This dialog is used to view the properties of the selected thermoplastics material.
The Recommended Processing tab of the Thermoplastics material dialog is used to specify the recommended processing conditions for the thermoplastics material.
Note: Once an analysis is finished, you can check the ejection temperature, maximum shear stress and rate against the analysis results to determine if they are acceptable.
Note: If a property name is shown in red, it indicates that the property has not been tested for this specific material. However, material data from the testing of a comparable generic grade was found to be suitable and has been assigned to this material.
Dialog elements
- Mold surface temperature
- The temperature of the mold at the plastic-metal interface, where the plastic touches the mold.
In cases where this is an input box, enter the required mold temperature.
Note:
- The temperature of the mold affects the cooling rate of the plastic.
- The mold temperature cannot be higher than the ejection temperature.
- Melt temperature
- The temperature of the molten plastic, or melt, as it starts to flow into the cavity.
In cases where this is an input box, enter the required melt temperature.
Note:
- If the model has a runner system, the melt temperature refers to the temperature of the melt as it enters the runner system. If the model does not have a runner system, the melt temperature is the temperature of the melt as it exits the gate(s).
- The melt temperature cannot be lower than the Transition temperature.
- Mold temperature range (recommended)
- The Mold Temperature area displays the range of mold wall temperatures that can be used for the material.
The minimum mold wall temperature is displayed in the Minimum box, and the maximum mold wall temperature is displayed in the Maximum box.
- Melt temperature range (recommended)
- The Melt Temperature area displays the range of melt temperatures that can be used for the material.
The minimum processing temperature of the material is displayed in the Minimum box, and the maximum processing temperature of the material in the Maximum box.
- Absolute maximum melt temperature
- The highest temperature recommended by the manufacturer for the material melt process settings.
Processing at the Absolute maximum melt temperature may require special precautions and reduced residence times. Refer to the resin manufacturer processing specifications for more detailed advice on processing temperatures.
- Ejection temperature
- The temperature at which a material is rigid enough to withstand ejection without permanent deformation or severe marking from the mold ejector pins.
In cases where this is an input box, enter the temperature at which you want the part ejected from the mold.

- Maximum shear stress
- The shear stress, specific for each material, beyond which material degradation starts to occur.
Tip: After an analysis is complete, you can check the resultant shear stress against this value to determine whether shear stress is acceptable in your design.
- Maximum shear rate
- The shear rate value, specific for each material, beyond which material degradation starts to occur.
Tip: After an analysis is complete, you can check the resultant shear rate against this value to determine whether shear rate is acceptable in your design.
