Even application of high viscosity silicone oil: Spray application to seat cushions

For automobile seat cushioning materials (urethane foam), a process of applying “silicone oil” immediately after molding is used to improve comfort and durability. However, the actual application process presented the following challenges:

• The uneven shape of the urethane foam causes uneven application
  The urethane foam used in seat cushions has an uneven surface, which makes it difficult to achieve a uniform coating when sprayed, as this can easily result in uneven film thickness.
• Unstable atomization and scattering occurs with high viscosity silicone oil
  The silicone oil used has a high viscosity, which means that atomization is unstable with conventional spray nozzles, resulting in uneven application and frequent scattering.
• Difficult to stabilize quality and low reproducibility
  Manual application tends to depend on the experience of the operator, resulting in variations in film thickness and finish, making it impossible to ensure repeatable quality.

• Improved spray application stability and reduced scattering and dripping
  The SV01S’s precise spray control ensures stable atomization even with high-viscosity silicone oils up to 30,000 mPa・s. Splashing and dripping are significantly reduced, enabling a clean process.
• Ensures uniform film thickness even when coating on complex shapes
  The non-contact spray conforms to the shape of uneven urethane foam materials, forming a uniform film thickness.
• Standardizing quality and automating production lines is now possible
  Previously, this was a frequent occurrence.Almost no need for reapplication or repairsThis reduces the burden on workers. The coating process is becoming more automated and standardized.Improving productivity across the entire linecontributed to.
