Sigma Design Builds Lubricant Testing Machine for a Global Petroleum Corporation

Testing and validating product is of paramount importance no matter what industry you are in, and this often requires specialized equipment and processes. When it comes to industrial lubricants, it is critical to ensure that these products will provide the advertised level of protection for the equipment to which they will be applied.
Viscosity is a key metric specifically for lubricants, which is defined as a measure of a fluid’s resistance to deformation at a given rate. In simple terms, viscosity is a fluid’s “thickness”.
This can get complicated when it comes to lubricants in high friction applications such as an automotive engine or a turbine spindle. As heat rises due to friction, a lubricant’s viscosity, and thus its wear protection, will decrease. Knowing how effective your grease will be at room temperature and in operation is critical for manufacturers and consumers alike.
Sigma Design recently developed a lubricant test machine for a global petroleum company, one of our valued customers, to measure changes in viscosity of grease over a several hour-long trial. This rotating equipment is loaded with large, greased bearings and spun at several hundred RPM. The equipment is designed to measure the resistance of the grease between a driven top-half and idler bottom-half of the bearing chamber. The resulting force is displayed on a simple and reliable analog gauge that can be viewed and logged throughout the test. Our equipment provides a simple solution to a crucial need.
Sigma Design has developed and built analytical, testing and validation equipment for dozens of our customers across a wide variety of industries. From consumer product testing to cellular research, Sigma Design has been a valued and trusted manufacturing partner of equipment for over 20 years.

Vertical Farming Industry Projected to Explode Globally

Recent agricultural advancements have become as innovative as they are necessary. Steady population growth in addition to climate factors have forced the farming industry to start to evolve. These two factors have led to conventional farming often becoming more unpredictable and expensive. Moreover, economic changes in the developed world will make providing an ever-growing food demand more challenging for the less developed world.

Vertical farming as it is known today was introduced as a concept in 1999 at Columbia University when a professor and his class proposed a design of a skyscraper that could feed tens of thousands of people. That exact design has yet to be built. However, it was a proof-of-concept exercise that started the mainstream conversation on vertical farming.

Since then, vertical farming around the world has gained traction and has generated commercial support along with technological advances. Now, this industry shift from conventional to vertical has become viewed as a necessity in our evolving world. Because of this, vertical farming has become an area of fast-growing interest and investment. A recent study projects a market size in the industry growing sixfold from 2018 through 2026.

The process of establishing a successful vertical farm operation takes a groundswell of effort from many parties – from property developers to architects, botanists, and mechanical system designers for nutrient distribution, automated harvesting, and packaging.

Sigma Design has expertise with the automated support systems that keep vertical farms producing crops, having worked with several companies on system development. Sigma has helped solve numerous challenges such as nutrient dosing system footprint and design. We have the ability to design and develop systems for vertical farming, along with the in-house manufacturing capabilities to build, test and deliver the systems we design. This makes Sigma an ideal choice to partner with in the accelerated pace that the vertical farming industry demands.

The Large Project Dilemma: Outsource vs. Onboard

Successful companies often find themselves at a crossroads when undertaking a large, new project. Whether increasing capacity, developing a new product or system, or modernizing existing equipment, an organization can find itself in a bind when trying to find bandwidth with internal engineering and manufacturing capabilities. A choice must be made that can alter the course of the project significantly before it even begins, find an outside manufacturing partner, or bring on additional resources. The right answer is rarely obvious.
Adding design engineering resources can be a double-edged sword. Generally, a younger engineer will be cheaper but could take weeks or months to get fully up to speed and may require supervision to start that could disrupt other employees. A more experienced engineer should get up to speed considerably quicker, however will be more expensive to employ and is not as readily available in the job market as a younger engineer would typically be. In either case, the cost of employment obviously goes far beyond salary once benefits, hardware and office costs, and payroll taxes are added. The total cost of employment to a company is often 2-3 times the actual salary paid to the employee.
Finding a design, development and manufacturing partner alleviates many of the issues of bringing on new staff for a project. For one, as soon as a project is kicked off, a proven firm such as Sigma Design can get immediately to work. The only costs paid are hours spent on the project, whether it be design and drafting, engineering analysis, or review by senior engineers. One of the biggest advantages however is the ability for an established design firm to work autonomously. All that is required from the customer is attendance and communication at periodic design reviews and update meetings to make sure the development is meeting expectations. When a program is designed with specific phases and deliverables you can simply “turn on” or turn off” the team expenses depending on your needs.
What happens when the design phase is done, or it is time to transition into the manufacturing phase? If the engineering was kept in house, is there enough incoming work to support the additional resources that were hired? Typically, where design programs require under 1000 workhours it is more cost effective to partner with an outsourced firm rather than hiring. Also, today when you cannot find the experienced candidates what choice do we have? Wait or postpone the program or move forward knowing the earlier you launch the more beneficial it is to your firm.
Additionally, are there adequate manufacturing resources in house to support the next phase of the design / build project. Or are there additional hires needed to be made to support this phase? With a design/build partner like Sigma Design, the same engineers that develop the design will be the same engineers overseeing its manufacture. The logistical efficiency of an engineer selecting vendors for commercial part of an assembly during design, ordering the parts for the build, and then overseeing the entire production process cannot be easily quantified for this comparison. However, the advantages of keeping a project in the same building, from design kickoff all the way through factory acceptance testing and shipping are massive. This typically makes the entire process much more economical than trying to tackle a large project on your own.
Is your company considering a large design build, and unsure if you have the resources in house to complete the project? Give Sigma Design a call today! Over 1000 completed projects to date. On time – On budget!

