What we do...
RotoStudio make small-scale rotational moulding / casting machines. This method of casting uses centrifugal force to spin a curing composite liquid within a mould 360 degrees - setting over time to create a hollow cast object. Using a fraction of the curing ingredients used in traditional moulding techniques, Rotational Moulding creates a highly detailed, lightweight and cost effective moulding process. Using up to 95% less material then standard full fill mould casting.
Rotational Moulding uses a unique plastic molding / moulding process to create seamless, stress-free, hollow one-piece component. It’s a room temperature, low-pressure manufacturing method that utilises bi-axial rotation. Typical moulded parts from rotocasting can include pottery, slip casting, resin cured objects, props and replicas, prototype parts, small toys, and hollow sculptures.

Proponents of the rotational molding /moulding process point to its low production cost and unlimited design possibilities. It’s a competitive alternative to blow molding / moulding, thermoforming, and plastic injection molding , moulding. It produces little waste since the required weight of plastic to produce the part is placed inside the mold / mould.

It produces little waste since the required weight of plastic to produce the part is placed inside the mold / mould.
In industrial rotocasting, the process begins with filling a hollow mold / mould with a quantity of powder resin (polymer). More often than not this powdered resin is polyethylene, although other compounds such as polypropylene, PVC, and nylons can also be used. The mold / mould is then heated at high temperatures in an oven and bi-axially rotated as the polymer melts and coats the inside of the mold / mould. When built at home, rotocasting is when you use a resin cast part, and place it within a Rotational Moulding Machine, spinning it around while gravity makes the mold / mould conform to the walls of the piece, making a hollowed out part.
