    Click to ExpandFLATBED VS. ROTARY DIE CUTTING - DIE CUT GASKETS” data-lazy-src=

    Gaskets are important components in construction and machinery, as they function as mechanical seals to prevent fluid and gas leaks. While some gaskets are manufactured through waterjet cutting, others are created via die cutting. Die-cut gaskets provide a seal between two distinct surfaces, filling the space when a sufficient amount of bolt load produces a compressive force.

    Die cutting is one of the most effective methods for splitting, molding, and forming flexible materials, making it the technique of choice among manufacturers. It delivers a high level of precision and can cut shapes easily.

    Rotary and flatbed die cutting are two of the most common methods of die cutting, and deciding which method to use for die cut gaskets can be tricky. This article will discuss the fundamentals and distinctions between rotary and flatbed die cutting.

    Flatbed Die Cutting

    Flatbed die cutting is the method of cutting or perforating the required shape from the raw material with a hydraulic flatbed press. The machines have a flat, permanent base and a movable head, and the cutting die is commonly composed of sharp strips of metal called steel rule.

    The raw material is fed along the base while the press is vertically pushed down to produce the cut. The vertical motion shapes thicker materials, resulting in minimal material bending.

    The flatbed die-cutting process is typically utilized for four primary reasons:

    • If the product is thick
    • If the material is only accessible in sheet form
    • If the order is low-volume
    • If budget is a consideration

    Flatbed die cutters are frequently used in custom manufacturing projects due to their exceptional workability and cost-effectiveness. Moreover, recent technology advances in flatbed die cutter equipment, such as laser cutting, digital printing, and design refinement, provide manufacturers with more options.

    Rotary Die Cutting

    Rotary die cutting uses a cylindrical die to cut shapes out of material. The cutters are equipped with blades to cut the required form in a circular rotating motion around the full circumference of the cylinder.

    The process begins by feeding the raw material at a very high speed between two rolling cylinders. The rolling die cuts off the shape with excellent tolerance and precision and generates less waste than the flatbed die cutting.

    The rotary die-cutting process can produce exceedingly complex multilayer parts due to its capacity to perform multiple functions during the same cycle. It also allows cutting each piece completely through or kiss cutting, where a paper liner is left to hold each piece together until it is required.

    Manufacturers usually utilize rotary die-cutting presses for the following circumstances:

    • If the product is thin
    • If the required quantity is high
    • If the project necessitates a kiss cut
    • If the design has precise tolerances

    Rotary die cutting is suitable in areas where metal and plastic sheets must be precisely the same size. It is also recommended for producing adhesive sheets that suit identically sized objects and printing bandages in a precise manner. In addition, it accommodates a vast array of materials, including thin metal, plastic, paper, foam, cloth, and laminates.

    Choose Mercer Gasket & Shim for Quality Die Cut Gaskets Solutions

    Rotary die cutting utilizes a cylinder to cut shapes from a material, whereas flatbed die cutting uses a hydraulic flatbed press to make the desired shape. The flatbed die-cutting method is excellent for low-volume projects. On the other hand, the rotary die-cutting technique is suitable for large production due to its ability to make many cuts simultaneously.

  2. Silicone Rubber Gasket 101 | Materials, Properties, Applications

    Leave a Comment

    What Are Silicone Rubber Gaskets?

    Gaskets are mechanical seals used to fill in the spaces between two mated surfaces. They are engineered to prevent fluids (gas or liquid) from leaking out of or into the system between the two surfaces while under compression. In some assemblies, they serve as a barrier that keeps two components separated to protect them against friction damage.

    These sealing devices can be made from a wide range of materials depending on the requirements and restrictions of the application. One of the most commonly used is silicone rubber. It exhibits many advantageous characteristics that make it suitable for various industrial and commercial applications. For example, its excellent resistance to extreme temperatures, ozone, and ultraviolet (UV) radiation enables it to be used in outdoor environments without fear of premature degradation.

