Precision Engineering / Casting Technologies
Harrop Casting Technologies specialise in non ferrous castings. In-house heat treatment and shot peening is applied to all our aluminium products. Continuous expansion in the die casting ﬁeld includes low pressure die casting of aluminium alloys and magnesium.
Harrop Casting Technologies is an Australian metal foundry based in Adelaide that specialise in Non Ferrous Metal Casting, including Aluminium Alloy, Brass and Copper. Traditionally the business has focused on Automotive OE and aftermarket parts, Defence and Industrial components. Flexible manufacturing methods allow production of either a single prototype or large quantities of complete castings from a few hundred grams to > 100kg.
Fast turn-around is available. Parts with existing tooling and typical manufacturing processes can be delivered in as little as 1 week.
PARTS WE CAST

The casting process is quite involved and uses the following steps, (for further information about the process, see here).
- Tooling Design
- Moulding Process
- Melting Process
- Heat Treatments
- After Casting Finishing
Harrop Casting Technologies is certified to ISO9001:2015 with a scope that includes the following:
The design/development, non-ferrous casting, manufacture, refurbishment and marketing of precision machined components and assemblies for automotive, motor racing, transport, military and general engineering applications.
Gravity Die Casting is the method used with permanent steel moulds with gravity filling for large volume production. This method is also ideal for complex castings.
Sand Casting is the method generally utilised for low volume castings where die tooling costs cannot be justified. It requires sand moulds to be created and bonded together using synthetic compounds, upon assembly the moulds are gravity filled and the sand broken out after solidification.
Core Blowing and Shell Cores is an expendable mould casting process that uses a resin covered sand to form the mould. As compared to sand casting, this process has better dimensional accuracy and higher productivity rates.
Additional Production Processes include:
- Heat Treatment - Solution Heat Treatment to T6 and Ageing.
- Impregnation processes is available in house to customers requiring pressure tightness and leak resistance in critical castings such as pumps and tanks.
- Machining Services are available - contact us for details.
- Metrology is performed throughout the manufacturing process and includes an ARL Spectrograph.
- File Information and Design Transfer is via Solidworks CAD by hard or soft copy transfer, or from a customer drawing.
- Pattern Making Services are available - contact us for details.
- Technical Support can be provided for Tooling/Pattern design including Gating, Runners and Raisers.
