There is not a product on the shelf for every situation. When you need a specialised plastic product that was built to last, choices can seem limited. But unlike other plastic manufacturing processes, custom rotational plastic moulding is very cost-effective, even for once-off orders. It’s not just due to the services and proficiency of manufacturers such as Calcamite. Much of this value has to do with the rotational moulding process itself:
1. Rotational moulding covers a large variety of sizes
Rotational moulding equipment is formidable, taking up a lot of space. This makes it possible to craft very large tanks that can hold thousands of litres. But the size of the object is down to the mould, which can be much smaller than the oven space. Chairs, dustbins, even toys can be manufactured in this fashion.
2. Products made through rotational moulding are strong
Products created with rotational moulding benefit from high tensile strength. You can learn more about the specifics in our blog post Why tanks made through rotational moulding are superior: the combinations of plastics used, the steady coating process caused by the rotation, and the fact that the plastic is baked all help to create very strong objects that will last for decades.
3. Rotational moulding is faster and cheaper
One significant question around creating a plastic product is about scale. For some plastic manufacturing methods to be viable, a large number of items need to be produced. But rotational moulding is already cost-effective at low runs, even single objects. This is due to a number of reasons, including fewer complexities around mould design and machining.
4. Better scale as demand grows
Rotational plastic moulding is a cost-effective choice even on very low volumes. But it also can scale comfortably to cover larger orders. Since the process limits moulds to two parts, replacements are easier and less costly, and moulds tend to wear more slowly. This helps increase the yield per mould, working it for longer.