    Silicone Rubber Gaskets Types

    Types of Silicone Gasket Materials

    Silicone rubber comes in many types, grades, and forms to suit different applications. The ones commonly used to make gaskets are:

    • Solid silicone rubber. This material has a dense molecular structure. It can have low or high durometers. The former is suitable for seals with low closure force requirements, while the latter is suitable for seals with high closure force requirements.
    • Sponge silicone rubber. This material has a cellular structure that provides some cushioning and padding properties. It is available in two basic types: open-cell and closed-cell. Open-cell sponge silicone has interconnected pockets that allow air, chemicals, and water to pass through when it is uncompressed. Closed-cell sponge silicone has pockets that are filled with nitrogen to prevent anything from passing through it.
    • Foam silicone rubber. This material offers flame resistance. It is available in soft, medium, firm, and extra-firm grades and open-cell, closed-cell, and combined open-cell/closed-cell variations.
    • Liquid silicone rubber (LSR). This material is a two-part material system that must be mixed and heat cured before use. It offers fast and inexpensive molding operations, clean curing operations, and low durometer options.

    These silicone rubber gasket materials can be made in various grades, such as FDA-compliant, UL-compliant, and MIL-SPEC, and shaped into sheet, roll, and other standard or custom profile forms to meet different industry and application requirements.

    Why Use Silicone Rubber Gaskets

    Why Use Silicone Rubber?

    Silicone rubber exhibits many properties that make it ideal for use in gaskets, such as:

    • Resilience over a broad temperature range. Silicone rubber is resistant to chemicals, moisture, oxygen, ozone, and sunlight, and it maintains these qualities in both extremely low and extremely high temperatures.
    • Resistance to permanent compression set. Silicone rubber will return to its original shape after being subjected to compressive forces.
    • Availability in various durometers, colors, and specialty grades. Silicone rubber comes in numerous hardness levels, colors, and grades, so it can be used for many applications.

  3. Gasket vs. O-Ring: Differences and Common Applications

    Leave a Comment
    Soft Gaskets
    O-Rings

    While gaskets and O-rings serve a similar purpose of sealing out air or liquid, the two are designed for different situations and vary in appearance. Here, the team at Mercer Gasket & Shim will explain the differences between these sealing solutions to help you determine the best one for your application.

    Gaskets vs O Rings overview

    What Are Gaskets and O-Rings?

    Gaskets are flat pieces of material used to make a seal between two flat surfaces, usually with a bolted joint. O-rings are round, ring-shaped pieces that must set in a groove to create a seal between two parts. While gaskets are most commonly circles, they are also manufactured in a variety of other shapes. Both gaskets and O-rings are made using flexible materials, but gaskets can also be made out of other rigid polymers and metals. The thickness of an O-ring can be customized to fit unique specifications, while gaskets may be layered with different coatings to work best for various applications.

    Common Applications for Gaskets

    • Electrical motors, power generators, and transformers
    • Electronics
    • Handheld communication devices
    • Telecommunications equipment
    • Aerospace and defense industry
    • Transportation and automotive
    • Medical devices
    • Food and beverage industry

    Common Applications for O-Rings

    • Hydraulic seals
    • Pipe joints
    • Equipment with fluid seal points
    • HVAC – Heating, Ventilation, and Air Conditioning
    • Oil seals
    • Fuel systems
    • Food processing
    • Pharmaceutical and medical industry
    • Pulp and paper industry
    Gaskets O Rings Applications

    Choosing the Best for Your Application

    When deciding whether a gasket or O-ring is best for your application, consider the environment and function of the seal. When choosing the best seal, look for features such as shape, temperature, and pressure.

    When a non-circular joint requires a good seal, an O-ring would be difficult to use because of its round shape. Gaskets can be customized to almost any shape, allowing them to work as a seal for a larger variety of applications.

    The operating temperature of equipment will determine the best material to use for manufacturing the O-ring or gasket. While both can withstand a wide range of temperatures, gaskets are best for extreme temperature situations. However, O-rings perform better than gaskets in applications with extreme pressure.

  4. 6 Tips for Choosing the Best Gasket – Materials, Types, Uses

    Leave a Comment

    Everything from the size of the gasket to its ability to withstand degradation and damage plays a role in how well it can stop the escape of air, gas, water, or other fluids. Gaskets are placed between two flush surfaces that have a channel for fluid movement. Because the two surfaces might not be perfectly flush or straight, they’re going to have gaps that fluid can move through. Gaskets correct those gaps by being compressed between the two surfaces to effectively eliminate any leakage pathway.

