You cannot change the shape of cured Viton by heating it.Stormer said:But do it behave like a thermoplastic where you can for example buy a sheet of finished Viton rubber, heat it up and then vacuum form it to the shape you want?
I want to make some rolling diaphragm seals for a pressurized Stirling motor so i don't have to pressurize the crankcase. So the material needs to be both heat resistant and relatively strong (it will be backed up with pressurized oil). Maybe silicone will work if i get a hard enough type? But i don't think the really soft type of silicone i have usually seen will work for this.Baluncore said:I would want to check first why you need to use a "Viton® like" polymer, and why a two part silicone compound would not be a much easier material to obtain, cast and cure. What are you trying to make, and why must it use Viton®.
Thermoforming is a manufacturing process in which a plastic sheet is heated and then formed into a specific shape using a mold. The heated sheet is then cooled and trimmed to create a final product. This process is commonly used to create packaging, automotive parts, and other plastic products.
Yes, Viton sheets can be thermoformed at home using a vacuum forming machine. However, it is important to have proper training and knowledge of the process to ensure safety and quality results. It is recommended to seek professional assistance for more complex projects.
Viton is a high-performance synthetic rubber that is known for its excellent chemical resistance, high temperature resistance, and durability. Thermoforming with Viton sheets allows for the creation of products that can withstand harsh environments and have a longer lifespan.
The basic tools and materials needed for DIY thermoforming with Viton sheets include a vacuum forming machine, heat source (such as a heat gun or oven), mold, and Viton sheets. Additional materials such as clamps, release agents, and trimming tools may also be necessary depending on the project.
Yes, it is important to follow safety precautions when working with heat and plastics. This includes wearing protective gear such as gloves and eye protection, working in a well-ventilated area, and following proper handling and disposal guidelines for the materials used. It is also important to have a thorough understanding of the thermoforming process to prevent accidents and injuries.
