lämpöpuristus

Lämpöpuristus, also known as heat pressing, is a manufacturing process that involves applying heat and pressure to bond materials together. This technique is commonly used in various industries, including textiles, plastics, and composites. The core principle is to melt or soften one or more layers of material, allowing them to fuse into a cohesive unit when cooled under pressure.

The equipment used, a heat press, typically consists of two heated plates or platens. One platen is stationary, while the other can be moved to apply pressure. The temperature and pressure applied are critical parameters, varying depending on the specific materials being processed and the desired outcome. The duration of the heat and pressure application also plays a significant role in achieving a strong and durable bond.

In the textile industry, heat pressing is widely employed for applying heat transfers, heat-sealable films, and for creating permanent creases or pleats in fabrics. In plastics manufacturing, it can be used for welding sheets of plastic together or for molding plastic components. For composite materials, heat pressing is often used to consolidate layers of reinforcing fibers and resin, ensuring uniform distribution and strong adhesion. The process offers a precise and repeatable method for creating durable bonds with controlled properties.