    Custom Corrugated Gaskets
    Soft Gaskets
    Shims

    Key Gasket Selection Factors — Gasket Materials, Types, and Uses

    Some factors that buyers should consider as they purchase gaskets include:

    • The amount of force the two surfaces will exude on the gasket
    • The degree of surface unevenness (which dictates how thick the gasket should be)
    • The fluids and any ambient contaminants
    • The compressibility of the gasket material

    If you know all the details of the application environment, you can choose gasket materials that withstand exposure to water, acidic or alkaline chemicals, oxidation, and more factors as needed. You can also pick gaskets with the right thickness, longevity, and malleability.

    6 Tips for Choosing the Best Gasket – Materials, Types, Uses

    Selecting the right characteristics prevents gasket failure. These parts can fail if they’re exposed to chemicals that degrade the material or if the forces acting on the gasket are too great. This guide will focus on the six most important tips for choosing the perfect gasket for your needs:


    1. Selecting the Right Gasket Material

    . Metallic Gaskets

    Metallic Gaskets

    Metal gaskets work best in extremely high-pressure applications. They create an initial line contact or contain the fluid through wedging once the two flush connection surfaces touch. Metal gaskets are also known as ring gaskets, and have either an ovular or octagonal cross-section. Octagonal cross sections provide a great deal of strength in the face of high pressure, such as the BX type that can handle 20,000 psi. Metal gaskets are commonly used in oil and gas industrial systems and secured with high-tension bolting.

    Popular materials for metallic gaskets include:

    • Inconel
    • Low carbon steel
    • Monel
    • Stainless steel

     

    . Non-Metallic/Soft Gaskets

    Non Metallic Gaskets

    Non-metallic, or soft, gaskets, compress between two surfaces with little tension or pressure. This makes them ideal for applications where the fluid contents have low pressure levels and can’t force a leak pathway through the gasket. Soft gaskets are affordable, easy to find in different materials and specifications, and able to be used in low-temperature applications.

    One common non-metallic material option, graphite, can also be used in high-temperature applications up to 500°C. These gaskets come in full face varieties, which cover the entire face of a connecting surface, and inside bolt circle gaskets, which cover a smaller ring of surface area on the face; one common application for full face gaskets is temporarily connecting utility lines.

    Popular materials for non-metal gaskets include:

    • Compressed Non-Asbestos Fiber (CNAF)
    • Graphite
    • Polytetrafluoroethylene (PTFE)
    • Rubber
    • Teflon

    . Semi-Metallic/Composite Gaskets

    Semi Metallic Gaskets

    Composite gaskets use both metal and non-metal materials, giving them the ability to provide a reliable seal in a variety of environments with different pressure and temperature factors. They are commonly used in male-female, raised face, and tongue-and-groove flanges. Because they contain less metal, they are often more affordable.

    Three popular types of composite gaskets are:

     

    Other Material Types

    • Elastomeric: Elastomers are polymers with similar stretch and flexibility to rubber. Elastomeric gaskets are commonly used in utility applications alongside non-metallic gaskets. While these gaskets are elastic and can be deformed, they’re incompressible and can’t reduce in volume.
    • Fibrous: Fibrous gaskets are another specialized type of non-metallic gasket. This category includes materials such as aramid, carbon, and glass fibers, cork, mica, and more. Each material offers very distinct properties.

    2. Evaluating Fluid Temperature, Corrosive Properties, and Pressure

    When gaskets aren’t properly aligned to the application environment’s temperature, materials, or pressure, they are at an increased risk of failure. Each gasket’s material is best suited for a specific range of fluid or ambient temperature; silicone, for example, has a much wider temperature range (-30°F to 350°F) than neoprene, which is only viable at temperatures between 30°F and 180°F. One of the first considerations when choosing a gasket material is to know the minimum and maximum operating temperatures of the fluid.

    The chemical makeup of the contained fluids should also determine which material your gasket has. Factors such as pH level, oil or water content, oxidation qualities, and more can corrode or destroy different materials through regular or irregular exposure.

    Gaskets also perform differently depending on the pressure levels. Non-metallic gaskets, which can provide a compressed seal at relatively low pressures, cannot provide adequate resistance if the contained fluid is too pressurized; the fluid can force a path through the gasket’s seal. Synthetic rubbers, for example, often have a cap of 60 psi for reliable performance. Metallic gaskets, on the other hand, are well matched to the extremely high pressures in oil and gas processing plants.

