Vacuum forming is a widely used thermoplastic molding method that involves heating a polymer sheet until it becomes malleable, then applying vacuum pressure to form it over a custom mold.
Step-by-Step Vacuum Forming Process
To create a vacuum-formed product, the plastic sheet is first placed into a frame and heated until it becomes pliable. Once the material is ready, it is draped over a mold, and a vacuum is applied to pull the material tightly over the mold, ensuring the intended shape.
After forming, the material is solidified to retain its shape. The final product is then trimmed to remove unwanted material and finished for use.
Where Vacuum Forming is Used
Vacuum forming finds its applications in industries such as aerospace for creating customized plastic parts. Some common products made using vacuum forming include:
- Automotive parts
- Blister packs
- Healthcare packaging
- Point-of-sale stands
Advantages of Vacuum Forming
Vacuum forming is a simple method for producing high-quality plastic parts with minimal initial investment. Other significant benefits include:
- Fast manufacturing process
- Low-cost tooling
- Flexibility in design
- Strength-to-weight ratio
Final Thoughts
For businesses looking for an affordable plastic manufacturing solution, vacuum forming delivers a valuable option.
