Die-Cutting Methods for Custom Gaskets: Understanding The Pros and Cons

Die-cut gaskets hold the world together. That’s why when you’re designing a custom gasket, you select the elastomers and adhesives with utmost consideration, or the consequences can be costly. Equally important to gasket design is selecting the right machining method to manufacture them, which is why custom gasket manufacturers invest in multiple die-cutting technologies. 

Die cutting and how it impacts cost and quality of your custom gasket 

Depending on your gasket and how they need to perform, each die cutting method has advantages and drawbacks. When choosing the best method, custom gasket manufacturers will weigh things like material properties, project volumes, tolerance requirements and output per volume. They also factor your top priorities, cost or quality. 

If you want to understand how and why your custom converter chooses a specific die cut to fabricate your gasket and its impact on project costs, this comparison guide provides a great starting point. 


Steel Rule Die Cutting

Steel-rule die cutting is by far the most common method for manufacturing gaskets. Like a mechanized cookie cutter, it presses a steel rule die directly into the material to cut the shape.  

Advantages 

  • Cost-efficient for large production runs. 
  • Higher throughput with the ability to nest additional rule within the steel rule to achieve multiple cuts in a single pass. 
  • Consistent clean cuts and smooth edges. 
  • Low upfront costs for custom-shaped dies. 

Consideration 

  • May cause some material displacement. 

Rotary Die Cutting

Custom dies are fitted on a cylindrical anvil and rolled on the flat material to remove shapes and leave perforations in the material.  

Advantages 

  • Exceptional throughput,ideal for high-volume or repeat projects. 
  • Achieves consistently accurate kiss-cuts well as perforations. 
  • Optimal method for producing pressure sensitive adhesive-backed components on a liner. 

Considerations 

  • Greater lead time and expense for sourcing custom-shaped metal dies. 
  • Less cost-efficient for small-volume or single production runs. 

Reciprocating Knife Cutting

A blade guided by a robotic router cuts precise shapes from sheets of foam and other flat materials. 

Advantages 

  • Eliminates the need for custom dies for shorter lead times and no tooling costs. All that’s needed is an updated CAD file.
  • A true multi-purpose tool with the highest variety of cuts at various depths, all within the same production run. Including: kiss-cuts, creasing, milling-routing, punching, engraving and angle cutting.
  • Produces highest yields per inch of material with computer-guided nesting software to get the most cuts that leave the least amount of matrix (waste material).

Considerations 

  • Lower throughput than die methods. 

Waterjet Cutting

Waterjet cutting is another die-less method. It uses a pressurized stream of water from a computer-guided nozzle to cut shapes from flexible material with exceptional precision.

Advantages: 

  • High precision to achieve narrow tolerances and dimensions. 
  • Suitable for small volumes, prototyping and proof of concept. 
  • No hardware costs as it eliminates the need to source custom-metal dies.  
  • Achieves smooth edges, particularly from more challenging material such as foams and rubber that are rigid, thick or dense. 

Considerations 

  • Longer throughput per unit increases production time, which can make large volume runs cost-prohibitive. 

Laser Cutting

A software-guided laser beam focuses heat onto sheet material to make precise cuts. 

Advantages

  • Optimal for jobs with a fast turnaround and prototyping, similar to other dieless methods.  
  • Produces intricate and delicate shapes with high precision, particularly from thin sheets of material. 

Considerations 

  • High temperatures from the laser can leave burns and melted areas along the edging (known as the heat-affected zone), potentially impacting the gasket’s performance and appearance.
  • Not suited for thicker materials, longer cutting times extend the heat-affected zone.  

Our manufacturing expertise, your benefit  

In manufacturing, every cent counts and the die-cutting method chosen by your custom converter will have a big impact on production volume as well as the quality of the product. Both have a large impact on the cost of your custom gasket.

Bridging The Gap: Polyolefin in PSA Tapes is a Game-Changer For Electronic Device Design

There’s no escaping electromagnetic waves. They occur naturally in the air, but they also emit from high-frequency devices. That’s a reality in our connected world. When it comes time to release your electronic device to the market, adequate EMI shielding is essential, otherwise the risk of exposure ranges from disruptive to damaging.

