The integrated blow molding
process guarantees the lowest production costs thanks to the systems unique features. Preforms are designed for immediate blowing allowing the highest bottle weigh reductions in the market. There is no external handling (preform handling, storage, conditioning), this results in a maximum cost reduction for logistic and manpower. There are no energy costs associated to preform cooling and subsequent reheating. The ECS platform guarantees the lower industrial maintenance costs compared to the separated injection and blowing phases. This integrated platform can operate in tropical extreme environmental conditions without expensive conditioning systems.
Energy and compressed air saving
The integration of injection and blowing process, with no need of cooling and re-heating the preforms, guarantees the lower energy costs per container produced (kW/bottle). The ECS platform features a better system efficiency thanks to the electric motor for extrusion and preform handling (no hydraulic motor). The reduction of “dead volumes” ensures lower compressed air consumption. An innovative and patented Air Recovery System (ARS) allows the recovery of high pressure air to be used for other process phases (air for service and blowing) and for others equipment.
– The ECS integrated process allows producers to make dedicated preforms in order to obtain the optimum characteristics of thickness, diameter and height for the particular size and application of the finished container. – Extremely light containers can be produced. – Low level of humidity during all phases, resulting into a higher level of crystallinity in the container which means higher mechanical and heat resistance performance. – Excellent aesthetic appearance of the container produced with no scratches or blemishes (no preforms handling). – Possibility of immediately correcting within the same machine (both in the injection and blowing phases) any defect found in the container (no risk of building large preform storage and discover later that the quality is low).
The integrated process offers the intrinsic advantage of producing clean containers. – PET resin is kept at high temperature level for the entire process, from extrusion to blowing, thus guaranteeing the industrial sterility of the finished container. – The elimination of preforms storage and handling allows the production of clean containers free of internal and external dust contamination. – A clean and virtually aseptic container allows a light chemicals treatment during sterilization processes (Aseptic filling) and lower filling temperature (Hot Fill) with the consequent savings on the overall packaging system (light weight, running cost, product integrity, etc.).
– ECS systems can produce a wide range of standard and customized, containers: lightweight bottles for standard or hot fill use, ultra clean or aseptic bottles, pasteurizable containers, warm filled bottles, wide mouth jars, round or square shaped bottles with capacities up to 30 liters, oval, asymmetric or tailor-made containers. – ECS machine are extremely versatile in processing materials with very different characteristics compared to standard PET: reground PET, recycled PET granules or flakes PEN, PLA and OPP. It can also produce containers in PET with added with AA reduction agents or reagents such as oxygen scavengers. – ECS system can also produce PET bottles added with nylon to increase CO2 barrier, and different master-batches to meet different aesthetic and functional container requirements. – The integrated system ECS (FX model) can simultaneously produce different size and/or shape containers.
