Select the right laser source to produce passivation-resistant marks

Posted by Geoff Shannon on Wed, Mar 30, 2016 @ 12:30 PM

Fading or disappearing laser marks on medical devices?  You're not alone. It's a daily battle for many contract manufacturers and end users, and it’s a topic I am often asked about. People especially want to know what they can do to make passivation resistant marks on their medical device parts and surgical tools in order to meet unique device identification (UDI) requirements.

Are you on track for meeting UDI requirements?

Posted by Geoff Shannon on Tue, Mar 22, 2016 @ 12:30 PM

By now, most of you are at least vaguely familiar with the landmark law that gradually phases in the requirement for manufacturers of medical devices to place unique device identification (UDI) marks on all of their parts. Are you on track for meeting the deadlines for the direct marks that are required?

Stent and tube cutting technology for next generation production needs

Posted by Geoff Shannon on Tue, Mar 15, 2016 @ 12:30 PM

The stent and tube cutting technology coming on the market today is miles ahead of what we’ve been working with for years – and that’s music to the ears of many, especially in the medical device industry. Stent and hypo tube cutting has been around for some time, but as demand continues to grow for these types of devices, cut quality and production rates are more important than ever to meet the demand and make the necessary return on investment.

Laser marking: use laser markers to mark your parts and verify your process

Posted by Mark Boyle on Tue, Feb 09, 2016 @ 12:30 PM

Production floors can be hectic places with high demands and a need for 100 percent accuracy. One common way of systemizing process flow is to use production routers or travelers with barcodes. This technique ensures that the proper steps are followed to produce the part. It can also be used to insert quality checks at key points and to identify bottlenecks.

Laser welding modes: conduction, transition, & keyhole welding

Posted by Geoff Shannon on Tue, Jan 19, 2016 @ 12:30 PM

The laser is a high energy density process that provides a unique welding capability – maximum penetration with minimal heat input. There are three basic weld modes, which correspond to the level of peak power density contained within the focus spot size: conduction mode, transition keyhole mode, and penetration or keyhole mode. Figure 1 is a graphic illustration of the three weld modes.

Battery welding: using lasers for tab welding applications

Posted by Geoff Shannon on Wed, Nov 18, 2015 @ 12:30 PM

We’ve covered a variety of battery welding related topics in this blog space - not surprising, given the importance of batteries in today’s world. This post, however, will narrow the discussion down to laser welding the tabs to the terminals for a battery pack.

Avoid these pitfalls when moving to a laser welding process

Posted by Geoff Shannon on Thu, Oct 08, 2015 @ 12:30 PM

We often get customers asking us about moving an existing welding procoess to laser welding so they can take advantage of the laser’s great benefits.  I'd like to take a minute to review a few of the potential pitfalls of moving to laser welding, so you might avoid them and make YOUR transition as smooth as possible.

Plastic welding with lasers - making it work for you

Posted by Geoff Shannon on Tue, Oct 06, 2015 @ 12:30 PM

Lasers are effective tools for plastic welding, even for clear plastics.  The key to success is material selection: it must be a thermoplastic, meaning that it becomes soft or plastic when heated, hardens on cooling, and that process may be repeated.

Inside the laser solutions for e-cigarette manufacturing 

Posted by Mark Boyle on Tue, Sep 08, 2015 @ 12:30 PM

The e-cigarette industry is evolving rapidly. When e-cigs first came on the market, production rates and volumes were low – the earliest e-cig manufacturing lines had a production goal of about 30-50 e-cigs per minute. As demand for e-cigs has increased, manufacturers have been pushing production volumes dramatically – production goals of 300 or more e-cigs per minute are now being required. As production rates increase, new technologies are needed to support a robust manufacturing process that can keep up with the growing volumes while maximizing yield and reducing scrap.