In the worst-case scenario, EMI causes data corruption, surges in voltage, current overload and overheating, any of which can shorten the lifespan of the device. (It’s no wonder hospitals, gas stations and airlines insist we keep our smart phones powered down around expensive equipment.)

EMI shielding tape provides a lightweight multi-purpose solution, as it simultaneously shields and holds components in place. But there’s one unfortunate reality in product design: Some substrates have many beneficial properties for electronic components, but present challenging design hurdles. That’s where engineers and product designers apply problem solving while keeping costs to a minimum.

When innovative new products unlock new solutions for challenging designs, it’s a game changer for OEMs. Recently, 3M introduced its 5113 series of electrically conductive tape, designed to adhere to some of the most challenging-to-bond surfaces while providing enhanced performance in EMI shielding.

Enhanced Ruggedness and Exceptional Sealing: Best Die-Cut Adhesives For Electronics

Can tape make your electronic device safer, more reliable, longer lasting? Die-cutting adhesive tapes is the go-to for securing gaskets, panels, screens, batteries and other components in portable and wearable devices. However, there’s a plethora of tape products made with specially engineered foams, films and adhesives that can also safeguard sensitive components as well as the battery system.

That’s critical because devices get around. Whether you’re talking about laptops, smartwatches, tablets or the latest smartphone, batteries and electronic components demand protection from the hazards of normal use as well as rough handling.

Protective benefits of die-cut adhesive tape in electronics

  • Reliably seal out dust and water.
  • Absorb and cushion against shock, impact and vibration
  • Heat dissipation to prevent overheating.

The need for protection: The future is portable and battery-powered

As our world becomes increasingly electrified, connected and portable, demand will continue to increase for lithium-ion battery systems.

Lithium-ion-powered electronic devices have forecasted 14.5% market growth between 2023 and 2032. Tablets and PCs are driving nearly one-third of global revenues for Li-ion powered electronics. Their leadership position is expected to remain over the coming decade, though smart, wearable devices will also contribute to demand.

Key considerations for die-cut tapes in electronics: Rugged protectiveness

Lithium-ion batteries deliver many sought-after properties in today’s portable devices. They’re lightweight, retain capacity after thousands of charging cycles, fast-charging and have a long lifespan.

To keep lithium-ion batteries safe and operable in electronic devices, two key considerations are top of mind:

  • Thermal runaway: Heat or high impact that damages the highly flammable electrolytes within the battery cell can result in thermal runaway and combustion, setting the table for an explosive situation.
  • Water and oxygen exposure: Lithium-ion batteries also require protection against moisture and oxygen. Cracked housing or total submersion in water can reduce performance and render the battery inoperable.

This gets to another important thing to consider about personal electronics: They’re personal.

Laptops, smart watches and smartphones are in near-constant contact with the end user. They’re worn, stored in pockets and transported in bags and backpacks, within reach 24/7. They’re subject to exposure to varying environmental conditions and temperature changes, accidental drops on hard surfaces and in water, and so on.

These devices demand enhanced protection of the battery against impact, vibration, heat and moisture. Tape selection around some of these protective properties can ensure the longevity and performance of these devices.

Considerations in choosing die-cut tapes for electronics

  • Bonding strength
  • Resistance to environmental conditions
  • Conformity to curved or irregular surfaces
  • Consistent adhesion for the life of the product

At SRP, our longstanding partnerships with top brands like 3M reflect the trust and confidence they have in our ability to represent their brand effectively.

Testing

Testing and prototyping are essential steps in the process, and a converter’s approach should facilitate rather than hinder these stages. Understanding the converter’s prototyping process, machining capabilities, and timelines for producing and shipping samples is vital to ensure a smooth and efficient development process.

Tolerance

Making the right call on the tolerance range of your part is essential to managing your costs. Whenever you die-cut foam and sponge material, some variability in the dimensions is expected between parts. The reason is when the machine cuts into the flexible material, it causes material compression, deflection and concavity. When you’re calculating specifications for soft components, you’ll want to adopt a tolerance range that’s probably wider than what you would normally choose for a hard component. But a skilled custom converter can calculate the optimal tolerance range for your gasket. This results in higher volumes of high-quality parts while minimizing material waste and production time.

