  1. Stainless Steel Advantages

    Leave a Comment

    APM Hexseal offers a variety of materials for our sealing solutions to suit the requirements of any application. However, stainless steel is our default material as it provides many benefits when compared to other common metals, making it ideal for various sealing applications across many industries.

    Stainless Steel Fasteners

    Advantages of Stainless Steel

    There are many advantages of stainless steel, one of the most obvious being its resistance to corrosion. This ability comes from 10.5% of its weight being made up of chromium, which creates an invisible chromium-oxide film on the surface, giving it the ability to self repair in the presence of oxygen. Corrosion resistance can be enhanced by increasing the chromium content or by adding other elements such as nickel, molybdenum, and titanium.

    Stainless steel has a number of other advantages, including:

    • Longer Life Span
    • Strength
    • Temperature Resistance
    • 100% Recyclable
    • Low Cost
    • Aesthetic Appeal
    • High Quality
    • Low Maintenance
    • Hygiene

    These combined advantages make stainless steel ideal for use in fasteners, screws, and other sealing applications.

    Stainless Steel vs. Other Common Metals

    There are many other metals that offer different features for use in sealing applications; however stainless steel offers many benefits over these. These metals include:

    • Other Grades of Steel. Steel can contain trace amounts of other elements such as manganese, chromium, nickel, and more, that each affect the properties of the alloy. Steel is a hard, strong, durable, and malleable alloy composed of iron and carbon.
    • Aluminum. Similar to stainless steel, aluminum offers corrosion resistance; however it is weaker against certain elements. This nonmagnetic metal is 1/3 the weight of steel, is ductile with high heat, and offers electric conductivity.
    • Chrome. Chrome offers corrosion resistance and a pleasant appearance, but it is an expensive alloy to use.
    • Silicon Bronze. Made up of silicon, tin, and copper, this material is often used in marine environments due to its corrosion resistance and high strength; however, it is an expensive material.
    • Copper. Copper is nonmagnetic and offers corrosion resistance, heat and electrical conductivity, and low to average strength. Strength can be increased by adding other metals.
    • Brass. Brass is a nonmagnetic alloy that offers electrical conductivity, corrosion resistance, and low to average strength.
    • Titanium. Titanium is a gray, low density, lightweight, corrosion resistant, and high strength metal.

  4. APM Hexseal’s Updated Operations During the Pandemic

    Leave a Comment

    APM Hexseal is an essential supplier of components used in the manufacture of a wide variety of medical equipment, including ventilators, hospital beds, and medical instrumentation. As such, we had to formulate a plan to keep our plant open and our lines running to insure that the supply chain for critical medical equipment was not disrupted. To achieve this, we established a number of safety protocols and procedures that allowed us to maintain the high level of service our customers expect, while ensuring the safety of our valuable employees and customers.

    How We Worked Through

    At APM Hexseal, we are dedicated to finding innovative solutions to a variety of challenges, including the ones that arose at the onset of the COVID-19 pandemic. To accommodate social distancing and sanitation protocols recommended by the CDC, we put our creative minds to work to best keep everyone safe and healthy. We created written guidelines and instructions for our employees, in multiple languages, that are displayed throughout the building.

    New Methods of Communication

    APM Hexseal established a variety of remote communication methods to ensure our customers continued to receive the highest level of service during the COVID-19 pandemic. Through the use of video calls, telephone conversations, and other remote support methods, we were able to help customers select and troubleshoot sealing solutions. 

    Additionally, in an effort to reduce interpersonal contact, we also divided the building up by geography, and employees utilized only the entrance, exit, break areas and restroom in their designated section.

    Drop Locations

    To ensure our employees maintained safe social distance, we established drop and transfer locations throughout our manufacturing plant and office. This allowed our staff to maintain a minimum of 6 feet of space between them at all times, while being able to safely hand off files, paperwork, documents, and other materials.

