Engineering, Not Assembly
Machines designed in-house around measurable outcomes — lower metal loss, higher output and repeatable precision.
Vacuum Casting Machine Manufacturer
Vacuum casting machines that protect your metal.
We manufacture sealed vacuum casting systems for jewellery investment casting — engineered to remove porosity, reach fine detail and keep precious-metal loss to a minimum.

How vacuum casting improves quality
Casting under vacuum removes trapped air and gas from the melt and the flask cavity, eliminating porosity and misruns. As a vacuum casting machine manufacturer, we build systems that reach paper-thin sections cleanly and reproduce fine detail traditional casting cannot.
Reduce metal loss and defects
Sealed chambers and controlled pour temperature limit oxidation, keeping the lowest metal loss. Cleaner castings mean fewer rejects, less rework and higher yield from every pour.
Precision you can repeat
Digital PID control holds vacuum, temperature and timing to the same set-point on every cycle, so quality is consistent across operators and shifts.

Answers
Vacuum Casting Machine Manufacturer — FAQs
What is a vacuum casting machine?
A vacuum casting machine melts and pours metal under vacuum to remove air and gas, producing dense, detailed, porosity-free jewellery castings.
How does vacuum casting reduce defects?
By evacuating air from the melt and flask, vacuum casting eliminates gas porosity and incomplete fills — the most common causes of casting rejects.
What vacuum level do your machines reach?
Our standard systems reach around −759.98 mmHg for complete degassing and clean, thin-wall filling.
Are the machines suitable for export?
Yes. We supply and commission vacuum casting machines across 18 countries with voltage options and export documentation.
