  1. Sitting Down With Synectic’s 2017 Summer Intern

    When people think of summer they think of hot days by the pool sipping cold drinks or a fun day with friends and family at the beach, but here at Synectic, summer signifies a new intern. Synectic’s highly sought after paid internship program is an excellent opportunity for young engineers to get valuable hands-on experience that will help them throughout their careers. After careful review of the many applicants, we chose Heather Stratica to intern with us this summer. Originally from New York, Heather is a Biomedical Engineering major, with a concentration in Biomedical Instrumentation, at Worchester Polytechnic Institute in Massachusetts. I had a chance to speak with Heather about why she chose to intern at Synectic and what her internship experience was like.

     

    Thank you for taking the time to speak with me today. I know all the projects here have kept you very busy the last few weeks. Starting off, let’s talk a little about your background. What made you pursue a career in engineering?

    HS: From a young age I noticed that I was naturally good at math and science and I really enjoyed those topics in school. Because of this, as I grew older, I began to take part in STEM and particularly women focused STEM programs to get a better understanding of what my options where in those fields. It didn’t take long before I realized I wanted to become an engineer and not just to design new things, but to have the general mindset of an engineer and have the ‘problem solver’ mentality. This mentality is something that has been useful in every aspect in my life and I’m glad to have chosen a path that has impacted me so positively.

    Heather, you’re originally from New York and go to school in Massachusetts, out of all the places you could have interned with, why did you choose Synectic?

    HS: My concentration is in biomedical instrumentation and Synectic’s main focus for years has been medical devices. This is exactly what I want to work with after college so I reached out and learned about the internship program. I thought it would be a great way to learn about what medical device engineers do at a company like Synectic.

    We are so happy you were able to spend your summer working at Synectic. As you are preparing to go back to your final year in school, how has your time here advanced your knowledge? 

    HS: Most of my engineering education has come from a classroom setting, with some projects thrown in as we assess mechanical and biomedical designs. My time at Synectic allowed me to utilize what I learned in school, in a ‘real world’ setting. Since it’s a rather small company, I learned a lot about how a medical device company actually functions and not just from the engineer’s perspective. I also participated in pilot production of a major product allowing me to participate in the entire process from concept to production. To me, all of this is valuable knowledge that can’t be taught in a classroom, and I am glad Synectic gave me the opportunity to gain this experience.

    Heather, given your experience while working with us, would you consider coming back to work at Synectic full time?

    HS: Yes, I would love to come back to Synectic! It’s a great atmosphere to work in and the projects are plentiful and intriguing. You are required to think outside-the-box and challenge yourself daily. One of the best parts about working at Synectic is that you get to see the entire concept to production process. It’s great to see all your hard work pay off when the product goes to market.

    We would love to have you back at Synectic as well. One last question that I’m sure everyone reading this wants to know. Tell me something about yourself and what you like to do outside work and school?

    HS: I am a first generation American scholar, as both of my parents emigrated from Romania and worked very hard to get where they are today, instilling in me a very strong work ethic. I’m from Wappingers Falls, NY and came from a very small high school where I had about 30 people in my graduating class. I swam competitively for about 8 years and just retired that this spring, however, I teach swim lessons to share my passion with others.

  4. How to Choose: The Truth About Resins

    By Scott Rishell, Design Engineer, Mack Molding and Kathleen Murray, Communications Manager, Synectic Engineering

    One of the largest advantages of choosing Synectic Engineering for your next project is its relationship with its parent company Mack Molding. As a leading custom plastics molder and contract manufacturer serving a range of markets – medical, industrial, transportation, energy/environment, computer/business and consumer – Mack’s customers are varied and so are their needs. Mack’s 95+ years of molding allows them to choose materials based on customer specifications, moldability of design, and cost. Choosing the right material early in the design process, streamlines the time and cost to market by picking the correct path every time. This a value add in the design cycle, for both our clients and our design process.

    To meet the diverse requirements presented by so many programs, Mack has vertically integrated services, including design, prototyping, supply chain management, machining, sheet metal fabrication, molding, painting, assembly, testing and even fulfillment. Working together, we are able to offer our client’s a full portfolio of services from concept to production. Synectic and Mack combined have over 130 years of knowledge and experience allowing us to stay competitive in an always changing market.

