Overview of Thermoforming and Vacuum Forming
Thermoforming and vacuum forming are both frequently used manufacturing methods for producing components. The thermoforming process entails heating thermoplastic sheets to a workable temperature. After heating, the thermoplastic is formed into the desired shape using a mold, and then excess material is trimmed to create the completed product.
Vacuum forming takes thermoforming one step further. In vacuum forming, the process applies vacuum pressure to more effectively mold the part. The vacuum pressure sucks the plastic down onto the mold to allow for consistent thickness and improved detail.
Uses and Advantages of Thermoforming
There are several key uses and advantages of thermoforming that make it one of the most popular processes across a wide range of applications.
Thermoforming is applicable to many uses. One of the most common applications is rigid packaging for consumer goods and food products. However, thermoforming is also used in many other types of applications because of its dependability and efficiency. Some other potential uses for thermoforming include everything from creating long-lasting surfaces on automobiles to manufacturing children’s toys.
The thermoforming process comes with numerous advantages, including:
- Adaptable. One of thermoforming’s main benefits is that it is very adaptable to a wide range of design requirements.
- Quick turnaround. Thermoforming provides quick turnaround times, making it ideal for prototype development and last-minute shipments.
- Cost-effective. Thermoforming is cost-effective, as materials are optimized to keep costs lower, including costs associated with tooling.
- Aesthetically pleasing. Final products can be visually appealing. Certain paintable and colored plastics can undergo the thermoforming process, which allows for even further customization.
Why Vacuum Forming is a Popular Method
A large number of applications use vacuum forming in particular due to its streamlined process. Vacuum forming begins with the placement of a plastic sheet within vacuum forming machinery, which then heats and subsequently softens the plastic to make it more pliable. The system then places the heated sheet over a pre-made mold, which is often made with aluminum for durability and reusability. Once the plastic sheet comes into contact with the mold, the vacuum is activated, which applies suction to effectively remove the air within the chamber and cause the plastic to tighten on the mold to conform to its shape.
Once the plastic has cooled, engineers can use tooling equipment such as CNC machines to remove excess material. If needed, they can perform an additional pressure forming step, which uses positive air pressure to push the plastic deeper into the crevices of the mold for added detail.
A wide variety of industries use thermoformed products, including the automotive, transport, aerospace, sports equipment, packaging, and medical industries. This process is also used for many other products featuring an industrial design.
Thermoformed parts manufacturers often want to produce high-quality products that are highly salable, with specific applications such as:
Many of these applications also rely on vacuum forming to create the completed product, along with other thermoforming processes depending on individual project specifications. Regardless of what’s needed for a given application, the thermoforming process is capable of meeting most requirements to optimize quality and efficiency.
