Injection stretch-blow molding machines (ISBM) model ECS SP 80, 50 and the new ECS SP 25 are designed for the production of containers in smaller lots than SIPA’s existing ECS FX single-stage units. They have features that enable quick change-overs between different product configurations, and they are also characterized by their compact layouts and high energy efficiency. Moreover, the handling of the preforms (always kept from the neck) allows for neck and container shoulder design not feasible with two-step technology.
The ECS SPs are ideal for the production of bottles with volumes as small as 20, 30 and 50 mL, typically used for such products as pharmaceuticals and also miniature shampoos and lotions used by hotels.
The SP models use hydraulics when large forces are required (e.g. to apply clamping tonnage) and servo-electric drives for fast movements (e.g. open/closing of the blowing unit). This combination is very energy efficient, helping the machines achieve a carbon footprint smaller than key competition. A key feature of the ECS SP 80 and SP 25 (not really true for SP50 because it's a 3 station concept) is that they both accept molds originally designed to run on equipment from major competitors.
