CAD/CAM Developed Propeller styles are designed and new patterns
are produced using the latest CAD /CAM computer technology.

|
Pattern Making For greater accuracy our propeller castings are made
from "full" metal patterns, not indexed from single blade wooden patterns.

Moulding
Most propeller moulds are made from a special resin sand which forms a rigid
two part
mould ensuring more accurate and sound castings.
|
Casting Only Premium grade metals are used in the
manufacture of Austral propellers. Each metal batch is independently certified to
conform to alloy specification before delivery to our premises. |
 Casting - Large Propeller

Casting - Small Propellers |
 Machining - Flat Bed Lathe

 Machining - Electronic Lathe
|
Machining
A variety of CNC machines and specialised boring, facing and electronic
lathes are used to accurately machine Austral propellers.
|
Pitching Austral uses PropScan®
pitch
verification measurement equipment during the manufacturing process to
ensure pitch accuracy conforms to ISO class tolerances at pre-determined
radii across the blade face. |

 Hand Finishing
|
Finishing The propeller castings are then ground
on various special purpose abrasive machines. |
| Balancing
For smoothness, propellers are firstly static balanced then finally
electronically balanced on a computerised balance machine. Dynamic balancing
is also available.

Quality
Control During manufacture and upon completion, each propeller is
individually checked for accuracy of track, diameter, pitch, balance, blade form and
finish. Manufacturing details of each custom made propeller are recorded for
future reference. |
|
Shipping Worldwide Austral propellers are now
exported to over 40 countries worldwide. Austral produces high quality
marine propellers at very competitive prices within particularly short
manufacturing lead times. |
