Vacuum casting china is a mid-to-low production volume process for customers who need high quality, cosmetic finish, end-use parts in a fast turnaround. We not only produce vacuum casting plastic parts with production-level quality but also offer a wide range of finishing services and post-machining services to ensure your requirements of quality, exterior looking, performance, and color selection are met.
Introduction of Vacuum Casting Service
Vacuum Mould Casting is a good manufacturing method to produce great quality prototypes and low volumes of parts from soft silicone mould. Its big advantage
when compared with injection moulding is that silicone ‘soft’ mold is made quicker and cheaper than metal ‘hard’ tool. The polyurethane parts from vacuum casting process in rapid prototyping are superior quality, precise and have the same great performance as the production parts.
Advantages of Vacuum Casting
Time SavingTime Saving
Typically, a silicone mold can cast about 15-25 parts. Also, soft tooling is cheaper and more time-saving than hard tooling.
Production QualityProduction Quality
The polyurethane vacuum cast parts have the same cosmetic and performance criteria with the production-level components.
SpeedSpeed
The molds can be made in 2 days, the polyurethane cast parts can be completed in 1-2 weeks, depending on the order volume.
Low CostLow Cost
A silicone mold is durable for 15-25 parts, making it affordable to produce mid-to-low production volumes when you would like to order 1 or 100+ pieces of parts.
Wide Material SelectionWide Material Selection
There is a wide array of rigid, flexible, rubber-like plastic materials available. The material can be tuned to your specific shore durometer from very soft (shore A) to very rigid (shore D).
A Wide Range of FinishesA Wide Range of Finishes
We offer a wide range of color options including clear, black, and Pantone/RAL color matching. We also provide a wide variety of custom surface finish options, which include sandblasting, plating and painting.

Vacuum Die Casting Process
The polyurethane vacuum die casing process has three major steps:
Building the Master Pattern.
The master pattern can be made using an subtractive manufacturing process, CNC machining or additive manufacturing process like stereolithography (SLA) or Selective Laser Sintering (SLS) 3D printing processes.
Creating the Mold.
Putting master pattern into a casting frame and filling the frame with silicone material to shape a mold. Once cured, the mold is cut into halves and the master pattern is removed, forming a cavity to cast parts. One master pattern can be repeatedly used to leave multiple molds, making the vacuum die casting process an optimal option for on-demand, mid-to-low production runs.
Casting Products.
Injecting the liquid polyurethane material into the silicone mould and then placing the silicone mold in a vacuum chamber. When the mold hardens, the mold halves are set apart and the polyurethanes can be casted in vacuum pressure. 15-25 copies can be casted throughout the casting process in a repeated way.
Vacuum Casting Tolerances
The finished dimensions of vacuum casting parts depend on the accuracy of the master piece, part structure and casting material. As a general role, ± 0.25% tolerance is expected.
Vacuum Casting Material
LC Rapid has hundreds of materials to meet your unique production needs. These casting polymers can meet industry-specific applications requirements. There is also a wide range of colors available range from opaque, translucent, completely transparent or colored to match specific color requirements.
