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.
