Rubberized Sump Basin Demolition Comparison

AK Industries wanted to improve the flexibility and crack resistance of their sump pit and sewage basins. EntechTPE provided turn-key solution that included the following:

  • Formulation of a 90% recycled copp and 10% recycled TPO from automotive headliners
  • Deep drawing injection molding capabilities on a Krauss Maffei 1200 ton

These parts need to hold up to cold storage, shipping, in-field handling and installation. To demonstrate the significant improvement of the new material and injection parts, EntechTPE performed a drop test and compression test as shown in the above video.

While the new parts demonstrated the desired flexibility and crack resistance, the original parts didn’t fair so well as shown here:
