I understand that one would use a vacuum pump to evacuate a light bulb, but once a vacuum is created, how is the bulb sealed without air coming in?

SUMMARY
The vacuum in a light bulb is created using a vacuum pump, which removes air from the bulb before sealing. The sealing process occurs simultaneously with evacuation, utilizing a heating method in a press to ensure that no air can enter the bulb once the vacuum is established. This dual-step process is critical for maintaining the integrity of the vacuum, which is essential for the bulb's functionality and longevity.