    Fewer Personnel

    At the height of the pandemic’s impact, we divided our entire work- force into teams, and only certain teams were in the building on certain days. We created this schedule to ensure that teams stayed together while preventing cross over. Utilizing this process meant that if one person were to get sick, only that team would be removed—not the entire work- force. This careful management of our on-site staff schedule and rotation of teams was what enabled us to continue manufacturing and delivering orders to our customers during the peak of the pandemic.

    Frequent Sanitization

    We provided all required PPE to our staff and they were instructed on how to utilize them. Additionally, all employees were given sanitizing wipes, gel, and hand cream to use throughout the day.

    Temperature Checks

    We checked all of our workers’ temperatures at the beginning of each shift and during the course of shifts if any employee showed signs of illness.

    Looking to the Future

    Moving forward, APM Hexseal’s highest priorities continue to be keeping our manufacturing lines running at full capacity and protecting the health and safety of our team and business partners. As such, while maintaining a number of the new protocols we implemented at the height of the pandemic, we are also applying more permanent solutions.

    Our team is currently re-mapping our factory floor to be more COVID suitable. This entails re-positioning some of our largest and heaviest pieces of manufacturing equipment, including our mold presses. This is a huge undertaking but we feel it is necessary to ensure the safety of our employees and the continuity of our production.  After this work is complete, our press operators will be significantly spread apart to ensure the necessary 6-foot social distance protocol. By rearranging our plant floor in this manner, we are eliminating the need to separate our workforce into teams, and therefore, can continue to run at full capacity even if new pandemic-related business restrictions were to arise.

  5. COVID-19: APM Hexseal’s Sealing Solutions for Mission-Critical Applications

    Leave a Comment

    In the midst of the COVID-19 pandemic, businesses in many industries have pressed on to fulfill critical needs throughout our society. As an essential business, APM Hexseal has proudly continued to manufacture mission-critical components for a variety of medical, military, and industrial applications. During this trying time, we’ve supplied thousands of the fasteners and sealing boots used to build ventilators, hospital beds, and COVID-19 test units while taking measures in our facility to ensure the safety of our team and our customers.

    COVID-19 Response Equipment & Challenges

    Medical equipment is right in the middle of a storm of germs: it’s exposed to numerous patients and handled by multiple medical professionals who carry bacteria on their gloved hands. Those bacteria can also hitch a ride from room to room on equipment as it travels throughout a hospital or medical center.

    Because of this, even without the threat of COVID-19, medical equipment is subject to constant cleaning; the sanitization schedule is even more intense as hospitals and emergency rooms battle this especially contagious virus. Chemicals and high pressure make the wash-downs effective, but they also put the equipment at risk of damage from water and sanitizing chemicals. It’s essential to protect electronics and vulnerable components to keep them functioning reliably, otherwise a single cleaning could ruin an expensive and life saving tool or machine.

    APM Hexseal’s sealing boots and hardware are made for this purpose. Because our products are resistant to many sanitizing chemicals, they can safely be used for a wide range of equipment—even those items that must be sanitized multiple times a day.

    APM Hexseal Sealing Solutions Can Meet These Demands

    Medical equipment is often delicate, but health care professionals rely on it to work flawlessly when they need it most. Many of the tools and machines are expensive, and they have to last through repeated use and cleaning. Our products are corrosion-resistant, and they protect against chemicals, water,  extreme weather  and pressure, sealing out the hazards while extending the life of a multitude of electronic components.

    Since 1947, our sealing solutions have been proudly Made in the USA at our facility in Englewood, NJ. In that time, we’ve accumulated more than 100 patents and served more than 200,000 customers. No matter the application, we can help you find a sealing solution.

  8. How to Match Switches With Boots

    Leave a Comment

    Sealing Boots

    When working with electrical equipment, it is critical that the components be protected from contaminants and harsh environmental conditions.

