The use of plastic objects and containers is now a daily part of our life. Majority of the objects we are surrounded by having some plastic components attached to it or are under direct use. The fact that plastic is such an integral part of our life makes us think that how are they actually shaped and moulded into objects for our use.
Plastic and other polymers are moulded through different techniques of plastic moulding process which shapes and defines the objects according to desire. Since the 1800s, the industry of making plastics has been growing and increasingly contributing to other industries as well. Through its various techniques, it is able to make different products which are durable and sturdy and can be comfortably used.
One of such rapidly applied techniques is vacuum forming. This is a process is a more simplified version of thermoforming. Here, the plastic is heated into forming temperatures and pressed against a mould from one side. Then it is pressed to take the shape of the mould because of the pressure of vacuum being applied from the outside. It is a much easier process which is not labour-extensive and can also help in producing in large-scale or for masses. This process was identified in the 1930s where the process made it even easier to produce products with less effort.
Why Is the Process So Important or Relevant Today?
Large vacuum forming companies have emerged since the method was identified and are excelling rapidly. There is no alternative for this low cost and easy method of production. The whole process of moulding plastic has become more cheap, fast and flexible. When compared to the injection process, vacuum forming is more cost-friendly and the tools are produced at quite a fast rate. Since its innovation, there is no stopping to this method. Large vacuum forming technologies are being combined with various other technologies like 3D printing, ink moulding and so on to provide new products. Collaborations with renowned brands and institutions are only signing that great innovative products are here on its way to make man’s life easier and more sustainable.
Primary Use or Application of Large Vacuum Forming Products
The products that are developed out of vacuum forming process for low volume manufacturing are generally used in place of complex-shaped components that are built out of fabricated metal sheet. Such kind of conversion is generally seen especially in air distribution ducting systems. Such fabricated metal sheet products require heavy work operation, more inclined towards welding, grinding, and finishing. Similarly, if vacuum formed products are compared to other plastic forming techniques and operations like resin transfer and so on, the vacuum formed parts are more likely to be favorable because of their quality and the fact that they are cheap for such a durable product. This is the reason why so many low volume manufacturers prefer large vacuum forming products and operations.
Vacuum forming Products applicable for low volume manufacturing is ideal for various applications. Some examples are given below:
- Medical and Healthcare
- Consumer Products
Some Other Associated Benefits of Large Vacuum Forming Products for Short Runs:
- The products are highly detailed and are available in all shapes and sizes.
- Substantial reduction in equipment costs as large parts now does not require high weight presses as it is required for injection molding.
- Can be modified according to consumer’s needs and the material and appearance according to customer preference.
- Flexible when comes to tooling design
So these are the little things to keep in mind for the same.
