Patent ID: 6875383

Claim:
A method for sequentially injecting a molten material comprising: clamping a stationary platen and a movable platen at a clamping force to define at least two mold cavities; injecting a molten material into a first mold cavity at a fill rate to fill and pack said cavity with said molten material, said molten material being injected into said first mold cavity by an injection pressure that is applied to said molten material; holding molten material in said first mold cavity; injecting molten material into a second mold cavity to fill and pack said cavity with said molten material; and holding molten material in said second mold cavity, wherein the injection pressure that is applied to the molten material during the step of injecting the molten material into the first mold cavity is reduced before commencing the step of injecting the molten material into the second mold cavity.
