When you need custom made plastic agricultural tanks, the real win isn’t just capacity—it’s getting a bespoke, leak-resistant tank that drops into your fertigation room, sprayer rig or yard setup without compromises. Rotational moulding is built for that kind of practical engineering, and it’s exactly what ABC Rotomoldeo specialises in.

In this context, the agricultural sector represents an area of great importance to us, where our technological solutions provide significant value.

Why rotomoulding is ideal for agriculture tanks

Rotomoulding produces one-piece hollow parts with consistent performance across the whole wall—perfect for liquids, dosing systems and chemical products.

What that means on the farm

• Fewer leak points: no welded seams across the body.

• Design freedom: fittings, manways, ribs, mounting faces—where you actually need them.

• Long service life outdoors: UV-stabilised polymers + robust wall thickness.

• Short runs are viable: you can build to spec, not just “closest catalogue model”.

Typical rotomoulding workflow

• Design + 3D model based on your footprint, connections and constraints

• Tooling that matches the final geometry

• Moulding (heat + bi-axial rotation)

• Finishing (threads, flanges, inserts, markings, QA)

Xometry highlights a key outcome of the process: producing parts with “uniform wall thicknesses, and excellent stability.

Core applications: Water storage, dosing and fertigation

Most agriculture projects fall into three overlapping needs:

• Water storage or dosing 

• Fertilizer tanks (liquid fertilizer) for nutrient solutions and feeding schedules

• Chemical handling (within material compatibility limits)

Benefits of rotomolded agriculture tanks

The adoption of rotomolding techniques for the manufacture of agricultural equipment offers multiple advantages. 

• The ability to produce large and complex parts in a single piece, without the need for assembly
• Significantly reduces production costs and increases the durability of the components.
• The design flexibility allows the creation of custom solutions that perfectly meet the needs of farmers, contributing to greater accuracy and efficiency in agricultural operations, including products such as plastic fertilizer tanks.

Build the tank around the process, not just the volume

A good specification starts with how the liquid behaves in real use:

• Does it need recirculation to prevent settling?

• Will you inject via Venturi, dosing pump, or central fertigation controller?

• Do you need a calibrated level scale for dosing accuracy?

• Can the system fully drain for cleaning and changeovers?

Beyond tanks: seed boxes, “hoopers”, and fertiliser components

Rotomoulding isn’t just for storage. If you want consistency across your farm machinery parts, you can spec multiple components under the same manufacturing logic:

• agriculture tanks (sprayer tanks, nurse tanks, mixing tanks)

• custom made plastic seed boxes (durable, lightweight, corrosion-proof)

• custom made plastic hoopers (often referred to as hoppers—feeders/tolvas)

• custom made plastic fertilizants (bespoke plastic components for fertiliser handling systems)

This approach simplifies maintenance (fittings, seals, spare parts), and it lets you standardise on wall thickness, UV packages and mounting interfaces.
