The manufacturing process can have a significant impact on the quality, durability, and longevity of an effluent tank. At Enduramaxx, we’re supporters of the rotational moulding technique. Here’s why, and how you may benefit:
Rotational moulding – also known as ‘rotomoulding’ - is a thermoplastic process. It begins with a mould filled with a polymer. This is steadily rotated along two axes while being heated. The result is a highly stable, uniform, seam-free tank. Alternative moulding strategies are blow moulding and thermoforming. However, these can leave behind seams. In liquid storage, seams represent a weak point, and therefore a potential hazard. With the rotational moulding strategy, the manufacturing process is continual, so there is no resulting seam.
The lack of a joining seam gives a rotationally moulded tank an even distribution of strength. This seamless construction means that even if the tank is rolled, or jolted, the pressure remains equal. Consequently, rotomoulded tanks are extremely strong. When they are manufactured from WRAS approved UV-stabilised medium density polyethylene (MDPE), the tanks can withstand even the harshest chemical and effluent environments. An additional benefit of the manufacturing technique is that these mechanical properties are entirely uniform, resulting in a completely reliable solution.
One of the true delights of rotomoulding is its design flexibility. Moulds can be CAD generated to respond to the demands of any application. This offers control over the size, shape, and even the configuration of the effluent tank. As such, rotationally moulded effluent tanks are particularly popular in locations where complex spaces are an issue, where Fluid Category 5 compliance is crucial, and where a tailored solution is demanded.
Due to its manufacturing method, rotational moulding is ideal for bulk orders. This appeals to a wide range of industries, and allows the cost to be reduced without loss of quality. WRAS approved UV-stabilised medium density polyethylene (MDPE) can be expensive to produce by other methods, so any steps that can help to reduce the cost are welcomed. When the result is a seamlessly constructed tank that boasts an impressive range of strength and durability benefits, the return on investment is even better.
There are several surprising sustainability benefits to rotational moulding. The first is that when an effluent tank is being rotomoulded, no dangerous chemicals or toxins are released. This has immediate advantages over materials such as metals or concrete. Rotational moulding creates virtually no waste, and any that is generated can simply be re-used. Indeed, recycling is at the heart of the polyethylene story, and it has come to play an important role in the circular economy of sustainability.
