Low Volume Castings

Low Volume Castings – Investment Casting

 

The need for high integrity, low volume castings is increasing in demand across ever wider markets. Whether its bespoke engineered castings or concept designs that need to be realised, Investment Casting has become the manufacturing route of choice for many. Advancements in technology allow low volume castings to be produced with extremely short lead times, and in combination with 3D printed wax patterns, greater design freedom and flexibility is achievable without being restricted by traditional manufacturing constraints.

Near-net-shape castings can be produced, with only minimal machining needed as the Investment Casting process does not require traditional draft angles to be considered. This low volume casting method does not require expensive tooling in order to produce the wax patterns, and in the case of the 3D printed wax pattern route, no tooling is required at all. This route is extremely cost-effective and allows wax pattern manufacture to be started immediately from a 3D CAD model and thus removes the extended lead time and cost of tooling. Therefore, Investment Casting is ideally suited to low volume casting manufacture.

If you wish to produce higher volume castings, rather than low volume castings, typically the die-casting manufacturing route has been preferred over others, especially if high integrity and repeatability is necessary. One major challenge of die-casting is the cost and lead time of the tooling, and it is usually only economical if the production volumes are large enough. Once tooling is produced, it can be difficult to optimise or modify if the casting design undergoes revision.

Did you know that the low volume castings method Investment Casting, can also be used to supplement die-casting, in order to prove out casting designs and/or manufacture the initial prototypes whilst the die tooling is being produced? This approach allows designers to have net-shape castings sooner, helping them to prove out designs and perform field tests in advance of the die tooling being completed. Design improvements can be realised and incorporated into the die tooling before it’s been completed, saving unnecessary delays. If you would like to learn more about how our rapid prototyping services support our low volume casting manufacture, please visit the rapid prototyping page on our website.

Alongside our low volume casting we offer a vast range of solutions such as surface finishing, heat treatments, part marking and of course a wide range of inspection services.
