Thermoforming is a plastic molding technique, that results in a variety of highly usable products.
A plastic sheet is heated to a pliable temperature in an oven, it is stretched and formed in a mold and then cooled to a finished shape.
Thermoforming is grouped into two categories depending on the sheet thickness of the formed part. They are:
● Thin gauge thermoforming
● Thick gauge thermoforming.
The thermoforming process involves three basic steps.
1. heating the plastic sheet
2. Forming the plastic sheet
3. Trimming and finishing it into a usable product.
The methods by which the forming steps are accomplished can be classified into three basic types:
▶ Vacuum thermoforming
▶ Pressure thermoforming
▶ Mechanical thermoforming
