Chemical Etching Services in Singapore
Chemical etching, also known as chemical milling or industrial etching, is a subtractive manufacturing process that uses baths of temperature-regulated etching chemicals to remove material from a metal surface, creating an object with the desired shape. This process is commonly used in the manufacturing of precision parts and components for industrial purposes. Chemical etching is renowned for its ability to create parts that are highly complex and difficult to manufacture with traditional methods.

What is the Chemical Etching Process?
Chemical etching is a precise and versatile process used to selectively remove material from a metal surface using a chemical solution. Here’s a detailed look at each step involved in chemical etching.
1. Material Selection
The first step in the chemical etching process is to choose the right material. A wide range of metals can be chemically etched, including steel, stainless steel, copper and its alloys, nickel and its alloys, aluminium, and titanium. The metals can range in thickness from 0.010 mm to 1.5 mm and sheet sizes up to 600 mm x 1500 mm. The material selection will depend on your specific application requirements.
After the material is selected, it undergoes a rigorous cleaning process. This involves removing debris, waxes, and rolling oils that could interfere with the chemical etching process. The cleaning ensures that the metal surface is free from any contaminants that might affect the final result.
Once cleaned, a light-sensitive photoresist is laminated onto the metal sheet. This step is crucial for the precision of the finished product. Poor adhesion could lead to blemishes or inaccuracies during chemical etching, as it might allow the etchant to come into contact with areas of the metal that should remain protected.
In the next step of the chemical etching process, a photo-tool mask containing the desired design is prepared, and the laminated sheet is exposed to ultraviolet (UV) light. This transfers the component design onto the photoresist, which undergoes a chemical change upon exposure.
The sheet is then developed to remove the unexposed photoresist, revealing the raw metal where the etching will occur. The hardened areas of the resist will protect the metal during the chemical etching process.
6. Chemical Etching
Chemical etching agents, commonly using ferric chloride, are applied to the prepared metal sheet. Experts meticulously calculate the duration for which the sheet should be etched, considering factors like the kind of metal, its quality, thickness, and dimensions, as these elements influence the final outcome.
After chemical etching, the remaining photoresist is stripped away to unveil the finely etched components. This reveals the intricate designs that have been chemically etched into the metal.
8. Visual and Dimensional Inspection
After the chemical etching process is over, each component is subjected to rigorous visual and dimensional inspection using advanced optical inspection equipment to ensure that it meets the desired specifications.
Benefits of Chemical Etching
The following are the several benefits of using chemical etching as a manufacturing process:
Chemical etching is capable of producing intricate designs and tight tolerances due to the ability to selectively remove material from the metal sheets. This makes it ideal for creating high-quality precision components that require accuracy and repeatability.
Chemical etching is a highly efficient manufacturing process that can produce large quantities of precision components quickly and cost-effectively, without the need for expensive tooling. It is the perfect choice for those looking to increase production volume while reducing manufacturing costs.
Chemical etching’s versatility in working with a wide range of materials allows people to choose from a range of suitable materials for their specific application. This adaptability ensures there is no compromise on quality or accuracy, making it a popular choice for those looking to produce components that meet strict specifications and high-quality standards.
Which Materials Are Suitable for Chemical Etching?
At Million.com.sg, we offer chemical etching services on the following suitable materials:
Stainless steel is incredibly durable and highly resistant to corrosion, making it an excellent choice for chemical etching where other materials might not hold up. In addition, it has a uniform and consistent surface finish, ensuring precise and accurate results every time. Its ability to maintain its properties over time ensures that the etched pattern remains visible and unchanged.
Aluminium’s lightweight yet strong nature makes it an excellent choice for manufacturing that requires a high strength-to-weight ratio, while its non-magnetic and non-combustible characteristics make it a safe and effective material for chemical etching processes. Furthermore, aluminium’s malleability enables intricate and complex designs to be smoothly and accurately etched onto its surface, making it a versatile material for use in various industries.
Brass is an excellent material for chemical etching due to its high ductility and impressive machinability. Its unique golden appearance gives it an aesthetic edge over other materials, making it a popular choice for upscale applications or industries. Given its durability and resilience against wear and tear, brass is a preferred option for creating long-lasting and intricate designs.
It is important to note that the choice of chemical used for etching must be carefully considered to ensure that it is compatible with the material being etched.
