2. Sheet Extrusion: The plastic is melted and extruded into thin sheets of uniform thickness, ensuring consistency in the final product.
3. Pre-Heating: Before forming, the sheet is heated to its forming temperature, making it malleable enough to take the shape of the mold.
4. Molding and Trimming: The heated sheet is placed over a mold, and vacuum pressure is applied to shape it. Once cooled, the formed part is trimmed to its final dimensions.

Selecting the Right Plastic Sheet for Vacuum Forming
Choosing the right plastic sheet for vacuum forming is crucial for achieving the desired results. Factors to consider include:

• Material Properties: The sheet’s strength, heat resistance, and flexibility must align with the application’s requirements.
• Thickness: Thicker sheets are more durable but may require more heat and pressure during the forming process.
• Surface Finish: For aesthetic parts, sheets with smooth or textured finishes can enhance the appearance of the final product.

Vacuum Sheets for Packing and Transporting Automotive Parts
In addition to being used in forming components, vacuum sheets for packing are essential for safely transporting automotive parts. These sheets are molded into protective enclosures that shield delicate components from damage during shipping. Their lightweight and durable nature makes them ideal for reducing transportation costs and ensuring parts reach their destination intact.
