Plastic thermoforming process can be defined as the process of taking a sheet of material that is made from plastic then heating it up until it get to a point that it is pliable and changing its shape to form a three dimensional object, this process is then finished up by trimming to make it become a usable product. There are a number of steps that one has to undertake here inoredr to make this process a success. The process of plastic thermoforming is as follows.
The first process to be taken is the design process. This is what will kick start the plastic thermoforming process. This is because they are usually used for larger production of plastic material. Here the design will be drawn to help come up with the shape of the plastic material. They will then be able to know how big or how small it is from the dimensions. They will be then be able to select the kind of materials to be used. Other than plastic as the main material others can only be used for aesthetic purposes. They can therefore be in a position of selecting the best plastic material to be used.
The second stage is always the one that is most demanding. First of all it goes through the tooling process. This will involve the process of creating the mold that the plastic material is to be heated on. This is what is known as tooling process. Plastic thermoforming uses aluminum molds and other materials may also be used depending on the size and complexity of material. With a mold at hand then the plastic thermoforming can now begin. This will involve the heating of the plastic material to a pliable temperature. Once the material is formed then the mold will be cooled and removed to give you the final plastic material that you wanted in its correct shape. To make sure that there is zero residual stress, the cooling process should be done under ambient temperatures.
Trimmimg is what remains with the final product at hand. It is the very last process that involves the very last touches. You will be trimming some parts of the product to help with removing the unwanted parts. This process is eiter done by hand or with the aid or ftobots. This generally depends on the size of the object and number of the object to be trimmed. This will then enable the plastic material to achieve that final shape that is desired. After this then secondary operations such as painting and packaging might come in if it is necessary.
