C-MOLD Design Templates

Design templates are groups of variables that define the design information required for each individual or integrated C-MOLD analysis. The template-coding, or T-CODE, system is the foundation for organizing the templates for C-MOLD analyses. Each variable or variable set defined in the input files required for C-MOLD analyses has a unique number associated with it, called its T-CODE. Because of the T-CODE system, data for more than one type of analysis can be included in each C-MOLD input file. The design template you choose acts as a filter that allows you to see only those variables that are necessary to accomplish the design analysis you want to execute.

C-MOLD Process Estimator provides design templates for material properties and process conditions; the templates available to you depend on the mold process you select in the Control Panel. Mold processes for which C-MOLD provides analyses include injection molding, gas-assisted injection molding, reactive molding, co-injection molding, blow molding, and thermoforming. The default material properties and process conditions design templates provided in C-MOLD Process Estimator for each of these mold processes are given below.
