1: Master Model Creation
At the very begining, we need to make a product as a master model of the product before making silicone molds and parts , typically using Stereolithography (SLA), other 3D printing technologies or CNC machining. The master model must accurately reflect the final product’s size, shape, structure and all details.
3: Mold Curing and Cutting
After curing, high-precision cutting techniques are used to cut the mold along precise cutting lines, ensuring the integrity and reusability of the mold. it needs to be very carefully when cut the mold to stop any damage during operation.
5: Precise Curing Control of Parts)
During the curing process, temperature and time are precisely controlled to ensure the material is fully cured and retains the desired physical and chemical properties. Curing parameters may vary for different types of resins.
7: Surface finishing
Whether the product need surface treatment or not, it depends on customer requirements, we can offer surface finishing like sanding, painting, sandblasting, or other surface treatments are performed. These steps are crucial for enhancing the aesthetic and functional aspects of the parts.
2: Silicone Mold Making and Reinforcement
In making the silicone mold, it’s important to ensure no air bubbles and reinforce the mold to prevent deformation. This is often achieved by adding a support frame or applying external pressure during the silicone curing process.
4: Controlled Casting Environment
Casting is performed in a strictly controlled vacuum environment to ensure uniform distribution of the material and reduce defects. Specific temperature and pressure parameters are used to ensure optimal flow and curing of the material.
6: Complex Demolding and Cleaning Process
Removing the part from the silicone mold is a technically demanding step that requires care to avoid damaging the part or the mold. The cleaning process involves removing support structures and trimming any flashes.
8: Rigorous Quality Control and Inspection
Each part undergoes rigorous quality control and inspection to ensure they meet the design specifications and customer’s quality requirements. This includes dimensional checks, visual inspection, and functional testing.

Regardless of your professional background, this article aims to offer you in-depth insights into Vacuum Casting, aiding you in making wise decisions in the realm of manufacturing.
Low Cost
Compared to other precision manufacturing methods like injection molding, Vacuum Casting offers relatively lower manufacturing costs, contributing to overall project cost reduction.
Fast Lead Time
The process offers a high level of customization, allowing the production of parts in different materials, colors, and textures according to customer specifications. This is crucial for meeting diverse market demands.
Complex Geometries
is suitable for manufacturing parts with complex geometries, which can be challenging with traditional manufacturing methods. This flexibility is essential for designing unique products or models, such as artworks, creative products, and specialized parts.
Rapid Prototyping Validation
In the early stages of product design and development, vacuum casting is ideal for creating high-fidelity prototypes that closely resemble the final product in material and texture. It allows designers and engineers to conduct thorough design validation, including dimensional accuracy, assembly testing, and functional assessment. This is crucial for iterative design, error discovery, and improvements.
Low-Risk Small-Batch Production
For custom products or new products in market testing phases, vacuum casting is an effective way to low risk and time-efficient small batch production. It allows for the rapid production of a small quantity of high-quality parts without the investment in large-scale production facilities. This is particularly useful in cases of uncertain market demand or high product customization.
High Customization & Repeatable
The process offers a high level of customization, allowing the production of parts in different materials, colors, and textures according to customer specifications. This is crucial for meeting diverse market demands.
Not Suitable for High-Volume Production
Vacuum Casting is best suited for small-batch production and custom manufacturing. each mold can only produce 10-20 good parts, the quality and tolerance will be affected with more parts produced, For projects requiring large-scale production, other manufacturing methods like injection molding will be more appropriate.
Size and Weight Limitations
Vacuum Casting primarily relies on gravity to allow resin to enter the mold, it is constrained by the size and capacity of the molds, making it generally unsuitable for producing large parts. Large components may require larger molds, which can increase manufacturing costs and potentially introduce process challenges. Heavier components may require more time to completely fill the mold, potentially leading to uneven or unstable manufacturing.
