Abstract
A thermal management system that provides metal mold surface temperature control using cyclic process thermodynamics to enhance plastic material flow and curing conditions making it possible to produce resin rich molded plastic surfaces without micro cracks or fissures to which contaminant particles can adhere or to which dirt can attach.
Claims8
A method for creating finished injection molded parts consisting of:
- a) Using conformal heating/cooling channels to heat/cool a mold core(s) and a mold cavity or cavities;
- b) Using a heat exchanger with each of the mold core(s) and mold cavity or cavities;
- c) Preheating the mold core(s) and mold cavity or cavities;
- d) Injecting plastic into the mold cavity or cavities;
- e) Cooling the mold core(s) and mold cavity or cavities using the heat exchanger(s);
- f) Reheating the mold core(s) and/or the mold cavity or cavities near Tg of the plastic;
- g) Cooling the mold using the heat exchanger(s) to form a plastic molded part;
- h) Ejecting the plastic molded part;
- thereby creating a finished plastic part.
