Southco’s Product Information Blog. Check it out!

Admittedly, I don’t follow a lot of blogs myself.  Honestly, I have little patience for people (even companies) who get off track, lose their focus, and try to become entertaining rather than informative.  That’s why I like this one.  Written by Daniel McCourt of Southco,  this blog features specific products, and provides good, practical information that designers and engineers can actually use.    Great job, Dan!  We’ll be following you closely!

 

Here’s one of his recent articles.  Enjoy!

Incorporate hinges early to save money and frustration

Tuesday, July 12, 2011 by Daniel McCourt

Part 1 in a 10-part series on specifying hinges
External HingesIt is not uncommon to wait until the last minute to incorporate hinges into a design. We know that not everyone has hinges at the top of their list of important things to think of when working on a new car, enclosure, or life-saving medical device.. However, considering hinges late in the design cycle can limit your options. You might have to compromise your design or force nonstandard parts into your product risking increased cost and reduced performance.
Over the next 10 weeks, we will examine multiple factors to consider when specifying hinges. Keep these tips in mind, and you’ll keep your options open (and your project costs down).


Yes, I'm this strong.  See how I hold on the steering wheel and avoid falling into the back seat?

Let’s start with one of the first considerations when it comes to hinges: strength.
How much load will the hinges bear? And many times it’s not just the weight of a door but all external sources of load. Will equipment be mounted on the door? Make sure to account for dynamic loading.
Another tip to keep in mind: the as the ratio of door width to height increases, so too do the stresses. For maximum strength, place hinges as far apart as possible on the longest edge of the door. Or, depending on the design, use a closer hinge spacing to stiffen the door or ensure sealing against a gasket.
Next week: How strong a hinge is needed? I’ll share four specific factors (and a handy formula) to help you out.
