Abstract
A molding system and a method for operation of the molding system are provided. The method includes flowing a molten polymeric material into a shot tuning chamber from an upstream device, adjusting a temperature of and/or pressure applied to the molten polymeric material in the shot tuning chamber, and flowing the molten polymeric material from the shot tuning chamber into a mold cavity.
Claims20
A system comprising:
- a shot tuning chamber configured to receive a molten polymeric material from an upstream device, to adjust one or more of a temperature of and a pressure applied to the molten polymeric material to create an adjusted molten polymeric material, and to dispense the adjusted molten polymeric material.
A method for operation of a molding system, the method comprising:
- flowing a molten polymeric material into a shot tuning chamber from an upstream device;
- adjusting a temperature, a pressure, or both, within the shot tuning chamber to create a tuned molten polymeric material;
- and
- flowing the tuned molten polymeric material into a mold cavity from the shot tuning chamber.
A molding system comprising:
- a device configured to receive a polymeric material and heat the polymeric material to form a molten polymeric material;
- a shot tuning chamber configured to receive the molten polymeric material from the device and adjust a temperature of or a pressure applied to the molten polymeric material;
- and
- an adjustable mold runner configured to regulate flow of the molten polymeric material between the shot tuning chamber and a mold cavity;
- and
- a temperature and pressure control assembly coupled to the shot tuning chamber and configured to adjust the pressure applied to and/or the temperature of the molten polymeric material in the shot tuning chamber;
- where the molten polymeric material includes a dissolved blowing agent, and the dissolved blowing agent and the molten polymeric material form a molten single phase solution (SPS).
