Advantages of Vacuum Casting

As a leading vacuum casting manufacturer in China, NOBLE provides low-cost manufacturing of high-quality plastic parts. Our vacuum casting services provide short-cycle solutions for creating high-quality prototypes and low-volume part production.

Vacuum casting, or urethane casting, is a technique that combines a silicone mold with a 3D printing master to create vacuum-cast parts with consistent performance and production-grade quality. The technology requires no costly up-front investment, allows for flexible, economical production, and process hardens thermoplastic polyurethane in silicone or epoxy molds. The result is a vacuum-cast part with the same shape as the original master model. The final dimensions of a vacuum cast part will depend on the master model, part geometry, and material chosen.

Our Vacuum Casting from Prototyping to Production

Vacuum casting is a versatile process that seamlessly transitions from prototyping to low-volume production, offering numerous benefits throughout each stage.

At room temperature, PS is normally a solid thermoplastic but can be melted at higher temperatures for molding or extrusion, and then resolidified.High-impact strength, low-cost resin with a wide range of options.



Elastomers are polymers with viscosity and elasticity and therefore are known as viscoelasticity. The molecules of elastomers held together by weak intermolecular forces generally exhibit low Young’s modulus and high yield strength or high failure strain. Examples are Natural rubber, Silicone Polyurethanes, and Polybutadiene, Polyurethane plastic resin.

Surface Finishes for Vacuum Casting

NOBLE can build unique surface layers for your vacuum casting parts using a wide range of surface finishes. These finishes assist you in meeting the aesthetic, toughness, and chemical resistance needs of your products. We can provide the following surface finishes based on your material selection and part application:

图片1GlossyA grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces on injection molded parts.
图片2Semi-glossyB grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Custom molded plastic parts that undergo B grade finishing have a matte surface texture.
图片3MatteC grade finishes use grit sanding stones to produce a rough, uneven surface. Injection plastic parts that undergo C grade finishing have a matte surface texture.
图片4TexturedD grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.

Our Vacuum Casting Services Process

Vacuum casting is a cost-effective way to create high-quality prototypes and low-volume production parts with great detail and material options. Here are the steps involved:

  • Step 1. Master Pattern Creation

    The process begins with the creation of a master pattern, which serves as the original model for replication. The master pattern can be produced using various methods, such as 3D printing, CNC machining, or traditional fabrication techniques.

  • Step 2. Mold Preparation

    A silicone mold is created around the master pattern. The mold is typically made in two halves, allowing for easy removal of the pattern and subsequent casting. The mold is then secured within a casting frame.

  • Step 3. Mold Release and Preparation

    Prior to casting, a mold release agent is applied to ensure the easy removal of the final casted part from the mold. The mold is then preheated to a specific temperature to enhance material flow and reduce curing time.

  • Step 4. Material Mixing and Vacuum Degassing

    The chosen casting material, usually a two-part polyurethane (PU) resin, is mixed thoroughly to achieve a homogeneous consistency. The mixed material is then placed in a vacuum chamber to remove any air bubbles or voids that could affect the final part's quality.

  • Step 5. Casting Process

    The prepared mold is placed in a vacuum casting machine. The machine creates a vacuum within the chamber, which helps to draw the liquid resin into the mold, ensuring precise replication and minimal defects. The resin is poured into the mold under vacuum conditions, filling the cavities and replicating the desired geometry.

  • Step 6. Curing and Solidification

    After the mold is filled, the casting is left undisturbed to cure and solidify. The curing time varies based on the resin type, thickness of the part, and ambient conditions. If necessary, heat or post-curing may be applied to accelerate the curing process

  • Step 7. Mold Opening and Part Extraction

    Once the resin has solidified, the mold is opened, and the cast part is carefully removed. The mold can then be reused multiple times to produce additional parts.

  • Step 8. Finishing and surface treatment

    To achieve the desired aesthetics and functionality, the casted part may require finishing and surface treatment, such as trimming excess material, sanding, painting, or surface treatments.

Vacuum Casting FAQs

  • Q

    What is vacuum casting?


    Vacuum casting is a manufacturing process that involves creating replicas of a master pattern by pouring liquid resin into a silicone mold under vacuum conditions. It is commonly used for prototyping and low-volume production of complex parts.

  • Q

    What materials can be used in vacuum casting?


    Vacuum casting is compatible with a wide range of materials, including polyurethane (PU) resins. These resins come in various formulations, offering different mechanical properties, colors, and finishes to suit specific application requirements.

  • Q

    How does a vacuum casting work?


    Vacuum casting is a manufacturing process used to create prototypes or small production runs of plastic parts. It involves creating a mold around a master pattern, pouring liquid resin into the mold, and using a vacuum to remove air and ensure complete resin filling. The resin is then cured, and the mold is separated to remove the solidified parts. Vacuum casting allows for high-quality replicas with detailed features and is cost-effective for low-volume production.

  • Q

    Why use vacuum casting?


    vacuum casting provides a flexible, cost-effective, and efficient solution for creating prototypes, producing low volumes of parts, and achieving high-quality replicas with intricate details and fine finishes.

  • Q

    How long does vacuum casting lead take?


    The lead time for vacuum casting can vary depending on several factors, including the complexity of the part, the number of parts required, the specific requirements of the project, and the capacity of the manufacturing facility. Generally, the lead time for vacuum casting can range from a few days to a few weeks.

  • Q

    Is vacuum casting cheaper than injection molding?


    It's important to note that the cost-effectiveness of vacuum casting versus injection molding can vary depending on the specific project requirements. For high-volume production runs, injection molding becomes more cost-effective due to the amortization of tooling costs over a larger number of parts. It's recommended to assess the specific needs of your project and consult with manufacturers or service providers to determine the most cost-effective manufacturing method.

  • Q

    What are the advantages of vacuum casting for prototyping?


    Vacuum casting offers several advantages for prototyping, including quick turnaround times, cost-effectiveness, and the ability to produce functional prototypes that closely resemble the final product in terms of aesthetics and physical properties.

  • Q

    What is the minimum thickness for vacuum casting?


    The minimum thickness for vacuum casting can vary depending on several factors, including the material being used, the complexity of the part geometry, and the specific capabilities of the vacuum casting process being employed. However, as a general guideline, a minimum thickness of around 0.5-1 mm is often considered feasible for vacuum casting.
