Bekum attaches particular importance to the energy efficiency of an extrusion design, the extruder being the main energy consumer of every blow moulding machine. With this concept a significant energy saving of up to 20% will be realized, at the same time as high melt quality and low temperatures.
The uncompromising use of energy-efficient drive techniques and production technologies means we make economic and environmentally-friendly production possible for our customers. The extruder requires the greatest share of energy. Our extruders are equipped with synchronous servo motors in highest efficiency class IE5 (super premium efficiency). The energy required by extrusion blow-moulding machines is standardised, allowing comparable measurements in accordance with Euromap 46.1.
In order to ensure that use of new (virgin) plastic material is kept as low – and therefore as sustainable – as possible, Bekum provides a range of different solutions. One is the use of article waste from own production and/or recycled materials, which are also known as PCR (Post-Consumer Recycled). Using the co-extrusion method (which involves combining several layers), recycled materials can be re-used as a substitute in the middle layer. This considerably reduces the share of new material required for the outer layers. Calcium carbonate (chalk) also represents an environmentally-friendly alternative for the middle layer in co-extrusion. This inexpensive solution is characterised by good barrier properties and lack of any taste, which has advantages for the use of this promising technology in the food industry as well.
Bekum's newly developed magnetic quick-change system for blow moulds and accessories, which made its première at the NPE 2018 trade fair in Orlando, USA, is setting a new benchmark for speed. A change of mould, including blowpins and handover system, is now possible is less than 15 minutes per clamping unit. The change of mould does not require additional tools, and is carried out by magnetic forces and using quick couplings, in just a few motions following step-by-step instructions on the control system display. The mould is released at the front using an integrated transfer tables. Flexible, safe and practical!
Crystal-clear containers with handles and made of PET are produced in reliable processes, and exclusively on Bekum blow-moulding machines. The intense development work pursued with material manufacturers of PET, as well as with leading processing operations, which ranged from the design of the extrusion system to blow mould production, material drying and the use of recycled materials, and even flash removal in the machine, means Bekum has optimised PET processing for extrusion blow moulding. By integrating the PET material for extrusion blow moulding into the recycling classification 01 for PET, the recyclability has been improved significantly.
The automation solutions from Bekum link up different steps along your production process, and create transparency within the overall system. This allows optimal resource planning while boosting productivity at the same time. From material supply to dosing, from transport and testing systems to recycling management, man process steps are integrated into the logic of the blow-moulding process, and are optimised to cater to your production requirements.
The new overall size of the EBLOW 1208D with a clamping force of 500 kN for blow mould widths of up to 1,260 millimetres make high-output production possible, particularly for bottles and containers with handles. Its clamping unit is based on the well-established and patented C-frame for perfect clamping force distribution, thereby ensuring the highest article qualities. The Tandem Blow process, developed by Bekum, allows two articles to be produced from one extruded parison. The base-to-base blow-moulding of articles with lost blow cavities for single-station and double-station machines increases the output rate by 100 percent. Bekum employs a cooling station with an external punch for high output rates in 20L canister production.
Plastic packaging makes a decisive contribution to extending the shelf life of foods and sensitive contents. The co-extrusion methods allow several different material layers, comprised of original, recycled, barrier and adhesive agent material, to be combined with each other. The combination then exhibits new properties that the individual materials cannot offer alone. Furthermore, aseptic bottles and vials can be produced using a sterile blow-moulding process. Both methods provide technically economic solutions for the highest of demands for shelf life extension for a wide range of industries, such as food, cosmetics, agrochemicals, pharmaceuticals and medicine.
