Vacuum casting is an advanced technique that allows us to produce small-batch plastic parts through a cloning process. Our vacuum casting services are mostly used for prototype or end-use production and achieve immaculate results in every run. But, why is the method of vacuum casting prototyping used over other production approaches?
At Stephens Plastics, we strive to undergo a seamless process from start to finish for every project we are involved in. By adding vacuum casting to a manufacturing cycle, you are enabling batch production at rapid rates. Not to mention, you have a better chance of perfecting your products through this ingenious concept.

What is the process of vacuum casting?
This two-component technology formed of polyurethanes and silicone moulds creates a high-quality prototype or end result. Our vacuum casting services start with producing a master model using Stereolithography or Laser Sintering. We then set it in a silicone cast, applying vacuum pressure to avoid air bubbles.
Once the silicone is set, the mould is then cut into pre-defined parting planes after curing. Finally, the master is removed and a cavity then remains, ready for copying.

Why is vacuum casting used so often?
Due to the silicone used, components are of the highest quality; the finished outcome is even comparable to injection moulded products. Because of these excellent results, vacuum cast models are ideal for function and fitting testing, manufacturing final parts and for marketing purposes.
Not to mention, this is a very versatile technique as we are able to adhere to your exact finishing needs using our vacuum casting services. Using materials such as rubber, ABS, PC and PP, we offer a range of properties, as well as the ability to mix colour shades and even create transparent products. Precision is always met with our vacuum casting prototyping. Consequently, giving you peace of mind that prototypes mirror the final product accurately.
Additionally, we can then mass-produce the final product with ease, abiding by your batch size.

FAQs
What is vacuum casting in manufacturing? Vacuum casting is an advanced technique used to produce small-batch plastic parts by cloning a master model. This process is ideal for prototyping and end-use production, offering high-quality results similar to injection moulding.
How does the vacuum casting process work? The process involves creating a master model using technologies like Stereolithography or Laser Sintering. We set this model in a silicone mould under vacuum pressure to avoid air bubbles. Once the silicone cures, we cut the mould and remove the master, leaving a cavity for replication.
Why should I consider vacuum casting for my project? Vacuum casting is ideal for producing high-quality prototypes and final parts. It ensures precise replication of the master model, making it perfect for function and fitting testing, manufacturing final parts, and marketing purposes. The versatility in materials and finishes also allows for customised products.
How does vacuum casting ensure high-quality results? The use of silicone moulds and precise vacuum pressure ensures that components are free from air bubbles and defects. This results in prototypes and final products that are comparable to those produced by injection moulding.
What support does Stephens Plastics offer after the vacuum casting process is complete? Stephens Plastics provides ongoing support. This including the ability to mass-produce the final product according to your batch size. Our team ensures that all products meet the highest quality standards and are delivered on time.
