ringceramicsilicon nitride

Ceramic heating rings made of silicon nitride can be produced with an outer diameter of up to 300 mm. A typical extent of the rings is 5 mm. The good thermal conduction and the low thermal mass of the ceramic material allow extremely fast heating rates, a uniform temperature distribution and high control accuracy. The high strength of hot-pressed silicon nitride guarantees high stress resistance and excellent wear resistance at short processing times. We provide heating rings for operating in the open air at temperatures up to 500 °C. Higher temperatures (if required) could be achieved by developing specific technical solutions. Customized design Our in-house designs make any modification in size (inner and outer diameter) or performance simple and convenient. Mounting-bracket holes and openings for temperature regulation can be added to the design. Our heating rings come already flat ground, however they can be ground further up to a flatness of < 10 μm to meet specific requirements. A variety of shapes formed to the contour of the product or tool to be heated are possible as well. Advantages Your advantages: You can generate the heat exactly at the spot where it is needed You can reduce cycle times and increase yield in your process You save process cost and energy You can eliminate preheating or reduce time for heating up Your system to few minutes Your machine can become smaller and lighter thanks to the reduction of mass and volume of the heating components
