Septic Tank Molds
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.

NORWALK MANUFACTURES MOLDS FOR . . .
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.

Photo at left shows Hydra-Strip™ 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.
