Patent ID: 6839608

Claim:
A method of determining at least one of mechanical properties and processing properties of an injection-molded part comprising: (a) providing a hybrid model comprising, (i) a first database ( 12 ) for storing a relationship between commercial injection molded products and the respective components of the commercial products, (ii) a means (1) for inputting recipe parameters of commercial products which specify the composition of the injection-molded part, (iii) a means for accessing the first database for the purpose of determining component parameters from the recipe parameters, and (iv) at least one neural network for inputting at least one component parameter and for outputting a forecast value; (b) selecting recipe parameters and component parameters; (c) inputting recipe and component parameters into said hybrid model; and (d) obtaining at least one of a forecast and a calculated value of at least one property of said injection-molded part.
