Roller Feeding Unit
The foil or packing material is supplied from this roller feeding unit and it is adjusted according to the material width. It is essential to note the movement of this roller as it can cause poor thermoforming if not supplied properly.
Oven or Preheater
Preheater or an oven is the initial component in a thermoforming machine. It heats the sheet and stretches it according to the shape of product to ensure easy molding.
When the sheet or film gets heated it enters the second stage where thermoforming molding units are present. These units are responsible for easy manipulation of plastic sheet according to the size of product. Both the male and female molds press the sheet and make the desire lid, tin or cover.
As the material is completed the products are then taken off by a pickup platform and collected at the end.
During the thermoforming process the sheets that are of no use or are scrap are removed by the scrap removal unit. The scrap is then recycles and used as a thermoforming material.
4.What types of Thermoforming Machines are available globally?
Types of Thermoforming Machine
Depending upon the operation, there are three types of thermoforming machines available in global market.
Mechanical Thermoforming Machine
In a mechanical thermoforming machine the sheet or plastic after heating is clamped in a molding unit and pressed by both male and female mold. In this type the products produced are much well defined and of high quality as compare to other two types.
Vacuum Thermoforming Machine
In a vacuum thermoforming machine, the stretching of thermoforming plastic is done using a vacuum system on molds. Air is evacuated from the surface to achieve vacuum effect. This also is a great advance form of thermoforming but limits where the vacuum pressure is not obtained.
Pressure Thermoforming Machine
As the name explains, pressure is used for stretching of material in this type of thermoforming machine. The upper and lower side of the mold contains air pressure that stretches the heated material to achieve high quality and precise design.
5.What is the working principle of a Thermoforming Machine?
Working Principle of a Thermoforming Machine
The working principle of a thermoforming is quite simple. Following are the steps involved in a thermoforming process.
- Initially the sheet or foil present on the roller is feeded using a feeding unit to the oven or preheater.
- Here the sheet is heated to a certain temperature that accurate molding of material can be performed.
- The sheet is then sent to the molding unit where the sheet is stretched either mechanically or through vacuum or air pressure. The sheet gets adjusted to the shape of mould and then both the male and female parts force it to achieve the desire shape.
- The product is then supplied to the output unit through a conveyer system where it the cropping of extra mould is done and after then the packing process is carried out.
- The process is too fast that thousand of products are formed in a day and also recycling of waste material is done.
