The future is electric

BEKUM's EBLOW 37 is a blow-molding machine for high-performance production of blow-molded articles.
The popularity of all-electric machinery has enabled many manufacturers to achieve cost savings and consistently high quality of the finished products. In this area, blow-molding machine manufacturer BEKUM has developed and expanded its electrical series EBLOW. The latest addition is the EBLOW 37 for packaging applications, and it premiered at K 2016 to specialists in the industry. As early as 2007 BEKUM presented the first electric blow-molding machine at the K-Messe (plastics trade fair) in Duesseldorf. The continual development of the machine range was followed by the introduction of the EBLOW 07 series with patented C-frames.
The newest development of the Berlin technology leader is the EBLOW 37, a blow-molding machine for high-performance production of blow-molded articles, especially for canisters. With this model BEKUM is looking to win points in the packaging sector, particularly from producers who are interested in an energy-efficient, flexible machine solution tailored for high-performance.
Improved added value
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 experience from the manufacture of the EBLOW electric packaging 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. Typically, this model is targeted toward canister manufacturers all over the world. According to BEKUM, the high-performance EBLOW 37 provides canister manufacturers with the option of upping their added value through increased output volumes.
The machine has the best of both worlds - an energy-saving system with fast closing pressure build-up. The EBLOW 37 follows the performance of the BA 34.2 without compromises. Here, BEKUM is relying on a new energy-saving system for the movements of the machine: Closing unit and mold 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 advantages from both types of drive technology.
Pure high performance
With a closing force of 370 kN and a mold width of 700 mm, canister production is the domain of the EBLOW 37. According to BEKUM, the comparison measurements of the single-station machines are very promising. Compared to a conventional hydraulic solution, the EBLOW 37 enables production to be increased by up to 15%. This corresponds to an output volume of 240 pieces per hour based on a 20 l lightweight canister as reference item. These values recommend the EBLOW 37 as a new standard in its class.
BEKUM provides its machines with spiral distributor blow heads, which feature excellent, uniform wall thickness distribution 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 machine. And not only that: the design of the head enables faster color changes than standard design principles, which leads to a direct increase in machine productivity. Change material 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 required 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 flexibility. The setting of blow molds with different mold thicknesses can be performed quickly and very conveniently thanks to a production-optimizing automated calibration run. In combination with the company’s own specially designed and produced extrusion heads with spiral distributor technology, the EBLOW 37 also impresses on the material side. Many blow-mold materials made from HDPE and PP in single- and multi-layer designs (3-layer and 6-layer), including those with transparent strips and polycarbonate, can be processed with excellent results. The new design allows very fast color changes for the highest level of flexibility and cost efficiency. Through the use of a characteristic BEKUM top or bottom calibration, the production range can be expanded even further. Many proven and process-safe options of the familiar BA 34.2 will also be available in the new EBLOW 37. The future is electric – including in the packaging.
Trendsetting in blow molding technology
Founded in Berlin in 1959, BEKUM Maschinenfabriken GmbH is one of the world’s leading manufacturers of extrusion blow molding machines. Founder Gottfried Mehnert conceived the name BEKUM as the acronym (Berliner Kunststoff Maschinen). The company began to flourish in its founding year with the development of the world’s first neck-rim calibration. Numerous innovations and patents followed, confirming that BEKUM, with its innovative and customer-oriented machinery solutions, has always been ahead of its time – and remains so to this day.
With future-oriented and reliable production processes and fully electric, as well as hydraulic machinery for the commercial production of blow molded containers ranging from 5 ml to 3000 l, BEKUM offers everything for plastic packaging from one source.
Process reliability, availability, efficiency and sophisticated design characterize the standard of BEKUM production lines for blow molding.BEKUM contributes the expertise that has grown based on these references, associated with various patents in blow molding, to the fulfillment of every customer requirement.
