ADDITIONAL SERVICES

In the world of high-precision manufacturing, chemical etching is often the "magic" that allows for incredibly intricate designs without the stress of mechanical stamping. But a raw etched part is often just the beginning.

​

To transform a flat metal sheet into a high-performance industrial component, you need a suite of specialized finishing services. We provide an end-to-end solution—from the initial etch to the final surface treatment—ensuring your components are ready for immediate integration.

​

1. Precision Forming & Assembly

 

Chemical etching starts with flat sheets, but your projects often live in three dimensions. We bridge that gap with Precision Forming.

​

• Smart Bending: Where possible, we etch "bend lines" directly into your parts. This allows for precise folding without the need for expensive, hard form tooling.

• Manual & Semi-Automatic Forming: We utilize modular and custom tools to achieve exact angles and shapes.

• Spot Welding: For 3D components that need to be permanently joined, our in-house spot welding ensures structural integrity.

 

2. Surface Enhancement: Passivation & Electropolishing

 

Metal longevity depends on how the surface interacts with its environment. We offer two primary ways to protect your parts:

​

• Passivation: This process purifies the surface and creates a protective oxide layer. It’s "invisible" protection—it doesn’t change how the part looks or its dimensions, but it significantly boosts corrosion resistance.

• Electropolishing: Think of this as "super-cleaning." It removes the outer microscopic layer of the metal, reducing roughness by up to 50% and making the surface incredibly bright and smooth. It offers up to 30 times the corrosion resistance of standard passivation.

​

3. Heat Treatment: Strengthening the Core

 

Sometimes the metal needs to be tougher, softer, or more flexible than its raw state. We offer four key heat treatment paths:

​

• Hardening & Tempering: To increase surface durability and strength.

• Annealing & Normalizing: To improve ductility and relieve internal stresses, making the part easier to work with.

4. Specialized Surface Finishing

 

To ensure your component functions perfectly in its specific environment—whether that's underwater, in a vacuum, or inside an engine—we provide:

​

• Anodizing & Electroplating: For electrical conductivity or wear resistance.

• Vapor Blasting: For a uniform, matte finish.

• Chemical Blacking & Chromium Nitride: For specialized aesthetic and high-friction applications.

​

5. Advanced Joining & Precision Cutting

 

When your design requires bonding multiple parts or hitting "impossible" tolerances, we use these high-end techniques:

​

Diffusion Bonding & Brazing

 

If you need to join two or more components:

​

• Brazing: Great for joining different types of metals or complex shapes using a filler material.

• Diffusion Bonding: This creates a "homogenous" bond—essentially turning two parts into one solid piece that can survive extreme vibrations and heat.

 

Wire EDM (Spark Erosion)

 

When chemical etching meets its physical limits, Wire Electro Discharge Machining (WEDM) takes over. By using an electric current and a microscopic wire, we can achieve profile accuracies of ±0.005 mm. This is the gold standard for parts that require zero residual stress and absolute precision.
