Custom Silicone Vacuum Casting Prototypes For Five Camera Plastic Housing

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.

Technical Parameters

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.

Packaging and Shipping

Packaging

• Protective packaging: First, use soft and cushioning materials such as bubble film and pearl cotton to carefully wrap the parts to prevent collision and friction during transportation. For some high-precision, fragile or special surface requirements, customized EVA lining or foam molds will be used to fix them to ensure that they will not shake in the package.

• Moisture-proof treatment: If the parts are sensitive to humidity, they will be packed in sealed plastic bags and desiccant will be placed in the bags to prevent moisture from affecting performance or appearance during long-term international transportation.

• Labeling and packing: Classify by order and part model, and mark each part or package with clear product information, such as part number, specifications, etc. When packing, place a detailed shipping list in the box, indicating the number, model and other information of the parts. The outer box needs to be posted with English warning labels such as "fragile" and "handle with care", as well as logistics labels such as destination and order number.

Shipping

• Logistics method selection: Choose the appropriate logistics method based on the number, weight, volume of parts and customer requirements for delivery time. Small batches of light parts with high timeliness requirements are usually shipped by international express such as DHL and FedEx; large quantities of parts may be shipped by sea or air freight forwarding to reduce transportation costs.

• Preparation of customs declaration and customs clearance documents: Prepare accurate and complete customs declaration documents, including commercial invoices, packing lists, certificates of origin, etc., to ensure that the goods can pass the customs inspection of the exporting and importing countries smoothly. The invoice must specify the name, quantity, value and other information of the parts in detail to avoid problems during customs clearance.

• Logistics tracking and after-sales: After delivery, the logistics order number will be provided to the customer in a timely manner, and the transportation status of the goods will be monitored in real time through the logistics tracking system, and logistics information will be fed back to the customer in a timely manner. If the parts are damaged or lost during transportation, communicate with the customer in a timely manner and assist the customer in claims and subsequent processing.
