CEMAS elettra - Your partner in plastic joining

The ultimate range in IR/HP technology.
RELIABLE as ever, even more efficient

Hot plate since 1986

The hot plate welding machines are part of our traditional production since 1986, and nowadays CEMAS ELETTRA owns a remarkable know-how linked to this technology.
Nowaday we provide three different models of standard machines, all of them "full electrical".

Infrared: the new way

Starting from 2007, CEMAS ELETTRA has also developed different infrared applications suitable to be applied to the same range of machines. Currently infrared is one of our best-seller technologies, further proof of the reliability of our machines.

Why buy a CEMAS infrared welding machine

  • No design limits

    IR and HP welding processes are characterized by a great design flexibility that allows high joining performances, even for the most complex shapes.
  • 128 tool memories

    The machines can store up to 128 different equipment parameters, automatically recognizable. Data can be easily copied to other machines, if needed.
  • Full electric

    Thanks to an "user friendly" electrical engine, able to meet even the most stringent requirements, the machines are cleaner, speeder and really efficient from a power consumption point of view, especially if compared to the traditional hydraulic machines. These machines ensure an incomparable production rate capability.
  • Precision

    Full electric means unmatched repetitiveness, accuracy and fluidity in movements dynamics and, for this reason, guarantees an aesthetically perfect and clean joint. Moreover, the user interface allows the complete control of all the welding parameters, offering the possibility to monitor and, if necessary, to instantaneously change heating settings.
  • Low power consumption

    The infrared metal-coil emitters are heated instantaneously ate the time of welding. During the rest of the process the system works in standby mode, significantly reducing the power consumption.
  • Smart technology

    Depending on the molecular structure of the materials to be welded, using specific bands of medium-wavelength, it is possible to obtain a high transmission of power and an excellent absorption.
  • Non-contact = clean

    Welding without contact is particle-free and allows to avoid problems of smokes and residual molten material: materials will maintain their natural consistency (without deterioration); this is very important for all materials and even indispensable for low density materials such as PE-LD and the polystyrene. Moreover, it is not necessary to clean the "plate", as it happens for the traditional hot plate machines.
  • Modular and flexible

    The irm control modules are powered by specifically designed power units. Even the electrical power system is completely modular and can be freely configured based on specific customers' needs.
  • 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.

ApplicationS

CEMAS IR / HP machines: electrical movement and first rate materials

In addition to the technical advantages offered by the IR/hot plate technology, CEMAS IR/Hot plate machines are full electric and always equipped with top class materials and components. For this reason, our machines ensure the highest welding standards in terms of flexibility, quality and cost-effectiveness.

The infrared welding technologyThe new way to weld by irradiation without contact

High design flexibility

The infrared welding process uses a non-contact heat input issued from medium-wavelength metal-foil emitters (that reach surface temperatures between 800°-950°).
Emitters with metal coil are mounted on ceramic substrates, and manufactured to exactly follow the welding profile, allowing a really high design flexibility; they are not enclosed in any container and this significantly increases the efficiency of the emission. The welding zones are controlled and managed individually and each emitter is operated by its own controller: irm (Infrared Module). This feature is particularly important when dealing with heat-sensitive parts.

The evolution of hot plate technology

Infrared technology is the "natural" evolution of the hot-plate technology. It has been developed to overcome some critical issues that, following the introduction of new welding materials, have become more and more evident, particularly in recent years.

THE CEMAS WAY

Proprietary technology and a fully scalable modular architecture

The irm

The core of our innovative system is the irm 3.0, a microprocessor based device able to manage separately two different channels, in order to perform an optimal use of each metal-foil. This unique feature dramatically optimizes the space management, maintaining a high output power.

The plc

The ultra fast protocol communication enables a fully digital modular architecture. For unrivaled management, diagnostic and flexibility.

The power units

The irm control modules are powered by specifically designed power units. Even the electrical power system is completely modular and can be freely configured based on your specifical power needs with virtually no limits.

The modular architecture

The Hot plate welding technologyThe simplest and intuitive welding system existing to date

How it works

The hot plate, working at a higher temperature than the material point of fusion, is closed in between the two elements to be welded.

After a certain heating time (required for the surfaces melting), the hot plate is quickly removed and upper and lower tools are pressed one against the other, welding the plastic components and creating welding flash.

NEW TECHNICAL SOLUTIONS

CEMAS solved the issue related to the adhesion of molten material to the plate walls by applying on it a non-stick coating, called Teflon, or by constructing plates in steel or special bronze alloy and by increasing their temperature.
In this way the residual material on the plate is vaporized, leaving it always clean.
To ensure an optimal welding process, it's also possible to set the melting parameters: heating time, cooling time, heating depth, cooling depth, heating pressure, cooling pressure.
