Over 40 years of experience
Dick Johanneck started Polytank, Inc. in 1972 doing custom rotomoulding. In 1977, he began
making calf hutches which became known as Poly Dome Calf Nurseries. The agricultural
products division of Polytank was later named PolyDome. Since that time, Polytank and
PolyDome have added over 200 products to their line. Polytank has dealers scattered across the
United States, Canada, and 10 foreign countries.
The rotomoulding process uses hollow metal moulds and powdered polyethylene plastic that
become liquid under high heat. The moulds with the liquid plastic inside are spun on both
vertical and horizontal axis to form a uniform thickness, or skin on the outside walls, thus the
name rotomoulding. The mould is removed from heat and allowed to cool under controlled
conditions to avoid shrinkage or warpage. The resulting polyethylene plastic product is
resistant to impact, most corrosive chemicals and temperature extremes. The slippery surface
makes it very easy to clean. Polyethylene is also environmentally friendly because it can be
recycled.
Most PolyDome products are onepiece with no seams or sharp edges. The light weight of
polyethylene makes even large units easy to lift and move.
PolyDome has their own metal fabricating shop for frames, stands, and supports used with
their agricultural products. All metal parts are powdercoated for corrosion resistance.