Sigma Design Reflects on 22 Years of Evolution

Sigma Design is celebrating their 22nd anniversary under current ownership. However, the company’s origins go back much further, originally founded in 1962 as a machine design firm by brothers Murph and John Abraham. Machine design became a tougher and tougher gig as the manufacturing sector in New Jersey, and nationwide for that matter, started to contract through the 80’s and 90’s. The Abraham brothers had started seriously considering closing shop. Sigma’s current owner, Jerry Lynch, knew the brothers for some time. As fate would have it over a friendly lunch, they mentioned that if the right buyer came along, they would probably sell the company. Entrepreneurship had been a lifelong dream for Jerry, an engineer by trade with decades of experience in manufacturing. The idea of taking a company that was established but struggling and in need of a new vision appealed to Jerry and the acquisition was complete in early 1999.

Sigma Design began under new ownership as it had ended under the former ownership, strictly a design firm with no manufacturing capabilities. Jerry could see the trends, as well as the desire by current customers to have a design firm that was also engaged in the manufacturing and production process. Customers wanted a one stop shop that could produce their designs, rather than just deliver the detailed design and manufacturing package. The ability for a single company to fully design and draft, then pilot, test, debug and refine a piece of equipment became strongly in demand. Many large manufacturers do not have the internal resources dedicated to refining and perfecting engineered systems. This ultimately led to the foundation of the Sigma Design of today, when in 2011 they purchased a 20,000 sq-ft facility to afford means to manufacture their designs.

Sigma continued their evolution once they had room to work. Since acquiring the new facility they have gained capabilities in all facets of manufacturing. Sigma has a full weld shop offering qualified welders in TIG, MIG and SMAW process as well as a CNC machining area. They have a fully tooled assembly area which can accommodate electrical control panel fabrication and large electro-mechanical assemblies. Drawing on an area of expertise of their owner, Sigma formed a partnership with Spiral Water Technologies. This necessitated a 200 GPM water filtration system test loop that is now a fixture in the Sigma Shop.

One area where Sigma Design excels is with advanced engineering and analysis. Sigma caught on early to the 3D modeling FEA trend and has engineering expertise to use these tools. Performing stress analysis, heat loading, fluid flow etc. in a digital environment helps their customers visualize their designs and adapt to design conditions before manufacture, and more importantly, service in the field. These tools also aid with material selection and manufacturing process layouts. Sigma has become an expert ally for their customers in using these tools on both Sigma Designs, as well as finding non-obvious challenges with customer supplied designs. Jerry along with his smart, creative staff has transformed the business into a single-source provider of design, analysis and manufacturing services of new products, equipment, and machinery.

As Sigma heads towards the future, they are gaining momentum and stronger than ever. They have started to establish themselves as a reliable design and manufacturing partner for large, international companies. This has led to an aggressively growing work history, especially with repeat manufacturing work of large devices and pieces of equipment. Sigma will continue to evolve, learn, and enhance their business model as their company grows into 2021 and beyond.

Lessons From 2020 Have American Manufacturing Ready for a Strong 2021

In what wound up being one of the most challenging years in anyone’s memory, the American economy faced a gauntlet of obstacles in 2020. A global pandemic, record unemployment numbers and a contentious election cycle led to a disastrous first half of the year by many metrics. However, as it always has, the American economy and manufacturing sector improvised and adapted. Remote working, meeting, and selling surged as the US had to respond to the pandemic, which also placed an even higher focus on employee safety. Efforts to reshore American manufacturing were already well underway heading into 2020, however the pandemic and seemingly instant surge in consumer demand for goods like PPE, medical goods and cleaning equipment led to rethinking many industry supply chains. Countries where labor is cheap often lack the infrastructure to quickly respond to large demand swings. The cost of commercial transportation continues to and will most likely always continue to rise. Reshoring became even more of an economical issue, as well as a necessity for increased response to demand.

From a recent Forbes.com article:
“Despite 60% of manufacturers feeling the impact of COVID on operations, a recent survey of senior leaders of manufacturing and distribution companies noted significant or modest growth in company revenue during the pandemic. Demand for products is surging, requiring new and innovative production methods, and many manufacturers have stepped up to the plate. As we close out the year, we will better understand just how much manufacturing changed in 2020. But economic uncertainty aside, the unprecedented supply chain disruptions of the year are a blessing in disguise for manufacturers, as they encouraged the often-stagnant industry to move faster and become more resilient than ever before. If there were a year to push the industry forward towards progress, this was it.” 1

American manufacturing looks to be heading into 2021 largely recovered from the hit it took in early 2020, and ready to soar. It is easy, and somewhat lazy to point to the DOW as any sort of indicator for the economy, specifically in manufacturing. However, the American Manufacturing Index (US ISM Manufacturing PMI) is a reliable indicator of the state of the manufacturing sector, and signs are looking great heading into 2021. The index is up roughly 45 percent from its low in May 2020, and almost back to its highs we experienced through 2017-2018. With the COVID vaccine already being distributed, albeit in limited numbers, America is on the cusp of turning the corner on the pandemic and getting back to some state of normalcy during 2021.

It is no secret that the domestic network of small design, engineering, and fabrication businesses are the backbone of large American manufacturers. At Sigma design, we pride ourselves on being part of that network serving large American companies across many industries. Whether it be Medical and Life Sciences, or Clean Energy and Wastewater Treatment, Production Machinery and Fixturing, or a startup getting its product design refined and to market, we have the capability to serve any customer at any level. Sigma Design also looks poised to be heading into 2021 with great momentum and an ever-growing portfolio of projects for our customers. We have invested heavily in our capabilities in recent years to be a one stop shop for our customers. From advanced design analysis and engineering, welding and fabricating, machining and assembling, to panel building and programming, Sigma Design can take a project from idea to reality. We have a library of satisfied, repeat customers to prove it.
