Customer Reviews

Anya Forger

Marco Rossi

“Service is excellent.”

The hollow parts we design are quite complex, and most manufacturers directly refuse the order. However, you not only achieved precision with five-axis machining to the finest detail, but also delivered a mirror-finish surface that is of artistic quality. What’s even more impressive is that each delivery comes with a testing report, providing such transparency that it gives us full confidence when delivering to our customers.

Sofia Conti

“Truly professional”

We needed a custom-shaped, lightweight suspension shell that would ensure strength while controlling weight and also be compatible with a special surface treatment process. Yumei team not only helped us optimize material selection but also integrated the parts through multi-axis machining, eliminating the need for subsequent assembly steps. After vehicle testing, the impact resistance and durability fully met the demands of complex road conditions. Their professionalism is truly reliable!

“The products are very reliable.”

Last year, during the peak season, we had an urgent order for micro connectors for the braking system, requiring machining with Swiss CNC machines and compatibility with titanium alloy. After contacting Yumei, they completed production in 7 days. Their ability to handle emergencies and their professional standards have made them our core supplier, without a doubt!

We can also engage in the processing of parts for more industries.

A: With the rapid development of motorcycle manufacturing technology, efficient, high-precision, and highly stable component milling has become a crucial means to shorten production cycles and enhance enterprise efficiency and competitiveness.

CNC machining services can easily achieve rapid prototyping and batch production of motorcycle components. Compared to traditional manual manufacturing, CNC machining technology lays a solid foundation for the standardization and consistency of motorcycle component production. CNC machining services also provide comprehensive automated manufacturing solutions for various customized motorcycle parts.

A: Composite materials are prone to cracking or delamination during machining, requiring careful control of cutting force and temperature.
Coating Damage Risk: Special coatings may be compromised by high temperatures or mechanical stress.
Uneven Thermal Expansion: Materials may deform unevenly when heated, necessitating strict temperature control.

A: Our samples can be done within 1 day as soon as we have raw material in stock and there is no surface treatment for the part,3-5 days is our normal time for the samples,regarding the mass production time,it depends on the order quantity,normally 7-15 days.
