Gold Coin Casting Solution-Yihui Casting-Jewellery Casting Machine

Yihui Casting | Gold Coin Fully Automated Standardized Mass Production Solution

Since its establishment in 2003, Yihui Casting has been deeply engaged in the fields of precision forming and hydraulic casting of precious metals for 23 years. Relying on independently developed fully automatic hydraulic and stamping core technologies and intelligent equipment throughout the entire process, Yihui Casting has created a high-precision, full process, fully automatic, and high safety one-stop standardized mass production solution for the pain points and process requirements of large gold coin factories. The solution focuses on fully automatic hydraulic forming, covering the entire production chain of gold coins from precious metal raw material inspection to finished product packaging. It perfectly adapts to the production of investment gold coins, legal commemorative coins, collectible gold coins, precious metal commemorative medals and other categories, and can achieve large-scale production with a weight accuracy of ± 0.001g and a surface smoothness of nanometer level. It completely solves the core pain points of the gold coin manufacturing industry, helps large gold coin production factories achieve automation, standardization and safety industrial upgrading, and sets a quality benchmark in the field of precious metal coinage.

With the continuous warming of the global precious metal investment market and the explosive growth of the legal commemorative coins, collectible gold coins, and cultural tourism IP commemorative medals markets in various countries, the gold coin manufacturing industry has ushered in new development opportunities. According to the 2025 Global Precious Metal Commemorative Coin and Investment Coin Industry Report, the annual trading volume of global investment coins has exceeded 200 billion yuan, with mainstream categories such as Chinese Panda coins, German Philharmonic coins, and American Eagle Ocean coins growing at an annual rate of over 18%. The market has put forward extreme requirements for the weight accuracy, pattern restoration, surface mirror effect, anti-counterfeiting technology, and mass production consistency of gold coins.

However, the vast majority of gold coin production factories still remain in the traditional mode of manual loading and unloading, single machine step-by-step production, and manual quality control, facing six core pain points: low production efficiency, prominent safety operation hazards, difficult control of product accuracy, substandard surface smoothness of gold coins, poor consistency in mass production, and high dependence on manual labor. Especially for large-scale gold coin production factories, the traditional mode can no longer meet the precision requirements of legal tender level and the mass production needs of 10000 tons, while facing strict pressure on safety production and compliance supervision.

Core pain points in the gold coin manufacturing industry

dimension	core pain point	Concrete pain points and business impact
Management decision-making level	Capacity for large-scale mass production is seriously insufficient, and the ability to undertake orders is limited	Traditional manual mode has a maximum daily production capacity of 50000 pieces per production line, and the delivery cycle of 500000 investment gold coin orders exceeds 30 days, making it impossible to produce continuously 24 hours a day. Faced with large-scale orders of tens of thousands of tons, it is completely unable to undertake them, missing out on market dividends.
	High loss of precious metal raw materials and uncontrolled production costs	Maximum weight tolerance caused by manual operation is ± 0.01g, and the industry average raw material loss is 1.2%. Calculated based on a golden monthly processing volume of 1 ton, the monthly raw material loss exceeds 4 million yuan; The qualified rate of finished products is only 82% -85%, and rework and scrapping further increase operating costs.
	Excessive dependence on manual labor, high labor costs and management risks	Entire process relies on the experience of senior technicians, with a high proportion of workers and labor costs accounting for over 55% of the factory's operating costs; Personnel turnover directly leads to production interruption, quality fluctuations, and complete limitations on factory scale expansion.
Production Execution Layer	Poor product accuracy and quality stability, lack of ability to handle high-end orders	Manual adjustment of the machine leads to uneven tablet thickness, deviation in punching weight, and misalignment of hydraulic forming. Manual polishing is prone to scratches, pockmarks, and water ripples. The restoration of relief patterns and anti-counterfeiting patterns is insufficient, which cannot meet the quality requirements of legal commemorative coins and high-end collectible coins. The product's premium ability and market competitiveness are seriously insufficient
Production Execution Layer	Batch consistency cannot be guaranteed, posing compliance risks	There are significant deviations in weight, size, surface effect, and pattern clarity of gold coins produced by different operators and batches. There is no unified standard for quality control, and there is even a risk of compliance penalties for batch deviations of legal commemorative coins.
Compliance and risk control layer	Manual operation in high-risk areas poses significant safety hazards in production	Stamping, hydraulic pressure, and high-temperature annealing processes are all high-pressure/high-temperature heavy equipment, and manual loading and unloading modes are prone to safety accidents such as crushing, squeezing, and scalding. They face strict supervision and shutdown rectification risks from safety supervision departments, and the cost of factory safety production management remains high.
Compliance and risk control layer	Production line links are scattered without a closed loop, and the full process control is ineffective	Most of the equipment is purchased individually and sporadically, with mismatched processes and multiple interruptions in the workflow. The raw cake and semi-finished products are prone to wear and tear during circulation; Multi link decentralized management requires a large number of quality control and circulation personnel, and the management cost remains high, making it impossible to achieve full process traceability and control.
