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 and to dispense an adjusted molten polymeric material to a mold cavity of a mold, the shot tuning chamber comprising:
- a temperature sensor and a pressure sensor to detect a temperature and pressure of a molten polymeric material;
- a temperature control assembly having a coolant loop traversing a housing of the shot tuning chamber configured to adjust a temperature of the molten polymeric material;
- and
- a pressure control assembly configured to adjust a pressure applied to the molten polymeric material, wherein the temperature control assembly and the pressure control assembly are configured to create the adjusted molten polymeric material.

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 dispense an adjusted molten polymeric material to a mold cavity of a mold, the shot tuning chamber comprising:
- a temperature sensor and a pressure sensor to detect a temperature and pressure of the molten polymeric material;
- a temperature control assembly having a coolant loop traversing a housing of the shot tuning chamber configured to adjust a temperature of the molten polymeric material;
- and
- a pressure control assembly configured to adjust a pressure applied to the molten polymeric material, wherein the temperature control assembly and the pressure control assembly are configured to create the adjusted molten polymeric material;
- and
- an adjustable mold runner configured to regulate flow of the adjusted molten polymeric material between the shot tuning chamber and a mold cavity of a mold.
