Vacuum Pressing Process Working

The intention of a vacuum heat press is to shape a piece of plastic or similar polymer into an exact form with the help of a single-surface mould and a vacuum. This is actually a variant of a process known as thermoforming. Once the sheet of plastic is put into place, the vacuum membrane press machine will begin with a thin sheet of a thermoplastic (such as polystyrene). After it is heated, it is forced against a specific form. A vacuum will then remove any existing air trapped within a cavity; forcing the thermoplastic to conform to an intended shape. Once the plastic cools, it is removed.

Applications of Vacuum Pressing Systems

There are numerous industries which employ the use of a vacuum press table. Some common items that can be made include automated teller (ATM) machines, medical diagnostic equipment, engine covers and even dashboards. However, another interesting application can be seen in a woodworking vacuum press. In this instance, a vacuum is applied to the surface of the wood. As more than 1,000 kilograms of pressure per square foot is often possible (depending upon the model), this is an excellent way to force veneer into the porous surface of the wood. In fact, the liquid will penetrate much deeper and more uniformly than with traditional methods. Although this is not as common as the previously mentioned thermoplastic processes, it is still a valuable tool to possess.
