3D printing tools for production use

Any production facility involved in stage tooling knows the cost in custom designed and manufactured tools. Tools that are used in assembly processes, quality control, material handling and many other operations can be very expensive to make. If the tools are used in short production runs , these costs factor quite a bit into the final price of the product. Ask any engineer how much a 1 off machined or CNC’d tool costs. Costs involved are design, analysis and machine setup.We have found 3D printing lends an enormous hand in keeping these costs low. Even if the tool is under a high stress process it’s very easy to print another one.  This wasn’t always the case, current engineering printing filaments that can take high loads are very popular now and inexpensive. The cost and time saving benefits are pretty large. We currently use 3D printed testing tools and have saved thousands. Contact us if you want to discuss cost saving techniques for your production area. http://www.mmtech.us

Rotary viscous dampers and production lines

Among the unusual applications I have seen over the years, one in particular sticks in my mind because it is extremely practical in keeping production line productivity high.  A client had a production line that was used in a critical painting operation. The line had to run smoothly yet be safe and also not be self destructive.  If the chain driven line had too abrupt of a jam these pendulum microswitch toggles would release the switch. They were very sensitive so EVERY time there was slight jarring the switch would flip and stop the line. What a production nightmare! Now the jarring was not bad enough to cause a paint defect but the stopping of the line would cause a defect by leaving a part in the paint spray path too long or too short depending on the cause. So we used a rotary viscous damper on the microswitch actuator. The damper was tuned to let slight jarring  not interrupt the safety switch. Only at a certain amplitude would activate the actuator enough to stop the line. This prevented the line from stopping for every little bump in the road. I never saw this type of application for a damper but here it was! You never stop learning. Bring your production line issues to us at http://www.mmtech.us. We may have a solution for you.

3D printing in Engineering


I have been doing a lot of new products and 3D printing has played a large role in moving things along.  The big change that has occurred was the huge advance in filament technologies.  More resilient and robust filaments have been helping smaller companies achieve fantastic results.  #taulman3d have produced high quality filaments worth trying.  See us at www. Mmtech.us and we can try to help in any way possible.

3d Printing and Manufacturing

https://photos.app.goo.gl/FREMz0RiID80Z15z1

Sometimes tooling for manufacturing is needed and a 3d printed part holder fits the bill. It saves time and money. In the video I am printing a tool piece for holding our product while assembly operations are performed. We can pass cost savings along to the customer. #manufacturing #mechanicalengineering #3dprinting

Food Processing Application


I have had a few conversations with customers regarding the application of slow close hinges in the food processing industry. It seems that to improve safety and processing abilities on the production floor a slow close hinge would be a great asset. Lids for equipment are quite large and unruly to handle when internal work needs to be performed. Also, there is a cleanliness requirement which needs a hinge that can withstand wash down and corrosive chemical exposure. At mechanical motion technologies we have always offered rotary viscous dampers and friction hinges which can survive exposure to these hazardous environments. Lids for equipment, refrigerator doors are just a few applications. contact us at http://www.mmtech.us for your custom application.

Dampers for Aerospace

We find that aerospace applications are the largest users of rotary viscous dampers and friction hinges. Overall our core focus is creating the most damping per unit volume that is possible. Precision damping in a slimline package is our expertise and we have proprietary processes to achieve these goals.  The same applies for friction hinges, we have new developments to achieve highe torque in smaller diameters than any other friction hinge manufacturer. We stand by that statement proudly. Please visit us at http://www.mmtech.us or call at 203-406-7900

Rotary Viscous Dampers and Cymbals

IMAG0187

I sometimes get inspired in different situations  for applications for my rotary viscous dampers. I was thinking of a rock concert where I was watching the drummer intently and noticed his technique for hitting and damping the sound of the long decay on large thin cymbals. He would hit the cymbal in the course of a song or solo and them use his hand to damping the decay of the sound waves to give a quick muffled decay.  I noticed the same drummer a few years later (Neil Peart of Rush)  using very small cymbals that would “splash” and decay very quickly.  Well that got me thinking that we could achieve a new kind of quick decay by using a rotary damper in a spherical configuration to slow the decay in a unique way  unlike anyone drumming now. I guess I have a little experimenting to do on my Ludwig drumset pictured above.  I knew I could get a musical idea once in my life! please come see our web site and contact us if there is any application you need to consult us for, it could be music to our ears.  http://www.mmtech.us

Rotary Viscous Dampers Made in The USA

imag0160

Made in the USA. We have all heard it and here at Mechanical Motion Technologies LLC we live it.  Having our production parts and prototypes molded, machined and assembled in the US gives us many advantages, quick access to vendors to forge a good working relationship and expedited, high quality parts.  This is extremely important.  I have compared the cost and quality between offshore and homegrown parts and we win on all accounts.  Which means our customers also win. We can get to production quicker and the product can get into the customers hands faster. The cost savings is worth it.  We have all of our parts engineered and manufactured in the USA. Give us a call or go to our website at http://www.mmtech.us

Aerospace Applications-Rotary Viscous Dampers

img_1017

Aerospace applications dominate our product line because our dampers and friction hinges are passive devices that need no maintenance and are very light in weight and slimline. The airplane manufacturers enjoy the fact that our dampers do not vibrate during turbulence, maneuvers, take off or landing. Silence is a major concern during these operations. We can customize our rotary viscous dampers to many difference sizes and configurations.So if  you need assistance in your aerospace application please contact us.

Rotary viscous dampers and their proper application

When looking over the requirements of a new project designers must balance the price of the product and features that are implemented.  Rigorous requirements sometimes yield higher cost materials. Environmental concerns will also guide the feasibility of using a viscous damper. Physics usually gets in the way of pipe dream  features and practical use. For the most part rotary viscous dampers add value and a high quality feel to a product.  But, is it in the budget? You must decide whether you are a high end product manufacturer or not.  What is your niche? Who are you appealing to? Consider these things before product realization occurs.  Contact us at www. Mmtech.us for a consultation.
