(in litres) Up to 30 liters Depending on individual bottle geometry: - typically 100-2,500ml with regular moulds, inner shell & outer shell system (requires additional maxi pencake at approx. >1,500ml to hold the mould closed) - up to 3,900ml with compact moulds (outer=inner shell, still usable at standard blow moulder) - up to 5,500ml with compact large moulds (only applicable at special compact large blow moulder) 12 litres 3.3 l (standard machines) - 12 l (big format machines) 30 liters Moulds supplied directly to blowing machine manufacturers Yes Yes Yes No No Do you supply retrofi t moulds for existing SBM machines? Yes Yes Yes Yes Yes For which bottle maker have you already produced moulds Sidel, KHS Corpoplast, Krones, Sipa, Kosme, ADS, Nissei, Chumpower, Terekas, 1 blow and other major machine types Big number of moulds for a a wide range of company for the industry of food & beverage, household cleaning and personal hygiene products and chemical and pharmaceutical products. No Sidel, Krones, KHS, SIG, Krupp, SMI, Siapi, Kosme, Side Bottle design service Bottle design development Yes: preform and bottle design (technical/marketing), fi nite elements analysis, 3D modelling, use of rPET SMI design, develop and virtually prototype a wide range of packaging solutions in rPET and PET, according to the customers' specifi c requirements. Thanks to an advanced CAD centre for 3D design, SMI has invested in solutions for producing rPET bottles and for supporting companies in the study and graphic realisation of a wide range of containers that are 100% recyclable, of high quality and lightweight for saving energy and material. Furthermore, SMI provides solutions for manufacturing of bottles with the utmost quality, also thanks to accurate checks made on preforms and bottles. Yes Brandbuilding, product repositioning, marketing design, packaging engineering, lightweightening of existing bottles, technical feasibility; new AWArPET analysis (Design for Recycling), etc. Specialities Quick and fl exible bottle sampling and qualifi cation in Röders laboratory with certifi ed equipment. New: Diamond milling technology and Röders Racecut system will lead to shorter lead times for our customers. Light weighting, low pressure, complete PET line optimisation, carbon dioxide calculator, global key account certifi ed laboratory, … The moulds are manufactured using a special aluminium alloy. SMI relies on a special laboratory for the production of moulds and mechanical components, equipped with an FMS line consisting of 12 CNC machining centres: highly automated machines, running 7 days/week round the clock, even operator-less, according to pre-set production programmes (CAM). The 12 machining centres can achieve an output of more than 15,000 moulds/year; they are equipped with linear motors with a speed rate up to 80m/min and mandrels achieving a speed rate of 30,000 rounds/min. As a result, top-level quality standards are constantly provided. Double cavity concept, low pressure base moulds, stainless steel moulds Wide mouth, large sizes (up to 30 liters), asymmetrical, Nitrogen hot fi ll, containers with handles, HDPE to PET conversions, pharma & cosmetics Other Solutions for compatibility of moulds between different machine types, new Röders RMC-system for quick mould change to reduce changeover times and cut mould costs. The “ReduxAir” system allows to carry out stretch-blow moulding operations at lower pressures than usual. By an innovative design and specifi c technical solutions this system allows for the air in between the bottle's outer walls and the mould's surface to be more quickly released; thus, the PET bottle manufacturing process can be carried out with compressed air pressure at 15-20 bars (such a value depends on the preform and bottle features and on the stretch-blowmoulding process conditions). The great advantage the ReduxAir's user can benefi t from in terms of lower power consumption of the compressor requires a few design limitations in the bottle's shape and features.
