Frequently Asked Questions 

1. What are thermoplastic sheets for vacuum forming, and how are they used?

• Thermoplastic sheets for vacuum forming are plastic sheets that become soft and pliable when heated and can be shaped or molded into various forms using vacuum forming techniques. During the vacuum forming process, the heated thermoplastic sheet is placed over a mold, and vacuum pressure is applied to draw the sheet tightly around the mold, creating a precise and detailed replica of the mold's shape.
  
  

2. What are the key features of thermoplastic sheets used for vacuum forming?

• The key features of thermoplastic sheets used for vacuum forming include:
• Heat responsiveness: Thermoplastic sheets should soften and become pliable when heated to the appropriate temperature, allowing for easy molding and shaping during the vacuum forming process.
• Formability: Thermoplastic sheets should have good formability and stretchability to conform to complex shapes and intricate details of the mold without tearing or thinning excessively.
• Thickness options: Thermoplastic sheets are available in various thicknesses to accommodate different molding requirements and applications, ranging from thin gauge sheets for shallow molds to thicker sheets for deeper molds or structural applications.
• Transparency or opacity: Depending on the application, thermoplastic sheets may be transparent, translucent, or opaque, offering different aesthetic and functional properties for the finished products.
• Material compatibility: Thermoplastic sheets are available in a wide range of materials, including PETG, ABS, polystyrene, PVC, acrylic, and polyethylene, each with specific properties and suitability for different applications and end-uses.
