Persico is pleased introduce brilliant medical product solutions created by some Medical Equipment Manufacturers utilizing rotational moulding, thanks to Persico aluminium moulds. Today rotational moulding is used by the Medical Sector to create many X-Ray transparent plastics components such as side rails, headboards, footboards, bed pallets, and hospital trolleys. This economical Technology allows equipment manufacturers to produce hollow, one-piece, and seamless plastic parts, resulting in medical equipment that is not difficult clean, which seams to be a very important sanitary factor to the medical sector.
EASY ROLLER: Plastic on Wheels
People who use a wheelchair to move around must confront several difficulties and inconveniences every day. Amongst these are problems linked to the passing under control devices, which are present for instance in airports, problems caused by the formation of rust when entering places with water, such as swimming pools, or the need to leave the wheelchair to undergo a magnetic resonance. To avoid many of the traditional inconveniences resulting from the use of metal for the manufacture of wheelchairs, Torbjørn Skjæran has developed the EasyRoller wheelchair, made exclusively with plastic materials. Switch to the Rotational In 2000, EasyRoller was manufactured in its first version which included a frame achieved by welding together AB S tubes. This productive method, however, proved quite long due to the time required for welding, hence Skjæran decided to move to rotational molding that would achieve a frame with an esthetic and functional design, yet reduced manufacturing time and costs. In EasyRoller 2, which is 105 cm high and weighs only 12 kilograms, the seat, chassis, and tip-up footrest are molded in PET.
EasyRoller wheels are made with rubber, the belts with nylon, and the padding with closed-cell neoprene. Some parts such as the rims and the braking systems are manufactured by injection molding utilizing polycarbonate and AB S. The design development and realization of the prototypes for the latter components was assigned to the Norwegian design office of Eker Design that has processed solutions capable of effectively meeting the markets’ requests. The definition of forms, details, and modifications to be implemented to the chassis depending on the use of rotomolding, was carried out in a synergic collaboration by Partnerplast, amongst the most advanced rotational molders in Scandinavia, and Persico, specialized in the manufacture of rotational molds destined to projects with a high technological specifications. The two companies have positively contributed to the mold conception, with the definition of the divisions, the insertion of mobile parts, and so on, from the addition of structural reinforcements (such as kiss-off) to the selection of the most appropriate plastic materials required to meet Torbjørn Skjæran’s goals.
From the Mold to Samples
The joint collaboration of customer, designer, molder, and modeler have provided a convincing solution which combines aesthtics, ergonomics, comfort, sturdiness, duration, and performances. Given the detailed complexity, the dimensional tolerances had to ensure: the coupling with the injection molded parts, the narrow time availability, and last, but not least, the quality expected from the product, Persico manufactured the mold by milling it from the block, a technology that offers several advantages and guarantees. Once the mold had been built, the first samplings were carried out at Persico, in order to allow the assembly of all details and determine possible interventions and/or modifications to be implemented onto the product. The possibility of realizing the molded prototypes in site saved major time and costs in the global product development process. The first assembled samples have been shipped to Norway for a first presentation to the agents of the sector, and the new rotomolded version EasyRoller 2 has immediately obtained great success on the market.
