DZynSource Mold Engineering Software was written by a mold designer, for his own use, to save time doing engineering calculations. As a result the software has evolved, over the last seven years, into a time saving tool that does engineering calculations and contains a wealth of engineering data from Fluid Dynamics to Thermodynamics and Strength of Materials. The topics go beyond just mold design and cover many molding and production planning modules. There are sections for machining, a hot runner checklist, material properties, and even a vent width calculator.
