APRIL CHALLENGE INSTRUCTIONS:
SCENARIO – For this challenge, you are molding a square cover which is 6.500” x 6.500” plus or minus 0.005″. The plastic you are using is Polystyrene on a 300 ton machine. Your part has flash, burnmarks, and is out of dimension. The standard (quoted) cycle time for this job is 14 seconds. The part tolerance for this job is ±.005.
The mold maker for this part made a mistake. The cavity length was made 0.005″ oversized. In the molding plant, the molder knew how to set the molding conditions that compensated for the error. He was able to mold this part to within 6.500″ and 6.505″. Can you?
CHALLENGE – You must solve the part problems and then improve the cycle. Try to get the highest efficiency score you can. But remember, you do not get a score unless all the part problems are solved.
BONUS – A 2% bonus will be added to your score if the melt temperature is within 2 degrees fahrenheit of the front zone barrel temperature.
