In September 2017, Association of Rotational Molders or ARM, held an exposition at the Rotoplas in Chicago, where PSI Brand had the opportunity to be part of history by using the world’s smallest operating rotational moulder to demonstrate the moulding procedure of our newly launched INMOULD X-Treme graphic system!

The Rotoplas event is arranged by ARM, a worldwide trade association currently representing member companies in 58 different countries, including manufacturers of rotationally molded plastic products, suppliers to the industry, designers, and professionals. It provides a platform for industry communications, and is considered to be the authoritative source for information on rotational moulding globally.

Due to the current global COVID-19 pandemic, ARM’s next Rotoplas exposition has been rescheduled to September 2021. For more information, take a look at their blog.

The 2017 Rotoplas exposition featured an adapted miniature rotisserie oven that had been customised into a fully functional, dual axis rotational moulding oven, earning it the title of the ‘world’s smallest operating rotational moulder’. Designed as a small rotational molding machine for demo graphics at exhibitions, the unique multi-axis moulder has become a popular attraction at global moulding events.

At PSI Brand, we jumped at the opportunity to get in on the action with a mould in graphics demonstration at Rotoplas by using the famous miniature oven to demonstrate the moulding process of our brand new INMOULD X-Treme graphic system. This new permanent branding process features transparent backing and a high level of resistance to the elements, UV and abrasion, as well as our classic ‘peel and stick’ application.

The oven utilises a high temperature glass mould and polyethylene in its moulding process, with heat generated by two radiant electric bars at the top of the machine. Around four minutes after the machine time is set and the heating begins, the plastic begins to stick, and forms molten clear at the edges. At eight minutes in, most of the plastic has melted and formed against the glass – being natural medium density polyethylene, or MDPE, the powder becomes transparent as it melts.

As soon as the moulding process is complete, the machine begins to cool. Once cool, the product is quick to demould, and the finish is flawless.

The polyethylene moulding process as seen through a high temperature glass mould gives us a rare opportunity to witness exactly how rotomoulding works, and how a graphic moulds to polyethylene. To see a video of the world’s smallest rotational moulder in action demonstrating none other than PSI Brand’s INMOULD X-Treme graphic system, see the video.
While this roto-oven provides a unique opportunity to promote and display the rotomoulding process, we recommend the RotoRocket desktop oven available from 493K for staff training and induction sessions, customer demonstrations, problem solving, powder flow testing, experimentation etc.
