Vacuum Casting Process in Rapid Prototyping

Prototype and mold preparation: Make or obtain a prototype or mold that needs to be casted. This can be a prototype made by 3D printing, CNC machining or other methods.
Mold assembly: Install the model into the mold, making sure the model is in the correct position and orientation.
Apply mold release: Apply a mold release agent to the contact surface between the prototype and the mold to ensure that the mold and casting can be easily separated after casting.
Vacuum chamber preparation: Prepare the vacuum chamber, making sure it is clean, and install the vacuum system, including vacuum pumps and gas handling equipment.
Material preparation: They are usually resins that are heated and processed to the desired chemical composition and temperature requirements.
Vacuum casting: The prepared resin material is loaded into the induction melting furnace and heated to the appropriate casting temperature under vacuum conditions. Vacuum conditions help reduce gas inclusions and impurities.
Injecting resin: Once the resin reaches the appropriate liquid state, liquid resin is poured into the cavity of the model.
Cooling and solidification: The resin is allowed to cool and solidify within the mold, forming the desired vacuum mold casting.
Model and casting separation: Once the casting has completely cooled, remove the casting from the mold. Because of the use of a mold release agent, the casting can be separated from the mold relatively easily.
Remove remaining material: Trim and remove any remaining vacuum mold casting material from the casting, such as flash or sprues.
Heat treatment (optional): Castings are heat treated as needed to improve material properties.
Testing and quality control: Inspection and quality control of castings, including dimensional measurements, X-ray or ultrasonic testing, to ensure they meet required specifications.
Secondary treatments: Carry out any necessary post-processing work such as surface preparation, cleaning and marking.
Packaging and delivery: Packaged castings can be delivered to the customer or used for further processing or assembly.
