Miyachi Unitek's Call to Action: Serving Your Communities

Posted by Barbara Kuntz on Thu, Dec 06, 2012 @ 08:00 AM

It’s that time of year – the holiday season – and I’m certain that at least some of your friends have taken to the social media networks to post about the many things they’re thankful for. And even if you don’t participate in the public thankfulness, you can’t help but reflect on all the things that you, too, have to be thankful for. So in today’s post, I’d like to change directions just a bit to say that I am really thankful to work for Miyachi Unitek, which is so much more than just the place where I earn my paycheck. After working for the company for15 years, it is a second home, and its people are like family. More than 40 percent of our employees have been with us longer than 10 years – and 10% have been with the company more than 20 years – half of those, more than 30 years. 30 years! According to the Bureau of Labor Statistics, average tenure at a company in the manufacturing industry is just 6 years.  We must be doing something right!

Why do our employees stay so long? Because we are all made to understand that we are part of a whole, working toward one goal; no one job is more important than another…and, I believe it’s also because the company cares not only for its employees, but also for the industrial and geographic communities in which we work

Weighing the Pros & Cons of the Major Marking Methods

Posted by Mark Boyle on Wed, Nov 28, 2012 @ 11:44 AM

Not long ago, I discussed some of the factors you should consider when deciding which marking technology to use:  material type, part function, geometry, surface finish/roughness, coating, mark quality, mark dimension/part size, and serialization - all play a part in this process. Today’s post digs a bit deeper into selecting the right marking technology for your specific application by looking at a concise listing of the pros and cons of each of the major marking technologies: inkjet, dot peen, chemical etching, and laser marking.

AC, DC, CD or HF: Which Spot Welding Power Supply Should I Use?

Posted by Marty Mewborne on Tue, Nov 20, 2012 @ 08:00 AM

I recently posted a blog about closed loop welders and how you can get the most out of using them, and it occurred to me that some of you may not be familiar with the different resistance spot welding power supply technologies, how they work, and what they can be used for. So here is a short description of the four different types, including both closed loop and open loop designs.

Projection Welding: Balance Heat and Extend Electrode Life

Posted by Marty Mewborne on Wed, Nov 07, 2012 @ 08:00 AM

If you read my recent blog on heat balance, you know that there are five different techniques that can be used to balance weld heat that don’t  involve making changes to materials or part design.  And at the end of the blog I mentioned that if you’re still having difficulty after trying all five of the techniques, you may want to consider adding projections to one of the parts.

Direct Part Marking: Enabling Cradle-to-Grave Traceability

Posted by Mark Boyle on Tue, Oct 30, 2012 @ 08:00 AM

Product traceability over its complete lifecycle is one of the key issues driving marking technology today. Manufacturers are looking for cradle-to-grave traceability to improve product quality and make sure all their suppliers fall in line with quality standards. Oh, and let’s not forget they also want to make it easier and less costly to engage in product recalls.

Spot Welding Equipment Calibration: the Key to Reducing Down-Time

Posted by Marty Mewborne on Fri, Oct 26, 2012 @ 08:00 AM

Equipment calibration may not be the most exciting activity, but it can go a very long way in saving you both time and money by reducing plant down-time due to process control fluctuations.

Heat Balance: the Key to Successful Resistance Welding

Posted by Marty Mewborne on Tue, Oct 23, 2012 @ 08:00 AM

All right folks.  Let’s cut to the chase.  Successful resistance welding boils down to heat balance:  getting both parts up to their bonding temperature at the same time.  If too much heat goes into one part, and not enough into the other, the overheated part can become weak, and the weld won’t be strong.

Laser Tube Cutting: 5 Tips for Successful System Integration

Posted by Geoff Shannon on Thu, Oct 18, 2012 @ 08:00 AM

We’ve spent a lot of time this past year talking about our medical tube cutting capabilities, and, as you might guess, we’ve been getting a lot of calls on the subject. Let me start by saying that successful thin wall metal tube cutting is all about the results: excellent precision, superior edge quality, and tight dimensional tolerances - and so it makes sense that our customers and prospects are concerned about getting the “perfect” laser for the job.  Achieving these precision cuts, however, isn’t all about the laser – it’s more about its successful integration into a complete system.

What exactly does this integration entail?  Well, to start, in addition to the “perfect laser,” each application requires a workstation, focusing optics, assist gas, a motion package with programmable motion, full-featured control software with post processor capability and a user friendly and intuitive interface. Integrators need to develop an entire system in which all of these elements work together to achieve the necessary cut quality, production throughput and minimal downtime.

Closed-Loop Resistance Welding Control: WIFM?

Posted by Marty Mewborne on Tue, Oct 16, 2012 @ 03:53 PM

What’s the fastest and easiest way to improve your manufacturing welding processes? That’s simple: use a closed-loop resistance welding power supply! And you’re thinking “okaaay…what’s ‘closed-loop’ and why do I want to use it? I know why you want to sell it – it’s a higher end power supply that costs more money, but exactly how will that help me in my process?” Well, I’m going to tell you.

What is closed loop? At a high level, closed-loop resistance welding power supplies use current and voltage feedback sensors to precisely control the energy delivered to the parts. This ability to accurately control weld energy is a key factor in overcoming problems associated with process variation and the rapid changes in resistance that happen during the weld.
