Caswell Plating has revolutionized the electroplating industry with its high-quality DIY kits and extensive product range. Its contributions have made electroplating accessible for hobbyists and professionals alike.
History of Caswell Plating
Founded in 1990, Caswell Plating began by introducing a small Nickel Plating Kit designed for do-it-yourself enthusiasts. This kit was pivotal in making electroplating practical for home use. Over time, the company expanded its product line to include anodizing kits, metal polishing supplies, bronzing, and antiquing supplies.
Caswell also developed specialized products like the ethanol-resistant Gas Tank Sealer. With over 30 years in the industry, Caswell has continually revised its offerings to meet the evolving needs of its customers. Their plating manual has undergone multiple updates, making it an essential resource for small-scale plating.

Caswell also offers specialized products for unique applications, making them a one-stop shop for all plating needs. Their contributions have made them a respected name in the electroplating industry, consistently pushing the boundaries of what is possible in small-scale plating.
Caswell Plating Techniques
Caswell offers diverse methods for plating, each suitable for specific materials and project requirements. Here’s a detailed look into three primary techniques: electroplating, anodizing, and electroless plating.
Electroplating Fundamentals
Electroplating involves using an electric current to reduce dissolved metal cations so that they form a thin, coherent metal coating on an electrode. This technique is widely used for coating objects to prevent corrosion, enhance appearance, or reduce friction.
Caswell provides various kits, including quality plating kits, sealers, and accessories, to help achieve precise results. Key steps include cleaning the substrate, applying the plating solution, and then passing the electrical current through it. Essential to this process are thorough cleaning, constant monitoring of current and solution levels, and understanding the compatibility of different metals.
Anodizing Processes
Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, and corrosion-resistant finish. Unlike plating, anodizing changes the surface structure rather than adding a separate layer.
Caswell specializes in kits for aluminum anodizing which involves submerging the aluminum object in an acid electrolyte bath and passing an electric current through it. The anodized layer is integral to the metal, providing durability and aesthetic appeal. Attention to acid concentration, current density, and temperature control are critical for consistent results.
Electroless Plating
Electroless plating does not use electrical power but rather relies on a chemical reaction to deposit the metal. This method is ideal for coating non-conductive surfaces and achieving an even layer. Caswell’s electroless plating kits include items like activators and solution heaters to facilitate the process.
The key steps involve preparing the substrate, activating the surface, and submerging it in a plating solution where the metal is deposited through a chemical reduction. This technique ensures uniform coverage, even on complex shapes, and avoids issues related to electrical current distribution. Proper maintenance of the chemical bath is crucial for effective plating.
Types of Plating Solutions
Different plating solutions offered by Caswell Inc. vary in composition and application methods, making them suitable for specific metals and finishing requirements. This section covers some popular formulations.
Copper Formulations
Caswell Inc. provides diverse copper plating options, ideal for various industrial and decorative purposes. The Electroless Copper Solution is a notable product, requiring a two-part mixture labeled as Part A and Part B. Users mix equal parts of these with distilled water to create the solution. This type of copper plating does not need an electric current, making it easier for small-scale applications.
For those who prefer traditional methods, the acid-based copper plating solutions are also available. These solutions work well for building up the thickness of copper layers. They are often used before nickel or chrome plating to create a smoother surface.
Nickel Varieties
Nickel plating is widely used for its durability and corrosion resistance. Caswell Inc. offers several nickel solutions, including the One-Plate® Electroless Nickel Kit. This kit simplifies the process by using a single chemical concentrate mixed with distilled water. It operates at a temperature of 185°F and is straightforward to use, even for beginners.
The bright nickel plating solution is another option designed to provide a shiny, polished finish. It is particularly effective for automotive and hardware applications where aesthetics are crucial. Additionally, there is low deposit stress, ensuring the plated item retains its structural integrity.
Gold Solutions
Gold plating solutions from Caswell Inc. offer both decorative and functional benefits. The gold electroplating solutions are typically used for jewelry, electronics, and decorative items. These solutions produce a rich, yellow finish and excellent conductivity, making them ideal for electronic connectors and circuit boards.
In some cases, brush plating solutions are preferred for precision work. This allows the user to apply gold selectively using a brush, making it perfect for small areas or repairs. The brush plating method also conserves the amount of gold solution used, which is beneficial given the high cost of gold.
These formulations cater to various needs, ensuring the final product meets the desired appearance and functionality.
