Abstract
A control system for use with a multi-layer molding device having an inspection device for measuring a characteristic of a product of a cavity of the molding device and a controller adapted to receive information corresponding to the at least one characteristic from the inspection device and to alter the molding device based on the information.
Claims46
A method of operating a molding device having at least one cavity, comprising:
- measuring at least one characteristic of a first molded product from a first injection of material into a first cavity of the at least one cavity;
- measuring at least one characteristic of a second molded product from a second injection of material into the first cavity;
- calculating a parameter based on the at least one characteristic of the first molded product and the at least one characteristic of the second molded product;
- modifying, based at least in part on the parameter, the molding device;
- and
- after modifying the molding device, producing a third molded product, whereby the third molded product is different than it would have been before modifying.

A control system for use with a molding device having at least one cavity, comprising:
- an inspection device adapted to measure at least one characteristic of a first molded product from a first injection of material into a first cavity of the at least one cavity;
- the inspection device adapted to measure at least one characteristic of a second molded product from a second injection of material into the first cavity;
- and
- a controller configured and arranged to calculate a parameter based on the at least one characteristic of the first molded product and the at least one characteristic of the second molded product, and to modify the molding device based at least in part on the parameter, whereby at least one characteristic of a third molded product produced after modification is different than it would have been before the modification.

A control system for use with a molding device having a plurality of cavities, comprising:
- an inspection device adapted to measure a characteristic of a first molded product from a first injection of material into one of the plurality of cavities;
- the inspection device adapted to measure a characteristic of a second molded product from a second injection of material into one of the plurality of cavities;
- and
- a controller configured and arranged to calculate a parameter based on the characteristic of the first molded product and the characteristic of the second molded product, and to modify the molding device based at least in part on the parameter, whereby a characteristic of a third molded product produced after modification from a third injection of material into one of the plurality of cavities is different than it would have been before the modification.
