Vibrators for the plastics industry

Plastics are used in almost all areas of life. A wide range of different kinds of plastics are processed for electrical appliances, vehicles and packaging, as well as building technology, medical products and toys. However different the fields may be, the demands are complex. The plastics must be elastic or dimensionally stable, resistant to cold or heat and have special properties for sterile areas in the food and pharmaceutical industry.

NetterVibration has the right solution approach for conveying, dosing and sieving your granules and plastic parts, and for emptying containers. Your application is what is important. Our application consultants have years of experience in the plastics processing industry and are acquainted with the applications for vibration technology in your field.

Our application experts will gladly consult you on-site and help you find and implement the right solution for your application. We will support you wherever and whenever you need our experience.


Separating Large and Small Plastic Particles

A NetterVibration customer in the plastics manufacturing industry was working with plastic granulates of different sizes. In order to process the material quickly and efficiently, the customer needed to separate the granulate pieces by size as it was conveyed.

The customer purchased a Netter KRE 25-120 closed trough and sieve with dual outlets, one for larger particles and one for smaller particles. They then installed two Netter NEG 25210 electric external vibrators to the equipment. During processing, the smaller granulates fell through the openings of the sieve and were conveyed through one outlet, while the larger pieces stayed on top of the mesh and were conveyed through the other outlet.

Products used in this case study
  • KRE 25 120 with sieve and electric external vibrators by NetterVibration
    Customised Conveyors and Dosing Systems

    Feeders for conveying lettuce, dosing dry fruits, sieving gravel, and more. Whatever your product and application may be, we design a totally customized feeder adapted to your needs.

  • [Translate to English:] Serie NEG Drehstrom Elektro-Außenvibratoren
    Series NEG 3-Phase Electric External Vibrators

    Electric external vibrators of the series NEG are used whenever, for example conveyor chutes or sieves need to be driven. In addition, these devices can loosen material blockages adhesion in silos. The 3-phase NEG units run at 750, 1,000, 1,500 or 3,000 min-1 with a 230/400 V, 50 Hz power supply.

Emptying Big Bags Completely and ATEX Safely

A chemical industry customer frequently emptied large bags up to 1,000 liters/2,000 kg. of the product into a container, but was unable to empty the bag thoroughly. This required workers to manipulate the bag manually to make sure all of the product had been emptied. Their objective was to provide a way to automate the process so that the bags would empty thoroughly without requiring manual labor. Also, the environment is classified ATEX zone 22 because of the potential for dust so it was required that the system not produce any sparks or discharge static electricity.

The customer installed a NCT 55 E vibrator to a base assembly, allowing the contents of the bags to be thoroughly emptied. Also, the equipment was made according to ATEX Zone 22, eliminating the possibility of sparks or static discharge.

Products used in this case study
  • pneumatic turbine vibrators series by NetterVibration
    Series NCT Pneumatic Turbine Vibrators

    Pneumatic turbine vibrators of the series NCT are particularly suitable for moving bulk materials. They can be used for emptying containers and big bags, driving chutes, sieves and vibrating tables and for the mechanical stimulation of processes.

  • rubber element by NetterVibration under vibration table
    Series NRE, NTE, NOF and NAP Rubber Elements

    Rubber elements are used for isolating the vibration of mechanical components and to provide elastic support of vibration systems.

Plastic Granulate Through Rubber Pipes

NetterVibration customer in the chemical manufacturing industry was working with plastic granulate material that was required to flow through rubber pipes. Over time, the material would build up and adhere to the insides of the pipe, restricting flow. This had an adverse effect on efficiency and caused substantial downtime as the equipment had to be shut down so workers could clean the pipes and remove any material that had accumulated.

By installing a NTK 18 AL pneumatic linear vibrator, vibration is now applied to the flexible rubber pipe, improving the flow of material and resulting in a complete emptying and cleaning of the pipe. Efficiency and throughput have increased and downtimes for cleaning have been eliminated.

Products used in this case study
  • pneumatic linear vibrators series NTK by NetterVibration
    Series NTK Pneumatic Linear Vibrators

    The pneumatic linear vibrators of the series NTK are especially suitable for conveying and compacting bulk material, due to the completely linear vibration. The linear vibration is produced by a freely oscillating, self-reversing piston.

  • PKL 740 on pipe by NetterVibration
    Customised Consoles for Vibrators

    We have designed and manufactured vibrators and pneumatic knockers for pipes, moving structures, heat exchangers and complexe-shaped silos. Whatever the application, whatever your requirements, we will provide a customised solution, increasing your plant’s performance.

  • pneumatic maintenance unit NWE by Netter Vibration
    Series NWE, NFR and NOE Pneumatic Maintenance Units

    Our pneumatic maintenance units supply pneumatic vibrators with the right amount of clean and lubricated compressed air for each application.
