ROTASIN - the expert for rotated plastic products

Everything we think about and do revolves around plastic – and for more than 20 years our key focus has also been the demands and wishes of our customers. We act as your very own producer of premium-quality, advanced plastic parts made through rotational moulding. From smart rotated plastic housings for use in cars and domestic gardens, to simple (or sometimes highly complex) tanks and water systems, plus housings for a whole host of applications and containers. Our underlying motivation is to meet Made in Germany standards and thus allow you to rest assured that all safety requirements have been met in production, that all materials are absolutely flawless and that all QA procedures are certified and implemented as required.

We see ourselves as a partner to your enterprise at all stages of the value chain. So we provide you with support when planning and designing original parts, match product requirements to the ideal production process, ensure all required quality standards are adhered to throughout, and deliver solutions that are matched to your individual needs when shipping your products to their destination.

Manufacture of rotated plastic products

On-Demand – Just-in-time

We produce your parts on four carousel rotational moulding machines from RotoSpeed and Polivinil. While the maximum tool size depends on the measurements and dimensions of the rotational mould, quantities and production times depend on your requirements. Our largest rotational moulding machine offers an oven diagonal of four metres.

The tool for plastic rotation

New or used rotational moulding tools

We help you design and produce tools for rotational moulding by working in close collaboration with highly qualified and experienced toolmakers. If you’d like us to analyse and produce a tool for you, please send us a 3D drawing of the tool you need – ideally in STEP, IGS or PDF format.

We can of course also work with tools that have already been used in a different production cycle. Click here for more information on the tools used in rotational moulding:

Plastics for rotational sintering

Choosing the right plastic for rotated products

Let your imagination run wild! Most products can be rotated in any imaginable colours. It’s even now possible to incorporate wood granules and metal pigments. Rotational moulding can involve polyethylene (PE), polypropylene (PP), recyclate or effect mixtures. At ROTASIN, we source all our plastics from European providers.
