Rotational moulding is a unique production method used to create hollow plastic products. This technique is particularly suitable due to its ability to produce large, durable objects with uniform wall thickness and complex shapes. In this article, we would like to tell you more about the steps involved in the rotational moulding process.

The rotational moulding process

The future of rotational moulding will be driven by technological advancements and the growing demand for sustainable production methods. In this blog, we look at the developments, recent trends, and innovations within the industry.

The future of rotational moulding

The importance of transparent and accurate information about every phase of our production process is increasingly significant due to recycling opportunities and quality control. From raw materials and assembly to final product properties and transport, every detail is meticulously recorded and traceable through our advanced Critical to Quality (CTQ) system.

Comprehensive quality management and traceability at Pentas

At Pentas, we take pride in the wide range of products we can manufacture using our rotational moulding process. Rotational moulding is an extremely versatile technique used in numerous markets and countries. Our products range in weight from 500 grams to 100 kilograms, and the applications are just as diverse. Whether it’s urinals for events, fuel tanks for agricultural machinery, buoys at sea, or water tanks in campers – our production currently exceeds a thousand unique products.

More than a thousand products: The versatility of rotational moulding

Over four years ago, on January 22, 2020, Pentas took a significant step towards sustainability. With the support of the Almelose aldermen Maathuis and Van Mierlo, the installation of 1,660 solar panels on the roof of our factory was initiated. In this article, we reflect on the impact of four years of solar energy at Pentas.

Solar Panels at Pentas: Four Years Later

At Pentas, we use various rotational moulding machines to meet the diverse needs of our customers. Our facility is equipped with 10 carousel machines and 1 advanced Rock and Roll machine, together providing a wide range of production capabilities.

Which rotational moulding machines do we have?

Rotational moulding is a popular choice for a wide range of applications. In this article, we discuss the various materials used in rotational moulding, their properties, and the factors influencing the choice of material for specific applications.

Materials for Rotational Moulding

The offshore industry operates in some of the most challenging and unpredictable environments in the world. Whether it’s drilling rigs, wind farms, oil platforms, or maritime installations, the materials and products used in this sector must be exceptionally durable, strong, and reliable. Pentas offers rotational moulding as a versatile and robust manufacturing technique that perfectly meets the demanding needs of the offshore market.

Within the available rotational moulding materials, polyethylene (PE) is the most common. There are significant differences within this category, but generally, they can be categorized into Linear Polyethylene (LPE or LLDPE) and Crosslink Polyethylene (XLPE). Each of these prominent materials has unique properties, which are discussed further in this article.

Obtaining a TÜV certification for plastic fuel tanks is a process that assesses both the quality of the end product and the manufacturing process itself. TÜV is an internationally recognized certification body based in Berlin. They test and evaluate the safety and quality of products, systems, and services.

TÜV certification for plastic fuel tanks

Rotational moulding is known as an advanced manufacturing process in which plastic powder is placed inside a mould. This mould is heated while rotating around two perpendicular axes. Due to this unique rotation, the plastic powder melts and evenly coats the inside of the mould. This results in a hollow product with a lot of design freedom regarding shapes and throughputs, something that is often difficult to achieve with other methods.

The art of mould making

For half a century, Pentas has been at the forefront of innovation, manufacturing the most complex products through rotational molding for a wide range of customers. Our extensive experience has created a treasure trove of history, ranging from producing surfboards to realizing an award-winning plastic tank for CLAAS. We are eager to share more about all our highlights in 50 years of Pentas.

Our history at a glance

The plastics industry is facing significant changes, as the assumption of using virgin materials for manufacturing products is shifting. This change is driven by increasing environmental awareness and the need to reduce the consumption of new raw materials. There is an urgent demand for smart ways to reuse and recycle plastic waste, with reference to the Waste Framework Directive (WFD) within European regulations.
