Highlights of process difficulties:
1. Challenges of pure machining of tiny parts
As a tiny part, this product adopts pure machining process, which is a major challenge in itself. The processing of tiny parts requires extremely high precision and meticulous operation, which places strict requirements on the performance of processing equipment and the technical level of operators. Every processing step must be accurate and correct, and a slight deviation may result in unqualified products. Pure machining within such a small size range requires overcoming many technical difficulties to ensure the dimensional accuracy, shape accuracy and surface effect of the product.

2. Difficulties and highlights of the combination of brass material and real gold plating
The use of brass material to plate 18K real gold not only reflects the high quality of the product, but also increases its beauty and value. Of course, this process combination also brings many difficulties. First of all, it is required to ensure that the surface finish of the contact reaches RA0.2 or less before plating, which requires precise processing technology and strict quality control. Secondly, the thickness of the real gold layer is greater than 5 microns and requires high wear resistance, which requires precise control of the gold plating process to ensure that the uniformity and thickness of the gold layer meet the requirements. At the same time, the bonding strength between the gold layer and the brass material must also be considered to ensure that the gold layer does not fall off during use. The high wear resistance requirement increases the difficulty of the process. It is necessary to select appropriate gold-plating materials and processes to improve the hardness and wear resistance of the gold layer. By overcoming the challenges of processing tiny parts, we have demonstrated our superb craftsmanship and our persistent pursuit of quality.
