Abstract
A method and system for adjusting melt pressure in an injection molding material that allows calculating a melt pressure of a molten plastic material to be injected and based on the calculated melt pressure and a desired melt pressure adjusting operation of an injection molding machine. This control of an injection molding cycle using the method and system of plastic melt pressure determination allows production of parts of increased quality and consistency.
Claims20
A method of adjusting melt pressure in an injection molding machine, the method comprising:
- measuring, by a sensor of the injection molding, a property associated with an injection of a polymeric material being injected by the injection molding machine;
- based on the measured property, calculating a value indicative of a melt pressure of the polymeric material being injected by the injection molding machine;
- based on the value indicative of the melt pressure and a desired melt pressure of the polymeric material as a function of time, adjusting operation of the injection molding machine, wherein adjusting operation of the injection molding machine adjusts the injection of the polymeric material in an effort to minimize any difference between the melt pressure and the desired melt pressure.
A system for adjusting melt pressure during injection molding, the system comprising:
- an injection molding machine comprising:
- an injection unit configured to inject a polymeric material, and
- a sensor configured to measure a property associated with the injection of the polymeric material;
- and
- a controller communicatively coupled to the injection molding machine and configured to:
- based on the measured property, calculate a value indicative of a melt pressure of the polymeric material, and
- based on the value indicative of the melt pressure and a desired melt pressure of the polymeric material as a function of time, adjust operation of the injection molding machine, wherein adjusting operation of the injection molding machine adjusts the injection of the polymeric material in an effort to minimize any difference between the melt pressure and the desired melt pressure.
