ultrasonic welding plastic materials

Base materials used for the parts Material (base material) selection also plays an important role in the ultrasonic welding process. Ultrasonic welding is a widely recognized and accepted process for joining thermoplastic materials. It is commonly used for plastics and metals, and especially for joining dissimilar materials. Ultrasonic welding is cost effective and a green technology. Every ultrasonic bonding operation will vary based on the plastic materials being joined, the shape of the workpieces, and other factors. The company is ISO 9001 certified and is consistently in the vanguard of industry innovators. Trade shows are a platform for direct exchange – we show you our latest developments and state-of-the art technology. Customer benefits are always our paramount goal. Ultrasonic welding qualifies as the best suitable joining technology: Using ultrasonics, consumer components can be produced and joined in a cost-effective way; at the same time, the process provides great flexibility in terms of design. Toll Free: (888) 634-1143. Let's talk business! Longitudinal vibrations in frequencies of 20 kHz, 30 kHz, and 35 kHz with tool amplitudes between 5 µm and 50 µm are introduced into the plastic materials under the action of force. Since its inception in 1969, Sonics & Materials, Inc. has enjoyed over 5 decades of world leadership in the fields of liquid processing and ultrasonic welding, sealing and cutting technology. Plastics assembly is a fast, clean, efficient, and repeatable process that consumes very little energy. Kerry Ultrasonics was formed in 1954 and had been a prominent manufacturer of plastic welding and ultrasonic cleaning equipment. Phone: (714) 630-9530. The following drawings illustrate the basic principle of ultrasonic welding. Click here for technical project management. Reach Us. Ultrasonic welding works extremely well with a range of thermoplastics, but some are incompatible with each other or with the process, so choose with care. At Herrmann, optimization means to focus on continuous and long-term improvements: in manufacturing, for process sequences, in service, in education or with regard to partnerships. For example, ultrasonic welding is used to make electrical connections on computer circuit boards, and assemble electronic components such as transformers, electric motors and capacitors. Click here for laminating of nonwoven materials. t: 01793-641040  Reg. We provide comprehensive solutions for your welding and joining tasks - made in Germany. State-of-the-art ultrasonic welding machines and most recent measuring and testing equipment in our laboratories worldwide. It offers many advantages, including process reliability and repeatability, lower energy usage than other joining techniques, material savings (because there is no need for consumables, such as glue or mechanical fasteners), and labor savings. In general, rigid plastics exhibit excellent far-field welding properties because they readily transmit vibratory energy. More basic knowledge on ultrasonic sealing of packaging and examples for applications. To weld different materials, they need similar molecular structures - crystalline ones are only weldable to themselves. Ultrasonic plastic welding is suitable for virtually all thermoplastics. Click here for sealing of packaging materials. Once cooled down a solid homogeneous weld between the 2 parts is created. In addition to welding, ultrasonic energy is commonly used for processes such as inserting metal parts into plastic or reforming thermoplastic parts to mechanically fasten components made from dissimilar materials. Only together can we move forward and set new milestones. These vibrations are called ultrasound because they are at a frequency above than the hearing capacity of the human ear (greater than 16 kHz). In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the … To ensure your production is running smoothly. Our workshops range from basics seminars to in-depth expert knowledge, and always provide practical orientation. Ultrasonic welding uses high-frequency vibration to melt and weld plastic. Sheet sections of thermoplastics – the parts to be joined - are placed in a V-butt or T-butt position with a consumable plastic welding filler rod that must be the same or similar material at the joint area. To give you help with ultrasonic welding of plastics for your application, this ultrasonic welding guide lists the most common unfilled grades of plastic available & their suitability for each style of ultrasonic welding  As a rule, stiffer materials are easier to weld & those with higher melt temperatures need more energy.
