The Assmann  Difference 

We at Assmann Corporation are constantly finding ways to increase efficiency in our process. But we’ll never abandon successful methods for any cost-cutting measure that would compromise the quality we’re known for. That means we’ll always provide a tank you can trust, in a timeframe that works for your needs.

No Cutting Corners

Part of what makes our process so unique is that we do not “shield” the outside of our tank molds. In a competitive marketplace it has become a common practice to wrap and weld layers of sheet metal (shielding) around the outside of the mold to reduce heat transfer.

Cross-Linking to a High Degree

We have separate chambers using only very high volume air movement to assure a gradual cooling of the mold and the part inside. This allows the cross-linking process still taking place upon exiting the oven chamber to complete throughout the entire tank wall.

Rotational Molding

Our unique and efficient large ovens, which rotate end-over-end, receive convection heat from an adjacent stationary furnace. The oven shape and foil design create optimum airflow and uniform heat to set the first stage for the highest quality parts possible.
