Why buy a CEMAS vibration machine

clear and irrefutable strong points

  • Realtime tuning

    Our innovative generator is able to adjust the vibration frequency with no autotuning procedure. Internal values are checked and updated every 5ms to constantly ensure a perfect match of the equipment with the machine.
  • Wide rear opening

    Since the very beginning, all our vibration range was conceived to get tool change from the back of the machine, as maintenance door opening size always exceeds the width of the press bed.
  • Sound proof structure

    Hydraulic power-plant outside the working area.
  • Quick vibration stop

    This cutting edge feature can zero the vibration in less than 50 ms, for a more homogeneus and resistant joint.
  • Compact but complete

    CEMAS machines are the most compact machines available on the market, keeping engineering and vibration features unchanged, thus favoring ergonomics.
  • Always available

    Our standard machines are always available and can be rent to face even the most stringent production requirement in case of sudden demand increase.
  • 63 tool memories

    The machine can store up to 63 different equipment parameters, of which 31 are automatically acknowledged. Data can be easily copied to other machines if needed.
  • Highly customizable
  • No compromise for quality
  • Easy maintenance
  • Ergonomic loading station
  • Reliability
  • Energy saving technology
  • Innovative and user friendly UI
Cutting edge technology and fully equipped machines as standard. Discover more
  • Highly customizable

    Many standard features included in our machines are optionals for competitors and, should this not be enough, just turn the page to discover a full range of over 60 optionals for your tailor-made machines.
  • No compromise for quality

    All components used by CEMAS are from world leading suppliers and never sub-brands.
    Safety is our ultimate goal, as well as a prompt availability of spares worldwide.
  • Easy maintenance

    The use of the latest-generation electronic components has resulted in a remarkably smaller control panel, and in positioning the hydraulic unit below the control panel for the 240 Hz machines. This change has totally cleared an inner compartment and has made tooling maintenance and set up operations easier.
  • Ergonomic loading station

    Special care was devoted to the manual loading steps of the process, both for small and large machines: to minimize effort on the backbone, the loading/unloading area was kept as close as possible to operator. There are no machines of the same class available on the market where this distance is so small.
  • Reliability

    Light curtains are fitted as a standard to ensure maximum operator safety, further to decreasing the total cycle time of each welding. Light curtains are integrated to protect them against collisions and as a result of an extremely accurate and well defined design.
  • Energy saving technology

    Big welding area and low power required: this is energetic efficiency!
  • Innovative operator interface system

    Accurate does not mean complicated: no other machine on the market is so "user friendly".
    We have made a big effort in designing our video graphic to simplify any operation. Actually, there would be no need for operator's training.
    • Switching to your language is as simple as pressing a key.
    • Parameters can be set to include up to 8 different welding steps.
    • Tool movement graphic programming: no need to call us for a new tool!
    • Monitoring of the "just in time" process by displaying welding diagrams.
    • Constantly linked to CEMAS through the Teleservice system for diagnostics and customer's service on line.

The vibration welding technology

Joining by melting two surfaces in contact

The joining of thermoplastic materials by using vibration welding is carried out by melting the two surfaces in contact.

Friction between the two components

The welding method is a clutch for which there is no need to supply heat from the outside: it comes from the dissipation of the energy produced by friction between the two components.

Rubbing between the two components

The local temperature increase, necessary for the welding process, is obtained by the rubbing between the two components, able to melt the welding perimeter of the two pieces to be welded.
