C-MOLD 3D QuickFill 99.7 Design Advice. The part(s) can be successfully filled with injection pressure of 11265 psi and clamp force tonnage of 80 ton(US). No resin degradation detected in the simulation. The required injection pressure is in a reasonable range, or 43 % of the max. injection pressure which can be delivered by a typical machine. The part thickness varies too greatly. You should design the part with more uniform thickness, to improve the filling and cooling. The part thickness can be reduced by roughly 19 % and the part will still fill. Before reducing the thickness, however, you should consider the minimum thickness required for part strength. If you reduce the thickness, rerun 3D QuickFill for updated results.
The part design was prepared as a solid model, using CAD software. An STL file was created from the solid model and was imported into C-MOLD 3D QuickFill. Runners, gates and injection points are identified within C-MOLD 3D QuickFill. ABS was selected from the personal resin database and default process conditions are used. The simulation results show how the four variables of the plastics syste m (material, part, mold, and machine) influence both part quality and cost. For example, if the part short shots, 3D QuickFill tells you the remedy options. If your design requires excessive injection pressure or melt temperature, 3D QuickFill tells you what can be done. It also tells you when, and by how much, the part's nominal wall thickness can be reduced and still be manufacturable. C-MOLD 3D QuickFill provides guidance throughout your part design cycle for decisions that influence optimal part performance. Sink marks and their magnitutde can be identified on the solid. Part warpage can be minimized by selecting gate locations which balance the filling of the mold cavity shown in the melt-front advancements. Part strength can be improved in critical areas by using the predicted orientation. Final part weight can be used along with all other information to reliably estimate part cost. The simulation results from 3D QuickFill assure that the plastic part design will be thinner, stronger, less costly, and most importantly ... manufacturable from the first trial.
Melt-front advancement: The figure above represents the melt front progression of the part during filling. The blue areas represent those areas of the part which fill first and red represents those areas which are the last to fill. A balanced fillling without hesitation is desirable.
