Rotational Moulding is a process for manufacturing hollow plastic products and has a relatively inexpensive path to market compared with other plastic manufacturing processes. Products made using rotational moulding techniques are renowned for their strength and durability. Because the moulds used in rotational moulding are comparatively cheap, both small and large production runs prove cost-effective.
Step 1: Plastic in powder form is poured into a mould
Step 2: The mould is heated under rotation, causing the plastic powder to melt and form a uniform layer on the inside of the mould
Step 3: The mould is cooled as it continues to rotate so that the plastic solidifies
Step 4: Once fully solidified, the new plastic product is removed from the mould.
Inserts, undercuts, and special tooling and moulding techniques can be used to create different desired effects or reduce the need for time-consuming finishing processes. Read more about the process, or talk to us about how we can achieve this on your next plastic product.
Polyethylene is most commonly used in rotomoulding, however, PP, PVC, and PLA are all examples of other materials that can be rotomoulded. PE’s for rotational moulding come in various densities which will have an effect on strength, stiffness, chemical resistance and impact vulnerability. The polymers that we use most commonly have been proven through years of robust use and there are many specialty polymers to assist you in fulfilling any special requirements such as brand colours, flame resistance, stability in sea water etc. Our team will recommend the most suitable product if you are unsure of the benefits of particular materials and grades.
Caring for the people who use our product and make our product is important, and so is caring for our environment. Rotationally moulded products are normally always recyclable. We take that a step further and our goal is to receive back 100% of Gyro products removed from service, recycle and reuse 100% of the raw material collected.
