Do you have a product idea?

Let’s have a meeting and discuss your plans, years of experience help us catch design or manufacturing-related problems ahead of time. We will discuss the various aspects and options that are available. Our CAD design team will draw up your product ready for the mould to manufactured. It’s worth noting that a quality mould produces quality products repeatably. Complex shapes are CNC machined from an aluminium billet, while larger straight forward shapes can be fabricated from sheet steel. Once your moulding tool has been produced, test products will be moulded and presented for approval.

Our Series A plastic tanks come with many benefits. The acids in black waste are highly corrosive and will attack and eventually penetrate the welds of stainless steel and aluminium tanks. Not so in the case of a Tek Tank. Unlike cheaper waste tanks, our plastic material and wall thickness stops waste odours from penetrating through the plastic. So, no nasty smells fill the air.

MDPE is a food grade material and therefore it is perfect for water tanks too. Freshwater remains fresh to the taste; no plastic taint is experienced. Plastic tanks are the best solution for diesel: not only are the tanks lightweight, they are also corrosion free and offer a substantial reduction in condensation.

Rotary Moulding Service

Why Rotomoulding?

Rotational moulding is a cost-effective way to create almost any plastic product. Compared to other plastic processes, roto moulding tooling costs are significantly lower and minimum quantities are much smaller, both of which reduce the financial risks of new product development. With experience and innovative design, practically any product that is hollow can be made using this process. The process is straight-forward, yet it does take a few years to perfect.

Once designed, the rotational moulding process can produce complex shapes that are strong, lightweight, easy to replicate, and above all, cost-effective.

The Rotational Moulding Process

The mould is filled with plastic powder and rotated in two directions in an oven preheated to around 270°C. The plastic melts and sticks to the walls of the mould. With careful design and engineering, exceptional thicknesses control can be achieved. Once the plastic powder has been stabilised and cooled it can be removed from the mould. Once removed the product is cleaned and prepared, burrs are removed, and any openings and details are created.


Polyethylene is well suited to the process of roto moulding. The ability to stay stable during the prolonged heating process and its flow of excellent characteristics lead to uniform wall thickness. That said there are other polymer plastics that may be more suitable for your application.

Rotationally Moulded Polyethylene

We are manufacturing products for agricultural, horticulture, automotive and furniture to mention a few. Innovation and creativity are constant at Tek Tanks, new uses and market sectors are constantly evolving.

Our goal is to meet your product requirements, anticipate your goals and needs, and produce products that surpass your expectations.
