Consumer Electronic Connector Prototype
A tech startup needed functional prototypes for micro connectors with intricate internal holes and fasteners. We produced high-resolution resin 3D prints for plugging tests and sealing verification. Zero tooling cost and flexible design iterations allowed the client to finalize the optimal design before formal production.
Smart Home Housing (Rapid Injection)
A smart home brand launched a new product and ordered 300 housings for overseas market testing. We provided rapid low-volume injection molding with silk-screen printing and matte coating. Complete finished products were delivered in 18 days. Clients can test market responses at low risk before investing in expensive mass-production molds.
