Which constant force spring company doing OEM?
Depending on the ubiquity of constant force spring, you can narrow down your search via an OEM’s product offering page on Alibaba, Global Sources, Made in China, etc. If it is a more specific and single product, then you may be able to follow up in this way. However, if you are not able to see through such channels, you can also search for product descriptions or brand names via shipping/export monitoring software such as ImportGenius. Please note that many OEMs will be compliant with the production request, but some will understandably be hesitant depending on whether there are agreements to safeguard the details of product production.
