Rotational Moulding

Endless Possibilities
Adaptability

Entrust us with your unique vision for custom made plastic. Our designers and engineers know the potential for rotational moulding, particularly in applications that require hollow parts or complex shapes. Major advances in plastics and roto moulding technologies mean rotational moulding companies like us can produce even more versatile and valuable custom plastic pieces.

A big factor in the growth of rotational moulded products is in its adaptability from short runs to large scale production. Such is the scope of the process that it can make custom plastic parts as small as a ping-pong ball, weighing just a few grams, or as large as a 10,000-litre tank, weighing almost 300 kilograms.

Unsurpassed Moulding Technique and Technology

Rotational moulding makes it possible to manufacture sophisticated custom plastic components. These custom plastic components can be made in complex shapes and different sizes. In fact, some of these parts would be impossible to produce through any other moulding process.At Kiel Industries we have revolutionised rotational moulding in Melbourne. Since we first established ourselves in 1989, our Australian owned and operated company has continued to push the boundaries of custom mouldings.For the past 25 years, we have provided our clients with a wide array of rotational moulded products to elevate their business. With our thorough knowledge and expertise in custom moulding, we have been able to become one of the most trusted rotational moulding companies in Australia.What makes us stand out from other rotomolding companies is that we can bring your ideas to life. Our team of professional rotomoulding products specialists go beyond making custom plastic parts. We offer complete custom plastic moulding solutions to suit your needs. No job is too complex, niche or small for us to utilise our robust roto moulders.

Processes Overview

Versatile

We have been highly regarded for providing innovative rotational moulding in Melbourne. Our process can be adapted to the customer’s needs and the designer’s imagination. Combined with our in house steel fabrication, we can also add internal steel frame structures to your design to strengthen your custom plastic components for even the toughest of conditions. The potential for rotational moulded products is vast.

Advantages

Rotational mouldings are used because it doesn’t require weld lines or joints, the end product is essentially stress-free. Rotomoulding is inexpensive, the manufacturing is relatively quick, and economic short production runs are viable. There are no wasted materials, multi-layer products can be made, and different product types can be produced on a single machine simultaneously.

Simple

The principal of rotomoulding is simple: a hollow, shell-like mould is filled with a certain amount of granulated plastic powder (called the shot weight). The mould is rotated about two axes inside an oven where the plastic powder melts and coats the inside of the mould to form the plastic part. The rotation continues during the cooling phase so that the plastic pieces retain the desired shape as it solidifies. When the plastic has become rigid, the rotation is stopped to allow the removal of the plastic product from the mould.

Processes

The mould is rotated or around two principal axes at low speeds. It is heated so that the plastic enclosed in the mould forms against the mould surface. The rotation continues during the cooling phase so that the plastic retains its desired shape as it solidifies. When the plastic has become rigid, the rotation is stopped to allow the removal of the plastic product from the mould.
