Medical
ABS prototype for a medical OEM — CNC machined, painted, and silk-screened with final product graphics.
Aerospace
Multi-part aluminum 6061-T6 drone frame, 5-axis machined to ±0.05mm. Anodized in matte black.
Consumer
Ultra-smooth SLA prototype for industrial design review. Painted to final CMF spec for a consumer tech client.
Automotive
Vacuum cast PU prototype of a center console trim panel. 10 copies in 5 working days for a German OEM.
Electronics
SLS nylon prototype for a wearable health monitor. Functional snap-fit design validated in prototype stage.
Industrial
316L stainless steel surgical instrument prototype — mirror-polished and passivated to medical grade standards.
ZhongYing delivered 15 vacuum cast parts in exactly 5 days. Quality was outstanding — surface finish matched our production specification perfectly. Will use again for our next project.
We've worked with ZhongYing on 6 different medical device prototypes. Their DFM feedback is always helpful and the CMM reports give us full confidence in the dimensional accuracy.
Fast turnaround, great communication, and very competitive pricing. The aluminum drone frame came out perfectly — 5-axis machined exactly to our STEP file. Highly recommended.
