The process of Vacuum Casting has become extremely popular in recent years, with both big business and small making use of this quick and cost-effective method of prototype building. Having built a master model which is highly finished, vacuum casting creates multiple replicas at the same high standard of the one-off piece, but in a material with better mechanical properties.

1: Functional Benefits

In terms of functionality, there are a host of benefits of vacuum casting. The PU resins that are used in vacuum casting will imbue the part, be it for fire retardation or electrical and shock resistance. Vacuum casting is also the best way of creating unusual shapes with differing thickness. While other methods can be used to form difficult shapes, vacuum casting is the quickest and most reliable way of getting the job done.


2: Aesthetic Benefits

From an aesthetic point of view, vacuum casting produces a high-level of production accuracy as well as offering a number of different finishing options. Vacuum casting allows the addition of colour during the manufacturing process, adding the colouring pigments along with the resin components to ensure the final piece comes out with the exact colour required. Mixing colours with the resin means a variety of different finishes can be used for the part, whether it’s gold or even marble rather than the more typical colours.


3: Different Uses

One of the real success stories of vacuum casting is just how many different sectors it has been used in. As well as being used to produce a host of plastic prototypes for consumer goods and product marketing, vacuum casting has been used in industries as wide apart as medical and aerospace.

The automotive industry is another to have utilised vacuum casting for their prototypes. One recent example of our vacuum casting work in this sector was to create this Lamborghini tail light.

But it’s not just big businesses that can benefit from vacuum casting, with the process increasingly being used by interior designers to create decretive objects in low volume such as wall plaques and smaller ornaments.


4: Cost and Speed

The main benefit of vacuum casting to businesses might be its accuracy and the exceptional finish of the piece, but the speed it takes to turnaround a product is also another selling point. As well as appealing to those companies needing to design and produce a prototype quickly, vacuum casting means designers aren’t afraid to take chances with products.

The difference in time is one thing that makes vacuum casting a popular process, the other is the cost. For one-off prototypes or short run batches, vacuum casting comes in at a fraction of the price of other methods such as plastic injection moulding, resulting in an exceptionally finished end product.
