Thank you for your reply.
yes I am looking at Mold PM based on cycle (complexity of molds) and steps to take during PM (what will be the best check list for diferent type of molds)
In a lean environment with time pressure (Automotive) we need to establish an efficient PM.
Weld Lines occurs due to temperature difreences between two material fronts.
The material (melt) flows into cavity in a FOUNTAIN FLOW.
If an obstacle (any geometry futures in the cavity which obstructs the flow) will create two material flows (these two material flows will have a diferent...
First Question:
Are you molding Nylon ?
Note
You may want to check the reverse tapper nozzle design (it will help with drool and stringing)
Also you may want to develop your Temperature of Melt vs Viscosity curve for the most otimum Fill Time and Melt Temperature
You may want to check the...
