What you need to Understand about Plastic Thermoforming Process

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. In order for this process to become successful then there are a number of processes that the product have to go through till the end of the process. The following is how the process works out.

Design process is the first step that is always taken. This is what will kick start the plastic thermoforming process. This is because they are usually used for larger production of plastic material. At this point the designs that are drown are the ones that will determine the shape of the final product. They will then be able to know how big or how small it is from the dimensions. They will then be in a position where they can select the materials to be used. The material is plastic but they can add some other material just for aesthetic reasons. They will also be able to know which kind of plastic material is best to be used in his case.

The second stage happens to be the most demanding one. 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. 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. The plastic thermoforming can only begin with the mold at hand. 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. The cooling process should be done under ambient temperatures to ensure that there is zero residual stress.

When you are done with all this what you will have left to do is trimming of the final product. It entails working on the last touches on the final product that you’ve got. You will be trimming some parts of the product to help with removing 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. After this then the plastic material will be having the desired shape that it should have. After this then secondary operations such as painting and packaging might come in if it is necessary.
