Ultra-light-weight Container Molds make use of StackTeck’s new patented technology called TRIM™ for light weighting injection molded parts. Thin Recess Injection Molding (TRIM) uses an advanced approach to thin out portions of the wall section well beyond the conventional thin wall packaging approach used for polyolefins with high melt flow indexes.
For Ultra-light-weight Container applications, we have proven the ability to achieve part weights that will make injection molding much more competitive against thermoforming, while maintaining key functional features such as the tamper evident rim on a container and high top load compression strength.
Conventional thin wall part design normally assumes a maximum L/T ratio of 300 (i.e. ratio of flow length to average wall thickness). Using TRIM, part weight savings that can be achieved using this technology are in the range of 20-40%.
The injection speed and pressure used to fill the part were normal, by thin wall packaging standards, and it is expected that thin wall molders can adopt this technology using existing injection molding machines.
