K 2013: BEKUM to launch energy-efficient machines

Electric or hydraulic, full or reduced clamp force, the customer is free to choose with BEKUM blow moulding machines. At K 2013, BEKUM Maschinenfabriken GmbH is premiering its fully-electric version of the current 7th generation blow moulding machines with a clamping force of 150 kN. This exhibit, a two-station EBLOW 407 D blow moulder, combines the modular structure of the 07 series with an energy-efficient, all-electric drive. The machine is equipped with a spiral distributor extrusion head that offers significant advantages for product quality as well as productivity.

Based on a standard platform, the proven 07 series is in use all over the world and can be ordered with electric or hydraulic drive systems according to the customer’s requirement. To increase production availability, the 07 series has been consistently geared toward ease of service. The fully-electric EBLOW models as well as the hydraulic HYBLOW models allow excellent access to drive components and valve stacks. The units can then be repaired or replaced very quickly, if required.

Mould width and extruder options

The EBLOW 407 D has a mould width of 500 mm with a mould length of 470 mm and a mould depth of 2 x 130 mm. The mould opening stroke is specified as 250 mm and the maximum mould weight is rated at 400 kg.  There is also a choice of three grooved barrel extruders with an L/D ratio of 24D, in screw diameters of 70 mm, 90 mm and 100 mm. Their plasticizing capability varies between 110 and 340 kg/hr. depending on the extruder size and the material being processes.

High extrusion quality with high-tech heads

BEKUM provides spiral distributor extrusion heads for its machines, which stand out due to the excellent, uniform parison wall thickness distribution.  This provides the operator with significant capability to optimize the parison quality for not only monolayer products, but especially for products with multi-layer structures. There is no need for the customer to compromise on user-friendliness either as the heads can be easily installed from the front of the machine.  Not only that, but the design of the head ensures quicker colour changeovers than with standard design principles, which lead to a direct increase in machine productivity.  Consumption of purge material for cleaning is also reduced to a minimum.

The compact design of the spiral distributor extrusion heads should also be noted because energy for heating them is significantly reduced due to less surface area.

The machine has a mould clamping system known as the C-Frame, which was introduced at K 2010 as an innovation, and has now been successfully launched in the marketplace. The design of the BEKUM C-Base Frame, which utilizes clamping platens that move along precise, low-friction linear guides, enables completely symmetrical clamp force distribution over the entire mould area, while maintaining high clamping platen parallelism.  The drive can maintain full clamp tonnage and gently cushion fast force changes, if required.Browse All Brands
