Gold-plated spring

Gold-plated spring refers to the spring which is coated with a layer of metal gold or alloy gold on the surface of the spring by chemical or physical methods. This treatment can significantly improve the performance and appearance of the spring, and is widely used in many fields.

Features of gold-plated spring:

Improve wear resistance and corrosion resistance: the gold coating can effectively isolate air and moisture, reduce the oxidation and corrosion of the spring, thereby extending its service life.
Enhance electrical conductivity: the gold coating can significantly improve the conductivity of the spring, which is particularly important for application scenarios that require good electrical conductivity.
Improve the beauty: the appearance of the gold-plated spring is more beautiful, with a noble and elegant texture, which can improve the overall grade of the product.

Gold-plated spring production method:

The commonly used spring gold-plating methods include chemical gold-plating, electroplating and vacuum evaporation. Each of these methods has its own advantages and disadvantages and is suitable for different application scenarios and requirements.
Chemical gold plating method: the thickness of the coating is thin, and a fine and uniform coating can be formed, which is suitable for occasions where the thickness of the coating is not high.
Electroplating method: the coating cost is higher, but the thickness is thicker, the quality of the coating is stable, and it is suitable for occasions with higher requirements for the thickness and quality of the coating.
Vacuum evaporation method: suitable for high-precision and small-batch metal coating, to ensure the uniformity and quality of the coating.

Application field of gold-plated spring:

High-end watches: The gold-plated treatment of the spring is a common treatment method on high-end watches, which can improve the texture and level of the table.
Electronic products: In electronic products, gold-plated springs can improve corrosion resistance and conductivity, thereby extending product stability and life.
Aerospace equipment: the gold-plated treatment of the spring can improve its corrosion resistance and oxidation resistance to meet the special use environment and performance requirements.
Furniture accessories: gold-plated spring can make furniture accessories more texture, enhance the grade and artistic sense of the product.
Other fields: such as automotive parts, pressure sensors, children’s toy models, medical equipment and other fields, gold-plated springs also play an important role.

Is the cost of gold-plated spring high?

The cost of gold-plated springs is indeed higher than that of ordinary springs, mainly due to the following factors:

The cost of gold-plated materials: the gold-plated materials used in gold-plated springs, such as real gold, gold-plated copper or gold-plated silver, etc., the price itself is better than that of ordinary spring materials, especially when real gold is used for plating, the cost will increase significantly.
Gold plating process cost: gold plating process includes chemical gold plating, electric gold plating and vacuum evaporation method, etc. The cost and technical difficulty of these processes vary. For example, the electroplating method can achieve a thicker coating, but its cost is also relatively high, while the chemical gold plating method, although the cost is lower, may not be suitable for all types of springs. The vacuum evaporation rule is suitable for high-precision and small-batch metal coating, but its equipment and process requirements are also high, which increases the cost.
Spring specification and shape: The specification, size and shape of the spring will also affect the cost of gold plating. In general, the larger the size and the complex shape balance of the spring, its gold plating cost will also increase accordingly. This is because the gold plating process requires more materials and more complex processes to ensure the uniformity and quality of the coating.
Market demand and supply: Market demand is also an important factor affecting the cost of gold-plated springs. When the market demand is strong, the price of gold-plated materials and gold-plated processes may rise, pushing up the cost of gold-plated springs. On the contrary, when the market demand is insufficient, the cost may be relatively reduced, but this is rare.

As one of the key technologies to improve the performance of the spring, the market demand for spring gold-plating has also expanded, especially in the fields of high-end electronic products, precision instruments and medical equipment, and spring gold-plating processing services are indispensable.
