How do mould tool sales find their customers?

Hi my fellows, shall I to say that it is my honer to be here and communicating with you about this topic-how we get a clue, an useful and available solution to find your customers? If I say, that will be a bullshit.

In fact, such a industry like mould or mold, that is totally ODM (Original Design Manufacturing), so how can we get a message posted on the webs?
Perseverance + the way suitable to you and your area, and luck, that may be the most practical solutions here I throw to you guys.
Thanks for reading.

Good luck.
