platenpersen

Platenpersen, or plate presses, are a class of machine presses that operate by bringing together two flat surfaces, called platens, to apply pressure to a workpiece. They are used to transfer images, shapes, or textures from a plate or die onto a substrate, or to laminate, emboss, or form materials.

There are several variants of platenpersen. Manual bench presses rely on a hand lever to close the platens, while hydraulic, pneumatic, or motorized presses use fluid pressure or electricity to achieve the closing force. The size ranges from small craft tools to large industrial machines. The platens may hold printing plates, dies, laminates, or textures relevant to the intended process.

Typical applications include printing and reproduction (notably letterpress and hot foil stamping), embossing and debossing to create raised or recessed patterns, lamination of films or papers, and forming or bonding thin metal, plastic, or composite sheets. In some setups, platenpersen are used for die-cutting, riveting, or assembling components where flat, even pressure is required.

Key components usually include a rigid frame, a lower platen (bed), an upper platen (ram), and a driving mechanism to bring the platens together. Safety devices, controls for pressure or stroke, and alignment aids are common. Maintenance involves regular lubrication, inspection of platens for wear or misalignment, and ensuring hydraulic or pneumatic systems are leak-free and properly vented.

Platenpersen are valued for delivering uniform pressure over a flat area and for versatility in small-scale production, prototyping, and crafts, as well as in some industrial finishing processes.
