Vacuum forming is a widely used thermoplastic molding method that involves heating a polymer sheet until it becomes malleable, then using vacuum pressure to mold it over a pre-formed mold.
Vacuum Forming Procedure
To mold a vacuum-formed product, the plastic sheet is first mounted into a frame and heated until it becomes pliable. Once the material is ready, it is positioned over a mold, and a vacuum is applied to draw the material tightly over the mold, achieving the desired shape.
After forming, the material is hardened to retain its shape. The final product is then cut to remove unwanted material and processed for use.
Applications of Vacuum Forming
Vacuum forming finds its benefits in sectors such as retail for creating durable plastic parts. Some frequent products made using vacuum forming include:
- Automotive parts
- Plastic packaging
- Medical device casings
- Point-of-sale stands
Benefits of Vacuum Molding
One of the biggest pros of vacuum forming is its low production cost. Other key benefits include:
- Rapid production
- Low-cost tooling
- Flexibility in design
- Strength-to-weight ratio
Conclusion
For businesses looking for an affordable plastic manufacturing solution, vacuum forming provides a practical option.
