The site looks good.
I don' t have much idea about the tooth-brush packaging machine manufacturers, but you should ask for the reference customers list from CN-Thermoforming and then try and visit / speak with any of their reference customers.
It will be good to look, check and findout the total cost of ownership, technology used, service support in your area, integration of the machine with upstream & downstream machines, relevant standards, competitor machine advantages, value for money preposition etc.
I am sure, somebody else on the forum would have experience / suggestions for the relevant machinery.
All the very best in your search!
