Sustainable and efficient drive concepts for the plastics industry at the K 2022

Numerous companies in different segments of the plastics industry have opted for the innovative power of Baumüller for many years – including market leaders in the film manufacture, injection casting, extrusion, thermoforming and blow molding sectors, as well as the recycling sector. The solution portfolio highlights for servo-hydraulic, hybrid and fully electric plastics machines can be seen on the trade fair stand.

Compact and low-maintenance: Direct servo pump attachment with the “Performance Line”

A patented trade fair highlight is the servo pump direct “Performance Line” attachment, which is practically maintenance-free thanks to its self-lubricating internal gearing. Direct attachment also means that the coupling and pump support can be omitted. The resulting shorter installation length enables a smaller machine installation area. Due to the flexible design of the motor flange, the motor’s installation position can be freely selected and adapts to the respective machine design.
Baumüller offers drive systems for servo hydraulic solutions that are low-maintenance and energy efficient

Automation and drive solutions for plastics machines

The converter series b maXX 5300 includes feed-in and regenerative units as well as drive units, which can be quickly and easily combined by an integrated drive connect system. This allows the machine builder to benefit from low installation costs and short commissioning and service times. The controllers impress with their high power density and very small installation space. The power supply units have been expanded to include peak outputs of up to 300 kW. This is ideal for the plastics sector, because short-term high peak power outputs are often needed for dynamic movements such as the opening and closing of the closing unit.
In addition to the b maXX 5300 side-by-side system, the b maXX 5500 mono units are also available. Power outputs from 1.1 to 315 kW can therefore be covered. The entire b maXX 5000 series also offers higher safety functions such as SLS (Safe Limited Speed) and SLP (Safe Limited Position) directly in the drive and a large number of cooling options for optimum use.

Water-cooled torque motors impress with their highly compact design and optimal heat removal. Direct coupling achieves high stiffnesses and therefore very good force transfer together with ideal control properties. The execution as a hollow shaft variant improves accessibility and enables media and tools to be fed through. For example, spindle drives can be integrated in a hollow shaft. This enables optimizations in the compact machine construction and in the process engineering.

Special solutions for plastics machines

Several industry-specific drive components are also exhibited on the trade fair stand. One example is a torque motor version with thrust bearings. These thrust bearing motors were designed for use in extruders. Here the extruder screw is directly coupled with the motor shaft. The motor can therefore be connected in a space-saving and direct way, even under the high prevailing axial forces.

Another example is the electrical ejector drive DSC1-135. The direct ejector is a high acceleration drive specially designed to meet the requirements of the Injection molding machine. The motor also has a special bearing to compensate for axial forces and impresses with its very good dynamic properties. Thanks to the space-saving design, optimal and flexible integration in the machine is possible. The contamination of end products in the tool space, for example, due to oil or dirt particles, is avoided by using the direct drive technology. The synchronous direct drive is therefore a cleaner, more energy efficient and extremely dynamic drive.
