Nano-Injection Molding

What is Nano-injection Molding?
Nano-injection molding is a precision manufacturing process capable of replicating ultra-fine features and patterns (typically below 1 micron) on three-dimensional plastic parts. This advanced molding technique enables the creation of intricate microstructures and nanostructures directly on a polymer’s surface.
Nano-injection molding overcomes the resolution limitations of traditional injection molding and 3D printing. These patterned polymer components are used in various applications, including high-density microarrays for rapid medical diagnostics, precision microlens arrays for advanced optical systems, and complex microfluidic devices for lab-on-a-chip technology.
How Nano-Injection Molding Works
Our nano-injection molding process produces plastic components with micro and nanometer-scale patterned surfaces. This precision is achieved using mold inserts created with advanced techniques like:
Lithography
Plasma Etching
Laser Ablation
Electroforming
Micro-edm
These high-resolution inserts are made from durable hybrid nickel-steel and nickel-shim materials. The molded patterns significantly enhance our plastic products’ optical and mechanical properties. Additional functional and optical coatings can further improve the component performance.
