These intricate, relief-like patterns are achieved through the embossing process, which is essential for adding both aesthetic appeal and functional textures to materials. How Embossing Works Embossing involves creating raised or recessed designs on a material’s surface. To achieve this, the material is first heated, allowing it to become pliable enough to adopt new 3D patterns. Once heated, the material is passed through an engraved roller, which imprints the desired texture. As the material cools, it retains the embossed design, creating a durable and visually appealing finish. In the production of large-scale, multi-layer plastic textiles—such as synthetic leather, tarpaulins, and floor coverings—heat plays a crucial role at various stages. The final embossing step is particularly important, where the surface structure, like the grain of faux leather, is created. Precise temperature control is critical to ensure a uniform pattern across the entire width of the material. Leister’s KRELUS IR heater field, designed modularly with individually controllable heater groups, delivers precise and consistent surface temperatures, ensuring optimal embossing results.

In the final step, Process Heat is used to make various products shine or otherwise refine them, such as roasting. The shine on chocolate or on cosmetic products such as lipstick is often created using hot air blowers. Hot air can even be used to gently process, i.e. roast, coffee beans. Hot Air Treatment In the manufacturing of lipsticks, the various substances such as wetting agents, mostly consisting of a plant-based gel; wax such as carnauba or beeswax; and pigments, often made from iron oxide, are mixed together and melted. In one of the last steps of the shining process, the surface of the lipstick is heated with hot air generated by a hot air blower. This gives lipstick its characteristic, seductive shine before it is closed with a lid and finally packaged. In chocolate pralines the ingredients are different, but the process in the production line is the same. Hot air blowers are used to slightly heat the matte chocolate surface, giving it a shiny finish. <img loading="lazy" decoding="async" width="603" height="336" src="https://weldheat.com/wp-content/uploads/2021/10/6-1.png" class="attachment-large size-large wp-image-2420" alt="" srcset="https://weldheat.com/wp-content/uploads/2021/10/6-1.png 603w, https://weldheat.com/wp-content/uplo…

There are two main areas for this: Heat shrinking in packaging technology and heat shrinking in electrical engineering. Shrink films are often used for packaging. Basically, these are films stretched in the manufacturing process, which contract to their original shape when heated due to the so-called memory effect. Shrinking packaging film In the food and beverage industry, a tubular shrink film is usually placed around the product to be packaged. When it is subsequently heated with hot air, the film contracts until it is tightly wrapped around the packaged product. This process is used for small products, such as lipsticks, as well as entire pallets that have been loaded with goods. Hot air shrinking is also widely used in beverage packaging applications. Instead of having a label applied to them, individual bottles are often wrapped in a decorative “sleeve.” This may only cover part of the bottle or even extend through the entire height. Another typical application is the use of shrink film to create a pack that ranges from six to 24 bottles or cans. Shrink-on caps are placed over the opening of wine bottles (screw tops or corks) to protect them against contamination, as well as decorative purposes. When these preformed caps are exposed to hot air, they shrink tightly around the neck of the bottle and closure. Packaging an…

These devices are used in various drying applications. Examples of drying applications can be seen in the manufacturing of paper, textiles, nonwoven material, metals, plastics, and glass components, in film packaging, and in other applications related to foodstuff such as roasting coffee or drying fruits and vegetables. Drying in Processing Users can vary the air distribution and flow rate according to the desired drying results. This involves adapting parameters, such as the temperature and air volume, and utilizing different nozzles. Drying with hot air causes two physical effects to occur at the same time. Together, they further increase the efficiency of the drying process. Firstly, hot air can hold considerably more moisture than cold air. Secondly, the continuous current of air that passes over the wet surface increases the rate of evaporation, particularly if fresh, dry air is always used. To make the drying process even more efficient, hot air is often used to blow off any stray drops of moisture on the surface before drying begins. Leister has a solution for this too, offering a blow-off nozzle specially developed for this purpose and the powerful AIRPACK blower. <img loading="lazy" decoding="async"…
