Recently Mack retiree Marty Oakland stopped by to give current employees a fly fishing casting lesson. Besides an impressive 36-year tenure with us, today Marty a fishing guide and proprietor of Arlington Vermont’s Quill Gordon Bed & Breakfast along with his wife, Valerie. So on a sunny Tuesday afternoon, today’s Mack team learned how to shoot the line from a Mack legend, catching some grass and even our camera man in the process!

It has come to Mack’s attention residents in the Arlington, Vt., community have been receiving phone calls from purported solar companies, and potentially other services, that appear on caller ID to be coming from a phone number associated with Mack.
Mack is committed to being a good steward of the community, including its protection from fraud, and has alerted its phone carrier’s technical and fraud teams of the calls. It is important to note these calls are not originating from the Mack phone exchange or the Company’s network. Unfortunately, in the age of Voice over Internet Protocol (VOIP) it is easy for callers to deliberately falsify the information transmitted to caller ID to disguise their identity. Known as “spoofing,” this technique is often used to trick someone into giving away personal information that can be used for fraudulent activity.
Spoofing for fraudulent gain is prohibited in the U.S., which is why Mack is working with its carrier to reduce the risk of being spoofed. This activity is hard to combat, however, and the best way to defend against it is to be informed and vigilant. Never offer personal information to an unexpected caller, and if you receive a call from someone claiming to be from a familiar company or government agency hang up and call a verified number for that entity.

Despite its best efforts, Stella, the blizzard of 2017, couldn’t keep the Mack team from working hard for our customers. Get out of the cold and get an inside look at what was happening at Mack during the big Nor’easter. And don’t forget, you can get a look at the Vermont weather everyday by checking out the Mack Mountain Cam at http://www.mack.com/mack-mountain-cam/.

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. To meet the diverse requirements presented by costumer programs, Mack has vertically integrated services, including design, prototyping, supply chain management, machining, sheet metal fabrication, molding, painting, assembly, testing and even fulfillment. 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 Mack to help them navigate the resin selection process.
Here are some of the key considerations the Mack team makes when making a selection:
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.
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.
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.
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 Mack team leverages its proficiency with particular materials, coupled with expertise in supply chain management, to make the final determination of a grade.
If you have a part you are ready to put into production, would like to learn more about resin selection or are interested in any of Mack’s vertically integrated services, please visit us at www.mack.com or e-mail our team email@example.com.
Scott Rishell is the technical lead on several programs at Mack, developing part designs for production processes. He works with customers to diagnose and implement solutions for design for manufacturability (DFM) issues, as well as reduce manufacturing costs through part simplification and process improvements. He has established an intimate knowledge of design, material selection, tooling and specialty processes for injection molding, including structural foam, and internal and external gas assist. Prior to his current role, Scott was a program manager in the Mack’s medical business, where he gained unique customer experience insights. He has a bachelor of science in mechanical engineering from the Rochester Institute of Technology.
