50kg 380V High Vacuum Ingot Casting Machines For Gold Adjustable Heating Power
Compact High Vacuum Precious Metal Continuous Caster
1. Product Overview
The SSM-HVCM50 is a high-capacity compact high vacuum continuous casting equipment designed for high-purity precious metal production. It integrates high vacuum sealing melting, induction heating and down-draw continuous forming technology to effectively reduce oxidation, volatile loss and internal porosity during the casting process.
This model supports both high vacuum and ultra-high vacuum configurations, making it suitable for gold, silver, copper and various precious metal alloys. It can continuously produce rods, strips, tubes, plates and custom cross-section blanks with stable density and low impurity levels.
With a gold melting capacity of 50kg and adjustable heating power from 0 to 30KW, the SSM-HVCM50 is ideal for high-end refineries, dental alloy manufacturers, electronic material factories and precious metal processing enterprises that require strict purity control.
2. Key Advantages
✅
High Vacuum Protection for High-Purity Casting
Supports high vacuum (10⁻¹ ~ 10⁻⁵Pa) and ultra-high vacuum (<10⁻⁵Pa) options. The fully sealed melting chamber isolates oxygen, helping to reduce metal oxidation, volatile loss and surface contamination.
✅
50kg Gold Capacity with Adjustable Power
Offers a maximum gold melting capacity of 50kg with 0–30KW stepless adjustable heating power. It adapts well to different alloy formulas and production batch requirements.
✅
Stable Temperature Control for Consistent Quality
Equipped with a high-precision temperature control system to maintain a stable molten pool. This helps reduce alloy segregation, improves material density and ensures consistent casting results across batches.
✅
Multi-Profile Production in One Machine
By replacing different crystallizer molds, the machine can produce rods, strips, tubes, plates and custom-shaped blanks. It supports flexible production planning and reduces the need for additional equipment investment.
✅
Compact Integrated Structure
Designed with a compact footprint and integrated layout, the machine is easier to install and suitable for factories with limited workshop space.
✅
Factory Direct Supply, Ready Stock Available
As a professional precious metal processing equipment manufacturer, we offer factory direct pricing, reliable quality control and fast delivery. Standard models are available for immediate purchase.
✅
Customization, OEM & ODM Supported
We support custom vacuum configuration, power adjustment, mold design, equipment parameter optimization and OEM/ODM private labeling to meet different production requirements.
3. Working Principle
-
Sealed Feeding and Vacuum Pumping
Precious metal raw materials are placed into the crucible, and the chamber is fully sealed and evacuated to reach the required vacuum level before heating.
-
Induction Melting Under Vacuum
The high-frequency induction heating system rapidly melts the raw materials under vacuum atmosphere, forming a homogeneous molten pool with minimal oxidation.
-
Down-Draw Continuous Forming
Molten metal flows into the water-cooled crystallizer under gravity. The servo traction system pulls the solidified blank downward at a controlled speed, realizing continuous one-step forming.
-
Discharge and Downstream Connection
The continuously cast profiles are discharged at a fixed height and can be directly connected with rolling mills, wire drawing machines, cutting machines and other downstream equipment.
