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!

Sigma engineered several important features, making the new WIDECURE system a real state of the art unit. The control scheme of the machine was redesigned to be category 3 safety compliant.  Our engineers added an Allen Bradley PLC and HMI (Programmable Logic Controller and Human Machine Interface), and an open loop stepper system to smoothly lift and lower the UV lamp assembly.  Sigma turned a dependable machine into a world class system allowing the customer to better meet the needs of the industrial marketplace.

Full “STEAM” Ahead

We are all familiar with STEM but what is STEAM?  “STEAM” takes the standard STEM formulation (science, technology, engineering, and math) and adds an A for arts. The movement, led by Rhode Island School of Design (RISD) encourages the integration of Art + Design in K-20 education.

It is not about teaching art as a separate discipline but exploring where art naturally fits. Proponents of STEAM suggest we can be better engineers by learning how to think creatively through challenging design projects, like this one.   

Our design team at SIGMA became part of a RISD graduate’s studio in a recent fabrication project combining art and engineering. Rebecca Manson, an artist specializing in ceramics, was creating an eight foot diameter sphere made of thousands of small porcelain parts. Ms. Manson describes the piece as…”a look underneath our skin at the enduring structure that all humans share”. By recalling what is known as the ‘Overview Effect’;.. “the principal that when one sees the earth from space, feelings of deep love and concern for the planet reportedly wash over them…” the sphere represents a memorial to the planet earth. This stunning ‘union of bones’ created with paint over glaze over pigmented clay results in layers of color that change with light, angle and personal perspective. Only a very talented engineering and fabrication team would be able to make this project a reality.

Fortunately, the artist found SIGMA Design.

The giant, extremely fragile sphere had to be constructed in a mold, one half at a time.  SIGMA’s challenge was to construct the internal structural framework, which would support and align the sphere to rotate about its vertical axis.  Solid knowledge of geometry, strength of materials, and adhesives was required. Testing was done on the materials and their flexibility under various conditions and temperatures. Too much rigidity in the structure or adhesives would have caused the structure to break.

Sigma Design’s Max Burns and Bruce Knapp working on the 1/2 sphere

When the first half was delivered in its ‘nest’ a rope ladder was constructed to allow work on the internal structure without stepping on the delicate ceramic shell. When the internal structure was done and secured into the shell, it was time to release the shell from the ‘nest’.

If you have ever tried to turn a warm cake out of a pan, hoping it would come out in one piece without breaking, you might understand our anxiety as we carefully turned over the nest. Would this giant sculpture come crashing out destroying months of work on the ceramic pieces? Would it require a bit of coaxing, tapping, and gravity, like that cake? 

We held our breaths, turned it over, and, well- it was stuck! Twelve hours later we had the sculpture safely out of the nested mold, which then returned to the artist’s studio for the creation of the second half.

Rebecca’s team got to work and weeks later we had the second half back in our shop. Upon delivery of the ‘northern hemisphere’, SIGMA got to work on joining the halves, and installing the pedestal.

The finished product! (Sphere #2, 2016)

Throughout the project, SIGMA’s ability to support the artist’s vision while working within the realities of math and physics was a unique challenge. The idea that STEAM education might make these types of collaborations happen more often is very exciting to us.

Interested in Contributing to US Manufacturing?

More than 100 years after the first Labor Day celebration, there is still a debate over who first proposed a day to celebrate the American worker. Was it the carpenter from New York or the machinist from New Jersey? The New Yorker suggested a day to honor those “who from rude nature have delved and carved all the grandeur we behold.” (Link here) Despite the eloquence of the carpenter, this NJ company votes for the machinist. Either way, both sought to recognize the American worker and the dignity of labor.

As we celebrate Labor Day 2016, we can’t ignore its partner every September—‘Back to School’.   And we wonder, who will teach the next generation of manufacturers? Tech schools and community colleges are partnering with local manufacturers like Sigma Design Company to give the next generation of workers the technical education and chance to start a manufacturing career in NJ. We recognize that seasoned machinists and other manufacturing tradesmen are also an integral part in this education process.

For senior workers, there might be a desire to slow down but not stop working altogether. Studs Terkel, the author of “Working”, writes “Work is about a search for daily meaning as well as daily bread, for recognition as well as cash…….” We think working with inventers and designers, and manufacturing right here in NJ can provide immeasurable satisfaction—and some cash.

We do honest work that leads to the creation of tangible products. As most of our work is custom and requires a multitude of talents, we’ve found that there is nothing that a group of skilled workers cannot figure out! It is that complement of training, age, and experience that makes our projects successful. We are offering experienced tradesmen an opportunity to teach their craft to the next generation of American manufacturers.

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.
