How to Select a Good Pigment and Solvent Dye Supplier?

You either have to have a 'friend' who is already in the same business who is willing to share their experiences and is probably not willing to share because you are a competitor, or you can listen to each of their salespeople who will tell you that they are the best and the rest are not the best, or you just have to try one and see if you like them. Repeat until you are happy.

Maybe Angie's List will have ratings on them?

Dear Brave Sir Robin,

Thank you very much for your comment.

Your comment enlightens me and I will pass your comment to my friend.

And please allow me to say THANK YOU TO YOU for my friend.

Thanks again!

You don't "just start" a plastics factory with knowledge of the materials and processes involved.

And a "plastics factory" could define many different things.

I'm guessing it may be an injection molding shop. But, who knows.

If you want consistent color matches, paint the parts. Robotic painting is consistent and cost effective.

If you insist on doing this, select a supplier who will educate your friend's processors and operators in how to use their products.

This sounds like a recipe for disaster if nobody knows what they're doing.

Dear Lyn,

Thanks a lot for your comment!

I will tell my friend to keep learning relative knowledges and skills.

And please allow me to say THANK YOU TO YOU for my friend.

Thanks again.
