“I need clean plastic parts!”
We hear this from our customers all the time. We can help. Extol now offers a cleaner way to weld plastic parts together.
Plastic welding can generate dust and debris, especially when using friction methods like ultrasonic or vibration. The problem gets even worse when the parts are glass filled. But demand for cleaner systems continues to increase, particularly in the medical and consumer markets. Even automotive systems are tightening cleanliness specifications, and insisting on cleaner parts. Materials like nylon and polycarbonate are typically joined with friction methods, but they often need a cleaner process. Extol’s laser plastic welding systems can be the answer.
Extol is pleased to announce that we have received a patent for our revolutionary nanoSTAKE plastic staking technology. This is Extol’s second patent for a staking technology that will change the manufacturing industry. NanoSTAKE was developed to tackle the challenge of staking small plastic bosses in tight, hard-to-fit locations while being safe to use on electronics and other sensitive applications. The closed-loop process is fast and easy to use thanks to the proprietary Smart Respond™ heating system that rapidly heats and cools the punch at the tip of the module.
Humans have been fascinated by reflections for millennia. Narcissus was bewitched by his reflection in a pool of water and mirrors have magic powers in fairy tales. Speaking of mirrors, they are simply smooth surfaces with shiny, dark backgrounds that reflect very well. In addition to glass mirrors, polished and sometimes coated metal also reflects light very well. Using mirrors in laser plastic welding is an innovative way to direct the light waves to weld ribs that might be otherwise impossible to reach without either moving the part or the laser source.
Powder-based 3D printed polypropylene (PP) parts are now available at Extol. The addition of PP expands Extol’s 3D printed powder-based materials, which already include PA12 and TPU.
We’ve received feedback that our powder-based 3D printed PP parts are performing with the toughness, ductility, and chemical resistance that customers expect from molded PP.
Laser plastic welding is a proven, powerful, and effective way to join plastics. It’s been used in industry for over 20 years and its ability to weld a wide variety of part sizes, with precision weld joints, minimal flash, and no particulate is unmatched by other welding processes.
Extol now has the capability of 3D printing components out of TPU material using HP’s Multi Jet Fusion process. The ability to print strong, homogeneous structures in TPU is a game-changer over other printing technologies. Extol’s Digital Development Center now can print parts out of both PA12 and TPU.