    One area where we often find the most distinctiveness is in resin selection. Mack has a wide portfolio of molded parts, and each is unique based on the customers’ requirements. Beyond aesthetics, like color, a material’s properties, processability and cost all play a key role in determining a resin’s suitability for an application. With thousands of grades to choose from, and new ones being developed to fill market niches, customers often turn to us to help them navigate the resin selection process.

    Here are some of our key considerations we weigh when making a selection:

    Mechanical Requirements
    A part’s strength requirements need to be considered as resin classes have various tensile strength, tensile modulus and elongation at break. Thermoplastic resins offer a variety of strength properties that can often be modified with fillers like glass or carbon fiber.

    Chemical Compatibility
    Many customers are concerned about how chemicals, including cleaning solvents and process reagents, interact with their resin selection. In these cases we consult published testing data from resin manufacturers that show a material’s performance in each chemical.  In some cases the data may not exist and testing with specific chemicals will be requested.

    Environmental Compatibility
    Parts that will be exposed to extreme hot or cold conditions need to be made with resins that are rated accordingly, making the long term service temperature and heat deflection temperature critical performance metrics. Other conditions to consider include exposure to UV light and high humidity.

    Commodity vs. Performance
    Whenever possible Mack strives to pair customer applications with commodity resin grades due to the inherent cost and availability advantages that come with higher volume raw material production.  Some projects call for specific properties – strength, heat resistance, etc. – which is where performance resins excel.

    Amorphous vs. Semi-crystalline
    Selecting amorphous resins can often be advantageous as they can provide wider processing windows and improved dimensional control due to their random molecular structure. They can be transparent and are compatible with many adhesives. Semi-crystalline materials offer improved mechanical and thermal properties but can be more difficult to process.

    Material Shrinkage
    The amount a resin shrinks during the molding process can have a huge impact on the ease of building a tool or developing a successful molding process. For this reason we try to select resins that have lower shrink rates whenever possible.

    Once all of these factors are accounted for, the list of suitable resins is typically cut down to a manageable number to consider. It is here that the Synectic and Mack team leverages its proficiency with particular materials, coupled with expertise in design and development, to make the final determination of a grade.

  5. Can You Escape? Synectic Survives Escape New Haven

    If you have not heard about the latest craze popping up everywhere, an escape room involves putting a group of people in a room with a scenario and a set amount of time in order to solve a series of puzzles to “escape” from the room. Escape New Haven offered the perfect opportunity to try out one of these rooms during our latest company outing.

    Synectic was split into two teams and given the following scenario: You are a crew of scavengers in space. You’ve discovered an abandoned space station orbiting a distant moon. If you’re lucky, you’ll be able to scavenge this station for its four valuable energy crystals. Find the crystals, and while you’re at it, also try to find out what’s happened here. Don’t let your oxygen run out, and keep an eye out for danger. You don’t want whatever happened to the crew to happen to you, too…

    Armed with only our wits, each team had 60 minutes to complete the task before us. Although neither team made it out on time (on average there is only a 20% success rate) we all had a fun afternoon filled with problem solving and team building. Which team did better, you ask? Remarkably, both Synectic teams were on the exact same puzzle when the clocked stopped, proving that no matter which of our engineers work on your project you will get the same results. If your team is facing a puzzling product development challenge, contact Synectic and we’ll develop the perfect solution. Let us demonstrate how we can bring your product development ideas to life.

  6. Synectic Celebrates a Lifetime of Achievements

     

    It is with mixed emotions that Synectic announces the retirement of Vinny Mata, one of our most distinguished senior product development engineers.

    I was able to sit down with Vinny one last time before he left. Here is what he had to say about his time at Synectic.

    Vinny, you have such a rich engineering background, what brought you to Synectic?

    VM: I was originally introduced to the previous owner of Synectic, Jeff Stein, through a mentor of mine. Over the years I worked with him on various projects, as a contractor, before I went into medical device design. Then, about 10 years ago, I was looking to leave the company I was work at and I asked Jeff if I could use him as a reference. Well, he did way more than offer me a good reference, he invited me to come work for him. I had really enjoyed, working with him in the past, so it seemed like the perfect opportunity. Synectic offered the fun, family-like environment that I was looking for.

    I’m so glad things worked out the way they did. You have worked on some pretty amazing projects throughout the years. What were some of your favorites while working here?

