Main Applications of a 300-ton Hydraulic Press for Stamping Gold Jewelry

The 300-ton hydraulic press for stamping gold jewelry, often referred to as a "sheet press" or "stamping press" in jewelry processing plants, is used throughout the entire jewelry manufacturing process and is central to achieving standardized, mass-produced production. Its main applications can be summarized into the following three areas. See the sharing by the Jianlong Hydraulic Technology editor.

1. Basic Material Preparation: Rolling (Core Application)

This is the most basic and important function of this equipment, transforming irregular gold material into standardized semi-finished sheets/strips.

1.1 Process: Gold bars or nuggets, after smelting and casting, are repeatedly rolled in two or more passes under the powerful pressure of a hydraulic press, gradually reducing their thickness. The result is gold sheets or strips of uniform thickness and precise dimensions.

1.2 Outputs:

1.2.1 Sheets of varying thickness: Used for pendants, plaques, bracelets, etc.

1.2.2 Strips of Different Widths: Used to make rings, chain links, bracelet bands, etc.

1.3 Importance: This serves as the foundation for all subsequent precision processing, such as stamping and lathing. The accuracy of material thickness and uniformity directly determines the quality and cost of the final product.

2. Semi-finished Product Texture Processing: Relief and Pattern Stamping

After obtaining a flat gold sheet, this hydraulic press can be used to directly stamp a three-dimensional pattern onto its surface.

2.1 Process: A set of matching yin and yang molds is used, one side of which is engraved with a designed pattern (such as a pattern, texture, brand logo, zodiac image, etc.). When the hydraulic press applies pressure, the mold pattern is precisely "transferred" to the surface of the gold sheet.

2.2 Outputs:

2.2.1 Gold sheet with embossed patterns: Used to create antique gold, embossed pendants, and plaques.

2.2.2 Substrates with special textures, such as fabric and brushed patterns: Provide unique visual effects for jewelry. 2.3 Advantages: Efficiently complete large-area texture processing in a single operation, with clear and consistent patterns, far surpassing the capabilities of hand engraving.

3. Initial Product Forming: Punching and Bulk Forming

Using dies, blanks with specific shapes can be directly produced from gold sheets, or thick stock can be initially shaped.

3.1 Punching (Cutting)

3.3.1 Process: Using a sharp punching die, like a "cookie cutter," gold sheets are punched into specific flat shapes.

3.3.2 Outputs:

■ Ring Blanks: Rectangular gold bars for subsequent rounding into rings.

■ Hangtag/Pendant Blanks: Simple shapes such as round, oval, and heart-shaped.

■ Link Blanks: Individual links used to create specific necklace styles. 

3.2 Bulk Forming

3.2.1 Process: For thicker gold materials (such as blanks for solid bracelets or ring arms), a hydraulic press is used for initial forging and shaping, essentially resembling the final product's outline and volume.

3.2.2 Output: Solid jewelry blanks, significantly reducing the workload of subsequent manual polishing and forming.

In summary, the 300-ton gold jewelry stamping hydraulic press primarily covers the critical conversion steps from "raw material" to "semi-finished product." It is not only an efficient production tool but also a key piece of equipment for ensuring consistent product quality, controlling material loss, and enabling complex designs. It is an indispensable component of modern large-scale gold jewelry manufacturing.
