Make it Better and Improve Performance!

Dymax Corporation, located in Torrington, CT, is a leading manufacturer of advanced light-curable adhesives, coatings, oligomers, light-curing equipment, and fluid dispensing systems that work together to optimize manufacturing assembly processes.  Dymax came to Sigma Design Company to improve their WIDECURE® conveyor system. WIDECURE is a 25″ wide UV curing system with 700 mW/cm² of curing power. This system is typically used in industrial plants for the curing of adhesives during the assembly of aerospace, electronic and automotive components.  Dymax Corporation is well known for making manufactures more efficient and need to update the design of the WIDECURE with additional safety and performance features. Dymax presented Sigma with a solid and dependable machine, but a machine that lacked the features needed by its industrial customers and users. Learn more about Dymax here.

Sigma took their original prototypes and examined every single nut and bolt to do a complete redesign of the original machine. Aside from adding a number of safety and performance features to the system, Sigma greatly improved the user interface of the unit and overall quality and reliability of the system. The WIDECURE is aesthetically more pleasing and a truly gorgeous machine. Operators will be very pleased with its new ergonomic design and low level machine noise. Sigma’s new design also includes provisions for lifting and transporting the machine in a safer manner. WATCH VIDEO HERE!

Prototypes with a Twist

An inventor needed a customized auger for an unusual application. The problem was that it could not be produced using traditional  CNC machine methods or as an injection molded plastic part. So, a few hours spent with a product development expert at Sigma resulted in the complex blade geometry needed for the auger in a process that could be readily manufactured.

 With our Rapid Prototyping FDM machines we can take your design concepts and grow ABS plastic parts. Used as a quick, proof of concept development tool, parts can usually be created, manufactured and shipped in just two (2) days.

Sigma Design is ready to:
*Take your geometry and produce prototypes.
*Design new geometry and produce prototypes.
*Develop and manufacture prototype devices, specialty production equipment and controls with testing capabilities in-house.

Hydraulic Power Test System Development for the United States Navy

Ken DeGraw, Sigma Design Company’s northern NJ rep recently brought in a very interesting project. We are working on a NAVSEA research program to design and build a large Hydraulic Power supply for the US Navy’s weapon testing system.CIMG3348

Sigma is very excited to work on a project with the US Navy. Talk about a project in ‘our wheelhouse’ as they say. Jerry Lynch, a ‘tin can sailor’ who served as a destroyer GMG2 gunner was thrilled to have the opportunity to work on this special project supporting shipboard defense systems for Navy operations.
Michael Collins, the lead engineer on the NAVSEA project worked for the US Navy in Philadelphia before coming to Sigma. This project requires the creative design of safety features while providing 50% more power through their
Hydraulic Power Supply system. With operating pressures in excess of 3000psi the pressure compensation and hydraulic shock suppression systems were key features in the new design. This system joins the growing roster of Sigma’s manufactured in NJ products- designed and built in NJ. Sigma is proud to have the opportunity to work with the Navy to improve operational shipboard defense systems used around the globe but made in NJ.

Winning the Rat Race

The term ‘rat race’ has been described as a “seemingly pointless or endless pursuit”.   The work of today’s research scientist is hardly pointless but one aspect of the work, while not endless, was a tedious pursuit.  We are describing the work of researchers charged with the task of  observing and documenting the behavior of mice in lab settings. The job was to watch and score lengthy video recordings of the creature’s every move.  That was until Jessie Brodkin came up with an idea that he has described as “thinking inside the box”.  

Brodkin’s creation is The Behavioral Spectrometer (http://behavioralinstruments.com), a humane device that captures everything your mouse does without having to watch and score hours of video recordings.  Brodkin found SigmaDesign Company and its team of mechanical design engineers for the job.  Sigma designed, tested and now manufactures this ‘mouse house’, The Behavioral Spectrometer, right here in NJ.  The job required advanced engineering analysis and skills to incorporate LED lighting, vibrations sensors, and isolation dampers. It has the capability of using advanced video and vibration analysis to record the most detailed description of mouse behavior ever.      

Brodkin’s ‘made in NJ’ product has met with huge success in the research and pharmaceutical world. The Behavioral Spectrometer is used by Rutgers University’s Department of Neuroscience and Cell Biology, Pfizer, and other global R&D laboratories for the development of new treatments and drugs. The latest 4 systems were just shipped to a R&D laboratory in Austria. To read customer articles and references: http://behavioralinstruments.com/references

This is another success story showing Sigma Design Company’s ability to provide manufacturing engineering and product development services to people like you.Sigma Design is your single source engineering and manufacturing resource for new products and specialty machinery.

SIGMA Helps Redesign Surgical Supplies Stand for USA Market Relaunch

SIGMA is capable of improving the functionality of various industrial, consumer and healthcare products for relaunch into the marketplace. One example is the surgical supplies stand, which was recently introduced from Europe to the US surgical market by our customer.

The global fortune 500 medical supply company identified a ‘bell weather’ product used for over 30 years in Belgium and German. This seemingly utilitarian supply cabinet plays a crucial role in hospital surgery rooms for efficient organization and on-demand availability of critical surgical supplies.

Surgical Supplies Stand, a SIGMA Redesign for US Market

Surgical Supplies Stand, a SIGMA Redesign for US Market

In order to introduce this product into the US market the customer needed to adapt its design to accommodate the different sizes of surgical supplies in the US. So the surgical cabinet drawings needed to be reworked from the metric system to the US Unit system (based on inches) for manufacturing in the US. One challenge was to produce CAD manufacturing drawings in US standards (inches) from old hand drawings (metric).

SIGMA helped in this product relaunch for the US by creating a more futuristic look, improving certain features, suggesting design improvements and recommending materials. New functionality was added to allow for carrying, pushing, spinning or connecting the surgical supplies cabinet to the wall of an operating room.

The updated product was successfully released by the customer in the US surgical market with new functionality for better productivity for surgeons and their teams.
