Perfect for prototypes & short production runs
When precision and speed matter, Vacuum Casting/Urethane Casting is the bridge between prototyping and full-scale production. At Protosys Technologies, we deliver consistent, high-accuracy parts in small batches in various polymer like materials perfect for design validation, functional testing, or limited production runs.
Vacuum Casting is used extensively to make functional prototypes for marketing and consumer trials or production parts for lower volume. These trials for new products require functional prototypes without incurring a large cost and time delay. Even though these are low volume production, they consist of a broad range of materials that closely align with final production materials such as plastics, threads and inserts, multiple cavity tools, and overmoulding.
In traditional subtractive or formative technologies, an object is manufactured either by carving or shaping material into the desired objects. In Additive Manufacturing, an object is manufactured or printed directly onto a print bed via the use of CAD software. With the aid of a computer generated 3D model, the object is split it into several cross sections and then built on the print bed by adding the material layer upon layer until the process is completed.
Vacuum casting creates high-quality prototypes by pouring liquid materials into silicone molds, offering precision, consistency, and cost efficiency for low-volume production.
Low cost and quick turnaround times as compared to injection moulding/ 3D printing.
Parts can be manufactured in low volume from one to hundreds
No post processing or finishing required.
Parts can be made in flexible or rigid plastics
Acrylonitrile butadiene styrene is popular due to its low production cost. Protosys Technologies offers ABS like material in PX223 (Axon) and SG95 (Renishaw)
Polypropylene is one of the most widely used plastics and is very easy to mould. Protosys Technologies offers PP like material in 8045 (Renishaw)
Glass filled polymers increase structural strength, impact strength, and rigidity. Protosys Technologies offers Glass filled (30%) material in VC3368 (Alchemi)
Polycarbonate offers high impact resistance and is available in transparent variations. Protosys Technologies offers PC like material in Transparent 5210, 1810
Wax can be formed into nearly any form imaginable and offers the ability to create surface textures. Wax is available in the form of wire, sheets, and sprues.
Metal powders are used mainly in DMLS and produce parts for high-end engineering applications. The metal parts produced have high strength, high hardness, and high thermal capacity. Protosys Technologies offers Stainless Steel, Aluminium, and Titanium.