    VM: One of my favorite projects was working on the 5mm laparoscopic stapler from Just Right surgical. The client challenged us to push the project to the limits with design and materials. Our team rose to the challenge and we were able to change the technology, making a significant impact in pediatric laparoscopic technology.

     

    Vinny, you have definitely left your mark on this place and I can assure you, you will not be forgotten.  What advice can you give to an engineering that is just starting their career?

    VM: I recommend finding a company that nurtures and encourages you to master every aspect of product development from engineering to manufacturing. Seek out an environment where you can simultaneously contribute and expand your mind. You want driven colleagues who have a willing attitude to learn from each other and gladly share their knowledge. At Synectic the senior engineers spend time mentoring the junior engineers, encourage questions, and are willing to try a new approach. Even with all our years’ experience, we are still open to learning from the younger generation just entering the field. Synectic is also great for those looking to go into medical device development. You are not just working on one project in one specialty all the time. We have to learn all the anatomical systems and the projects change quite often. We learn everything from cardiovascular to tissue management and must know how to tie that into mechanical engineering.

     

    Thank you so much for taking the time to chat with me. We are really happy that you chose to work at Synectic and we are sorry to see you go. What do you plan to do with your time now that you are retiring?

    VM: I am an avid fisher and boater and I plan to do a lot more of both.

    Good luck Vinny in wherever life brings you to next!

  7. How to Choose: The Truth About Fixed-Fee vs. Time-and-Materials

    In the world of medical product development, OEMs looking to keep costs controlled are leaning more and more towards outsourcing design or consulting services. As with any client/vendor relationship, the financial arrangement between the two companies can cause the most friction. When deciding what arrangement works best for both parties, most often the choices can be broken down into two categories: fixed-fee vs. time-and-materials. Both involve an agreement centered on a predefined scope, but the difference is that in fixed-fee the amount agreed upon is preset, while in a time-and-materials setting the vendor is paid for hours worked.

    Let’s break it down further:

    One of the greatest advantages, to the client, in a fixed-fee arrangement, is transparency of cost. They are less likely to get “sticker shock” at the end of the project and can budget accordingly. This type of arrangement forces the vendor to work as efficiently as possible and focus on the end game. If the vendor completes the scope of work on time then the agreed price is paid, but if they run over time, they are still contractually obligated to complete the work, while simultaneously eating any additional cost. In order for a vendor to stay in the black with fixed-fee projects, they must focus on quoting small, manageable scopes of work that ultimately mitigate risk and can be performed on time. Where the vendor can run into trouble is when they don’t adequately define the scope parameters to the client, as anything outside the scope is an extra cost. To that end, OEMs need to ensure that the deliverables and quality expectations are clearly outlined at the start of the project.

    On the flip side, with time-and-materials the advantage lies in the dynamic control the client has over the vendor’s work.  The vendor in turn is incentivized to keep up-selling the product to lengthen the scope. The flexibility of time and material however, does have a downside: without a clearly defined scope, it can be very easy for a project to go off track leaving the OEM with a large bill and little to show for it. The key to success in this type of agreement is a clear understanding, by both parties, of what the required tasks are and how long they should take to complete.

    As we have just seen, there are advantages to both agreements and deciding which would best fit your organization can be difficult. OEMs need to take into consideration their business philosophy, product design history, and the structure of their organization. Here are some things to keep in mind when deciding which way your organization should lean.

    Traits that make an organization more suited for a fixed-fee arrangement include:

    • Ability to sign off on large milestone payments without getting bogged down in red tape
    • Time driven results
    • An organization based on trust where open communication is valued
    • Trust in the vendor’s process to achieve the best results

    Traits that make an organization more suited for time-and-materials arrangement:

    • Require freedom to change the scope at will, regardless of the cost
    • Unable to define the next scope without previous results
    • Preference for managing all aspects of product development
    • Desire to make decisions based on large data samples
    • More comfortable with incremental payments instead of one large lump sum
    • Need a wide array of choices and an overall consensus before making a decision

    As seen above, there are many factors that go into choosing which payment arrangement is right for your company; a harrowing endeavor for OEMs new to the process. This is why we offer the Synectic Solution. With over 38 years of experience and a senior staff of engineers, we can accommodate even the most complex projects and demanding clients. We not only have extensive experience in medical device design, but our talents include aerospace, capital equipment, material handling, and automotive as well.
