Harrop Casting Technologies specialise in non-ferrous castings, where all aluminium products are in-house heat-treated and shot-peened. Harrop CT can also produce brass, copper and magnesium products for a variety of applications.

Local Fabrication Services

Harrop Casting Technologies is based in Adelaide, which means you reap all the added benefits of working with a local Australian business. Import costs, customs clearance, shipping delays and difficulties communicating with overseas suppliers are avoided. Additionally, for repeat supply using existing tooling and moulds, Harrop CT can produce your parts with significantly faster lead times (as little as a week) which makes a huge difference when parts are needed urgently.


Casting Capabilities

While Harrop CT specialises in aluminium castings, its abilities also extend to brass, copper and magnesium products. The company is quality accredited to ISO9001:2015, which covers all aspects of operation, manufacturing and distribution. Their range of parts include:

  •           Housings
  •           Brackets
  •           Supports Covers
  •           Pipes
  •           Tanks
  •           Manifolds
  •           Engine Parts
  •           Electric Motor Housings
  •           Street & Park Furniture
  •           Components for Rolling Stock


Not Just Automotive

Cast products and components are produced for a wide variety of industries from marine, military, industrial, aviation, manufacturing and engineering. Whether your cast part is only a few hundred grams or over a hundred kilograms, Harrop CT can provide it in either part-finished or fully-finished condition depending on the requirement. All steps in the process are available, comprising:

  •           Pattern making/tooling
  •           Moulding
  •           Melting and pouring
  •           Heat treatments
  •           Post cast finishing 

Harrop CT can also quote on production from your existing tooling or moulds. Our technical team will provide expert advice and assistance about optimal manufacturing and cost efficiency. Talk to one of our helpful staff to find out more.

 


Casting Methods

Some typical casting methods Harrop CT utilises are Gravity Die Casting, Sand Casting, Core Blowing and Shell Cores.

Gravity Die Casting uses permanent steel moulds with gravity filling for larger volume production runs. It is optimal for complex castings.

Sand Casting is better applied to lower volume production where die tooling costs cannot be justified. Sand moulds are created and bonded together using composites. Upon assembly the moulds are gravity filled and the sand is broken out after solidification.

Both Core Blowing and Shell Cores include resin covered sand to create a mould and is an expendable mould casting. In comparison to Sand Casting, it boasts better dimensional accuracy and higher productivity rates.

Additional production processes:

  •           Heat treatment – solution heat treatment to T6 and ageing
  •           Impregnation processes are available in-house to customers requiring pressure tightness and leak resistance in critical castings such as pumps and tanks
  •           Metrology is performed throughout the manufacturing process and includes an ARL Spectrograph
  •           Technical support for tooling/pattern design including gating, runners and raisers
