Complete production solutions for manufacturing high-quality gold and silver bars, covering melting, casting, forming and surface finishing processes.
Complete Gold & Silver Bar Production Solutions
Juyi provides complete manufacturing solutions for gold and silver bars, integrating melting, casting, forming and branding processes into one streamlined production system.
From precious metal melting and vacuum casting to precision logo stamping and surface finishing, we help bullion manufacturers produce bars with consistent weight, excellent surface quality and reliable identification.
Challenges in Gold & Silver Bar Casting
Producing high-quality gold and silver bars requires precise control throughout melting, casting and finishing processes. Traditional production methods often face challenges that affect efficiency and product quality.
Oxidation & Material Loss
Maintaining precious metal purity during melting and casting is critical.
Inconsistent Bar Quality
Uneven casting conditions can lead to weight deviation, internal defects and unstable quality.
Complex Production Processes
Separate melting, casting and forming operations increase handling steps and production complexity.
Product Authentication Requirements
Modern bullion products require clear branding, serial numbers and secure identification.
Juyi Integrated Gold & Silver Bar Casting Solution
Juyi integrates vacuum gold and silver bar casting technology with automatic hydraulic stamping systems to create a complete production process from melting to final branding.
By performing melting and casting within a controlled vacuum chamber, the system minimizes oxidation, improves metal quality and ensures excellent casting consistency. Combined with precision hydraulic logo stamping, every bar achieves accurate weight, superior surface finish and reliable product identification.

Frequently Asked Questions — Gold Bar Casting Solutions
Gold bar casting involves melting pure gold or silver, pouring it into molds under vacuum or inert gas protection, cooling the bars, and finishing them with polishing or stamping for branding and authenticity.
Our casting machines support a wide range, typically from 100 g up to 10 kg bars. The most common are 1 kg, 5 kg, and 10 kg bullion for refineries and investment purposes.
The vacuum system prevents oxidation, reduces porosity, and ensures a smooth mirror-like surface on each gold or silver bar. It also minimizes metal loss during the process.
Yes. The gold bar logo stamping machine can imprint logos, weights, purity, and serial numbers with high precision, helping refiners and banks ensure brand identity and authenticity.
Besides gold, our machines also work with silver, platinum, palladium, and copper alloys, making them suitable for a wide range of precious metal applications.
We provide solutions for both. Small-capacity machines (1–2 kg) are ideal for workshops and labs, while larger systems (5–10 kg per batch or continuous casting) are designed for refineries and industrial-scale production.
With PID temperature control and precision molds, the weight deviation is kept within ±0.001%, ensuring compliance with international bullion standards.
We offer installation guidance, training, technical support, and spare parts supply. Our engineers can also provide customized solutions to meet specific production needs.
