Coextrusion Optimization
 

The Coextrusion Wizard is designed to help with the optimization of resin selection and processing conditions for multilayer flow (primarily multilayer film/sheet but also pipe, tubing etc.). It uses a theoretical model backed up by extensive laboratory testing to tackle two key problems common to the multilayer extrusion process. The first involves the optimization of layer thickness distribution across the width of the film/sheet and helps to prevent the so called "encapsulation" phenomenon. The second involves the prediction and elimination of undesirable flow lines and ripples in the sheet (i.e. "seagulls", chatter, etc) caused by flow instabilities at the interface between layers. With the wizard, one can quickly determine what problems might be encountered in a typical multi-layer application, so that the necessary steps can be taken to yield film/sheet with optimal properties.

Coolant Flow Rate Calculator
 

Mold temperature can influence the overall cycle, shrinkage, warpage, crystallinity, and other characteristics of a molded part. Amorphous Eastman polymers require colder molds than some other plastics, therefore proper attention to cooling is critical. After the mold is designed and constructed, one must insure that adequate turbulent flow is provided for the cooling channels. Turbulent coolant flow ensures optimum heat transfer as it allows more of the coolant to be exposed to the core and cavity channels.

Injection Molding Part Cost Estimation
 

The Part Cost Estimator Wizard estimates the cost of a part based on the cost of the resin, the machine time, and any secondary fabrication. With the ability to run "what if" scenarios, an injection molder can examine many facets of the process as an aid to designing a new process or optimizing an existing one.

Oxygen Limited Shelf Life Calculator
 

The Oxygen Limited Shelf Life Tool predicts oxygen ingress over the shelf life of a product packaged in a PET bottle. The tool constructs a hypothetical package based on a few user inputs and then uses a combination of historical data, theoretical models and empirical correlations to estimate oxygen ingress into this hypothetical package. The tool can be used to estimate the total oxygen exposure of the product at a target shelf life or, if the oxygen tolerance of a product is known, it can be used to predict the time to reach this oxygen exposure limit.
