Top 5 Mistakes to Avoid When Using Vacuum Form Plastic Sheets

Choosing the Wrong Thickness
One common mistake when using vacuum forming sheets is selecting the incorrect thickness of the plastic sheet for vacuum forming. Using a sheet that is too thick can lead to incomplete forming or excessive material wastage.
Improper Heating

Improper heating of the Vacuum forming sheet can result in poor quality finished products. If the plastic sheet for vacuum forming is not heated to the right temperature, it may not form correctly or could cause uneven thickness.

Inadequate Mold Preparation

Neglecting mold preparation is another critical error. Ensure that molds used for vacuum forming are clean, well-maintained, and free of defects. Any imperfections on the mold can transfer to the finished product, affecting quality and functionality.

Ignoring Ventilation

Proper ventilation is crucial when using vacuum sheets for packing. Without adequate ventilation, air can become trapped, leading to bubbles or deformation in the final product.

Failing to Test Samples

Before committing to a large production run, failing to test samples can be a costly mistake. Always perform test runs with the vacuum forming sheet to verify that the material, heating, and mold setup produce the desired results.
