Die Cut Gaskets 101

Posted by Kate Gluck on Dec 17, 2018 8:58:01 AM

Often one of the last parts considered when designing a product, gaskets fulfill important functions in an array of machines, medical devices, automobile engines and even household appliances. These essential components are employed to resist various media, temperature, pressure levels, and more in order to prevent leakage, protect against dust and other environmental contaminants, inhibit vibration frequencies, or ensure part integrity. Despite their importance, gaskets rarely command the attention they deserve. Understanding the most common properties, materials and capabilities of these essential, though often unseen components, helps manufacturers design the best gasket for an application.

Graphite Gaskets for Thermal Management

Posted by Mark Swanson on Jun 20, 2018 8:05:08 AM

Graphite gaskets are die cut from thermal interface materials (TIMs) with strong thermal conductivity. Graphite also resists thermal shock, damage that occurs with rapid changes in temperature. Across planar surfaces like printed circuit boards (PCBs), graphite dissipates heat evenly and rapidly. Graphite’s mechanical properties increase with temperature, but die cut graphite gaskets resist cold, too. 

Graphite is flexible and can be produced without fillers or binders that impart rigidity. Flexible graphite gaskets are die cut from expanded sheets or foil-core materials in a range of thicknesses. Thin, lightweight TIMs made of graphite sheets are ideal for heat spreading applications where space is limited. Graphite gaskets also support the use of pressure-sensitive adhesives (PSAs) for ease-of-installation. 

By understanding how graphite sheets are supplied, die cut, and used, engineers can determine whether this TIM is the right choice for thermal management. Let’s take a closer look.

Thermal Interface Materials: Graphite Gaskets

Posted by Mark Swanson on Apr 4, 2018 2:35:06 PM

Thermal interface materials (TIMs) are used in computers, lighting, power electronics, and other systems that generate excess heat. They create a thermal path from a heat-generating component to a heat sink, an active or passive device that dissipates heat. In products such as cell phones, LED lights, and automotive batteries, heat that’s not discharged properly can reduce service life. In some cases, excess heat can even cause component failure. 

Engineers who need thermal management solutions have a variety of TIMs to choose from. Unlike thermal greases, die cut products aren’t messy and will conform to surface irregularities. They don’t require expensive dispensing equipment or time-consuming cleanups either. Examples of these die cut products include thermal tape, thermal pads, phase-change materials, gap filler pads, and heat spreaders. Die cut thermal interface materials also include graphite gaskets that provide numerous advantages.

Die Cut Flange Gaskets: Applications and Industries

Posted by Mark Swanson on Feb 13, 2018 12:54:17 PM

Die cut flange gaskets seal the joints in pumps and piping systems. They’re made of compressed non-asbestos (CNA) materials that support precision die cutting for tight tolerances. In the process industry, die cut flange gaskets may need to resist high temperatures, high pressures, or corrosive chemicals. Applications include chemical processing, food and beverage seals, oil and gas, and pumps.

JBC Technologies serves each of these markets and understands their specific requirements. We also provide design assistance and can help you select the right gasket material. In this blog entry, we’ll examine what you need to consider when specifying die cut flange gaskets for your application.

Die Cut Flange Gaskets: Material Suppliers and Trade Names

Posted by Mark Swanson on Feb 6, 2018 10:49:50 AM

Die cut flange gaskets seal the small gaps between flanges, projections at the ends of pipes that add strength and support attachment. Depending on the application, these die cut products may need to resist high temperatures, high pressures, or corrosive chemicals. The process industry wants to work with a die cutter who can meet tight tolerances, but engineers may also need help evaluating gasket materials.

JBC Technologies is a precision die cutter with valued-added solutions such as engineering support. We source flange gasketing materials from Thermoseal and Garlock, trusted partners in our strategic supplier network. When you ask JBC for die cut gaskets, we can provide advice about material selection. Plus, we use automated, flat-bed presses to convert sheeted materials cost-effectively. 

Let’s examine some of the flange gasket products that JBC can source, convert, and die cut for you.
