What Makes Us Extraordinary

GUAN SHENG shares a continuous growth of 300%+ year-over-year annual growth in

rapid prototyping services. These are the features that make us stand out.

Engineering support

More than making parts, we provide value. From early-stage material selection, custom prototyping design advice, to money-saving tips and technical suggestions based on experience for end-use production, we provide professional engineering support on a part-by-part and assembly-by-assembly basis.

Quality assurance

Quality comes first at GUAN SHENG. As an ISO 9001:2015 certificated company, we provide SGS, RoHS, material certifications, and full dimensional report for our customers. A First Artical Inspection Program is also available on your request.

Preferred Online Manufacturing
Platform for Product Designers and
Engineers

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.
