Thermoforming Sheet Thickness Knowledge
Why Sheet Thickness Matters
Proper sheet thickness is critical in thermoforming to ensure uniform wall thickness in the final product. Too thin and the material may tear or fail to properly form. Too thick and you waste material and increase cycle times unnecessarily. Our calculator helps you find the sweet spot for your specific application.
How Draw Ratio Affects Thickness
The draw ratio (depth/width) determines how much the material must stretch during forming. Higher draw ratios require thicker starting gauges to prevent excessive thinning in deep-drawn areas. As a rule of thumb, draw ratios above 1.5 require careful thickness calculation to avoid product failure.
Material Considerations
Different materials have different elongation properties. PET can typically handle higher draw ratios than PP at the same thickness. Always consult material specifications for maximum recommended draw ratios. Our calculator accounts for material properties in its advanced algorithms.
Industry Standards
This calculator is based on industry-standard formulas used by leading thermoforming manufacturers worldwide. It incorporates safety factors to account for variations in material properties and process conditions.

Our calculator provides estimates based on industry-standard formulas and typical material properties. For most applications, it will give you results within ±10% of the optimal thickness. For critical applications, we recommend physical testing with your specific material and mold configuration.
For products with varying depths, use the deepest section for your calculations. You may need to adjust thickness based on the most demanding area of your mold. In complex cases, consider using our premium consulting services for customized solutions.
Yes, the calculator works for both vacuum forming and pressure forming processes. Pressure forming may allow slightly higher draw ratios due to the additional forming force. For pressure forming applications, you can typically reduce the calculated thickness by 10-15%.
Different materials have different elongation properties. The calculator automatically adjusts for common materials like PET, PP, and PLA. For specialty materials, you may need to apply a correction factor based on the material's technical datasheet.
