BEKUM:
new electric blow-moulding machines
T
he blow-moulding machine manufacturer BEKUM is ex-
tending its electrical series EBLOW. The newest addition is
the EBLOW 37 for packaging applications. It premiers at the K
2016 to specialists in the industry. As early as 2007 BEKUM
presented the first electric blow-moulding machine at the K
Messe (plastics trade fair) in Duesseldorf. The continual deve-
lopment of the machine range was followed by the introduc-
tion of the EBLOW 07 series with patented Cframes.
The newest development of the Berlin technology leader is the
EBLOW 37, a blow-moulding machine for high-performance
production of blow-moulded articles, especially for canisters.
With this model BEKUM is looking to win points in the pak-
kaging sector, particularly from producers who
are interested in an energy-efficient, flexible machine solution
tailored for high-performance.
Improved added value with the EBLOW 37
The EBLOW 37 design has its roots in the hydraulic machine
range. For the Berlin company however, the future is now also
electric. The goal of the new innovation was to take the ex-
perience from the manufacture of the EBLOW electric packa-
ging machine series and combine it with the advantages of
the proven BA 34.2 hydraulic canister machine. The hydraulic
BA 34.2 has been successfully positioned in the market with
over 200 machines.
Now BEKUM is transferring this to an electric generation of
machines, which offer a technically and economically attractive
solution for producing articles between 10 and 35 litres. Typi-
cally, this model is targeted toward canister manufacturers all
over the world.
According to BEKUM, the high-performance EBLOW 37 pro-
vides canister manufacturers with the option of upping their
added value through increased output volumes.
Energy-saving system with fast closing pressure build-up
The EBLOW 37 follows the performance of the BA 34.2 wit-
hout compromises. Here, BEKUM is relying on a new energy-
saving system for the movements of the machine: Closing unit
and mould closing function are electrically driven, while the
closing pressure build-up for effective force transmission is
achieved through servo hydraulics and is thus available
quickly as usual. This hybrid principle makes use of the ad-
vantages from both types of drive technology.
Up to 15%more output volume with 20 l canisters
With a closing force of 370 kN and a mould width of 700 mm,
canister production is the domain of the EBLOW 37. Accor-
ding to BEKUM, the comparison measurements of the single-
station machines are very promising. Compared to a
conventional hydraulic solution, the EBLOW 37 enables pro-
duction to be increased by up to 15%. This corresponds to an
output volume of 240 pieces per hour based on a 20 l light-
weight canister as reference item. These values recommend
the EBLOW 37 as a new standard in its class.
High extrusion quality with high-tech spiral distributor
BEKUM provides its machines with spiral distributor blow
heads, which feature excellent, uniform wall thickness distri-
bution in the pre-form and the finished article. This results in
significant potential for the operator to optimise the parison
quality not only for single-layer products, but especially when
it comes to products with a multi-layer structure. And there is
no need for the customer to compromise on user-friendliness
either: the heads can be easily set from the front of the ma-
chine. And not only that: the design of the head enables
faster colour changes than standard design principles, which
leads to a direct increase in machine productivity. Change ma-
terial for cleaning is also reduced to a minimum. The compact
construction of the spiral distributor heads is also impressive.
Their smaller surfaces mean considerably less energy is requi-
red to heat them.
Flexible application expands the range of production
BEKUM’s many years of manufacturing know-how from the
packaging sector has gone into the machine development of
the EBLOW 37. The user can thus expect a high degree of fle-
xibility. The setting of blow moulds with different mould thick-
nesses can be performed quickly and very conveniently thanks
to a production-optimising automated calibration run.
In combination with the company’s own specially designed
and produced extrusion heads with spiral distributor techno-
logy, the EBLOW 37 also impresses on the material side. Many
