Experimental-Based Optimization of Injection Molding Process Parameters for Short Product Cycle Time

Table 7

Comparison of the optimization simulation results to the experimental validation results for the optimum cycle time, warpage, and volumetric shrinkage (the experimental validation was conducted based on the optimized process parameters, and the resulting cycle time, warpage, and volumetric shrinkage are compared to optimum simulation results, as shown in the table).

	Optimized cycle time	Warpage	Vol. shrinkage
Optimization results from the simulation (sample 14 in Table 6)	29.06	4.36	3.48
Experimental validation results (inj. molding run for sample 14 parameters in Table 6)	31.0	4.5	3.2
Difference	6.7%	3.2%	8.0%
