The process of creating a plastic part with a pressure-forming machine begins with the plastic sheet clamped in the oven and a mold or mold chosen. The heated plastic forms a seal around the mold, and a finished part can be seen on the machine. The problem with pressure forming is that the plastic sheet can be stretched too thin, which can cause it to crack. This makes the product too weak for some projects. To avoid this problem, a plug assist is used to prevent the material from becoming too thin. Plug assists will pre-stretch the material, minimizing the likelihood of thinning.
The process is also used for the production of recessed sidewalls and a significant third dimension. Many manufacturers choose pressure forming for parts that have an inverted return lip or recessed sidewall. The cost of tooling can be up to 90% less than the cost of a plastic injection-molded part. Because of the high quality of the finished product, pressure forming is often a cost-effective alternative to injection molding.
The process is also very versatile. Because of its versatility, pressure-forming machines are able to make parts that are suitable for many different configurations. A manufacturer can easily add or remove styling features, logos, or model designations, as desired. Additionally, a pressure-forming part can create a variety of openings or ports, which are important features of any car or truck. Because of the precision of the process, pressure sintering is the preferred method for making automotive parts, and it is also a highly cost-efficient alternative.
A pressure forming machine is an excellent option for producing plastic components. In addition to producing recessed sidewalls, pressure forming is a great choice for parts with undercuts, inverted return lips, and recessed sidewalls. The cost of tooling is much lower than the cost of plastic injection molding, so it is a viable option for low-volume production runs. This method is also highly efficient and can produce a wide range of high-quality parts.
It is easy to modify the pressure forming tooling for different types of products. A manufacturer can produce a part with a different style by simply changing the tooling. It is also possible to create parts with port openings and other intricate details. This process is often the preferred method for a high-quality plastic component. The most important advantages of a pressure forming machine are: it can produce complex shapes and it is cheap to use.
A pressure forming machine is a cost-effective alternative to injection molding and is very precise. It has several advantages over vacuum forming. It is easier to design and makes the product crisper. A good thermoformer should also be able to make small adjustments on the part. Once the parts are created, they can be easily replaced and the process repeated over. This makes the whole process more efficient. A pressure forming machine can be a very useful addition to any assembly line.
