After several years of buying and selling internationally, I was able to identify serious suppliers with solid and reliable equipment.
Building a factory requires a lot of parts. There are many suppliers, with multiple ranges of products. Many of these suppliers have only a small site in their national language, which makes them even more difficult to find. Moreover, there should be no mistake about the purchase price, the expected lifetime, the operating and maintenance costs, the quality of the component materials or the quality of the documentation transmitted.
