Puristusprosessi

Puristusprosessi, often translated as pressing process, is a fundamental industrial technique used to shape, form, or reduce materials through the application of mechanical force. This process relies on the principle of compression, where materials are subjected to high pressure between two or more surfaces. The specific design of the pressing equipment and the forces applied are tailored to the material being processed and the desired outcome.

In manufacturing, pressing is employed for a wide array of applications. It is crucial in metalworking for operations such as stamping, forging, and deep drawing, where sheet metal or billets are shaped into complex components. In the plastics industry, injection molding and compression molding utilize pressing to create intricate plastic parts. The wood and paper industries also employ pressing for processes like laminate manufacturing and the production of particleboard and paper products, where layers are bonded together under pressure.

The puristusprosessi can be categorized based on the type of press used, including hydraulic presses, mechanical presses, and screw presses, each offering different control over force and speed. The outcome of the process is often a material with altered physical properties, such as increased density, improved strength, or a specific form. Careful control of pressure, temperature, and duration is essential to achieve the desired product quality and avoid material defects.
