In situations where noise level exceed OSHA limits, the problem can be remedied by installing an enclosure and/or by using personal hearing protection HK KEEPLEADER is made-to-order manufacturer, the engineers can work with customer to produce the best version of an ultrasonic machine or customer tooling for required specifications, ultrasonic welding machine only can disturb very sensitive computerized device installed nearby, but very rarely, it may be necessary to suppress EMI emissions HK KEEPLEADER encourages customers to send in parts for the material, by which to provide welding samples and recommend the best unit in need, actually speaking, ultrasonic welding machine has many sides of factors in need of consideration in advance, for example, the wall thickness of welding parts, ultrasonic welding line, the design of welding line, the welding material Ultrasonic plastic welding machine (ultrasonic welder), weldable thermoplastic resins can be categorized as amorphous or crystalline, weldable amorphous resins include: Polycarbonate, Polyphenylene oxide, polystyrene, ABS, polyetherimide, acrylic, and polysulfone. Weldable CRYSTALLINE materials include: thermoplastic polyester, nylon, acetal, polyethylene, polyphenylene sulfide, and polypropylene. There are limited number of dissimilar, amorphous thermoplastics can be welded together (e.g., ABS and polycarbonate). Melt temperature difference for dissimilar materials can’t be greater than 50° F. Flame retardants can affect the weld by reducing the strength of the bond. In such cases, “overwelding” can sometimes be the solution. This involves utilizing a higher amplitude machine or a slightly longer weld time to create a sufficiently strong bond. An acceptable amount of glass contact for ultrasonic welding is necessary of plastics, Up to 20% is preferred. However, adequate welds can sometimes be achieved with up to 30% glass filler. Ultrasonic welding machine usually need ultrasonic welding line, so-called “energy director” approach in used for many joints, this requires a triangular projection be used on one of the pieces being joined and placed where the melting initiates, for leakt-tight joints and some semi-crystalline parts, a share joint is recommended, a shear joint requires some interference between the parts to be welded. As the parts are ultrasonically heated and compressed, one part “shears” softened plastic from the other. Ultrasonic welding machine (ultrasonic lace sewing machine) also can seal and cut nonwoven/textiles, material may be 100% synthetic or blends with up to 40% natural fibers. Acrylics, acetates, polyester, nylon, polypropylene, spandex and PVC are all suitable for bonding or cutting. In general, the higher the synthetic content, the easier it is to cut and seal with ultrasonic energy. Nonwovens including felted filter media are especially suited for ultrasonic bonding, many dissimilar materials can be bonded together. Melt temperature difference for dissimilar materials can’t be greater than 50° F. Ultrasonic welding machine has rotary/continuous ultrasonic bonding and stationary/traversing methods, the rotary method works like a sewing machine and produces a continuous seam or pattern, the friction between fabric, pattern roller and ultrasonic horn is greatly reduced if both sides rotate instead of having the roller rotate on a stationary horn, HK KEEPLEADER LTD also has portable ultrasonic spot welder, which can do spot welding, the welding size is 1mm up 15mm, the ultrasonic power is 150w up 800w Stationary ultrasonic welding machine has 15 khz and 20khz, the ultrasonic power is 1000w up 4200w, has split type, table top type and cabinet type Ultrasonic plastic welding machine (ultrasonic welder), please remember renowned brand “keepleader”
