• Surgery Instruments & Functional Components

    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.

  • Wound Dressing & Bandaging Material

    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.

  • Medical Containers

    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.

  • Decorative Lighting

    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.

  • Cables and Plugs

    Plugs and terminal blocks are used as high value safety components in electronics, electronics and electrical installations. The stable connection of the contacts ensures that the contacts are not offset and the current is stable. Similarly, the connection of no material can also be achieved by ultrasonic welding.

  • Electrical Devices

    It is also possible to solder and rive electronic components outside the cover and display. Ultrasonic welding technology can be used to introduce energy into the weld zone in a targeted manner, ensuring a secure connection between the support plate and the cover without threatening sensitive electronic components.

  • Sensors & Switches

    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.

  • Computer Peripheral

    In addition to the computer itself, all devices except the U disk, mobile hard disk, speaker, headset, wrist support, USB extender and other output input devices are computer consumables. Ultrasonic plastic welding greatly improves the efficiency of computer consumables production and reduces the rate of defective products.

  • Communication Consumable

    Communication supplies include telephones, fax machines, walkie-talkies, mobile phones and other communication tools. Many products' outer casings and internal components prouction use ultrasonic plastic welding equipment and technology, which greatly saves labor costs, improves production efficiency, and has high product quality.

  • Printer Consumble

    Toner cartridges and ink cartridges are the core components of the printer and are of very high quality. The overall sealing and precision cannot be neglected, and the interior is also clean.

  • Small Household Appliances

    Electronic appliances can be seen everywhere in daily life. In the production process, it is necessary to ensure the safety of the integration of electrical and electronic components and not cause secondary damage to the product itself. Ultrasonic welding can meet the higher requirements of production standards and greatly improve production efficiency.

  • Gardening

    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 Electric Appliances

    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.

  • Engine Components

    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.

  • Exterior & Lights

    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.

  • Functional Compartment

    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.

  • PET Packaging

    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.

  • Beverage Soft Packaging

    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.

  • Film Packaging

    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.

  • Feminine Hygiene Products

    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.

  • Makeup and Personal Care Products

    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

  • Baby Hygiene Products

    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.

  • Stationery

    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.

  • Toys

    In order to comply with rigorous safety standards for toys, strong and reliable connections are indispensable. To prevent injury hazards, the requirements for good feel must be met.
    Ultrasonic welding ensures flawless and temperature-resistant connections without the use of adhesives.

  • Surgical Instruments Cleaning

    n addition to conventional surgical instruments, there are also some specialized instruments such as orthopedics, orthopedics, and brain surgery. Surgical instruments have high standards for cleaning and disinfection. Ultrasonic cleaning equipment greatly improves the efficiency of work and enhances the cleaning effect.

  • Daily Supplies Cleaning

    Jewelry, jewellery, glasses, etc., are tarnished for a long time and contain a lot of bacteria. Ultrasonic cleaning acts on the liquid, and the bubble in the liquid ruptures to generate shock waves to clean and flush the inner and outer surfaces of the workpiece, so the cleaning effect is excellent and does not hurt the product itself.

  • Precision Hardware Cleaning

    Precision hardware refers to the metal processing category with high precision requirements, including precision plastic hardware, precision stamping hardware, etc., which are widely used in electronics, watches, aviation and other industries.
