Hardening Time

WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2013 BMW 328xi, 2013 BMW 328i, 2012 BMW 328xi, 2012 BMW 328i, and 2011 BMW 328xi. However, it is still accessible from the selected car via links, so may be relevant.

The metal filler must be hardened using a short-wave infrared heater.

10 minutes at 50°C - pre-hardening (avoid formation of bubbles/blisters and pores)
10 minutes at 75°C - 1st stage hardening
10 minutes at 85°C - 2nd stage hardening (avoid material shrinkage)

IMPORTANT: In the first 10 minutes, the temperature of 50°C may not be exceeded. In contrast, a temperature that is too low may be equalized by extending the time.

NOTE: When the heater is used for the first time, the distances that match the temperature must be determined.

Switch the heater on and change the distance until the surface temperature of the metal filler no longer changes for a period of 2 minutes. Measure the temperature with a temperature gauge. When optical temperature gauges are used (Epsilon value 0.92-0.95), the heater must be switched off briefly during the measurement. Record the measurement
