Expert Removal for Re-Plating and Salvage

Metal Finishing Group provides specialized Metal Stripping services, precisely removing existing metallic coatings from various substrates. This process is essential for salvaging incorrectly plated parts, preparing components for re-plating with a fresh finish, or reclaiming valuable base materials. Our methods ensure the efficient removal of coatings while preserving the integrity of the underlying metal.

Metal stripping is chosen when components have a worn, defective, or incorrect coating that needs to be removed without damaging the part’s dimensions or surface. It is ideal for industries that require re-work, quality control, or material reclamation, providing a cost-effective alternative to scrapping valuable parts. Our expertise in chemical stripping ensures a clean, ready-to-process surface.

Our Metal Stripping Capabilities: Precision and Material Preservation

We offer precise Metal Stripping services, ensuring safe and effective removal of coatings for your components.

  • Selective Coating Removal: Our processes are designed to selectively remove the plated layer while minimizing impact on the base material.
  • Broad Coating Compatibility: We can strip a wide range of metallic coatings, including but not limited to:
    • Nickel (Electroless Nickel, Sulfamate Nickel, Bright Nickel)
    • Zinc
    • Cadmium
    • Copper
    • Silver
    • Gold
    • Chrome (decorative layers)
    • Other specialty coatings
  • Diverse Substrate Compatibility: We handle stripping from various base materials such as steel, stainless steel, brass, copper, and others, carefully selecting chemistries appropriate for each.
  • Dimensional Integrity: Methods are chosen to prevent significant dimensional changes or etching of the base metal, crucial for precision parts.
  • Preparation for Re-plating: Provides a clean, active surface, perfectly prepared for subsequent plating processes.
  • Salvage and Rework: Offers a cost-effective solution for salvaging expensive or complex components that have been incorrectly or defectively coated.
  • Environmentally Responsible: Our stripping processes are managed with environmental responsibility, including proper waste treatment and disposal.
  • Rack and Barrel Processing: We accommodate both rack and barrel stripping methods to suit various part sizes and production volumes.
  • In-house Quality Verification: We inspect stripped parts to ensure complete coating removal and surface readiness.

Properties of Effective Metal Stripping:

Effective metal stripping imparts several key properties that enable successful re-finishing and salvage:

  • Clean Surface: Leaves a surface free of residual coating, contaminates, and smut.
  • Dimensional Accuracy: Preserves the original dimensions and tolerances of the base material.
  • Surface Integrity: Avoids damage such as pitting, etching, or hydrogen embrittlement to the substrate.
  • Activated Surface: Prepares the base metal for optimal adhesion of new coatings.
  • Cost Efficiency: Provides a more economical alternative to manufacturing new components from scratch.

Applicable Specifications We Adhere To:

Our Metal Stripping processes are performed with careful consideration of relevant industry standards, ensuring the quality and readiness of your components for their next step. We often adhere to stripping practices that align with:

  • General industry best practices for surface preparation.
  • Customer-specific requirements for rework and re-plating procedures.
  • Specifications that define acceptable surface conditions for subsequent plating.

Typical Metal Stripping Applications:

Metal stripping is vital for numerous applications across various industries:

  • Quality Control Rework: Correcting parts that have been plated incorrectly or defectively.
  • Tooling and Fixtures: Removing worn coatings from tools, molds, and plating racks for re-use.
  • Restoration: Preparing antique or worn parts for re-plating to restore their original appearance and function.
  • Salvage Operations: Recovering expensive or difficult-to-manufacture components that would otherwise be scrapped.
  • Aerospace Maintenance: Stripping and re-plating critical components during overhaul and repair.
  • Prototype Development: Removing coatings from prototypes for modifications or re-testing.
  • Electronic Component Rework: Removing old finishes from electronic contacts for re-plating to improve conductivity or solderability.
