Urethane Casting - Silicone Molding
Vacuum casting (also known as urethane casting or silicone moulding) is a manufacturing method that uses silicone moulds to produce plastic parts in a relatively simple way and without the high costs and high lead times required for steel or aluminium moulds.
Urethane casting provides end use plastic parts, both rigid and flexible, with a quality close to the production level.
Our process of obtaining parts by vacuum casting, built without any expensive and time-consuming tools, always uses a master part made by CNC machining, thus ensuring the finish and quality of the final part.
Low Production Levels
Polyurethane, PU, parts obtained by vacuum casting are perfect for the production of small quantities – when volumes do not justify investment in injection moulds – as well as for the first series production parts, which can be obtained weeks before the production tools are ready.
Advanced Prototyping – Flexible Parts
Urethane casting process and the relatively inexpensive tools involved make it easy and economical to approximate the design and quality of the parts obtained to production levels. In addition, it is the ideal way to prototype elastomeric parts, with characteristics similar to those of Silicone, TPU, NBR,… and with hardnesses between Shore A 30 and Shore A 90.
A high quality finish makes polyurethane parts ideal for consumer testing, user evaluation and conceptual models. It also allows almost unlimited complexity, including internal corners without radii, unattainable with CNC machining, and designs without demoulding or with uniform wall thickness that cannot be injection moulded.