    3. Choosing the Best Types of Gaskets

    Once you know which material is best for the end application, you can select the right type, or structure, of the gasket. Some popular varieties include:

    • Jacketed Gaskets: These have a soft non-metallic interior and a metallic coating. Jacketed gaskets are available in many varieties, such as single- or double-jackets (which have a coating on one or both sides), corrugated jackets, and more. The metallic coating gives non-metallic gaskets better resistance to damage.
    • Solid Gaskets: These solid metal gaskets are extremely durable, but they require a lot of compression force to create a seal.
    • Spiral Wound Gaskets: This gasket style has windings of metallic materials in soft, non-metallic gaskets, which combines both resistance to damage and flexibility. Piping and pumping systems often use spiral wound gaskets because of the reliable seal.
    • Kammprofile Gaskets: These have a metal core surrounded by non-metal material on the top and bottom. It can create a tight seal along the gasket’s edge with extra reinforcement. They’re also easier to repair than comparable composite gaskets.

    4. Talking to a Gasket Design Engineer

    Working with a gasket design engineer is an excellent choice for creating a custom gasket for unique applications or for expert assistance in selecting the features your system needs. If you choose the wrong materials, design style, and type, you may degrade the life span of the surrounding system. Further, mass manufacturing a flawed gasket type can result in a failed project or excessive expenses. Talk to a gasket design engineer about your design specifications and environmental factors that should shape the final product.

    5. Testing for Gasket Performance

    There are multiple factors to test on a new gasket design to ensure the materials, specifications, and style create an adequate and cost-effective seal. Regulatory or standardizing organizations like Underwriters Laboratories set objective standards that industrial and commercial parts must meet to be safe for sale or use. The same organizations often establish what sort of tests or testing conditions are necessary to certify that a product is safe. These tests assess a gasket’s ability to withstand temperature, chemicals, pressure, and compression to retain a seal.

    6. Choosing the Right Gasket Manufacturer

    The right manufacturer is essential for ensuring the material success of your project. Look for manufacturers that have experience creating gaskets for the industries or markets you serve. It’s also important to choose a manufacturer with established design, testing, and inspection capabilities, so the final product is high quality and reliable.

  5. Food Grade Gaskets • Material Selection Guide | Fda Approved

    Leave a Comment

    Food grade gaskets play a vital role in consumer safety, helping to maintain the sterility of consumable products. Manufacturers typically utilize these gaskets across a wide range of food-production applications to prevent contamination.

    One of the most important applications for gaskets is food production; compromising the safety of food and beverages can threaten entire populations. Recent outbreaks of E. coli and other bacteria have forced companies to recall their products to prevent widespread illnesses or even death for some consumers.

    For compliance and safety, companies need gaskets that adhere to the strictest FDA and USDA guidelines. A specialized rubber gasket ensures no food or beverage is contaminated during any process condition. These gaskets are fabricated from materials that maintain the highest levels of sterility.

    Rubber Gaskets And Washers
    Sanitary Gasket

    Food grade gaskets offer a fair amount of flexibility compared to gaskets manufactured for other industries. At our ISO 9001:2015-certified facilities, we offer the following methods of gasket cutting:

    At Mercer Gasket, we have been specializing in the production of custom precision gaskets for 100 years. Our engineers work closely with every client to assist in the entire production process, including material selection, computer-aided design, and computerized reverse engineering. Over the years, our clients have continually trusted us to provide high-quality gasket solutions for even the most challenging projects.

    Types of Food Grade Gasket Materials

    There are a variety of food grade rubber gasket material options, each with its own unique characteristics.

    Silicone

    For applications requiring exposure to extreme heat, silicone is a popular option. It can withstand temperatures of up to 450° F, while still functioning well in temperatures as low as -67° F. This material is often translucent, but it is also available in gray, white, and red. Read More

    PTFE/Teflon

    Like silicone, PTFE offers high levels of temperature resistance. It also provides significant anti-abrasion and anti-stick properties. This synthetic fluoropolymer is very malleable, and it is often one of the most desirable materials for food grade gaskets. Read More

    EPDM Rubber

    Ideal for situations requiring exposure to the elements, EPDM rubber is resistant to UV light and doesn’t break down in extreme weather. As such, it is a popular choice for food production in agricultural settings such as grain silos. This material is both flexible and strong, and it holds up well even when exposed to oily substances. EPDM rubber is typically black in color and provides reliable service in temperatures of -40° F to 250° F.

