Making a bespoke or prototype plastic product can be a daunting task at times, and it can be especially tough to work out which plastic manufacturing method to choose to create your plastic product. However, if you’re looking to create a one-off product or you’re still refining your design, roto moulding is often by far and away the best choice – here are just a few reasons why!
The design advantages of rotomoulding
No need for assembly
The size of the tools and the processes involved in roto moulding allows you to mould even large plastic products in a single, seamless piece. With other plastic manufacturing processes such as injection moulding, you might otherwise have to manufacture your product in several pieces, and assemble them afterwards. This can be time-consuming (not to mention more expensive!), so rotomoulding allows you to eliminate these extra fabrication costs.
Opens up multiple design possibilities with relatively complex shapes
You might not necessarily need to manufacture your product in several smaller pieces to achieve complexity in your design. Rotomoulding allows you to create your product with lots of useful design features, such as stiffening ribs and non-slip surfaces, which can increase the versatility, durability and overall utility of your product. Other possibilities include:
- Inserts, threads and needles
- Minor undercuts
- Fine surface details
(Some of our customers here at Excelsior use our roto moulding capabilities to stamp their company logo on their products, as a way of achieving greater brand recognition.)
No extra engineering required
Other plastic manufacturing processes such as injection moulding subject the plastic parts to extremely high pressures, in order to properly mould them. When you use rotomoulding on the other hand, the plastic parts involved don’t need to be engineered to withstand these high pressures, again saving you money and time when it comes to manufacturing.
The cost effective advantages of roto-moulding
Economical process, allowing low initial investment costs
Rotomoulding is at its most economical in relatively short product runs of between 1 and 100 items, which makes it a perfect process for testing out a prototype. Other plastic manufacturing processes might need product batches that run into the triple figures to become economical (depending on the product involved, of course!). This means that you can use rotomoulding to create prototypes in a cost effective, timely manner, without undue worry about high investment costs.
Design changes can be made easily
Since products created by roto moulding have no internal core, it allows changes to be easily made to an existing mould. This gives you more flexibility to refine the product over time, allowing you to get more out of your budget and saving you from having to spend the extra time and expense that other plastic manufacturing processes would normally demand.
No stress points results in high durability of completed products
Another of the major advantages of rotomoulding is that it’s capable of creating products that are highly durable. Unlike products composed of multiple pieces – which are typically weak at their joints – roto moulding manufactures products as a single, seamless part, which means they have none of these stress points. This not only makes the product more durable to wear and tear, but depending on its usage, it can also greatly increase its operational lifespan, resulting in a better-value plastic product that’s more economical to produce.
