It’s likely that foam that is cut to size is probably taken for granted. Whether it is being used for stuffing in sofa cushions and pillows, or as a material to protect delicate objects in transit or electronic devices. We seem to accept that the foam will be shaped and cut to the exact size of the object to be protected. However, if one were to consider this point for a moment, an obvious question might be, how is this precision achieved?
Take, as an example, a holdall or carry case that is designed to hold and protect a laptop computer or a net book. In order to ensure the device does not move around while being carried by its owner, the surrounding foam must ensure a snug fit. There are new devices coming onto the market every year, laptops that have larger screens but are thinner and lighter, for instance. Net books have also grown in popularity due to their versatility, surprising battery capacity and the fact that they are less bulky than their cousins.
Foam, like the laptop or net book, is very lightweight which makes it easy to fit inside a holdall. Companies such as we at Technical Foam Services also have the expertise and experience to cut the foam to size in order to accommodate the laptop or net book.
One of the most favoured methods of achieving this precision is known as hot wire cutting. This particular process involves the use of blades that oscillate in both vertical and horizontal directions. The result of this process is a very precise and even cut. The operation itself is versatile enough to be equally effective in the cutting of both rigid and pliable foam.
Another equally efficient way of cutting foam is the use of powerful jets of water
