Time is money, and time means seconds when it comes to injection molding cycle times. Reducing seconds out of a cycle time can dramatically increase the profitability of a job and lower the piece part cost. This can be accomplished by exploring cooling methods, part design, tooling changes, and machine parameters.
The main phases of injection molding are opening and closing the mold, injection, packing, cooling, and ejection. Cooling consumes the most time in the cycle thus giving a good opportunity to shave seconds out of the cycle time, however it likely comes with additional cost and this needs to be considered.
It seems obvious that you would want to produce high quality parts in the shortest amount of time, however, there are trade offs that must be considered. For example, selecting a conformal cooling option could dramatically reduce the cycle time, but could increase costs dramatically as well. Decreasing cooling time could also result in undesired outcomes such as excessive shrinkage and warpage.
Simulation is necessary to explore different options and to find the right balance between cycle times, costs, and part quality. With the aid of simulation you can optimize the part design, mold materials, and cooling methods before the mold is built and costs are incurred.
With the goal of achieving an efficient molding process that results in shorter cycle times and
increased profitablity, simulation can be utilized to explore several different methods.
See how FADO uses Moldflow to optimize part quality and design,
cooling efficiency, and mold cycle times.
