How to Re-Chrome Plastic Parts?

Published in Plastic Plating 3 mins read

Re-chroming plastic parts requires a specialized process involving sending your parts to a plating company. This process is different from traditional metal chrome plating and involves several steps. Here's how it works:

Understanding the Process

Plastic, unlike metal, cannot be directly chrome-plated. Instead, it requires a series of preparatory layers to ensure the chrome adheres properly and provides a durable finish. The process is typically done by professional plating services.

Steps Involved in Re-Chroming Plastic

  1. Preparation: The plastic part is thoroughly cleaned and prepared to ensure proper adhesion of the subsequent layers.

  2. Nickel Coating: The plastic part is first coated with a layer of nickel. This is crucial because it helps with conductivity, which is necessary for the next plating steps.

  3. Copper Coating: A layer of copper is applied over the nickel coating. The copper layer helps provide a smooth base for the chrome and improves overall adhesion.

  4. Chrome Plating: Finally, a thin layer of chrome is applied on top of the copper layer. This final chrome layer provides the shiny, reflective finish.

Why Send Parts to a Professional Plating Company?

  • Specialized Equipment: Professional plating companies have the necessary specialized equipment for electroplating plastic, including baths, chemicals, and controlled environments.
  • Expertise: The process requires expertise in handling the chemicals, controlling the plating process, and ensuring optimal adhesion and finish.
  • Quality: Plating companies ensure high-quality results with durable and long-lasting chrome plating.

Summary

Step Purpose
Preparation Cleans part for proper adhesion of layers
Nickel Coat Provides conductivity
Copper Coat Provides smooth base for chrome and improved adhesion
Chrome Plating Provides shiny, reflective final finish

Additional Considerations

  • Cost: Re-chroming plastic parts can be more expensive than other finishing methods because it requires multiple steps and specialized equipment.
  • Turnaround Time: The time it takes to re-chrome plastic parts may vary, so it's essential to check with the plating service for estimated timelines.

Conclusion

To re-chrome plastic parts, you need to send them to a professional plating company that specializes in plating plastics. They will apply layers of nickel and copper before the final chrome finish.
