What You Need To Know About Silicone Vacuum Casting: The Entire Process Explained

by Nice Rapid | Mar 31,2020 | Silicone Vacuum Casting

The production of both small, as well as large plastic parts can be traced back to some old techniques of casting. However, with the latest technological expansion, the nature of vacuum casting can be considered, which results in using the method of copying, in manufacturing functional plastics. The main agent that is rather used in the process is silicone, hence the entire process is termed as "silicone vacuum casting". The quality of plastic products that you get with this technique is top-notch. Casting produces way more parts in a lesser amount of time than other techniques. Hence, let's take a look at the basics of the whole procedure!

What is the Main Idea Behind Opting for Vacuum Casting?

Silicone vacuum casting or simply, silicone molding, can be described as making of high-quality plastic parts, coated with the main agent. These are all tested to come to terms with the flexibility and routine use of the product. The main reason why this sort of vacuum casting should be opted for is because of the finer production costs and the marketing situation. Plus, the process of vacuuming ensures that the product reaches a finer degree of finishing, with shiny outer and a tough interior. Therefore, if require properly finished parts that will last longer, then vacuum casting is the only process to be opted for.

Where can Silicone Vacuum Casting Ideally be Used for?

Apart from the industrial manufacturing process in bulks, silicone vacuum casting is ideally fitted for other forms of applications as well. These are typically as follows:

  • When the product is said to be in the stage of pre-launching, this process can be used.
  • For any kind of quick household finishing tasks, vacuum casting is ideal.
  • Prototyping concept.

What are the Specifications of the Process?

Before industries head on to the manufacture of the products, some specifications need to be taken into account. These are as follows:

  • The wall thickness has a minimum as well as a maximum range. Therefore, to keep in mind the mold used fits perfectly; the maximum thickness should be assessed first. The wall should be 0.65 to 0.75mm thick here. In addition to that, the minimum range should be 1.5mm.
  • Now, there is also a mold size that can fit in the production chamber for the process of vacuuming. If the volume of the product is analyzed, then nothing more than 10 litres should go in.
  • The quantity of products that is listed per mold is said to be around 24 to 26. This again depends on the nature of the mold and its complexity.
  • When coming to terms with the surface structure of the mold, make sure it is perfectly smooth for the process of silicone vacuuming.

The Final Thought:

The possibility of silicone vacuum casting is huge. The products produced are top-notch and the minimum requirements are almost fulfilled. The variation in property allows better finishing, within a range of production!
