United Cast Bar

Unibar offers significant advantages and is superior to many other materials and production methods, in cost savings, product, quality and inventory.

Machinability

The machinability of Unibar is improved over other materials, due to the presence of microscopic particles of graphite in the structure, which act as a lubricant.
In addition to this, the homogeneity of its structure and the absence of the abrasive inclusions of sand which are typical in sand casting, improve machinability and therefore
prolong the life of tools, drastically cutting costs.

· Unibar improved feeds and speeds 35-50%.
· Improved tool (insert) life up to 60%.
· Reduced torque, power requirements reduced up to 50% (Figure 2), Power used, kWh (Figure 1).
· Can be cut/machined dry eliminating expensive lubricants and coolants.
· Excellent surface finish after the machining processes.
· Avoidance of abortive machining costs.

Low Density

Low density hence 10% lighter than comparative steel products.

Availability

Availability of Unibar from comprehensive range of bar material stock in a wide range of sizes and grades, facilitating improved stock management reduced inventory and
improved control.

Patterns & Dies

Patterns and dies Unibar eliminates need for costly patterns and dies, no restriction on design or volume changes, resulting in lower overall costs and quicker deliveries,
when compared with alternative production processes.

Homogenous close grained Structure

Homogenous close grained structure gives excellent machinability, good wear resistance and ability to withstand hydraulic or pneumatic pressures.

Strength and Ductility

Strength and ductility in SG/Nodular iron comparable to most low alloy and free cutting steels.

Thermal Conductivity

Thermal conductivity Unibar is recommended for applications in which heat dissipation is the priority, since graphite is an excellent heat conductor.

Lower Residual Stress

Lower residual stress as the core of Unibar remains liquid, while the peripheryis solid at the moment the bar exits the die and cooling system,
means that, the bar undergoes a heat treatment, intrinsic to the process, from the inside to the outside of the bar, which releases the majority stresses in Unibar a product
of the Unibar process.

Improved Dimensional Stability

Improved dimensional stability Unibar has a high dimensional stability, a result of the low residual stresses formed during the slow unrestricted cooling, and the subsequent
annealing process. Ideal for applications, where machining is required and subject to high pressures.

Improved Wear Resistance

Improved wear resistance due to a self-lubricating network of graphite.

Excellent Bearing Properties

Excellent Dampening

Excellent dampening of both noise and vibration in flake and nodular, due to the graphite in the structure in Figure 3.

Improved Corrosion Resistance

Improved corrosion resistance Unibar offers high resistance to corrosion better than steel and as good in many cases as non-ferrous materials.

High Fatigue Strength

High fatigue strength Unibar is an ideal material for those applications in which higher levels of fatigue strength are required, due to the absence of defects, as well as
the cohesion of the structure compared to sand cast products.
