What is nano injection molding process?

Nano Injection Molding Technology, known as NMT, revolutionizes manufacturing by treating metal surfaces at the nano level before injecting plastic directly onto them. This innovative process ensures robust bonding between plastic and metal, achieving seamless integration. With NMT, products can retain the metallic appearance texture while streamlining design complexities, resulting in lighter, thinner, and more compact products.


Advantages of NMT Nano Injection Molding Process

The NMT nano-injection molding process offers a multitude of benefits, transcending conventional manufacturing limitations. It not only preserves the metallic appearance texture but also streamlines product design, resulting in lighter, thinner, shorter, and smaller products—a feat previously deemed unattainable.

With enhanced design freedom, product concepts can flourish, alleviating design constraints and fostering innovation. Moreover, the process simplification eliminates the need for secondary processing steps, reducing complexities and saving time.

By consolidating multiple procedures into a single injection molding process, production cycles are significantly shortened, expediting time-to-market. Furthermore, the integration of metal and plastic at the nano level enhances mechanical strength, unlocking new application possibilities.

The overall cost advantage of NMT stems from reduced processing time, simplified procedures, and decreased complexity, ultimately enhancing product competitiveness in the market.

NMT Nano Injection Molding Process

The nano injection molding process prioritizes metal material processing at the nanoscale, serving as a cornerstone for the entire injection molding procedure. The process comprises several crucial steps:

  1. Degreasing: Immerse the metal workpiece in an alkaline solution for approximately 1 minute to remove surface grease.

  2. Neutralization: After alkaline treatment, neutralize the workpiece with acid to restore a neutral pH level.

  3. Nano Treatment: Apply T-liquid to the work surface, inducing the formation of a rough concave surface with diameters ranging from 3 to 20 nanometers.

  4. Nano Concave E Treatment: Further treat the concave surface with E treatment to enhance irregular surface roughness.

  5. Cleaning Treatment: Thoroughly clean the treated material with pure water to remove residual contaminants.

  6. Drying Treatment: Dry the metal parts to eliminate residual water and other substances from the surface, preparing them for subsequent processing.

  7. Injection Molding: Utilize the nano-sized surface to inject resin into the pits, facilitating the formation of a close bond structure between the resin and metal, thereby completing the injection molding process.

Special features of NMT nano injection molding process

Insert injection molding serves to interconnect metal and resin components through the following steps:

  • Utilization of T-treatment technology to create nano-scale pits on the metal surface.

  • Injection molding of hard resin into these nano-scale pits to establish a robust bond between the resin and metal.

  • Facilitation of lightweight external metal parts for the framework and chassis of newly developed products.

Suitable metal and resin materials for this process encompass a range of options:

  • Metals: Aluminum, magnesium, copper, stainless steel, titanium, iron, galvanized sheet, brass. Aluminum alloys, spanning from the 1000 to 7000 series, exhibit enhanced adaptability.

  • Resins: PPS, PBT, PA6, PA66, PPA. Notably, PPS demonstrates exceptional bonding strength, reaching up to 3000N/c㎡.


NMT technology contributes to mitigating environmental impact through several avenues:

  • Streamlined manufacturing processes and shortened production cycles.

  • Elimination of unnecessary surface treatment steps, particularly notable for glued magnesium alloy metals.

  • Embracing NMT as a safe and recyclable technology, further minimizing environmental footprint.

Application of NMT Nano Injection Molding Process

With increasing demands for 3C electronic products, the NMT nano-injection molding process emerges as an ideal solution, widely embraced in high-end consumer goods to elevate user experience and product quality. Its applications span across diverse sectors, including cell phone shells, computer monitors, automotive control panels, lighting embellishments, and various 3C electronic product designs.

Advantages of insert injection molding over die-casting are notable:

  • Utilization of injection molding tabs and ribs, enhancing the strength of products.

  • Production of thinner, lighter components at reduced costs.

Additionally, inserts offer versatility in surface treatment, including options such as aluminum alloy anodizing, brushing with spraying, high-temperature baking paint, electroplating, sputtering, and polishing.

Metal joining, as opposed to welding, brings several benefits:

  • Streamlined joining cycles, especially for complex 3D shapes.

  • Improved processability and reduction in product dead weight.

Injection molding presents its own set of advantages, including reduced weight, thickness, costs, and prolonged service life.

In conclusion, the NMT nano-injection molding process streamlines manufacturing, reduces the need for excessive surface treatments in glued alloy metals, and importantly, remains environmentally conscious as a safe and recyclable technology. Its versatility and eco-friendliness make it a favored choice across contemporary manufacturing industries.