Machining

Efficiency is at the core of lean manufacturing practices. Selecting the right machining process for specific materials is key. Different foams and sponges used in gasketing require tailored approaches to achieve the desired outcomes. By designing a production plan centered around efficiency, quality and waste reduction, a custom converter can help you optimize costs without compromising on the final product.

Machining Custom Shapes From Flexible Materials: Exploring Kiss Cutting vs. Die Cutting

In the world of flexible material cutting, the choice between kiss cutting and die cutting can significantly impact the outcome of a project.

In the world of flexible material cutting, the choice between kiss cutting and die cutting can significantly impact the outcome of a project. Tolerance requirements, the efficiency of the method and material considerations all play a pivotal role in determining the most suitable method for machining custom parts from your chosen material.

In the following, we’ll outline the differences between kiss cutting and die cutting, along with some of the core factors that inform which machining method we choose for your part.

Kiss Cutting vs. Die Cutting: What’s the difference?

Die cutting is a term that’s often used to describe machining custom shapes from a material. The most common method uses a sharp steel die to cut shapes from the layers of foil, film, foam and adhesive. Kiss cutting is one of several die-cutting methods, and it’s often used to create a roll or sheet of peel-and-stick gaskets on a release liner.

Die Cutting

  • Die cutting is a term that’s sometimes used interchangeably with through-cuts, which is when the die punctures through all layers of material, and meets the metal anvil.
  • Flatbed die cutting is the most standard and oldest method for cutting identical shapes out of rolls and sheets of foam, tape and other flexible material.
  • Much like a cookie cutter, the sharp-edged die or a steel rule is pressed directly into the material using a hydraulic press until it meets the metal anvil on the other side.
  • After cutting, the part is completely separated from the remaining matrix, or waste material.

Kiss Cutting

  • The counterpart to through-cuts, as the die does not pass through all layers of materials.
  • The die is calibrated to end the cut at the very top layer of material that needs to remain uncut. For most kiss cuts, the uncut material would be the release liner. Once the cut is made, the matrix, or waste material, is cleared away, leaving the shapes on a liner.
  • The most common machine method for kiss cutting is a rotary die press. But kiss cuts can also be achieved with a software-guided laser cutter, where the beam cuts down into the specified depth of the material.

Other considerations when choosing between die cutting and kiss cutting

There’s no one cutting method that suits every job. That’s why we plan production around what achieves the highest quality at the best value to you. Here are just some of the top considerations that factor into the decision of which machining method is best to produce your part.

Tolerance Requirements and Material Considerations

For parts that require a tailor fit with little deviation, flatbed die cutting will achieve the most precise dimensions with sharper edges, as the cuts are performed straight into the material.

Rotary die cuts made with a cylindrical die are less suited for thicker foams and sponge materials, particularly for jobs with narrow tolerance requirements. In these instances, flatbed die cutting can provide an alternative that produces the results you’re looking for. However, for thinner materials, rotary die cutting and laser cutting can yield tight tolerances.

Which Method Is Most Efficient?

Rotary die cutting can produce a higher output in less time than flatbed diet cutting, whether used to make kiss cuts or through cuts. (Rotary die cutting is capable of achieving both.) As the cylindrical die rolls over the material, it’s constantly producing shapes, making it ideal for high-volume jobs.

When used for making kiss cuts, rotary die cutting is a method that also makes assembly more efficient. When the gaskets and other types of adhesive-backed parts are presented on a release liner — whether on a sheet or a roll — the parts are easy to remove, easier to handle and require no sorting.

Flatbed die cutting, on the other hand, is more ideal for through cuts and kiss cutting thicker materials. It offers a rapid changeover, but the machining is slower than the rotary method as the hydraulic press stamps out one shape at a time.

