Pressing coins requires the right hydraulic press tonnage based on coin size, metal hardness, and design depth. This guide explains how many tons are needed for different coin patterns and provides expert tips on selecting the ideal press for gold, silver, and copper coin production.
A hydraulic press machine uses hydraulic pressure to apply controlled force for metal forming, stamping, and embossing. In the precious metal industry, it is essential for producing gold and silver bars with logos, minting coins, and creating collectible bullion. Its high precision, consistent force, and versatility ensure uniform quality and efficient production in jewelry, minting, and industrial applications.
High-precision metal strip slitting converts wide metal coils into narrow, uniform strips, ensuring consistent quality, reducing waste, and improving downstream manufacturing efficiency. Juyi’s advanced slitting machines provide micron-level accuracy, burr-free edges, and high-speed operation for metals like gold, silver, copper, and aluminum.
Understanding the differences between metal strip slitting machines and cutting machines is essential for choosing the right equipment. Slitting machines specialize in dividing wide metal coils into precise narrow strips, making them ideal for industries requiring high material utilization and consistency. Cutting machines, on the other hand, focus on segmenting metal sheets into specific shapes or sizes, providing versatility for fabrication and custom production. Each machine has unique advantages depending on production needs, from efficiency to flexibility. Juyi offers advanced high-precision slitting and cutting equipment designed to deliver superior accuracy, durability, and performance for modern metal processing.
Gold wire drawing machines are essential equipment for producing high-quality, precise wires in jewelry, electronics, and industrial applications. Proper maintenance
Proper maintenance of metal strip slitting machines is essential for achieving precise cutting, high efficiency, and long-term reliability. Daily care includes checking blade sharpness, alignment, lubrication, and tension control. For long idle periods, machines should be cleaned, lubricated, and stored in a dry, covered environment to prevent corrosion. Common issues such as poor slitting quality, noise, vibration, or material jamming can often be resolved by adjusting blade alignment, tension, or replacing worn components. A preventive maintenance schedule—covering cleaning, lubrication, inspections, and professional servicing—helps extend machine lifespan and minimize downtime, ensuring consistent performance in jewelry, electronics, and industrial metal processing.
