Customized Silicone Vacuum Casting Parts For Five-camera plastic housing
Product Description
Crida silicone vacuum casting plastic parts are a process that uses silicone molds and vacuum environments to manufacture plastic parts. They are widely used in small batch production and product prototyping.
During production, 3D printing or CNC processing technology is first used to generate high-precision part prototypes, which is a key step to ensure the final quality of the parts. Then, the prototype is placed in a special frame and injected with liquid silicone that has been vacuum degassed. After the silicone solidifies, a silicone mold that can accurately replicate the details of the prototype is obtained, even the subtle structure or texture can be perfectly presented. Subsequently, a two-component polyurethane (PU) resin is mixed in a specific proportion and fully stirred. After vacuum degassed again, it is injected into the silicone mold under a vacuum environment. The vacuum environment ensures that the resin is evenly filled, avoids problems such as bubbles and shrinkage marks, and ensures the accuracy of the parts. After the resin is solidified, the mold is opened to remove the parts, and after post-processing processes such as trimming and polishing, a Crida silicone vacuum casting plastic part is completed.
The parts made by this process have high precision, smooth surface, low cost and short cycle, and play an important role in the automotive, medical, electronics and other industries.
Features
1. Low cost: Unlike traditional injection molding, which requires expensive metal molds, it only requires low-cost silicone molds, which greatly reduces the initial investment and is suitable for start-ups with limited funds, as well as cost-sensitive small-batch trial production and early product development.
2. Efficient production: The entire process from prototype to finished product usually takes only a few days, which is much faster than traditional processes. It can quickly respond to market demand, allow products to be quickly launched, and seize market opportunities.
3. Diversified materials: The main material polyurethane (PU) resin can imitate a variety of plastic properties through formula adjustment, such as high transparency and high strength like PC, and good fluidity like PP, to meet the diverse needs of different industries such as automobiles, medical care, and electronics for part material performance.
4. High precision: The tolerance can generally be controlled within ±0.05mm. With the help of advanced prototyping technology and high-precision silicone molds, the details of complex parts can be accurately restored to ensure accurate dimensions.
5. Excellent surface: Resin is poured in a vacuum environment to avoid bubbles. The surface of the parts is smooth and flat. In most cases, no additional grinding or polishing is required to achieve high appearance quality standards.
6. Flexible design: Silicone molds are flexible. When modifying the design, you only need to adjust the prototype and remold it. There is no need for complicated and expensive mold modification processes, which facilitates rapid product updates and iterations.

Applications
Low-Volume Production
Urethane cast parts are perfect for low-quantity production—when volumes do not justify investment in injection mold tooling—as well as for first run production parts, which can be completed weeks before production tooling is ready.
Advanced Prototyping
The urethane casting process and relatively inexpensive tooling involved make it easy and economical to make any necessary design changes. Additionally, different materials can be used with the same mold, making it possible to test designs with a variety of materials.
Market Testing
End-user functionality and a high-quality finish make urethane cast parts ideal for consumer testing, user evaluation and concept models. Using the cast urethane process means that changes can be incorporated quickly for either further testing or market launch.
