Investment Casting: Casting for Africa
Our Titanium Vacuum Investment Casting Capability is unique to the Southern Hemisphere, this technology enables the CSIR to cast Titanium and Nickel based alloys for high-end components. Additionally, semi-solid high pressure die casting (HPDC) produces high integrity Aluminium, Magnesium and Copper alloy components. This tech enables us to focus on highly specialised niche markets within the industry, future plans include adding additive manufacturing (3D printing) capability to become even more competitive.
New start up
The technology encompasses a full process chain, specifically 60-64 distinct processes aimed at casting reactive alloys into thin walled and complex shapes with high integrity. The reactive alloys we are capable of casting via these processes include Titanium, Aluminum, Magnesium as well as copper, Nickel and Cobalt based alloys. The local market is a niche market which seeks high-end, complex shaped, components for demanding applications. We are able to meet this need and provide an access point for local manufacturing industries and local foundries. This is a lucrative market as we are saving local industry the capital layout it would take to manufacture these cast products themselves, and they have the convenience of access to local designers and new lightweight metal technologies. The aim is to commercialize our process capability with the aid of industry partnerships. In the future, we want to add local additive manufacturing capability, with the aim of introducing it as the new way of thinking regarding titanium casting. As this process of casting titanium substrates is very complex and due to the growing need for finer detailed features on the substrate this is a growing market. Accessing this can be achieved using laser additive technology.
We provide a high-value manufacturing platform that enables local industry access to metal manufacturing technologies which has in the past been reserved for highly developed countries.
Using combinations of technologies in our platform makes it is possible to drive down costs of manufacture, enabling cost-effective, low-volume, customized, high-end manufacturing.
As far as we know, this facility is unique in the southern Hemisphere, and it will support the local development of vibrant downstream titanium and specialized alloy industries as an enabler to low-volume high-end manufacturing. Furthermore, the facility can also support the upstream Titanium Beneficiation Programme currently being developed under the DST in collaboration with National Government.
