Heating is the second step in the vacuum forming process. During this stage, the plastic sheet is heated from both the top and bottom before forming begins. The material is heated to a temperature between 170 and 210 degrees Celsius to make the sheet flexible enough for shaping.
The heating process affects how the material behaves during forming and helps prepare the sheet for the next stage of the process.
Different materials and component designs can require different heating conditions depending on the intended application and product requirements.
In vacuum forming, controlled heating helps prepare the material for forming while supporting consistent shaping across different component sizes and geometries.
Heating conditions can also vary depending on material thickness, component shape and the characteristics required for the finished product.
Once the material reaches the correct temperature, the sheet is ready for the next step in the vacuum forming process.
Proper heating helps the material become flexible enough for shaping while maintaining the characteristics required for the finished component.

In vacuum forming, a plastic sheet is heated until it becomes pliable, then it is sucked onto a mold using vacuum to take its shape
The tool is placed in a vacuum forming machine.
The sheet is heated from both the top and bottom to a temperature between 170 and 210 degrees Celsius before forming.
The warm and soft sheet is inflated, and the forming tool is raised toward the plastic material.
With the help of vacuum, the plastic material is shaped over the forming tool.
After cooling, the tool is lowered, and the product is then ready for post-processing.
