TRIM™ Pails

TRIM™ Pails

Leveraging StackTeck’s technology for sustainable solutions has allowed us to incorporate our TRIM™ technology when molding pails, reducing the weight of an industry standard 5-gallon pail by 75 grams.

 

TRIM™ Pail Mold running at 13 seconds cycle time

 

StackTeck began this pail mold development by benchmarking several different 5-gallon pail molds with thick rim features that presented a cooling challenge.  Most of these reference parts typically run in the range of 16-18 seconds. TRIM™ involves molding ultra-thin panels with flow leaders that assist with part filling and maintain part strength. This approach allows StackTeck to offer part weight savings that support a sustainable approach for injection molded pails in the market.

The TRIM™ panels on this pail have been reduced to 0.060 inches.

 

STANDARD 5 GALLON PAIL – 940 grams

090” wall thickness

 

TRIM 5 GALLON PAIL – 865 grams

8% Weight Savings!

As Low As 0.060” wall thickness

 

 

 

 

 

 

 

The optimized TRIM™ pails are 8% lighter than a benchmarked industry standard 5-gallon pail, while meeting UN standards 7.4 (drop test) and 7.5 (compression test). With filling analysis software, we were able to optimize the pail for injection       pressure and tonnage increase.

Mechanical Testing UN Pail Standards 7.4 (drop test) and 7.5 (stacking/compression test)

 

Structural filling analysis was done to ensure top load strength and survival of drop tests. After running simulations, it was identified that there is a big reduction in the strength and performance of the part when thinned out portions closer to the bottom corner of the pail were done. The designe evolved to remove the TRIM patterns from the lower portion of the part while maintaining the light weight in the remaining areas of the pail which did not affect structural strength.
