The result is, accord- ing to Aoki, twofold: firstly, there is a significant energy saving and secondly a cost reduction in each container produced. Product range and applications The SBIII series is a comprehensive range with customers able to choose from injection capacity – pump motor – heater (hot runner) – hydraulic oil volume – to ensure they select the most appropriate machine size and machine weight. Other options include the number of cavi- ties – neck diameter – body diameter – height – and output. Aoki single step systems cater for the typical single step applications such as for “high cycle moulding, for clean room and small narrow neck containers, lightweight wide mouth containers, mass production of small narrow neck contain- ers, small containers, multi purpose containers, and also special purpose moulding ranging in capacity from the tiny 5ml container up to 90l containers.” Conscious of increasing environmental con- cerns, Aoki offers Direct Heatcon machines for recycled PET (Aoki series) - with an agitator/ hopper dryer in combination with the vacuum-type barrel venting systems “removing moisture con- tent and impurities from the resin.”Understanding Aoki’s bottle to bottle recycle concept, more and more different applications are emerging from around the world, from 100% reground flake PET for non-food containers to blending clean recycled flakes with virgin PET material for food quality bottles. Key figures All Aoki single step machines and the genuine moulds are produced solely in Japan. The company has their machines running in 77 countries around the world. www.aoki.co.jp Hidenaga Nakagawa, Director Aoki Technical Laboratories
