13 years of proven precision machining experience delivers end-to-end manufacturing support for startups, innovators and global leaders. Complex designs are perfectly realized from first prototype to mass production.
*Achievable tolerances depend on material, geometry, part size, and finishing requirements. Critical features are reviewed before production.
200+ CUSTOMERS
We manufacture custom metal and plastic parts from your CAD files and drawings. With in-house CNC milling and turning, we support prototypes, small batches, and repeat orders for automation equipment, optical systems, and scientific instruments.
We review critical dimensions, material specifications, and finishing requirements before production, then inspect parts against the agreed specifications before shipment. Inspection reports and material certificates are available according to your project requirements.
Tenghui is one of the most reliable rapid prototyping companies. We can turn your designs and ideas into real parts in just a few days.
Custom housings, brackets, plates, and structural components machined from metals and engineering plastics.
Precision shafts, bushings, rings, and threaded components made to your drawings.
Laser cutting, bending, welding, and assembly for custom panels, brackets, and enclosures.
SLA, SLS, MJF, and metal printing options for prototypes and selected production applications.
Turn your designs into custom metal and plastic prototypes for form, fit, and functional testing.
