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.
Extol has launched a new Digital Development Center (DDC) to provide parts and engineering support to help its customers develop high-value applications for additive manufacturing using HP Multi Jet Fusion technology.
Design engineers often ask us, “How strong will my staked joint be?” Usually, they’re designing a plastic assembly that needs to be staked, and they need to know how to design the part so that it will be strong enough for their application. They just want a number, like 450 N. If they know how strong one stake point will be, they can plan how many stake points they need and where to locate them. The good news is that we can estimate the answer…
So, you’ve seen the new revolutionary nanoSTAKE technology and you are wondering how you can get it on your next plastic staking application. There are two great ways to do that. You can purchase a turnkey nanoSTAKE machine directly from Extol, or you can purchase nanoSTAKE through your preferred integrator. Either way, you get expert technology service from our knowledgeable team. Let’s talk more about what is included in a nanoSTAKE integration package and how they work.
If you do any hot-plate welding, you should start monitoring melt force to improve your weld consistency and quality. Extol’s Rapid Conductor hot-plate welder is equipped standard with three servo-driven platens: the upper and lower press platens, and the heated platen. Servo control eliminates the need for hard stops and ensures that all the pressure applied by the welder goes directly into the components being welded. It also allows the machine to control and monitor the forces throughout the process. Being able to measure the melt and seal forces means you can quickly detect and correct issues.
Extol has recently introduced a new lamp for the ISM20 InfraStake module. This lamp is 35 W, like its predecessor, but the output is enhanced to provide shorter heat times for a faster InfraStake process. Comparison testing of the new lamp showed a notable reduction in the heat time required to stake a variety of plastic materials and colors.
Spin welding is a pretty straightforward process. You spin one plastic component against another and the friction between them causes the material in the weld joint to melt. Even with a welding process this simple, it’s easy to make design mistakes that will cause headaches later. Here are three common mistakes that you should always avoid.
