You can not. It is impossible for Heartgold and Soulsilver.
There is no Sinnoh to unlock in either game. If you want to access Sinnoh, you must buy Pokemon Diamond, Pearl, or Platinum Versions.
The Battle Factory is unavailable in Diamond or Pearl, but it is in Platinum, Heartgold, and Soulsilver.
I assume you are referring to the Pokemon HeartGold and SoulSilver games. If so, then I am sorry to say that it is impossible to get to the region Hoenn in those games. Beating the Pokemon Trainer Red is a great accomplishment, however it does not unlock another region.
after beating the elite four. the boat to the next region will dock there.
unofrtunately, you can't unlock the hoenn or sinnoh regions in heartgold or soulsilver. but i hear that the Pokemon executives are going to come out with a game that encompasses all the regions soon. (I think it starts with the hoenn region, then goes to kanto, then johto, then sinnoh.
