Vacuum Casting Part

What is Vacuum Casting?

Vacuum casting, which is also referred to as polyurethane casting or urethane casting, serves as a flexible and budget-friendly manufacturing method utilised to create top-notch prototypes and produce small to medium batches of final parts. This technique is quite well-liked in various sectors like product development, automotive, aerospace, and healthcare.

How Does Vacuum Casting Work?

1. Master Pattern Creation

The process begins with the creation of a master pattern, typically made through methods like 3D printing or CNC machining.

2. Mould Fabrication

» Read More

A silicone mould is then created around the master pattern. This flexible mould captures all the intricate details of the master pattern.

3. Vacuum Casting Process

  • Material Preparation: Liquid polyurethane resin, chosen based on the desired material properties, is mixed.
  • Vacuum Chamber: The mould is placed in a vacuum chamber, and the mixed resin is poured into the mould.
  • Vacuum Application: The vacuum chamber is sealed, and air is evacuated, creating a vacuum. This helps remove any air bubbles from the resin, ensuring a detailed and precise cast.
  • Curing and Demolding: The resin-filled mould is then cured, causing the material to harden and take the shape of the mould. After curing, the mould is opened and the freshly formed component is demolded.

4. Finishing Touches

Post-processing steps may include trimming, sanding, and surface finishing to achieve the desired specifications.

Benefits of Vacuum Casting

Material Variety

Vacuum casting plays nice with loads of materials, like polyurethanes with different vibes, letting you match the project's mood.

Detail and Precision

It grabs all the tiny details from the master pattern, giving you super precise and smooth results, like it's a moulding pro.

Budget-Friendly for Small Batches

Perfect for those small to medium gigs, vacuum casting keeps costs low without the wallet-busting tooling fees of old-school moulding.

Rapid Prototyping

Vacuum casting enables the rapid prototyping of designs, allowing for quick iteration and testing of product concepts.Quick Turnaround: Compared to traditional manufacturing methods, vacuum casting typically has shorter lead times, accelerating the product development cycle.

Mould Reusability

Silicone moulds used in vacuum casting are long-lasting and can be reused for several manufacturing cycles, saving money.

Customization and Complexity

Vacuum casting accommodates the production of complex geometries and customised components, which makes it perfect for various industries and applications.
