= What is Investment Casting? =

Investment casting is also known as ‘lost wax’ process and is also one of the oldest known metal casting methods where molten metal is poured into a mould. Investment casting dates back to 5000 years and can be traced back to Ancient Egypt and China, where patterns were formed out of beeswax to create jewellery or other ornaments. Today, high-technology waxes, refractory materials and a large range of alloys are used.

* Ensures parts have smooth surfaces with no parting lines.
* A vast range of alloys can be used, including carbon steel, stainless steel and those of aluminium and bronze. Materials that are difficult to machine can be used in this process too.
* Investment casting offers good dimensional accuracy to components.
* Clients can choose both low and high-volume manufacturing.
* Cost of production is reduced, since both assembly and waste are minimal.
* It’s possible to add names, logos or other information to the parts.
* Parts have a high level of accuracy, repeatability and integrity.

= When to Use Investment Casting? =

This process is popular worldwide when it comes to manufacturing parts with high accuracy, repeatability and cast integrity. It’s applied in a variety of industries and sectors, from oil and gas to automotive, aerospace and defence.

The investment casting process can be used:

* When clients require medium to high-volume of orders – virtually no tool wear, so it’s ideal for consistency and repeatability. The process also saves time and labour costs, since it eliminates the need for secondary machining.
* When high precision parts are required – investment casting allows for a great degree of precision, as well as great dimensional accuracy, complex shapes and the addition of details.
* When clients need different sizes – the process allows for the creation of parts that meet the demanding standards of a multitude of industries. These standards include size. Investment casting produces parts that can weigh a few grams up to several kilos.
* When there’s a need for a variety of materials – with investment casting, parts can be cast in both ferrous and non-ferrous metals, as well as an array of alloys.
* When parts need to have smooth surface finishes – investment casting is a process that allows for the manufacturing of components with finer quality finishes, as it can achieve near net shapes with little to no machining.
