Gasket Manufacturing

Mercer Gasket & Shim is an industry-leading manufacturer of precision gaskets tailored for various operations and environments. Our engineers provide personalized guidance and recommendations throughout the gasket fabrication process, from concept development and material selection to large-scale production runs. Here, we provide an overview of our gasket manufacturing capabilities, the gasket types and materials we offer, and the many industries we serve.

Gasket Manufacturing Capabilities

By precisely filling the space between two mating surfaces, gaskets provide the essential function of inhibiting leaks in fluid handling systems. For most applications, the gasket’s profile, shape, and size must be carefully customized to ensure dimensional compatibility with the mating surfaces. Achieving this level of accuracy requires specialized tools and equipment chosen according to the gasket design parameters.

Mercer Gasket & Shim continually invests in the latest manufacturing equipment and fabrication techniques, giving us the flexibility to meet an expansive range of unique customer requests. Our gasket manufacturing capabilities include:

CNC waterjet cutting

CNC waterjet cutting is a computer-controlled process that uses a high-pressure stream of water to cut through everything from soft rubber and foam to hard metal alloys. Our waterjet cutting services are fast, flexible, and precise, allowing us to fabricate simple and complex gasket designs within tight tolerance requirements while minimizing production costs.

CNC laser cutting

Using a computer-guided laser beam, the CNC laser cutting process precisely cuts materials to create custom patterns and features in accordance with a digital design. Our dual-axis CNC flying optic laser cutters allow us to cut materials quickly and cost-effectively with extreme accuracy. This process is ideal for producing gaskets that require high-quality surface finishes and smooth, precise edges.

CNC knife cutting

With CNC knife cutting, the knife is guided along a digitally programmed pathway to cut through elastomers, foam, composites, and polymer materials. Our 120″ by 60″ worktable allows us to cut large parts quickly and affordably.

Die cutting

The die cutting process uses a steel rule die to cut plastics, rubber, sheet metal, and other low-strength materials into specific shapes. This process is ideal when producing gaskets with unusual sizes or shapes.

Vulcanizing

Vulcanization is a hardening process that uses heat, pressure, and adhesives to create a vulcanized rubber seal between two mating surfaces. In addition to providing a higher level of leak protection, vulcanized rubber gaskets are considerably more resistant to oxidation and solvents compared with traditional rubber gaskets.

Bonding

Depending on the requirements of the application, we use hot splicing, vulcanization, and other bonding methods to securely attach gaskets to a substrate.

Types of Gaskets

Gasket designs have increased in diversity and complexity to meet various technical requirements, environmental challenges, and industry standards. To better understand the different designs available and their intended uses, gaskets are often classified according to material, function, or application.

Material

The material used to fabricate a gasket will determine its ability to withstand degradation or damage in the application’s environment. Given the critical role gaskets play in preventing leaks and minimizing contamination, it is important to choose a material that will ensure long-lasting, reliable functionality in the specific application.

Most gasket materials are selected based on their resistance to the chemicals, temperatures, and pressures that will be encountered during operation. For example, metal gaskets are often preferred for high-temperature, high-pressure environments, while elastomeric gaskets are generally better suited for corrosive environments.

Function

In addition to choosing the right material, it is important to make sure the gasket’s design is optimized to perform the specific task required by the application. Gaskets provide a range of essential functions, from creating a pressure-tight and leak-proof barrier to protecting moving parts against excessive wear. Specific examples include:

  • Fluid sealing. The most common function of a gasket is to prevent fluid leaks or fluid contamination in process systems.
  • Environmental sealing. Gaskets can also be used to guard sensitive equipment against the ingress of dust and other contaminants.
  • Anti-vibration. Gaskets are often used in HVAC systems, industrial machinery, and other vibration-generating equipment to dampen excess vibration. This helps reduce wasted energy while decreasing wear on the equipment’s components.

Application

Gaskets may also get classified according to the types of applications they support. Examples include:

  • Transformer gaskets. Transformer gaskets are designed to prevent fluid leaks in gas-filled or water-cooled electrical transformers. They can also be used as environmental seals to enhance the ingress protection (IP) rating of the transformer’s compartments.
  • Boiler gaskets. Boiler gaskets are specifically designed to withstand the extreme temperatures and pressures encountered in boiler systems. Their high tensile strength and great compressibility allow them to protect against dangerous hot water, steam, or exhaust gas leaks.
  • Heat exchanger gaskets. Heat exchangers often require specialized metal-jacketed or camprofile gasket designs that can conform to surface imperfections while tolerating high temperatures and excessive movement.
