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. Hot Gas (Air) Welding: Hot gas (or hot air) welding, is a technique that uses heat. Ultrasonic welding is whereby high-frequency ultrasonic acoustic vibrations are applied to two components being held together under pressure to create a solid-state weld. We supply you with a full-service package, including short response times. Customer benefits are always our paramount goal. It is always the people who make the difference in a company. These vibrations are called ultrasound because they are at a frequency above than the hearing capacity of the human ear (greater than 16 kHz). 01661446  VAT GB 348675511 Privacy Policy. Worldwide. This is about working together based on our values and about our mission to apply these values in our daily work. Vibrations are turned into heat and thus the plastic material melts, which results in a homogeneous joint. PC, PMMA, and ABS can be welded to one another under certain conditions. Trade shows are a platform for direct exchange – we show you our latest developments and state-of-the art technology. These include many parts made of thermoplastic materials for interior and exterior applications, and engine compartments, but also of nonferrous metals for cable harnesses and lithium-ion batteries: Food is better protected by good packaging and kept fresh longer which is more sustainable. Click here for laminating of nonwoven materials. The following factors have a negative impact on weldability: The following additives have a positive influence on weld work: These reinforcement materials predominantly improve the sound conductivity in semi-crystalline plastics. Ultrasonic welding of two parts made from the same plastic material will usually obtain the best result. Herrmann Ultrasonics, E-module: promotes sound conduction and determines coupling, Melting point: determines the heat requirement, Viscosity of the melt: high viscous melts can be kept within the joining area more easily, the process sequence is more uniform, Ultrasonic components for special-type welding machines, Robust and reliable in continuous operation. Industry-specific ultrasonic solutions, Herrmann products and profound expertise of ultrasonic technology – all brochures and publications. 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. Some people understand that any material can be welded. The map shows you how to reach us quickly. News from the company, press releases, images, and logos - compiled for you. 2021 Find here the answers to most frequently asked questions. The following drawings illustrate the basic principle of ultrasonic welding. Ultrasonic welding of plastics is used widely in making electronics, medical devices and car parts. In ultrasonic plastic welding, a vibratory motion at the horn face (amplitude) is transferred to the part. Unmatched Support. ABS, Acrylic, Polycarbonate and PVC are amorphous polymers - with little or no crystalline structure, they are ideal for ultrasonic welding. The Ultrasonic Plastic Welding Machine market research report delivers a thorough analysis of this business sphere with expert insights on the past and present growth matrix. UW is commonly used for plastics and especially for joining dissimilar materials. Phone: (714) 630-9530. 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. Titanium is the preferred choice of material for making ultrasonic horns because of its good fatigue strength, excellent acoustic properties, and good surface hardness.
