Design plays a critical role in the success of rotational moulding. The design of the part must take into account the properties of the material, the moulding process, and the desired end-use. Here are some important considerations for rotational moulding design:

• Wall thickness: The wall thickness of the part should be consistent throughout to ensure even heating and cooling during the moulding process. Varying wall thickness can cause warping and deformation.
• Draft angles: Draft angles are used to allow the part to be easily released from the mould. A draft angle of at least 1 degree per inch of wall thickness is recommended to ensure proper release.
• Ribs and gussets: Ribs and gussets can be used to reinforce the part and prevent warping. They should be designed to allow for even heating and cooling during the moulding process.
• Undercuts: Undercuts can make it difficult to release the part from the mould. They should be avoided or designed to allow for easy release.
• Mouldability: The part should be designed to be easily moulded using the rotational moulding process. This includes avoiding sharp corners or edges, designing parts with a uniform thickness, and ensuring that the part is balanced and symmetrical.
• Materials: The material used for the part must be compatible with the rotational moulding process. It should also be able to meet the desired end-use requirements, such as strength, flexibility, and durability.

Designing for rotational moulding requires careful consideration of many factors to ensure that the part can be successfully produced using this manufacturing process. A well-designed part will not only improve the quality of the final product but can also reduce manufacturing costs and increase efficiency.

Overall, rotational moulding is a versatile and cost-effective manufacturing process, suitable for a wide range of applications. However, it has some limitations that need to be reviewed when deciding if it is the right process for a particular project.

Over the past few decades, there has been a growing concern over the impact of plastic waste on the environment. Traditional plastics are non-biodegradable and can take hundreds of years to decompose. As a result, the world has seen a shift towards more eco-friendly plastic alternatives that are sustainable and biodegradable. Here are some of the latest developments in eco-friendly plastics:

Welcome to our new look web site and blog !

We wanted to better communicate to our current and potential customers the range of services we offer, the full scope of our operations and our unique position within the UK plastic’s manufacturing sector.

We will be continually developing our web site and providing much more information through our blog, so please check back with us for updates.

Our company ethos is “Quality comes as standard” and we hope this reflects in our fresh new looking web site.

Thank you

The team at Poly Products

Due to increased demand from our customers we are currently recruiting machine and finishing operatives.

The UK Rotational Moulding sector is experiencing very high demand at present, which seems to be an exception to the rule compared to other industry sectors, as we emerge from the restrictions of lockdown and recover from Covid 19.

At Poly Products we too are preparing to increase production, providing our customers with the added volumes to also meet their required customer demand.

We anticipate further growth thoughout the whole of 2021, with further recruitment, new machinery and additional factory space.

As the lockdown eases, we are moving forward confidently and looking forward to a busy year ahead!

We have expanded our vacuum forming capacity at our Sheffield manufacturing premises to meet the demand for Marqee doors and panels.

We produce standard and extra large bespoke versions.
