Kosme KSB 1XXL, 2XL & 2XXL

The linear stretch blow moulding machines represent a systematic continuation of the rotary blow moulders in terms of container size. While the rotary lineup reaches its limits at a container volume of about 10 liters (2.64 US gallons), Kosmes linear blow molder portfolio takes over, handling containers with volumes of up to 30 liters (7.9 US gallons). The linear line can also produce small containers starting from 2.5 liters. A notable feature is their ability to handle nearly all preform types available on the market, making the linear line a true all-rounder. The maximum output for the linear lineup is about 3000 bottles per hour.

The lineup of linear machines is categorized into three groups. The numbers indicate the cavities, which relate to the output rate, while the XL and XXL designations refer to the maximum container volume that can be produced:

• KSB 1XXL: The first choice for containers up to 30 liters
• KSB 2XL and 2XXL: Higher output due to two available cavities instead of one and volumes of 15 liters (2XL) up to 25 liters (2XXL)

Like our rotary line, these machines include an electrical servo-driven mechanical stretching mechanism, allowing for variable-speed stretching of heated preforms. This ensures optimal preparation and blowing results while further reducing the need for compressed air.

With the semi-automatic mould change system ‘Zero Clamp’ a fast changeover for the moulds is ensured to keep machine down time as low as possible and stay flexible for ever-changing market demands.

Sustainability is significantly enhanced with the Air Wizard Plus system, which recycles compressed air for underlying processes already available in the system, instead of using freshly compressed air.

To further improve energy efficiency, ceramic reflectors are used in the heating process to reduce energy loss. The neck cooling system, equipped with a heat exchanger, keeps preform-necks in shape and properly tempered.

KSB 2XL machines feature nine heating zones and a patented system for tool-less adjustment of the heating lamps, achieving optimal heating conditions while reducing energy consumption.

Preferential heating options for non-uniform heating of preforms are recommended for blowing oval or generally asymmetrical containers to achieve superior results in comparison to the standard heating process
