Methods of Using Retrofitted Injection Molding Machines with Reduced Pressures

摘要

An injection molding machine that uses a mold and a native controller to operate according to an original mold cycle to mold plastic objects is retrofitted with a retrofit controller; the retrofitted machine uses the mold and the retrofit controller to operate according to a retrofit mold cycle to mold plastic objects. The retrofit mold cycle has a maximum injection pressure that is less than a maximum injection pressure of the original mold cycle. The retrofit mold cycle can also have more constant injection pressures than the original mold cycle.

1. A method of using an injection molding machine, the method comprising:
first, injection molding using a first injection molding machine, a first mold, and a native controller to injection mold production versions of a plastic object according to an original mold cycle for the first mold, the first injection molding machine including an injection unit, a nozzle in fluid communication with the injection unit, and the first mold, which is in fluid communication with the nozzle, wherein the native controller is programmed with at least a portion of the original mold cycle, wherein the original mold cycle has a maximum original injection pressure, and wherein the native controller at least partially controls injection pressures of the machine according to the original mold cycle; and second, injection molding using a second injection molding machine, a second mold, and a retrofit controller to injection mold production versions of the plastic object according to a retrofit mold cycle for the second mold, the second injection molding machine including an injection unit, a nozzle in fluid communication with the injection unit, and the second mold, which is in fluid communication with the nozzle, wherein the retrofit controller is programmed with at least a portion of the retrofit mold cycle, wherein the retrofit mold cycle has a maximum retrofit injection pressure, and wherein the retrofit controller at least partially controls injection pressures of the machine according to the retrofit mold cycle; wherein the maximum retrofit injection pressure is 10-60% less than the maximum original injection pressure.
