When it comes to durability, efficiency, convenience, stability, usefulness, we use plastics for our purposes. And, there are different kinds of plastics used for everyone’s convenience. They are tough, reliable, durable, helpful and also easy to use. Plastics cost less than other products in the market and Thermoforming has been a part of it.
Through thermoforming, a plastic sheet or film can be easily softened up when heated and vice versa, it becomes hard again when it cools down. The plastic used in thermoforming can go through melting and freezing without altering its chemical state, and it can also be reprocessed.
The plastic sheet is heated between specialised heaters to form the product with its usual temperature. Later, the sheet is placed in a temperature regulated metal table or moulder until it gets cooled down. The plastic formed from the sheet is taken out of the sheet.
This procedure is applied to form plastic used for computers, machines, and other special equipment for electronics, medical, and industrial products.
Thermoforming has the following advantages:
• Easy to carry out
• Takes less time for production
• Lower costs of production
However, there are some disadvantages when using thermoforming:
• Thermoforming is quite expensive. Compared to other methods like injection moulding, this method can cost up to 50% more.
• Large plastic sheets are used in the method. They have to be fed into the rollers again and again. It leads to lots of extrusions.
• The plastic sheet will be stretched in this method. So, the products formed using a thermoforming break at a certain temperature.
• More plastic would be consumed in this method when compared to other methods. Nearly 10 to 20% more plastic is used to make any product in this method. It adds to expenditure and creates broad wastage too.
