High Precision Vacuum Casting Silicone Mold Small Batch Plastic Parts

Silicone Vacuum Casting Resins Mold Vacuum Casting Master Or Mass Production

Product Description

Crida's silicone vacuum cast plastic parts are manufactured through an efficient and precise process, which has significant advantages in the field of small-batch production and prototyping.

The process of silicone vacuum casting is not complicated. First, a master model is made through 3D printing or CNC machining based on the designed 3D model. Then, the master model is placed in a specific frame, silicone is poured in, and after the silicone is cured, it is cut into two parts to obtain a silicone mold. Then, liquid polyurethane resin is mixed in a precise proportion, poured into the silicone mold, and placed in a vacuum environment. Under the action of vacuum, the bubbles in the resin are effectively discharged, ensuring the quality of the part. After a period of curing, the molded part is removed from the mold, and then the quality is checked. The part is polished, painted and other post-processing work is performed, and a perfect silicone vacuum cast plastic part is born.

The parts made by this process have many advantages. In terms of precision, thanks to the 3D model and vacuum environment, the design details can be accurately reproduced, and the dimensional error can be controlled within a very small range. For example, when making complex mechanical parts prototypes, the internal fine structure can be perfectly presented. Its surface finish is extremely high, comparable to injection-molded parts, and does not require too much post-polishing treatment. For example, the shell of electronic products has a smooth and delicate surface. Moreover, the process is highly flexible and can use a variety of materials, such as imitation ABS, PP, PC, etc., and can also adjust the material properties according to needs to meet the use environment of different products. In terms of cost, compared with processes such as injection molding that require expensive metal molds, silicone vacuum casting only requires the production of a silicone mold, which greatly reduces the initial investment cost and is extremely cost-effective for small-batch production.

Of course, silicone vacuum casting plastic parts also have certain limitations, such as limited mold life, each mold can produce about 20-25 castings, which is not suitable for large-scale production. When producing parts with thicker materials, uneven heating and molding problems may occur. However, in general, Crida's silicone vacuum casting plastic parts have been widely used in many fields such as automotive parts manufacturing, medical device research and development, and consumer electronics production due to their unique advantages, providing strong support for product innovation and rapid iteration.

Advantages

Crida's silicone vacuum casting plastic parts have many significant advantages and are outstanding in the field of small-batch production and prototyping. From the perspective of cost and efficiency, the cost of silicone molds is much lower than that of traditional injection molding metal molds, which greatly reduces the initial investment and allows companies, especially small and medium-sized enterprises with limited budgets, to start the product development process at a lower cost. At the same time, the silicone mold production cycle is short, usually completed within one day, and a single mold can produce about 20-25 parts, with high overall production efficiency, which can effectively shorten the product development and listing cycle and quickly respond to market demand.

In terms of product quality and process flexibility, the part also performs well. The part has extremely high precision and can accurately restore the subtleties of the 3D model with extremely small dimensional errors, which can fully meet the needs of products with strict precision requirements. The surface quality is excellent, smooth and flat, and basically no post-polishing treatment is required. The material selection is also very diverse, supporting imitation ABS, PP, PC and other materials, and can also adjust the material properties according to the actual use scenario of the product, such as enhancing weather resistance and improving flexibility, etc., to meet the complex needs of different industries and different products. It is widely used in many industries such as automobiles, medicine, and electronics.
