Rotomoulding for competiveness
Predecessor to the Mi chair, the Vortex chair is fabricated using 100% carbon fiber. The purpose of using such an extremely high performance material was to optimize the strength and lightness characteristics, while creating an object with an extremely thin cross section. The shape is driven by ergonomics and engineered structural efficiency. The Vortex chair is beautiful and functional, but also expensive - $12000.00 USD. The cost is driven by the material, but also the process – over 80 hours of manual labor goes into each chair. “I love the Vortex chair, - says Giovanni Pagnotta, the chair’s designer – the combination of material and form render it sublime...but I wanted an affordable alternative as well - and so we have the Mi chair. Rotomolding offered the best compromise on all levels: the tooling is much more affordable when compared to injection molding, and the labor per part is greatly reduced - requiring very little post molding detailing. I chose Persico because they are the best - the end product is directly related to the quality of the tooling. Persico was extremely professional throughout the entire process, and the tool for the Mi chair is a work of art in its own right. The chair is currently fabricated in the United States by Remcon Plastics (which has offered a great support too) because it was strategically the right decision at the time, but we are investigating fabrication in Europe for the European market as well.”
As though it were a spinning–top...
Among the more original creations from Magis, there is the rotating Spun chair which is characterised by a spinning-top style design created by Thomas Heatherwick. This individual shape was made out of a single polyethylene profile rotated 360° using
rotational moulding. Shape and functionality allow for a comfortable and informal chair by playing with the rotating action, designed by cleverly balancing the centripetal and centrifugal force (a concave chair and base which is bigger in diameter than the actual seat) so that you can never be tipped out. The excellent resistance and high insulating properties of polyethylene mean that it is suitable for outdoor use. Eugenio Perazza, president and founder of Magis said “It has been about 20 years since Persico begin manufactuting moulds for Magis. Persico is our only supplier for rotational moulds; I think Persico over so many years of collaboration has built about one hundred molds for us. In Persico we find high technical competence and know-how. They always know how to assist and advise us in the development of our design projects.”
A slow regeneration
The Regeneration project, “a regeneration of ourselves through the imitation of life’s slow processes”, is represented by Snail spirals, which in the language of contemporary art conveys three metaphors: hearing (the “form” of the spiral is reminiscent of the human ear), living (this lovely little animal carries its home on its back), and the graphic symbol @ depicting web-based communications. “The Regeneration project,” said Renzo Nucara, member and co-founder, together with Marco Veronese, Alex Angi, Carlo Rizzetti, Kicco, and William Sweetlove of the Cracking Art Group embodies yet another important value – the snails are made of plastic. In particular, for our installations, we use animals in objects that are moulded using the rotational technique, as our plan is to re-evaluate plastic as an ‘artistic medium’. To make the moulds for the individual animals we took advantage of the collaboration with the Persico company because it has good technical skills and a particular sensitivity which makes it possible to transform an idea into an accurate model”. After starting off in Milan in November 2009, the project then travelled to Treviso, Rimini, Paris, Rome, Miami, and is currently heading toward new cities before returning to Milan for Expo 2015.
With great personality
Alberto, the ironic clotheshorse, was designed by Fabrica for Casamania and is made out of massdyed polyethylene using rotational moulding. It is just great for use in the garden or on the terrace as it can withstand both light and water. Alberto can also be used individually, as a decorative object or a coat-rack, and it comes in the following colours: orange, light-blue, white, brown and green. What’s more, it can be fixed directly to the ground using a square metal base. Based openly on the requirements of the Panton Chair, Him & Her, made to a design by Fabio Novembre, have evolved from that hermaphrodite model of perfection into the harmony of the two sexes. They adopt bodies sculptured like nude models of seduction, but they feel no shame. The two chairs, modelled and shaped on the figure of a man and a woman, are available in black and white. “In both cases – said Loris Tessaro, the Research & Development Manager at Casamania - the decision to use rotational technology is representative of the product itself. Only with this technology could Him&Her and Alberto be produced. To make them we contacted Persico: a company that is synonymous with quality and professionalism”.
In soft lines
Recently awarded the BOY (Best Of Year) Award 2010, in the Outdoor Furniture category, the Surf collection, designed by Karim Rashid for Vondom, has a fluid line and numerous performances that are achievable thanks to rotational moulding. Made out of 100% recyclable material, it comes in a wide range of colours and finishes, it can withstand critical temperatures, outdoor conditions and the shape was based on a design that is in keeping with both current trends within the industry and today’s functional and decorative requirements. To make it, Vondom turned to Persico, having found it to be a competent and reliable partner.
