Stages Involved in Plastic Thermoforming
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. 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 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. In most cases this will involve the production of very many plastic materials. The shape of the final product will be determined by the designs that are drawn when the process of plastic thermoforming starts. At this point in time dimensions have to be put into consideration to make it possible the size of the plastic material. This will then allow them to select the materials that are to be used. The material is plastic but they can add some other material just for aesthetic reasons. Thay will also be able to know the best kind of plastic material that they will use.
At this particular point in time the plastic thermoforming goes through the most demanding process of all. At this point they will start with the tooling process. This involves 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 involves heating the plastic material to a pliable temperature. Once thisis ready then the mold can now be removed than after it has been cooled off. The desired plastic material will then is gotten and get ready for use. To make sure that there is zero residual stress, the cooling process should be done under ambient temperatures.
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. 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. This will depend with the size and number of objects that are supposed to be trimmed. At this point then the plastic material will be having the desired shape that it was ,meant to have. After this then there can be some secondary operations involved if need be and they are namely packaging of the final product and painting.
