Nabertherm Sintering Furnace LT 02/13 CR for Cobalt-Chromium

Nabertherm LT 02/13 CR sintering furnace for cobalt-chromium

The Nabertherm LT 02/13 CR sintering furnace is a specialised furnace solution for dental laboratories and dental materials science, developed for high-temperature sintering of cobalt-chromium restorations under a controlled argon atmosphere. The device is aimed at professional users who value process accuracy, material purity and safe, energy-saving work processes. The innovative sintering bell and high-quality components make this sintering furnace the first choice for high-quality dental restorations and versatile laboratory applications in the field of cobalt-chromium. Compared to general high-temperature furnace solutions, the LT 02/13 CR offers a specially optimised environment for cobalt-chromium, reduced argon consumption costs and uncompromising process control. Technical features and innovative equipment

With its precise control and insulation technology, the sintering furnace is an indispensable component for modern dental laboratories and research-oriented institutions. The most important technical specifications and special features at a glance:

• Maximum temperature: 1300 °C - ideal for sintering cobalt-chromium alloys
• Internal dimensions of usable space: 130 mm × 120 mm × 120 mm; usable volume 1.9 L
• External dimensions: 422 mm × 320 mm × 430 mm (with compressed air connection for rapid cooling: additional 230 mm)
• Energy efficient: 2.2 kW connected load, suitable for 110 V - 240 V, single-phase (1/N/PE or 2/PE)
• Weight: approx. 25 kg
• Heating time: only approx. 35 minutes to maximum temperature
• Sintering bell allows argon atmosphere for up to 30 units per cycle with minimum process purge rate (1 l/min)
• Controller C550: storage of up to 10 sintering programmes with 20 segments/programme each
• Double-walled, stainless steel construction for safety and temperature stability

Special features: The specially developed sintering bell for argon gas flushing ensures a virtually oxygen-free atmosphere in the sintering chamber. This reliably eliminates oxidation processes on the cobalt-chromium alloy, which is reflected in optimised surface quality and durability of the dental restorations. The option of rapid cooling via an integrated compressed air connection minimises downtime in laboratory operations and significantly increases productivity. In addition, the LT 02/13 CR consistently avoids the use of potentially hazardous insulation materials such as aluminium silicate wool.

Further technical details

In addition to the data already mentioned, the furnace impresses with its low argon consumption, intelligent control system and robust stainless steel construction, which keeps the outer shell cool and thus minimises the risk of burns. The programmable temperature control allows individual cycles for a wide variety of dental alloys and other materials to be optimally controlled. The fully insulated heating chamber ensures excellent temperature homogeneity and process reliability. Certifications and standards

The sintering furnace complies with the requirements of EU Regulation (EC) No. 1272/2008 (CLP) for safe laboratory equipment and consists exclusively of non-classified insulation materials. Health safety is a top priority in this model. The design complies with the currently valid requirements for electrical dental laboratory equipment.

Typical areas of application in laboratories and research

• Manufacture of cobalt-chromium restorations in dental laboratories
  For single crowns, bridges, bars and removable partial dentures based on cobalt-chromium, which offer exceptional strength and excellent long-term compatibility.
• Dental rehabilitation
  Precise sintering of complex prosthetic restorations such as attachments, telescopic crowns and secondary constructions, where freedom from oxidation and dimensional accuracy are crucial.
• Materials science and research
  Analyses and innovative developments in the field of dental cobalt-chromium alloys, e.g. comparison of sintering parameters and their effect on structure and strength.
• Manufacture of implant abutments and custom-made products
  Optimal conditions for sintering precision-engineered structures under protective gas, e.g. for complex occlusal screw-retained work. Typical materials processed with this model are cobalt-chromium, but the open, programmable control system allows the process parameters to be modified for other dental alloys and high-performance ceramics.

  FAQs

  How is the furnace operated and programmed?

  The furnace is controlled via the intuitive C550 controller. Users can create up to 10 programmes with 20 segments individually and thus save different sintering profiles for different materials.

  How is the argon atmosphere generated and controlled?

  Argon is efficiently introduced via the professional sintering bell. The process purge rate can be precisely regulated (standard: 1 l/min), ensuring a constant, virtually oxygen-free working atmosphere.

  Can different batches (e.g. different restorations) be sintered at the same time?

  Yes, up to 30 dental units can be processed under the sintering bell per sintering process without any loss of quality or homogeneity.

  What maintenance measures should be observed to ensure a long service life?

  The double-walled stainless steel construction and high-quality insulation materials ensure low maintenance requirements. It is recommended to regularly check the tightness of the sintering bell and to maintain the device in accordance with the manufacturer's instructions.

  Conclusion

  The LT 02/13 CR sintering furnace offers dental laboratories and research institutions a highly specialised solution for the precise and safe sintering of cobalt-chromium restorations under argon protective gas. With its uncompromising freedom from oxidation, short process times, user-friendly control and building-friendly design, this model sets standards in the field of dental heat treatment. If you value maximum quality, safety and efficiency, the LT 02/13 CR is a future-proof choice.