    This is why APM Hexseal originally developed and patented the first sealing boots on the market, designed to shield electrical components from the incursion of unwanted moisture, pollutants, and other factors that could harm sensitive electrical components. In order to meet the needs of a comprehensive array of applications, APM Hexseal has since engineered a variety of sealing solutions in a wide range of sizes, shapes, and functions.

    Switches are a particularly crucial aspect of an electrical system and are often the component most exposed to compromising conditions.

    Switches must be readily accessible since they are used to initiate, regulate or disconnect the flow of electricity through a system. This often results in design compromises that place switches in unprotected environments. Choosing an ideal sealing boot to fit your switches will help protect your equipment from unwanted environmental influences and contamination.

    Type of Switch & Dimensional Values

    In order to select the right boot for your switch, it is important to first consider the function and dimensions of the switch itself.

    Types of Sealing Boots InfographicToggles

    Toggles come in numerous designs, shapes, and sizes, and are often used for simple on/off functions. A toggle switch operates in two positions—connected and disconnected—often through the use of a handle or lever. To select the appropriate sealing boot for a toggle, it is especially important to consider the overall dimensions, lever motion, and thread size of the toggle switch.

    Push Buttons

    A push button switch controls the flow of electricity through a button connected to an internal spring mechanism. Measure the diameter, thread size, and necessary actuation force to choose the right sealing solution for a push button switch.

    Rotaries

    Rotary switches are operated using a turning motion. These switches are often used for switches that require more than two operating positions. To choose the correct boot for a rotary switch, consider the diameter, thread size, and functional requirements of the switch.

    Rockers

    Rocker switches are similar to toggle switches in that they are used for on/off functions. The primary difference is that they use a flat rocker design rather than a lever or handle to operate the switch. They are often found on computer equipment and in modern light switch designs. To ensure the proper boot for a rocker switch, take accurate measurements of the rocker and its operational movement.

    Circuit Breakers

    Circuit breakers are designed to switch automatically to the off position when excess current is detected. They are available in a wide variety of styles and configurations, so it is important to obtain precise measurements when selecting the best boot for your circuit breaker.

    Switch Application and Frequency of Use

    In addition to analyzing the design and dimensions of the switch, it is essential to take into account the exact application and frequency of use. High-use switches with a wide range of motion may necessitate a more durable or flexible boot material (elastomer).

    Depending on the application, equipment may be exposed to harsh conditions, including:

    • Corrosive chemicals
    • Extreme temperatures
    • Moisture
    • Saltwater
    • UV radiation

    It is important to have a thorough understanding of the elements to which the boot will be exposed to determine the best material. For example, a standard silicone boot may be ideal for frequent outdoor use due to its high durability and flexible nature, but would not withstand long-term exposure to certain corrosive chemicals or saltwater.

    Sealing boots can be customized to fit the needs of a wide range of applications. The material, size, shape, and even color can be tailored to protect your switches while enabling the highest degree of operability.

    Switch Samples and Durometer Testing

    At APM Hexseal, we are dedicated to ensuring that you have the right boot for your switch. Our experienced and knowledgeable staff will take into account the physical requirements of your application and use switch samples to ensure ideal protection and switch operation. With durometer testing, we ascertain the perfect material thickness, flexibility, and strength for each individual switch, so our customers know they are getting the best boot available.

    Installation Details

    It is important to consider the way the switch will be mounted to ensure adequate fit and function of the protective boot. The thickness of the surrounding panel, wiring, and dimensions all come into play. A thin panel, for example, requires a different style of installation to prevent the boot from interfering with the internal operations of the switch and surrounding equipment.

    Sealing Boots From APM Hexseal

    For over 70 years, APM Hexseal has been an innovative designer of superior sealing solutions. Our patented sealing boot design established an industry standard, and we have been improving and enhancing our designs ever since. APM Hexseal’s sealing boots and bushing seals provide reliable protection for both external and internal electrical components to ensure safe and dependable system operation.