When done well, kiss cutting is highly efficient and keeps material waste to a minimum. However, kiss cutting requires highly skilled machinists and ongoing monitoring for quality control and to make sure the die is achieving those precise cuts. Otherwise, cuts that are too shallow can ruin the parts on the liner.

By understanding these differences and considering the specific needs of each job, it’s important to make informed decisions that lead to the best quality results. With the guidance of experienced converters like SRP, achieving precision and efficiency in shaping flexible materials becomes a reality. Contact us today to discuss your latest project!

Top 5 Considerations For Choosing Adhesive For Custom Gaskets

Adhesives can quite literally be the glue that holds operations together. Whether it’s tape, glue or a spray, adhesives can be found in nearly every industry due to their bonding strength and flexibility for numerous uses.

In the context of gaskets, using adhesives can prolong the life of the gasket and increase the effectiveness of the system as a whole. Recently, we wrote about The Top 5 Considerations For Custom Gasket Materials. Considerations for selecting the right adhesives for these gaskets follow much of the same thought process. Five considerations when choosing adhesives for custom gaskets, and why they matter.

1. Temperature

One of the first considerations to think about in selecting an adhesive for custom gaskets is to establish the temperature range it will be exposed to. There are two different aspects to focus on.

First, it is important to think about both the external and internal temperatures the adhesive will be experiencing on a day-to-day basis. This would include any potential outdoor weather extremes, as well as the internal temperature of what the adhesive, and by extension, the gasket, is keeping in.

Once that has been established, it is time to turn your attention to what type of adhesive you intend to use, and more specifically, what it is made of. There are a number of effective industrial adhesives on the market, but not all of them boast the same temperature tolerances. Selecting an adhesive that is effective for the entire potential temperature range it will be exposed to is crucial for your application.

2. Surface and substrate condition

To select a proper adhesive, considerations need to be made on the different substrates that will be attached to each other.

The first step is to analyze the properties of the substrate that may affect adhesion. Substrates can be rigid, flexible, smooth, coated with a certain chemical or material, and everything in between. These variables can all influence how well the adhesive performs.

Next, it’s important to account for the type of substrate itself. Metals, coppers, foams, polycarbonates, and a host of other materials can all be found in or around a gasket, so picking an adhesive that performs well with the surrounding materials it will encounter is an important aspect.

3. Method of application

Determining exactly how the adhesive will be applied to the custom gasket system can easily narrow down viable adhesive options.

If the adhesive will be applied by hand, there can be roadblocks to certain methods of application. Would it be feasible to use tape? Maybe a spray or glue is more practical? If the adhesive will be applied by an automatic process, maybe there is only a handful of feasible adhesive options during production.

Coming to terms with how the adhesive will be applied can narrow down choices based on practicality and ease of use alone.

4. Environment

Going almost hand-in-hand with temperature considerations when choosing a gasket adhesive are the environmental factors. Some of the most important to be aware of are:

  • Chemical resistance: There is a possibility that the adhesives used in a gasket system could be exposed to the fluids or chemicals that the gasket will be holding in. Are they corrosive or toxic? Certain chemical resistances should be factored in when deciding on a proper adhesive if there is potential for exposure.
  • UV: Consistent exposure to UV rays can easily compromise any exposed adhesives that do not have adequate UV resistance.
  • Moisture: Moisture from either internal or external sources can come in contact with adhesives in a gasket system and could potentially compromise the seal.
  • Function: Will the gasket be static throughout its lifetime? Or will it be exposed to movement and/or vibration? This will be an important factor when selecting a proper adhesive because if movement and vibration are present on a day-to-day basis, specific adhesives will need to be used.

5. Compressional forces

Compression set refers to a gasket’s ability to return to form after being exposed to a high compressional force. This is a crucial variable because, over time, gaskets that are exposed to force and have a minimal ability to return to form (otherwise referred to as a high compression set) can result in gaps or leaks.

The compression set of the gasket can greatly influence the type of adhesive used in the project. If the gasket will be exposed to high compressional forces, the chosen adhesive will need to be able to withstand the constant pressure and release of the system. Improper consideration on this front can result in the use of adhesives that quickly break down and compromise the gasket system.
