Stages Involved in Plastic Thermoforming


Plastic thermoforming is 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 following are these steps involved in plastic thermoforming.

Design process is the first step that is always taken. This is what will kick start the plastic thermoforming process. In most cases this will involve the production of very many plastic materials. At this point the designs that are drown are the ones that will determine the shape of the final product. At this point in time dimensions have to be put into consideration to make it possible the size of the plastic material. 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. Thay will also be able to know the best kind of plastic material that they will use.

The second stage is always the one that is most demanding. At this point they will start with the tooling process. This involves the creation of the mold that the plastic material will be heated to. This is what is known as tooling process. In plastic thermoforming, aluminum molds are the ones that are usually used but other materials can also be used in making molds depending on the size and what is needed. With this at hand then the real thermoforming will now be able to begin. This will involve the heating of the plastic material to a pliable temperature. Once this process is done then the mol can now be cooled off then removed to give us the plastic material wanted with the desired shape and size. The cooling process should be done under ambient temperatures to ensure that there is zero residual stress. Learn more about this website.

With the final product at hand the only thing that remains is trimming. This is the last process that is usually involves doing the finishing touches on it. This will involve doing the trimming of some of the original material and also some of the unwanted parts. This can either be done by hand or some robotic machines can also do it. It will all depend with the size and the number of objects that are 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.
