This is an introduction to the processing of parts trays and molded foam products!
Vacuum forming and pressure forming of resins and foams are possible. If you have any issues with molded products such as ABS, PVC, PP, or PS, please feel free to contact us.
It is possible to achieve a surface shape close to injection molding! It allows for the molding of thin plastic sheets.
"Pressure Forming" is a molding method that shapes a heated and softened plastic sheet by tightly pressing an air pressure box against a mold from above, using the pressure of compressed air to adhere the sheet to the mold, allowing it to take the desired shape. Since it applies several times higher pressure compared to vacuum forming, the finish boasts precision close to that of injection molding. The types of plastics that can be used include ABS, AES, PMMA, PC, PP, PE, HIPS, PET, PVC, and also super engineering plastics such as PEI, PSF, and PEEK. 【Features】 ■ Low cost for mold production ■ Shorter production time compared to injection molding ■ Suitable for small-batch production of various types ■ Material selection is possible if using thermoreversible plastics ■ Capable of handling large sizes *For more details, please refer to the PDF document or feel free to contact us.
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.
