Why Optimize Packing Pressure…

I was asked this question during a training class…

Does it really matter if we optimize the packing pressure?

My Response
Although it depends on the part geometries, an excessive packing pressure can easily add 1-3% to the overall part weight. In an commodity market, such an increase in material consumption may have a large impact on the overall profitability of the process. In many packaging markets, a 2% increase in material consumption can result in an overall profit loss.
Additional Thoughts
In today’s globally competitive market, molders should take every opportunity to improve efficiency… especially when there is no capital investment necessary. Every step in optimizing your filling, packing, cooling, recovery, and part removal results in direct increases in your overall efficiency.
