Frequently Asked Questions

How are the Tanks Made?

AMP Tanks' tanks are created by a process callled rotomoulding. Rotomoulding offers relatively low tooling costs, economical short runs and ability to cope with large moulds. It is ideally suited to new product development and prototype work can be carried out without vast expense. The process of rotomoulding is essentially very simple and can be broken down into four key stages.

The Process Explained

1. Loading
The metal mould is filled with a predetermined quantity of polymer powder, closed, clamped and then passed into an oven chamber.

2. Heating
The mould is heated externally to a high temperature and rotated around. As the powder inside heats up, it begins to melt and adhere to the inner surface of the mould.
3. Cooling
In the cooling chamber air is directed at the mould and in some cases water jets are used. When the plastic inside the mould has become solid, the mould can be removed from the chamber.

4.Unloading
The plastic component is then removed from the mould and allowed to finish the cooling process unrestricted by the mould.


Why Choose Rotational Moulding?


An ever-increasing awareness of the rotational moulding process has led designers to choose this process for some quite complex parts. Relative to blow moulding, rotational moulding permits much more complex, asymmetrical shapes. Wall thickness distribution is more uniform with rotomoulding and part size can go well beyond anything which is possible with blow moulding. Relative to injection moulding, rotational moulding has major advantages of low mould cost and the ability to produce complex hollow articles.

Advantages:

01Tooling costs are relatively low when compared to other processes. This is mainly due to the fact that rotational moulding is a low pressure process meaning high strength moulds are not needed.

02Moulds which differ greatly in shape and size can be can be run simultaneously on the same equipment.

03Wall thickness uniformity is good when compared to blow moulding or thermoforming.

04Finished parts can be virtually stress free if designed carefully.

05The process is extremely versatile. Parts can be manufactured with inserts moulded in and surface textures and effects reproduced with relative ease.

06Using automated oil heated Leonardo machines, Rototek can now deliver large production runs economically having virtually eliminated the labour content.
