Did you know that tempering helps with the production of glass bottles and ampoules for the pharmaceutical industry?

The glass is formed under heat, which means there are residual thermal stresses and the glass is more likely to crack. For this reason, these thermal stresses must be removed before they are put into use. Stress relief is achieved by tempering.

Innovative MAX infrared ovens from Heraeus Noblelight support this process with convincing results.

Industrial infrared heating oven

The MAX ovens combine infrared radiation with convection and optimal reflection. Only quartz glass materials including QRC® nano-reflectors are used inside the oven.

From simulation to solution
The oven size can be adjusted to the product and the process. Numerical simulation in the design phase makes the heat process especially energy-efficient. To achieve a maximum product temperature of 900°C, a MAX oven needs less than ten minutes, and it can cool down in less than ten minutes as well. This enables rapid product changes. The MAX oven can be used for both batch and continuous operation.

MAX oven – especially energy-efficient
Tests show that in an oven with a heated length of 700 mm and a chamber cross-section of 150 x 150 mm the maximal emitter temperature is achieved within less than one minute. In continuous operation at 900°C holding temperature, the necessary holding power is just about 3 kW, due to the excellent energy efficiency.
