New SIPA single-stage PET bottle production system: ECS SP50 and ECS SP80

The latest addition to SIPA’s range of single-stage PET injection-stretch-blow molding (ISBM) systems has been showcased at last NPE show in Orlando, less than 2 months ago. The machine was equipped with six-cavity molds, also built by SIPA in its tool shop, one of the largest in the PET mould making industry.

The ECS SP 80, together with the smaller ECS SP 50, are both designed for production of containers in smaller lots than SIPA’s existing ECS HS and FX single-stage units. They have features that enable quick change-overs between different product configurations, and they are also characterized by their compact lay-outs and high energy efficiency.
The machines are ideal for companies who want to differentiate themselves from the competition with different designs, while still achieving reasonably high output rates. Customers will also be able to take advantage of SIPA’s technical support in new package product development.

The introduction of the two models follows the acquisition last November by SIPA of the PET ISBM equipment business of another Italian company, Automa. SIPA now has an even stronger position than before in the market for equipment producing specialty products for food, beverage and non-beverage sectors, such as containers for pharmaceuticals, cosmetics, personal and home care products, and spirits.
SIPA has been producing larger ECS single-stage ISBM machines for close to 30 years. With outputs of over 30,000 bottles/hr, these machines are at producers of beverage bottles (water, soft drinks, juices, etc., including hot- fill types), as well as major producers of detergent, food and personal care products, in particular in the North American and South East Asian markets where this level of productivity is required.

With the addition of the smaller machines to its range, the company is now in a stronger position to cater for customers who need to change molds frequently on equipment well adapted to producing bottles with widely differing dimensions. Customers will also be able to take advantage of SIPA’s global service, provided by 17 assistance centers that it operates in countries all around the world.

The ECS SP 50 and 80 are ideal for production of bottles with volumes as small as 20, 30 and 50 mL, typically used for such products as pharmaceuticals and also shampoos and lotions used by hotels. For production of bottles of this size, the machine accepts molds with as many as 16 cavities, enabling outputs of up to 6000 bottles/hr. It can also mold larger bottles, up to 5 or 6 L, using two- cavity molds.
The ECS SP 80 and 50 are both designed for high speed production, using hydraulics when large forces are required and servo electric drives for fast movements. This combination is very energy efficient, helping the machines achieve a carbon footprint smaller than key competition. The ECS SP 80 can reach energy consumption as low as 20 kWh. The clamp unit is positioned vertically, and all hydraulics are kept below the level of the table to avoid any oil contamination to the containers produced.

A key feature of the ECS SP 80 and SP 50 is that they both accept molds originally designed to run on equipment from major competitors. This is crucial in order to enter a market where there are already thousands of legacy molds to be utilized and to reduce the economical impact for the customer when changing from one equipment OEM to another.
