Series Of Titanium Casting Machine
Titanium is considered difficult metal to cast.
However, with an understanding of titanium's properties and the right casting machine, the fabrication of titanium products is within your grasp.
Reasons Why Titanium Casting Is Difficult
- 1. Easy to oxidize at high temperature
→ Should be melted in a high vacuum or inert gas - 2. Extremely high activity at high temperature
→ Very few molds and crucibles are available that do not react with molten titanium - 3. Light specific gravity
→ Insufficient casting pressure cannot be obtained. - 4. High melting point
→ Limited heat source for melting
Copper Crucibles To Reduce Running Costs
When casting by induction melting, ceramic crucibles such as calcia are used.
Although calcia is said to be less susceptible to contamination, it is expensive, and its running cost is high due to its tendency to crack when heated rapidly.
Our casting machines use copper crucibles to reduce crucible running costs.
Note : The copper crucible in this case is not a ordinal consumable material like, for example, carbon crucible or/and silica crucibles, but a kind of base on which a casting ingot is placed on.
Arc Melting Solves Contamination Problems
Titanium is very averse to contamination compared to other metals. It changes the composition and expected properties of titanium itself, so it is better to minimize this risk as much as possible to make titanium products.
Arc melting, which is adopted in our casting machines, can cast titanium products without touching other materials.
Melting Titanium In A Titanium Crucible
Melting of a disk-shaped titanium ingot is melted from the center outward using arc discharge, and casting is performed just before the ingot's outer circumference is completely melted, thereby preventing contamination caused by molten titanium coming in contact with other materials.
Centrifugal And Pressurized Methods Are Available
Two types of casting methods, centrifugal and pressure, are available depending on the shape of the product. We will propose the most suitable model for your desired product shape.
“Centrifugal Method” With High Casting Force
When casting thin objects or/and filigrees, the centrifugal method is recommended due to higher casting force than pressure method.
However, when products that multiple runners or ingates should be attached to casts or when casting annular shapes, the possibility of casting porosity due to turbulence caused by centrifugal force is high.

“Pressure Method” To Reduce The Occurrence Of Porosities
In case when the cast pieces are thick, annular or/and multiple runners or ingates are needed to be installed, a pressure casting machine can be expected to reduce problems of casting cavities compared to a centrifugal casting machine.
