Norwalk Hydra-Strip™ Tank Mold equipment is custom built to
manufacture tanks which will meet local specifications. Prior to
construction of any mold equipment, Norwalk recommends that you
discuss tank requirements with your local regulatory agency. After
such discussion, our engineers will provide you with drawings or
other data necessary to get approval. Through this means, you can
be assured of a locally accepted product, manufactured from a mold
of highest quality with a minimum in labor costs.

TWO PIECE TANKS
The most popular and versatile by far. Used throughout
the U.S. and Canada. Permits incorporation of cast-in-tees,
baffles, and compartment walls as an integral part of
and labor saving feature of this particular design. This
tank consists of two equal halves joined at the center. |
|
|
ONE PIECE TANKS
Some states require that the joint line of a septic tank
be above the liquid level. The one piece tank meets this
requirement. The tank consists of a box (tank) and cover. |
| Norwalk’s Hydra-Strip™
Septic Tank Molds offer the very latest in automated septic
tank production. Each mold incorporates the best of Norwalk’s
many years of knowledge and experience both as a precaster
and as a manufacturer of mold equipment for the precast
industry. |

operating mechanism. A hydraulic cylinder rotates two
axles which in turn rotate cams on each end of the two
axles. The cams then raise four pistons which eject the
tank from the mold core. The hydraulic operation combined
with the fact that all parts are linked mechanically,
insures smooth, jam free, stripping of the mold. |
