In Wenzhou, I visited a partner factory who makes sunglasses and optical frames. It was a pretty amazing tour in the factory to see how materials are being prepared, putting materials into the metal moulds, painting the frames manually, assembly and polishing of the temples, sanding, QC and a lot more. I was lucky to have met such very nice people during the trip and made me love to work directly with factories as I get to understand every single process. One thing to always remember during visits, be nice to your suppliers as they will be your partner as you grow bigger and they will be there to help on your production needs.
It won’t always be easy to find good suppliers in China that will have long term cooperation with you as some might just give up easily if the QC requirement is very strict compared to the price one wants to pay for their goods. But with proper communication and respect, things will be a breeze.
