Tasso has more than 50 years of expertise in production of cast iron bars by the horizontal continuous casting process.
The profiles are available in round, square and rectangular shapes in a variety of dimensions. Tasso cast iron bars are manufactured in grey cast iron (GJL) and nodular cast iron (GJS, also known as SG, ductile or spheroidal graphite cast iron).
|
|
The process of continuous casting results in a fine-grained, dense microstructure of the bars and top quality surface finish. These properties result in a number of advantages in durability, performance and cost saving:
- Uniform structure free from shrinkage, gasholes, sand and other tool-wearing inclusions
- Excellent mechanical strength and corrosion resistance
- Damping of mechanical vibrations
- High level of machinability that allows precision machining
|
Tasso cast iron bars are ideal for manufacturing of hydraulic and pump components.
Tasso cast iron bars can also be used for production of items like pulleys for V-belts, gear wheels, rings, flanges, covers, valve linings, glass moulds, die-casting moulds, patterns, core boxes and bushings.
Tasso cast iron bars are available in a variety of grades which makes it possible for you to choose the optimal matrix and mechanical properties for your final product.
