This guide will focus on the latter and highlight best practices to reduce areas of localized stress at common areas of concern, such as corners and edges as well as reinforcing and assembly features . RIBS Ribs are thin, reinforcing features that can add structure and strength to a part . GUSSETS Gussets are support features that reinforce the connection between vertical features (such as walls or bosses) and the part’s floor .

They reinforce packaging integrity by maintaining a film’s sealing properties, avoiding delamination of the film structure, and maintaining transparency.

This demonstrates whether there is any residual dead zone material that continues to enter the melt stream. With new innovative technologies, Avient continues to develop TPEs that bond to a variety of substrates. If the heaters are on continuously, there is not enough heat being produced from shear.