    Nitrile (NBR, Buna-N)

    One of the biggest strengths of FDA Nitrile Rubber is its resistance to oil. This is particularly beneficial in the food industry since it will function well even when exposed to greasy or oily foods, particularly vegetable oils and animal fats. Nitrile can withstand temperatures ranging from -40° F to 212° F. It is most often available in black or white color options.

    Choosing the Best Gasket Design and Materials

    Sanitary Gasket

    When compared to gaskets manufactured for the pharmaceutical industry, gaskets for the food and beverage sector have incrementally greater flexibility in design. Pharma regulations indicate that no substitutions can be made in gasket production; however, food industry gaskets can be designed with material substitutes for certain applications.

    Even so, the materials for the vast majority of food and beverage gaskets have been predetermined by industry customers. While gasket manufacturers are ready and willing to provide advice, most clients select the materials they need according to size, temperature, application, media, and pressure (STAMP).

    One of the most frequently used gasket types in food production is the PTFE gasket, or Teflon® gasket. Known throughout many industries for its dielectric and non-stick properties, most PTFE resins are FDA-approved for food-related applications. Other frequently used materials for food and beverage gaskets include silicone and EPDM rubber. Mercer stocks a full line of sanitary gaskets and we are also able to create many other custom gaskets using the materials above.

     

    Compliance for Quality

    Every gasket-purchasing client needs to know their products can be delivered at the highest quality standards and without contamination. Manufacturers need to ensure contamination-free products, but the need for confirmable quality assurance goes beyond that.

    Gaskets and seals for the food and beverage industry need to follow strict governmental regulations and industry standards, including:

    • Food & Drug Administration (FDA). The FDA publishes regulations that include which manufactured materials can come in contact with food and beverage products.
    • United States Department of Agriculture (USDA). This organization oversees packaging materials and equipment used in meat and poultry processing.
    • United States Pharmacopeia (USP) Class VI. A non-governmental organization, the USP sets high standards for materials used in food and beverage processing. Class VI compounds meet the tightest requirements for non-toxicity.

  6. Product Material Highlight- Cork & Rubber Gasket

    Leave a Comment

    Rubber cork — a combination of milled cork grain and synthetic rubber — is a specifically formulated material that has been at the forefront of gasket technology since the 1970s. Also referred to as cork rubber, this material is available in many different sizes and variations, and is used in a broad range of applications and industries.

    A combination of first grade granulated cork and rubber polymer such as natural rubber, synthetic rubber, silicone, nitrile, EPDM, or neoprene, rubber cork is held together with glycerin-glue applied under heat and pressure. The resulting formulation, about 70% cork grain and 30% rubber, is highly resilient and compressible with minimal sideways flow, making it an optimal sealing and chemical solution for modern gasket applications.

    Advantages of Rubber Cork

    The individual properties of rubber and cork combine to make a highly resilient formulation for volatile and rigorous environments. Rubber cork provides strong resistance to oil, solvent, and fuel, as well as moderate resistance to fungus, acid, and extreme weather conditions. With the ability to withstand sideways flow, rubber cork is also impact resistant, shock absorbing, and resistant to fluid penetration.

    In addition to the physical and chemical resiliency of this material, other benefits of rubber cork include high compressibility and flexibility (characteristics of cork and rubber, respectively) and a wide range of fluid compatibility. It can be used with or without a pressure sensitive adhesive (PSA) backing, as it is already an anti-slip material. As such, rubber cork also provides acoustic insulation and reduces levels of transmitted vibration.

    Typical Applications and Industries

    Die cut rubber cork sheets are available in a range of sizes, densities, and thicknesses for a variety of applications such as gaskets, spacers, bumpers, protective pads, stripping, electrical transformers and switchgear, and more. The versatility of rubber cork allows it to fulfill specific requirements for many industries including automotive, aviation, railroad, shipping, agriculture, petroleum and electrical.
