ALUMINIUM ETCHING

In the world of precision manufacturing, finding a balance between intricate design, cost-efficiency, and material integrity is a constant challenge. Traditional methods like stamping or laser cutting often fall short when dealing with the unique quirks of aluminium.

​

At Metching, we have refined the art of aluminium etching, offering a highly repeatable and consistent process that serves as a superior alternative to conventional machining.

Why Etching Aluminium is a Science

 

Machining aluminium and its alloys has historically been a headache for manufacturers. Whether using traditional mechanical tools or standard chemical etching, aluminium presents two main hurdles:

​

1. Thermal Reaction: During the etching process, aluminium releases significant heat energy, which typically results in rough, granular edges.

2. High Reactivity: The metal is extremely sensitive to chemical agents, meaning even a slight deviation in the environment can ruin the precision of a part.

 

To solve this, we pioneered a robust, proprietary solution. Our specialized process manages the thermal energy and chemical reactivity to produce cleaner edge profiles with an accuracy and efficiency that standard methods simply cannot match.

​

Complex Geometries Without the "Complexity Cost"

 

One of the greatest advantages of our process is the use of low-cost digital tooling. In traditional stamping, a new design requires a physical die, which is expensive and time-consuming to produce.

​

With digital tooling, we can offer:

​

• Rapid Prototyping: Accelerate design iterations and reach the market faster.

• Zero Cost Penalty for Complexity: Whether your design is a simple square or an intricate web of channels, the cost remains the same.

• Extreme Precision: We achieve tight tolerances with accuracy down to $\pm 0.020\text{mm}$.

• Stress-Free Results: Unlike laser cutting, etching involves no heat-affected zones (HAZ), ensuring the material properties of the aluminium remain unaltered.

 

Versatility Across Grades and Alloys

 

Our expertise isn't limited to pure aluminium. We work with a vast spectrum of alloys and specialized materials to meet the demands of modern engineering:

​

• Standard Alloys: 3003, 5052, 6061, 7075

• Specialty Metals: Aluminium Bronze

• Flexible Tech: Aluminium Polyimide Film (ideal for flexible electronics)

​
