Applications in Medical Industry
Medical components are extremely demanding: in addition to sealing, strength, and cleanliness, process validation and stability play a vital role in production.
Housings of electrical components protect the functionality of the sensitive interior parts. Particularly with complex parts geometries, such as grip plates of surgery tools, ultrasonic welding provides solutions with dimensional accuracy and stability.
Laminating or perforating different materials for wound dressing so that they remain breathable, sterile and soft, which is possible with ultrasonics. Due to the low energy input, ultrasonic welding does not have any negative effect on absorbency and feel.
Tight and mark-free welding is possible with ultrasonics. The process fulfills absolutely all prerequisites, for example, required for blood and dialysis filters. Medical products, many lives depend on their correct functionality.
Lighting plastic enclosure requires good light transmittance, corrosion resistance, high temperature resistance, insulation, high melting point, thermosetting, stable in nature, good plasticity and so on, so the standard is very high in the production process. Ultrasonic technology in the production of most lighting products have a very good effect on the welding.
Light sensing, inductive and capacitive sensors are used in a wide range of applications in all areas of automation. In addition to perfect appearance and no scratches, ultrasonic welding meets sealing and reliable functional requirements.
In addition to being suitable for household appliances, it is also suitable for outdoor machines and equipment. Typical applications for ultrasonic welding are the production and welding of horticultural appliances, functional components and underwater roofing coils.
Household appliances, as appliances that are used every day, must be strong and durable. This necessitates the safety of the integration of electrical and electronic components. Ultrasonic welding is especially suitable for the connection of complex household appliances such as irons or operating panels.
Sealing, pressure resistance and functionality are not compromised: Ultrasonic welding meets these requirements for automotive components in the engine compartment. In the filter, the filter material must be welded firmly and must have high temperature and low temperature properties.
High strength, tightness and dimensional accuracy, and the appearance of no scratches and indentations are typical requirements. Ultrasonic welding protects the function of the part and enables the welding of complex shapes.
Ultrasonic welding of these components ensures that the functionality of the built-in functional components is not limited. 100% inspection and recording of all welding parameters. The semi-permeable membrane acts as a pressure balance element (DAE) and can be simultaneously punched and sealed using ultrasonic waves.
In PET applications, ultrasonic energy quickly reaches high melting points and increases throughput. Sealing and separation of the blister can be achieved, and the opening and authentic anti-counterfeiting functions can also be easily realized.
Ultrasonic welding is especially suitable for coated cardboard packaging materials. Although the product is wet, it still guarantees the sealing of the weld, and whether it has an aluminum film has no effect. The nozzles can be integrated normally. The sealing time is short and the output is high. Repeatable welding parameters ensure consistent seal quality.
Ultrasonic energy allows safe separation of residual products in the weld area to ensure absolute sealing. This significantly reduces the number of package leaks and enhances product durability. Lingke Ultrasound fully demonstrates this advantage in longitudinal continuous welding and lateral intermittent welding of stand-up pouches, zipper bags and hose bags.
Topsheet and acquisition distribution layer are joined at high speeds. Due to targeted energy input on ultrasonic weld spots optimum wear comfort is achieved. Ultrasonics guarantees high strength and simultaneous soft feel, also for fixation of sanitary napkin wings or finishing of textile edges.
Shape-welding is required i.e. for single-use hand mittens in different variations. The product remains soft and smooth without rough edges and at the same time maximum layer adhesion is guaranteed. Cutting with ultrasonics is fiber-free and results in clean, distinctive cuts. Moreover, soft surfaces are not damaged during ultrasonic embossing. More on this application
Producing diapers without any solvent-containing adhesives has become a tangible dream! By now, it is possible to perform every single manufacturing step for production of diapers using ultrasonics. All ultrasonic processing steps for production of diapers have in common that the resulting hand feel is very good and tightness of the diaper is ensured.
Print cartridges or writing utensils are consumer products which are produced in large quantities. Ultrasonic welding is a cost-effective and fast joining technology ensuring tightness and reliable function of the products.
