Vacuum and pressure forming
Vacuum forming, the easiest method to utilize in plastic molding. Additionally, pressure forming allows for the incorporation of design elements such as sharp lines.
This is an introduction to vacuum forming and pressure forming. For those who are not familiar with vacuum forming, most thin plastic trays are made using this method. Common examples include egg cartons. In pressure forming, where compressed air is used, thicker plastics can be utilized, allowing for the production of product covers and trays. **Advantages of Vacuum and Pressure Forming** - The molds are less expensive compared to other plastic forming methods (pressure forming tends to be more expensive than vacuum forming). - The production time for molds is shorter compared to other plastic forming methods. - It is suitable for small-scale production. - It can create thin-walled shapes (1-6 mm) and large products with wide surface areas. **Disadvantages of Vacuum and Pressure Forming** - There can be variations in thickness and precision, and partial thickness changes are not possible. - There is a significant amount of material waste. - Post-processing is essential. - It is not possible to create integrated shapes such as bosses or ribs. If you would like to convert covers made from sheet metal into resin or have questions about what shapes can be created, please feel free to contact us. We will provide proposals tailored to your needs.
