole of claim 1, wherein the first mold member includes at least one additional first recess, an additional first portion of a midsole being formed in each additional first recess; and wherein the third mold member includes at least one additional second recess, an additional midsole being formed in each additional second recess. 3. The method of forming a midsole of claim 1, wherein the first portion comprises a heel portion of a midsole. 4. The method of forming a midsole of claim 1, wherein the first portion comprises a forefoot and midfoot portion of a midsole. 5. The method of forming a midsole of claim 1, wherein the first material has a first density and the second material has a second density that is different than the first density. 6. The method of forming a midsole of claim 1, wherein the first material has a first hardness and the second material has a second hardness that is different than the first hardness. 7. The method of forming a midsole of claim 1, wherein the second material is placed in the second recess in the form of pellets. 8. The method of forming a midsole of claim 1, wherein the first mold member of the first mold assembly includes a channel, the channel extending between the first recess and an exterior of the first mold member. 9. The method of forming a midsole of claim 8, wherein the first material is injected into the first recess through the channel. 10. The method of forming a midsole of claim 1, wherein the first material is EVA. 11. The method of forming a midsole of claim 1, wherein the second material is EVA. 12. The method of forming a midsole of claim 1, wherein the second material is a second portion of a midsole. 13. The method of forming a midsole of claim 12, further comprising the step of forming the second portion of the midsole in a cold molding process. 14. A method of forming a midsole with a first mold assembly having a first mold member and a second mold member with a first recess formed in the first mold member, and a second mold assembly having a third mold member and a fourth mold member with a second recess formed in the third mold member, comprising the steps of: placing the first mold member and the second mold member in contact with one another;injecting a first material having a first density into the first recess in the first mold member to partially cure and form a first portion of a midsole while the first mold member is maintained at a temperature below an ambient temperature;removing the first portion of the midsole from the first mold member;positioning the first portion of the midsole in the second recess in the third mold member;placing pellets of a second material having a second density that is different from the first density into the second recess in contact with the first portion of the midsole;placing the third mold member and the fourth mold member in contact with one another; andsubjecting the second material and the first portion in the second mold assembly to heat and pressure such that the first material completely cures and the first portion and the second material bond to form a midsole. 15. The method of forming a midsole of claim 14, wherein the first mold member includes at least one additional first recess, an additional first portion of a midsole being formed in each additional first recess; and wherein the third mold member includes at least one additional second recess, an additional midsole being formed in each additional second recess. 16. The method of forming a midsole of claim 14, wherein the first portion comprises a heel portion of a midsole. 17. The method of forming a midsole of claim 14, wherein the first portion comprises a forefoot and midfoot portion of a midsole. 18. The method of forming a midsole of claim 14, wherein the first mold member of the first mold assembly includes a channel, the channel extending between the first recess and an exterior of the first mold member. 19. The method of forming a midsole of claim 18, wherein the first material is injected into the first recess through the channel. 20. The method of forming a midsole of claim 14, wherein the first material is EVA. 21. The method of forming a midsole of claim 14, wherein the second material is EVA.
