Heat Moldable Plastic Sheets

Vacuum forming plastic sheets are thermoplastic materials specifically designed for the vacuum forming process. Vacuum forming is a manufacturing technique used to shape plastic sheets into various three-dimensional forms or products. The process involves heating the plastic sheet until it becomes soft and pliable, then placing it over a mold or a forming tool. A vacuum is then applied to remove the air between the sheet and the mold, causing the plastic to conform to the shape of the mold. Finally, the plastic is cooled to retain the formed shape.

Vacuum forming plastic sheets are typically made from various thermoplastic materials, such as ABS (Acrylonitrile Butadiene Styrene), PVC (Polyvinyl Chloride), PETG (Polyethylene Terephthalate Glycol), and polystyrene (PS). Each type of plastic offers different properties, such as impact resistance, flexibility, transparency, and chemical resistance, making them suitable for different applications.

These plastic sheets are available in different thicknesses and sizes to accommodate various product designs and requirements. Vacuum forming is widely used in industries like packaging, automotive, aerospace, medical, and consumer goods, where it allows for cost-effective production of custom-shaped plastic products with low to medium production volumes. The versatility and ease of use in vacuum forming make it a popular choice for creating a wide range of plastic products and components.

Thermoforming vs vacuum forming

Thermoforming and vacuum forming are both plastic forming processes used to shape thermoplastic sheets into three-dimensional products, but they differ in their specific techniques and applications:``


- Thermoforming is a broad term that encompasses various plastic forming processes, including vacuum forming.

- In thermoforming, the plastic sheet is heated until it becomes soft and pliable.

- Once heated, the plastic sheet is formed into the desired shape using a mold or forming tool.

- The forming can be achieved through various methods, such as vacuum forming, pressure forming, or mechanical forming, depending on the specific requirements.

- Thermoforming can produce products with different levels of complexity, from simple shapes to more intricate designs.

- It is used for a wide range of applications, including packaging, automotive parts, trays, and consumer goods.

Vacuum Forming:

- Vacuum forming is a specific type of thermoforming process.

- In vacuum forming, the heated plastic sheet is placed over a mold, and a vacuum is applied to remove the air between the sheet and the mold.

- The vacuum force pulls the plastic sheet tightly against the mold's surface, conforming the sheet to the mold's shape.

- After the plastic cools and solidifies, it retains the formed shape, and the final product is removed from the mold.

- Vacuum forming is often used for producing shallow or moderately deep parts with relatively simple geometries.

- It is commonly used for applications such as packaging trays, displays, and low-cost prototypes.

In summary, the main difference between thermoforming and vacuum forming is that vacuum forming is a specific subset of thermoforming, where the forming process relies on the use of a vacuum to shape the heated plastic sheet against a mold. Thermoforming, on the other hand, encompasses a broader range of plastic forming processes, which may include vacuum forming as one of its techniques.
