Prototyping & Rapid Tooling Solutions
Efficient product development for Smart Hardware, EV Components, Enclosures, Medical Devices, and Sports Tech
Founded in June 2013. It was born from the desire to offer the one-staop solutions in terms of design, prototyping and creation of components through engineering know-how gained over the years.
We support projects from early-stage startups to established enterprises, offering CNC machining, rapid tooling, vacuum casting, and 3D printing — all tailored for fast iteration and high-precision prototyping.

Latest Cases
Provide a short summary of our recent projects, From an idea to new product.
Optical LGP :PMMA vs. PC Prototypes
A European CMF display team needed high-clarity light guide plate (LGP) samples to test edge lighting and flatness.
We provided:
Materials: PMMA & PC
Process: CNC + 3-step hand polishing
Size: 210×150×5 mm | Tolerance: ±0.05 mm
Lead time: 5 working days
EV Charger ：CNC Machining VS Vacuum Casting
An EV charger company needed to validate enclosure design before tooling. We provided two parallel solutions:
CNC Machining: ±0.05 mm precision, used for mechanical testing and fit verification
Vacuum Casting: PU resin parts with realistic finish, ideal for demos and early feedback
By combining both, the team validated structure and appearance in under 2 weeks — accelerating their design freeze and reducing risk.
AI Vision ：From Concept To product
This case study shows how an AI sports hardware startup, validated three strap enclosure designs in just 6 days using our rapid prototyping and low-volume tooling services.
By combining CNC ,3Dpritining, vacuum casting, and fast DFM iterations, we helped the client accelerate their product validation cycle and get ready for user testing — fast.
dual-screen POS tablet housing, featuring a PVC touch monitor shell and integrated I/O bezel.
Within 6 days, we delivered CNC + vacuum cast parts with full cosmetic finishing — enabling live demo use in malls and franchise stores.
