Mattress ASTM Testing Machines
Sigma designs two machines for SGS Govmark to evaluate mattresses to ASTM F1566-14 Specifications
The Durability Tester and the Cornell/Firmness tester are two standalone machines that were developed to test mattresses according to the procedures defined in the ASTM F1566-14 Specification.
The Durability Tester is used to test mattresses according to Section 7 of the specification and can test mattresses from twin size to queen size. The machine moves a 240 lb. roller back and forth across the mattress to simulate years of use. The roller is driven back and forth across the mattress via a servo driven belt system and once it starts it can run 100,000 cycle tests automatically without operator intervention or supervision. It features safety mat system to detect if any objects or person gets too close to the machine while operating and automatically stop all motion. The Cornell/Firmness Tester is used to test the mattresses according to Sections 6 & 9 of the specification.
The Cornell Tester uses a servo driven linear actuator with a two- lobe platen to continuously plunge into the mattress at 100 strokes per minute. A load cell mounted between the actuator and the platen is used to measure reactionary forces and determine how deep into the mattress to plunge. The machine then automatically stops at defined cycle counts and performs measurements on the reactionary forces of the mattress at set depths. Before and after a Durability Test or Cornell Test, a firmness test is run to determine the mattresses firmness in its “new & unused” state. The Firmness Test uses the same servo-driven linear actuator with a flat platen to plunge into the mattress at a rate of 10 inches per minute. The results during the test and changes between the before and after tests are then summarized in a table on the HMI as well as graphically for the operator and manufacturer to see the change in mattress properties over the duration of the test.

Test Stand for Face Masks
In response to an uptick in requests fueled by the COVID-19 pandemic, a testing laboratory asked Sigma Design Company to design and manufacture a Bacterial Filtration Efficiency (B.F.E) test stand to measure a face masks efficiency at removing virus particulates from the air. Based upon two standards, ASTM F2101-19 and EN 14683:2019+AC, Sigma designed and built an automatically controlled test stand consisting of a control panel, hmi, filter apparatus, and test stand base upon which a commercially sourced lab hood was placed. Working with the standards and customers expert knowledge, Sigma sourced and created custom unique components of a high laboratory cleanliness to create the testing apparatus.

Customer: Global Fortune 100 Medical Device Manufacturer Industry: Health and Life Sciences
Sigma Design Selected to Develop New Concept in Wound Care Device Manufacturing
When a global medical device manufacturer needed help with advanced engineering and design, they reached out to Sigma Design. The 3-year program started within the realm of an R&D investigative program. Concepts trials and tests were performed to help validate the process and develop a manufacturable solution.
From start to finish Team Sigma worked with the R&D and company manufacturing teams from around the world to fine tune the solution for each location.
In the end, the program was a big success, and these workstations are being installed at medical device manufacturing sites worldwide.
Services Performed: Concept development, advanced engineering simulation and analysis, concept testing, detail design, material selection, ergonomics, safety, automation & controls, sensors, electronics, welding, machining and fabrication, pilot validation and testing. Followed by a large manufacturing order for production systems.

The Behavioral Spectrometer is a humane device that captures everything a research mouse does without having to watch and score hours of video recordings. Sigma designed, tested and manufactures this ‘mouse house’ in its New Product Manufacturing Center. 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.
This product has met with huge success in the research and pharmaceutical world including Rutgers University’s Department of Neuroscience and Cell Biology, Pfizer, and other global R&D laboratories for the development of new treatments and drugs. Additional systems have recently been shipped to a R&D laboratory in Austria.

A company was looking for a new tissue embedder and cryo system with unique features and capabilities. When Sigma Design Company took on the job they got all of that in a sleek and user-friendly design. Using photo realistic imaging and paraffin flow modeling in SolidWorks™, the designers analyzed various layouts and the human factors. These variables were meticulously checked in 3D prior to prototyping. All prototyping housing components were made in-house using Sigma’s 3D FDM printer.

Customer: Glen Mills, Inc. NJ
Industry: Medical Laboratory Devices
Sub Heading: Sigma Design Company improves the design of a medical device to improve cell culture and tissue engineering capabilities for laboratories.
Sigma Design Company can be your partner in not only design but also in the manufacture of your new product. Consider the story behind the Glen Mills/Zellwerk Z®RP Reactor System” – a cell disruptor and high-pressure homogenizer. With the discontinuation of their previous French Press manufacturer’s production, Glenn Mills Inc. needed to find a company that could redesign and manufacture the French Press directly for them. They found this in Sigma Design Company. Working with the original design, which was based on a 60 year old medical device, Sigma reverse engineered and redesigned the machine to have more features, better aesthetics, and compatibility with all of the older system’s accessories. This new design incorporated many of the skills Sigma excels at including: tight tolerance machine components, hydraulics, circuit board design, material properties and finishes. With a newly designed product, Sigma Design Company manufactures and assembles these units in our NJ facility, providing immediate customer support, and a short lead time to our customers.
Sigma is also the manufacturer of the French Press G-M™
