Product Selection Differences for Thermoforming and Vacuum Forming
Thermoforming and vacuum forming are both popular processes used in the manufacturing industry for creating plastic products. Here are some key differences to consider when selecting between the two options:
Thermoforming: 1. Process: Thermoforming involves heating a plastic sheet until it is pliable and then forming it over a mold using pressure. 2. Heating method: Thermoforming typically uses infrared heaters, hot air, or other heating methods to heat the plastic sheet. 3. Pressure: Thermoforming typically requires both positive pressure (air pressure) and possibly vacuum pressure for more complex shapes. 4. Tooling cost: Thermoforming generally has higher tooling costs due to the need for molds. 5. Suitability for complex shapes: Thermoforming is suitable for creating more complex parts and shapes with undercuts.
Vacuum Forming: 1. Process: Vacuum forming involves heating a plastic sheet until pliable and then using vacuum pressure to mold the sheet over a form. 2. Heating method: Vacuum forming commonly uses infrared heaters to heat the plastic sheet. 3. Pressure: Vacuum forming relies mainly on vacuum pressure to mold the plastic sheet over the form. 4. Tooling cost: Vacuum forming generally has lower tooling costs as compared to thermoforming due to the simpler molds required. 5. Suitability for simple shapes: Vacuum forming is suitable for creating products with simple shapes and shallow draws.
In summary, thermoforming is more suitable for creating complex shapes and typically involves higher tooling costs, while vacuum forming is more cost-effective and suitable for simpler shapes. The choice between the two processes will depend on the specific requirements of your project in terms of complexity, cost, and desired end product.
