The Topsmelt jewelry casting machine (TPS-CM), also known as an automatic vacuum casting system, is designed for casting a wide range of precious metals from 1kg to 6kg.
Whether you’re working with gold, silver, copper, or other metal artworks, this machine delivers high-speed performance with excellent energy efficiency.
Engineered for precision casting, the Topsmelt vacuum jewelry casting machine ensures zero shrinkage, air holes, or density defects in the final product. Equipped with a pressurized inert gas chamber, it eliminates porosity and delivers smooth, flawless castings with a premium finish.
In addition, its powerful induction stirring system ensures a perfectly uniform metal alloy during the melting process—ideal for producing high-quality jewelry pieces with consistent structure and appearance.

The Topsmelt jewelry casting machine (TPS-CM) is equipped with an inbuilt PID (Proportional–Integral–Derivative) temperature controller, which automatically regulates the system once the operating parameters are set. This ensures precise and stable temperature control throughout the casting process.
The furnace can reach a maximum temperature of 1600°C in just a few minutes, with an impressive temperature accuracy of ±2°C, delivering consistent and high-quality results.
Powered by a 15kW induction generator, the machine is capable of melting precious metals and metal artworks within 3–5 minutes, greatly improving process efficiency while reducing downtime and operational costs.
To ensure safety, the system integrates multiple intelligent alarm functions that detect any abnormal operating conditions. The machine will automatically stop when issues such as overheating, system faults, or irregular parameters are detected—safeguarding both the operator and the equipment.
Compared to traditional models, the Topsmelt TPS-CM offers a larger working chamber, while still maintaining a compact overall footprint, making it ideal for workshops with limited space.
With vacuum pressure casting technology, this machine guarantees dense, smooth, and flawless final products, free from porosity or shrinkage defects.

How To Test The Purity Of Your Gold?
Jewelry casting equipment refers to machines and tools used to produce jewelry by melting metal and pouring it into molds. These devices ensure precise high-temperature melting and controlled pouring to create jewelry pieces with accurate shapes and consistent quality, widely applied in jewelry manufacturing processes.
Common types include vacuum casting machines, centrifugal casting machines, and continuous casting machines. Vacuum casting prevents porosity and oxidation; centrifugal casting uses centrifugal force to fill complex molds; continuous casting is suitable for mass production. Each type offers unique advantages to meet different manufacturing needs.
These machines can process various precious metals and alloys such as gold, silver, platinum, and palladium. The choice of material depends on the desired physical properties and design of the final product, with specific heating and process parameters required for different metals.
Yes, equipment is available in various sizes and capacities to meet the needs of both small artisan workshops and large-scale manufacturers, providing flexibility to accommodate different production scales.
Casting equipment offers precise dimensional control, high consistency, and the capability to reproduce intricate designs. Compared to traditional manual methods, mechanical casting improves production efficiency, reduces human error, and enhances product quality and competitiveness.
Operators must use appropriate protective gear, such as heat-resistant gloves and safety goggles, and strictly follow operational procedures and safety standards to prevent burns and other accidents due to high-temperature metal melting.
It is recommended to buy from reputable manufacturers and authorized suppliers, either through official websites or specialized distributors. Conduct thorough market research to select brands with mature technology and comprehensive after-sales support.
Although many machines are designed to be user-friendly, professional training helps improve safety and operational efficiency. Training typically covers equipment maintenance, process parameter adjustments, and troubleshooting.
Yes, modern casting equipment is versatile enough for both mass production and small-batch or bespoke jewelry, meeting diverse customer demands.
Regular maintenance includes cleaning machine components, calibrating sensors and control systems, and replacing worn parts promptly. Manufacturers usually provide detailed maintenance manuals to help prolong equipment lifespan and ensure stable production.
Yes, cast pieces generally require polishing to remove surface burrs and oxidation, improving surface finish.
