Vacuum molding may not be a new term, but the meaning of this term is not as popular as the term. Many people are not knowledgeable of what this means and how this might be of help. Vacuum molding is a process of shaping plastic into different shapes and this is undoubtedly the best way to make various plastic products that are used in households and businesses. This process is a type of thermoforming, which heats up a sheet of plastic to the degree where the plastic becomes malleable.
Heating of the plastic sheet is done with the help of aluminum sheets as well as heaters that use infrared technology. Heating is done from both the top as well as from down in order to ensure uniformity of heat as this will yield superior results. After the heat reaches the appropriate temperature, the plastic sheet gets molded due to the vacuum and results in the final product. The vacuum provides an airtight environment and this offers a better situation for the effective molding of the plastic sheet. The appropriate temperature varies depending on the thickness of the plastic sheet being used. One important thing that is to be borne in mind while setting up processes of vacuum molding is that the plastic will slightly shrink as it starts getting cool.
Pressure Forming is a type of manufacturing process used for molding plastics in to different pre-determined shapes. By using pressure forming, a plastic sheet that is already heated is forced to take a concave mold shape. After this, air which is compressed is forcibly sent into the heated plastic sheet and this would force the plastic to take the shape of the mold. There are a wide variety of vacuum formable sheets of plastic are available in the market in different thicknesses. Thus, it is necessary to understand how each variety of sheet works when used for molding and is exposed to pressure. Also, there might be a need for a little amount of trimming to the finished plastic product.
There is a possibility of creating a plethora of plastic products using this method of manufacture. Children’s products, in particular, are made using this process. The molds used in this process help in creating a wide number and variety of products. Moreover, another advantage of using this process is that the speed at which one can make products is extremely surprising as products can be made very swiftly.
