Product Description
Crida silicone vacuum casting plastic parts is an advanced process suitable for small batch production and prototyping. The process starts with the production of the master mold. According to the 3D design drawings, the master mold is completed by CNC machining or 3D printing (such as SLA, SLS technology). Especially for complex structural parts, 3D printing can accurately present details. Then the silicone mold is made, the silicone is evenly poured around the master mold, the air is removed by vacuum equipment, and then placed in a 40°C oven for 8-16 hours (the time varies depending on the size of the mold). Finally, the vacuum casting process is carried out. The resin is injected into the vacuum cavity mold under computer control. After injection, the secondary curing is completed. Small parts take 1-3 hours and large parts take 3-6 hours to cure. The parts can be demoulded and taken out for recycling.
The vacuum casting process can accurately reproduce the characteristics and details of parts and produce finished products with smooth surfaces and similar injection molding effects. Compared with large-scale production methods such as injection molding, it is less expensive and more suitable for small-batch manufacturing needs. It has a short production cycle, fast response speed, and high design flexibility, and can achieve complex shapes and bottom-cut structures. It is often used in product function testing and prototype design. However, its silicone mold has a limited service life and is not suitable for ultra-large-scale mass production. In actual applications, it is necessary to weigh the pros and cons.
Advantages
In terms of cost, it is inexpensive. Only one silicone mold needs to be made, unlike injection molding, which requires multiple metal molds, which greatly reduces the mold cost. At the same time, the commonly used materials for casting, such as silicone and polyurethane resin, are affordable, and the whole process has low energy consumption, which further reduces expenses and is very friendly to projects with limited budgets.
In terms of technology, high-precision replication can be achieved. The mold is made based on the 3D model to ensure that the finished product is highly consistent with the design. The production under a vacuum environment avoids the generation of bubbles. The parts are accurate in size and smooth in surface. No complex post-processing is required. Products with high precision requirements, such as precision instrument parts, can also be easily handled.
The production efficiency is also very high. The cycle from design to finished product is short, and the mold is made quickly and can be reused many times. Small batch production can be completed within a few days, quickly responding to market demand and helping to quickly iterate products. Moreover, it is flexible in design and can produce parts of any size and shape to meet the needs of complex designs and undercut structures, fully releasing design creativity.

Technical Support & Services
Crida provides comprehensive technical support and services for vacuum-cast plastic parts. In terms of technical support, it has a professional team of engineers who can provide assistance from the early stage of product design. If the customer's design has a structure that is not conducive to casting, the team will give optimization suggestions based on rich experience and the characteristics of vacuum casting process, such as adjusting the wall thickness and improving the demoulding angle to ensure that the parts are easy to produce and improve the yield rate. In terms of material selection, engineers will select the most suitable from a variety of applicable materials according to the use scenarios and performance requirements of the parts, such as whether they need to be resistant to high temperatures and have high toughness, and introduce the material characteristics and advantages in detail.
At the service level, Crida focuses on communication efficiency and delivery quality. From the customer's consultation, a dedicated person will be arranged to connect, respond to questions quickly, and give a preliminary evaluation and quotation of the project within 24 hours. After the order is confirmed, the production progress is strictly controlled, and real-time tracking is carried out through the system, and feedback is given to customers regularly to ensure on-time delivery. After the product is delivered, if the customer has any problems with the quality of the parts, Crida provides an after-sales guarantee, timely communication, analysis of the reasons, unconditional return or repair, until the customer is satisfied, and wins the trust of customers with professional and responsible services.
