1. Rotational Moulding Introduction

Rotational Moulding Introduction A three-motor powered (tri-power) rotational-moulding or spin-casting machine Rotational Moulding (BrE moulding) involves a heated hollow mould which is filled with a charge or shot weight of material. It is then slowly rotated (usually around two perpendicular axes) causing the softened material to disperse and stick to the walls of the mould. In order to maintain [...]

2. A History of Roto Moulding

History of Rotational Plastic Moulding In 1855, R. Peters of Britain documented the first use of biaxial rotation and heat. This rotational molding process was used to create metal artillery shells and other hollow vessels. The main purpose of using rotational molding was to create consistency in wall thickness and density. In 1905 in the United States F.A. Voelke used this [...]

3. Rotational Moulding Equipment and Tooling

Equipment and Tooling Rotational moulding machines are made in a wide range of sizes. They normally consist of moulds, an oven, a cooling chamber, and mould spindles. The spindles are mounted on a rotating axis, which provides a uniform coating of the plastic inside each mould.[3] Moulds (or tooling) are either fabricated from welded sheet steel or cast. The [...]

4. Rotational Moulding Production Process

Rotational Moulding - Introduction to the Rotational Moulding Cycle Part 1 This three part video series which provides a basic introduction to the rotational moulding / rotomolding cycle. There are 3 stages, unloading/loading, heating and cooling. The first of three videos begins with the unloading/ loading phase; as shown in the video the arm moves from [...]

5. Roto Moulding Products and Design Considerations

Products Designers can select the best material for their application, including materials that meet U.S. Food and Drug Administration (FDA) requirements. Additives for weather resistance, flame retardation, or static elimination can be incorporated. Inserts, graphics, threads, handles, minor undercuts, flat surfaces without draft angles, or fine surface detail can be part of the design. Designs can also be multi-wall, either hollow or [...]

Tanks UK Product Featured on BBC’s Bang Goes The Theory

It's always it's a pleasure to see your own creation being used and broadcasted on national television. The staff at Tanks UK were very happy to produce and manufacture this 60L conical containment tank which was then featured in a demonstration on BBC's Bang Goes The Theory.

The Rotational Moulding Process Breakdown

ROTATIONAL MOULDING Rotational moulding is a process that is ideal for the moulding of hollow products. These include tanks holding liquids, flower pots, rainwater tanks, footballs, road cones, fenders, luggage trays. Polyethylene and Polypropylene are ideal polymers for this moulding process. It is particularly suitable for the manufacture of batches from 100 to 5000 units. Rotational moulding is a four [...]
