Core Applications of Four-Column Single-Action Hydraulic Presses in the Gold Jewelry Industry

Four-column single-action hydraulic presses play a crucial role in the gold jewelry manufacturing industry. They are primarily used for pressing and creating jewelry molds, which is the most important and classic application of four-column single-action hydraulic presses in the gold jewelry field. Below, Jianlong Hydraulic Technology will briefly share some information:

1. Concept:

1.1 Utilizing the immense pressure generated by the hydraulic press, a flat, annealed gold sheet (usually 999 gold or K gold) is pressed between a steel mold engraved with an intricate pattern.

1.2 The mold typically consists of an upper mold (male mold) and a lower mold (female mold), which together form a closed cavity when closed.

2. Process Flow:

2.1 Material Preparation: Gold is rolled into sheets of the required thickness using a rolling mill and then annealed to soften it.

2.2 Mold Placement: The gold sheet is precisely placed on the lower mold.

2.3 Imprinting: The hydraulic press is activated, and the moving beam drives the upper mold downwards, applying immense and continuous pressure (usually with pressure holding).

2.4 Shaping: Under pressure, the gold sheet undergoes plastic deformation, filling every detail of the mold, thus clearly replicating all the patterns, designs, and even extremely fine textures (such as hairline or scales) on the gold sheet.

2.5 Removal and Finishing: After imprinting, the workpiece is removed and then subjected to subsequent processing such as trimming, polishing, and welding of other components (such as clasps).

3. Examples of Finished Products:

3.1 Pendants/Pendants: Gold pendants of various shapes, zodiac pendants, Buddha statues, nameplates, etc. Complex relief effects can be imprinted in one go.

3.2 Ring Bands: The patterns on the surface of many ring bands (such as twisted rope patterns, a combination of polished and sandblasted surfaces) are achieved through imprinting.

3.3 Bangle Accessories: Decorative pieces on bangles.

3.4 Coins/Commemorative Coins: Manufacturing of gold commemorative coins or antique-style gold coins.

In the gold jewelry industry, the four-column single-action hydraulic press is an indispensable "pattern reproduction expert." It perfectly combines industrial efficiency and precision with artistic refinement and beauty, making it possible to mass-produce gold jewelry with complex reliefs and exquisite patterns. It is one of the key pieces of equipment driving gold jewelry from luxury goods to the mass market and high-end products.
