Ultra-Short Pulse Lasers Are Great Tools for Processing Plastics for Medical Devices

Posted by Geoff Shannon on Tue, Feb 27, 2018 @ 12:35 PM

In the past few years, we have found that ultra-short pulse (USP) lasers are being used more and more for medical device manufacturing – from stents and catheters, to wire stripping and balloon texturing. The level of quality and dimensional accuracy needed fits well with the USP lasers, which do a great job of drilling, cutting, skiving, texturing and machining both plastic and metal-plastic combinations.

Looking for ways to improve your assembly process? - Try 6S

Posted by Michael Vest on Tue, Feb 20, 2018 @ 12:35 PM

I would say that most, if not all, manufacturers are continuously looking for ways to reduce waste and improve efficiency. If that describes you, I have a suggestion – adopt the 6S workplace organization method.

Projection Welding of Fasteners to Hot Boron Stamped Components

Posted by Bob Kollins on Fri, Sep 22, 2017 @ 09:00 AM

Projection welding of fasteners to hot boron stamped components

Automotive component assemblies often incorporate projection welding of fasteners. And more and more manufacturers are using hot stamped boron steel, like Usibor®, resulting in lighter weight components with increased tensile strength (up to 1500 megapascals (MPa). This helps them meet regulatory requirements while maintaining 5-star safety ratings.

Exposing high school students to engineering career paths

Posted by Mark Boyle on Thu, Aug 03, 2017 @ 08:46 AM

AMADA MIYACHI AMERICA strongly believes in serving the community and especially looks for ways to engage with students to encourage and develop the next generation of engineers. We have an active, thriving partnership with our local colleges and universities and provide technical internships to students in the engineering disciplines.

One fun event we recently hosted was a tour of the Monrovia, California facility by high school students from the San Gabriel Valley Economic Partnership. The partnership includes an education and workforce development initiative focused on a regional consortium of the Duarte, Azusa, Charter Oaks, and Monrovia school districts.

Spot welding: improve quality and reduce cost with inverters

Posted by Mark Boyle on Thu, Jun 29, 2017 @ 12:45 PM

Successful manufacturers constantly look for ways to improve quality while reducing costs. That’s why many are looking beyond conventional spot welding technology for something to help them achieve their cost reduction goals. Resistance welding traditionally utilizes alternating current (AC); however, this technology has limitations in the control of the output energy. Resistance welding with direct current (DC) using inverter technology, however, dramatically improves weld process control through closed loop feedback. This provides a consistent output, in turn lowering scrap and increasing production yield.

Ultrafast laser systems offer great promise as a manufacturing tool

Posted by Geoff Shannon on Tue, Jun 27, 2017 @ 12:30 PM

Owing to their very short pulse durations - sometimes less than the target material's conduction time - and very high peak powers, ultrafast (femtosecond and picosecond) laser systems offer unique material processing possibilities such as “cold machining” of parts with no/negligible heat affected zone. In fact, this short pulse width/high peak power, combination enables processing capability of almost any material, including metal, plastics, ceramics or glass.

Nanosecond laser micro welding: the possibilities!

Posted by Geoff Shannon on Tue, May 23, 2017 @ 12:30 PM

The nanosecond fiber laser is the most recent addition to AMADA MIYACHI's broad portfolio of micro welding solutions. Its output parameters are a bit different than other laser welding sources like pulsed Nd:YAG ,quasi-continuous-wave (QCW) fiber and the CW fiber laser. As the name suggests, the nanosecond fiber laser’s pulse widths are in the nanosecond range - under 250 nanoseconds (ns) - with pulse energies around 1 millijoule (mJ).

Connecting with HS robotics team to support next gen engineers

Posted by Mark Boyle on Tue, May 09, 2017 @ 12:30 PM

Recently we heard from “Suit Bot Sammy” (aka Samantha Childers), a junior at Monrovia High School (Monrovia, California), thanking us for helping the Monrovia Robotics program with the FIRST Tech Challenge. This is a cool program in which teams of 10+ members in grades 7-12 are challenged to design, build, program, and operate robots to compete in a head-to-head challenge in an alliance format. FIRST Tech Challenge encourages student teams to meet with members of the scientific community, serve the community, and fundraise to meet their goals.

The winning formula – helping next generation engineers race to success

Posted by Mark Boyle on Thu, May 04, 2017 @ 12:30 PM

Recently we had a great opportunity to help the next generation of engineers compete in Formula SAE® Electric, a collegiate competition to conceive, design, fabricate, develop, and compete with small, formula style electric vehicles. The event is sponsored by the Society of Automotive Engineers (SAE). Our foray into the fast-paced world began when a team from the University of Pennsylvania contacted us after seeing online papers we published on battery tab welding. The team has nearly 100 college students designing and building an electric vehicle, and was working on improvements to their car for next year’s competition.

Application labs - invest time up front to ensure success

Posted by Mark Boyle on Tue, May 02, 2017 @ 12:30 PM

Application engineers are a funny breed. They get their kicks from solving real-life manufacturing challenges – and the thornier the better! They like to get up close and personal with an application and help those having trouble to find the right way to weld, mark, cut, bond or machine a part. They also get a great deal of satisfaction from fixing a process that is taking too much time and affecting output (and the bottom line), one that results in unnecessary scrap or one that is out of limits. If the solution doesn’t work out the first time, they stick with it until they develop a one that works.
