Preferred Online Manufacturing
Platform for Product Designers and

I have received the parts yesterday. Thanks for supporting my project within such urgent lead-time. The manufacturing process updates and logistics tracking helped a lot.

Getting the quotation online is a mind-blowing experience, and the result turned out to be impressive. It saves me a lot of time and effort communicating. What’s even better is I was still provided a dedicated Sales Engineer for person-to-person communication if necessary.

The FAI parts arrived on Monday. Thanks for the prompt service and attention to our order. We have inspected the parts and installed them in one of our assemblies. The quality, fit, and finish are excellent. Please proceed with the rest of the production order.
