Rotational moulding is an efficient process that is particularly beneficial for making parts with a hollow design. That might include things like cups and containers. If you want to ensure this moulding process gives you great results each time, review these protocols.
Use Minimal Parts
The first part of rotational moulding is designing products that you want to ultimately create for a customer base. If you want to see more success with creating long-lasting moulded products, then design them using very few parts.
More parts and systems can ultimately lessen the longevity of products that come out of rotational moulding because there are more opportunities for things to go wrong. This is particularly true if you're making moulded products that customers will handle a lot, such as toys and kayaks. Keep it simple to help your parts last longer.
Account for Shrinking
Shrinking often takes place regardless of what resins are used in rotational moulding. If you can properly estimate how much shrinking will happen, then you can design your moulded products effectively without having to make a bunch of adjustments.
Once you pick out a design, review its shrinking properties as best you can. You may also want to start off gradually where you only create a couple of products through rotational moulding. Then you can see what shrinking ratio is at play and create much better designs based on these shrinking characteristics.
Make Sure the Oven Is Large Enough
The reason why rotational moulding is so effective is that resin materials placed in moulds are exposed to extreme temperatures inside an oven. You want to make sure this heating structure is large enough to support the moulds you plan on heating up.
If you don't have the right setup, you can still work with a professional moulder that may have access to larger ovens to support your moulded products better. You'll just have to send over some plans of the moulds and potentially pictures so that they can set up the appropriate heating environment where the resins in moulds heat up the proper way.
Products that are hollow are typically made by a process known as rotational moulding. It can create endless things, but for the results to be amazing time and time again, you have to know how to set up this moulding process. Knowing about different moulding materials and unique attributes that come from rotational moulding can help in getting better products.
