OEM Customized Small Batch Rapid Prototyping Silicone Vacuum Casting Plastic Parts

Product Description

Crida Silicone Vacuum Casting of Plastic Parts is a process used for small batch production and prototyping. It is first made by CNC machining or 3D printing (such as SLA, SLS) based on 3D drawings. For parts with complex structures, SLA printing is often used. Then the silicone mold is made. The silicone is poured around the master mold, the air is removed by vacuum, and then it is placed in a 40°C oven to cure. This usually takes 8-16 hours, depending on the size of the mold.

This is followed by vacuum casting. The resin is injected into the mold in the vacuum cavity under computer control. After injection, it is placed in the oven again to cure. Small parts require an average of 1-3 hours, and large parts require 3-6 hours. After curing, the part can be removed from the silicone mold and the cycle is repeated.

This process has significant advantages. It can accurately replicate part characteristics and details, with a smooth surface similar to injection molding. It is cheaper than mass production methods such as injection molding, suitable for small batch production. It has fast production speed and short turnaround time. The design allows complex designs and undercuts, which is suitable for product functional testing and prototyping. However, it also has limitations. For example, it is not suitable for mass production, and the silicone mold will degrade over time, affecting the quality and life of the casting.

Features

1. Significant cost advantage: Only one silicone mold needs to be made, which greatly reduces the cost compared with multiple metal molds required for injection molding. It is a cost-effective choice for projects with limited budgets and companies that pursue low-cost and fast design verification.

2. Superior surface quality: Silicone molds can accurately replicate the surface details of the master mold, and the vacuum environment can avoid the generation of bubbles. The surface of the finished product is smooth and flawless, without the need for complex post-processing. It is suitable for products with high appearance requirements, such as consumer electronic product shells, decorations, etc.

3. High dimensional accuracy: The production process is based on a 3D model, which can strictly control the dimensional deviation, and the accuracy can reach ± ​​0.3% (when the size is less than 100mm, the lower limit is ±0.3mm), which meets the production of parts with strict precision requirements, such as precision instrument parts, aerospace parts, etc.

4. Rich material selection: A variety of polyurethane resin materials can be used, each with unique properties, such as different hardness, transparency, and high temperature resistance. It can be flexibly selected according to product requirements to broaden the scope of application.

5. High design flexibility: allows complex design and undercut structure, can manufacture parts with complex shapes and fine internal structures, and provides broad space for product innovation design.

6. Short production cycle: From making master molds to producing parts, the entire process can be completed within a few days, and rapid delivery can meet the urgent development and iteration needs of products, and improve the company's market response speed.

Technical Parameters

Applications

Crida silicone vacuum casting plastic parts play an important role in the industrial and creative fields with their high efficiency and flexibility. In industrial manufacturing, the automotive industry uses this process to quickly manufacture samples of non-critical parts such as interior parts and air-conditioning vents, greatly shortening the R&D cycle; in the field of electronic products, from mobile phone shells to internal motherboard frames, the Crida process can accurately present design details to meet product iteration needs. In medical device manufacturing, medical equipment shells and components provide strong support for the development of the medical industry.

In addition, Crida silicone vacuum casting plastic parts also perform well in cultural creativity and aerospace fields. In the cultural and creative industry, personalized products such as figures and crafts can highly restore design details with this process to meet consumers' pursuit of uniqueness. In the aerospace field, complex-shaped parts such as aircraft ventilation ducts and small engine components can meet stringent performance standards with its high-precision and complex structure manufacturing capabilities, promoting the R&D and production of aerospace products.

Packaging and Shipping

Preparation before shipment

• Quality inspection: Conduct a comprehensive quality inspection on the produced parts to ensure that the dimensional accuracy, appearance quality, etc. meet the standards, and eliminate unqualified products.

• Packaging: Select appropriate inner packaging materials according to the characteristics of the parts, such as bubble film, pearl cotton, etc. to prevent collision and scratches. The outer packaging is generally made of cartons or wooden boxes. The wooden boxes need to be fumigated and marked with cargo information.

• Document preparation: Prepare customs declaration documents such as commercial invoices, packing lists, certificates of origin, etc. If there are special requirements for the parts, quality inspection reports or certification documents are also required.

Shipping and transportation

• Choose the mode of transportation: According to customer needs and the characteristics of the goods, you can choose air transportation (suitable for urgent or high-value lightweight parts) or sea transportation (suitable for large quantities of heavy parts).

• Booking and arranging transportation: Contact the freight forwarder or transportation company to book a space, determine the departure time and transportation route, and transport the goods to the designated location for shipment.

• Customs declaration and clearance: declare export to the customs, submit relevant documents, and cooperate with customs inspection. After the goods arrive at the destination port, assist customers with customs clearance procedures.

Logistics tracking and delivery

• Logistics tracking: Real-time status of goods transportation is monitored through the logistics tracking system, and transportation information is promptly fed back to customers.

• Delivery and receipt: After the goods arrive at the destination, they are delivered to the designated location according to customer requirements, and the customer signs for confirmation. If there are any problems, they will be coordinated and resolved in a timely manner.
