Vacuum Casting Service
Vacuum Casting (Urethane Casting) is a copying technique used for the production of small series of functional plastic parts or flexible rubber parts.
Using two-component polyurethanes and silicone molds, Vacuum Casting is known for its fast production of high-quality prototypes or end-use products, which is accurately mimic the color, texture, feel and other physical properties achieved. Depend on many years of expertise in the field, Eco Industrial have capable of handling your vacuum casting and silicone molding needs.

Why Choose Vacuum Casting?
Silicone molding results in high-quality parts comparable to injection-molded components. This makes vacuum casted models especially suitable for fit and function testing, marketing purposes or a series of final parts in limited quantities. Vacuum casting also lends itself well to a variety of finishing degrees, and we can match the finish you need for your parts. It can help to minimize the molding time to produce your products at low quantities. Compared to conventional methods, molding costs are much lower.
- Wide range of choice multiple resins, suitable for various size, finishing options
- Accurate and high quality cast copies with an immaculate finish, so you have a wider choice of flexibility, hardness and rigidity that you want in your products
- Speed to market delivered within 7 to 10 days to make around 50 functioning prototype parts, in most instances, quick turnaround for a reduced time to market.
Technical Details Of Vacuum Mold Casting
Maximum Castable Workpiece: 2000 mmX1000mmX800mm
- Pouring Parts Thickness: minimum 0.5 mm, optimum 1.5 mm-5mm
- Shrink Mitigation: A shrinkage rate of +0.15% can be expected due to thermal expansion of the liquid, and the response of the flexible mold
- Standard Lead Time: Up to 10 copies within 10 working days
- Tool Life: Up to 25 copies per mold (depending on the mold’s complexity and the casting materials)
- Surface Structure: It is externally smoothed to a satin or matte surface. Grow lines may be present on internal or difficult-to-access features. Polishing or custom finishes must be clearly defined and agreed upon at the point of order
How Does Vacuum Casting Work?
- Have high-quality master model
can be the industrial part itself, it also can be made by CNC machining or with 3D Printing. You should always ensure that the master model being used is of the correct dimensions and looks. This is to ensure that no flaws are transferred to the model prototype after finishing the process.
- Cure process
The master model is then encapsulated into a two-part silicone rubber mold. The mold is cured under high temperatures to ensure that the two parts stick together. this is used to strengthen the mold and make it more durable. After curing, the master is cut out to leave a cavity into which a variety of polyurethanes can be cast under vacuum.
- Filling The Resin
You should fill the mold with the designated material. The resin replicates the characteristics of industrial material. The resin material is usually mixed with any coloring pigment to achieve aesthetic or specific functional properties. After the mold is filled with the resin material, it is place in the vacuum chamber. It is placed in the vacuum chamber to ensure that there are no air bubbles in the mold, this is to ensure that the final product is not ruined or damaged.
- Final Cured Process
The resin is placed in the oven for the final cured stage. The mold is cured in high temperatures to ensure that the material is strong and durable. The silicone mold is removed from the mold so that it can be used in making more prototypes. After the prototype is removed from the mold, it is painted and decorated. The painting and designs are used to ensure that the product has a gorgeous final look.
