In the manufacturing industry, versatility and speed are the name of the game. Suppliers and manufacturers need to be able to quickly adapt established processes for new applications while delivering consistent quality and service. At the Sur-Seal® Company, we understand the demands on manufacturers and look to be as versatile as we can to help meet our partners’ needs. Because of this, we offer waterjet cutting as part of our capabilities. Here’s a quick introduction to waterjet cutting and the benefits it can provide to manufacturers and suppliers across the industries where we work.

What is waterjet cutting?

Waterjet cutting is a material cutting process that uses a high-pressure stream of water to cut through a variety of materials, rather than using a blade or other instrument. The water can be combined with a type of abrasive to produce an accurate cut with outstanding edge quality.

Benefits of waterjet cutting services

Here are just some of the benefits of using waterjet cutting to convert engineered materials:

  1. Material versatility – Waterjet cutting can be used on both hard and soft materials including rubber, foam, plastic and more.
  2. Multiple thicknesses – The power of the waterjet allows precise cutting for a range of thicknesses, from very thin foils to thicker materials. At Sur-Seal, our CNC waterjet cutting services can cut materials up to 6” thick.
  3. No heat – Because the waterjet cutting process does not involve any heat (otherwise known as a cold-cutting technique), it can be a useful technique for cutting through materials without damaging them.
  4. Tight tolerances – Using a CNC controlled guiding machine, waterjet cutting can maintain extremely tight tolerances for a variety of materials.
  5. Application versatility – Because waterjet cutting is so versatile, it is used by manufacturers and suppliers across industries for a wide range of applications.

Versatile converting capabilities enhance manufacturing efficiency

We believe the more versatile we can be as a converter, the more value and efficiencies we can bring to our partners. That’s why we are so excited about our waterjet cutting services and the capabilities it represents. Our CNC waterjet cutting bed size can range from 72” to 120”, and it is multi-head and multi-layer, making our solution an ideal choice for any number of applications. By combining industry-leading technology with our demonstrated expertise and outstanding service, our converting services can provide exceptional value to manufacturers across industries.

The benefits of precision slitting services

Purchasing log rolls of materials like papers, films, foils and tape can provide manufacturers a cost savings compared to buying smaller, individual rolls. But working with those large log rolls is often impractical and narrower widths are required for efficient application. That’s why the Sur-Seal® Company added precision slitting services to our suite of converting services. To help manufacturers achieve maximum efficiency, we now provide lathe slitting, rewind slitting and laser inspection services. Here’s a quick snapshot of the benefits precision slitting services can bring to manufacturers across industries.

Lathe slitting

Lathe slitting services are best suited for narrow roll widths because the process allows for a more precise cut. Our lathe slitting features a programmable logic controller (PLC), which increases reliability, control and accuracy. We can even have multiple rolls on a common core, letting us work on multiple projects at once. Another benefit of lathe slitting is that it’s a high-speed process that helps manufacturers complete projects quickly and accurately.

Rewind slitting

We offer three different types of cuts via rewind slitting: razor blade, sheet and score cutting. Our auto-edge guide system can sense the edge of a material or part and help align it to the correct position. This helps lower project costs and improve quality. Our rewind slitting can accommodate long length rolls and can work with materials including tapes, films and papers.

Laser inspection

Our laser inspection precision slitting services are accurate within 0.002”. We offer FAI, PPAP and SPC reporting that helps increase the accuracy and consistency of converted products. Another major benefit of laser inspection is speed. With our best-in-class equipment, we can produce results within about 20 seconds.

Precision slitting services enhance manufacturing efficiency

Regardless of the specific process used, precision slitting services help increase the speed, accuracy, consistency and quality of manufacturing projects while also helping to limit costs and material loss. All of these benefits add up to a more efficient manufacturing operation that can help suppliers and manufacturers win more business.

If you’ve been looking for precision slitting services for your next manufacturing project, Sur-Seal is here to help. Contact us today to get started.

How do thermal pads work?

There are a lot of different types of thermal interface materials on the market. However, of all the forms available, thermal pads (aka thermal gap pads) are the best choice for mass production. Let’s break down why that is.

What do thermal pads do?

Thermal pads serve the same purpose as every other form of thermal interface material. That is, they sit between two components and transfer heat from one to the other. This usually means dissipating heat from a heat source to a heat sink, to protect a device from overheating.

Thermal pads accomplish this by being effective gap fillers and efficient conductors. The ability of the pad to fill tiny gaps in the assembly is referred to as wet-out, and softer materials tend to wet-out better than firmer materials. A thermal interface material’s inherent conductivity is measured in Watts per meter-Kelvin (W/mK), and the higher the W/mK number, the better that material is at transferring heat.

Silicone thermal pads

Silicone is a highly versatile and effective material for thermal pads. Silicone can be manufactured to a wide range of thicknesses and compression levels to suit an impressive range of design requirements. Additionally, silicone thermal pads provide beneficial electrical isolation properties.

Graphite thermal pads

Graphite is an excellent choice for designs that require a thin, highly conductive thermal interface material. Designed for demanding performance applications, its thinner structure requires relatively smooth and parallel surfaces in order to achieve wet-out and maximum thermal performance.

Other types of thermal pads

Silicone and graphite are two of the most common form-factors used for thermal pads. However, they’re far from the only choices out there. These alternative choices include:

  • Acrylic
  • Polyester
  • Aluminum
  • Fiberglass

These materials each offer unique benefits and drawbacks. They are often chosen for designs that have particularly niche requirements.

Thermal pads vs. thermal paste/grease

Finally, there’s a long-standing debate about which is better — thermal pads or thermal paste? The truth of the matter is, they both get the job done. Selecting one versus the other comes down to design and manufacturing requirements.

Thermal paste can wet-out extremely well, providing an exceptionally thin bond-line and thus great performance at a very low unit cost. However, it also tends to be messy and difficult to control. Precision equipment is required for consistent application, as application by hand makes precision nearly impossible.

This can be an expensive piece of capital equipment, which also requires ongoing maintenance. Additionally, thermal grease can be subject to long-term performance degradation due to factors such as pump-out, thermal cracking and capillary attraction.

Thermal pads, on the other hand, provide an easy-to-use and scalable option for manufacturing. Pads can be fabricated to precise specifications, allowing for fast and easy placement. While a pad is not as compressible as a paste, the range of available materials means thermal pads are extremely effective with any substrate. Additionally, thermal pads maintain their initial performance over the long-term since they are not subject to the same types of degradation as thermal grease.

Sur-Cool thermal pads

Sur-Seal’s Sur-Cool line of silicone thermal pads are designed for maximum affordability and effectiveness. We understand that time is valuable for the engineers we work with. That’s why we guarantee a fast and clear process, starting with selection and design and continuing all the way through fabrication and delivery.

What is a thermal interface material?

Also known as heat transfer material and sometimes shortened to TIM, a thermal interface material is any substance placed between two components to improve the transfer of heat from one to the other. Usually, the goal is to dissipate the heat by transferring it to a heat sink, which prevents electronics from rising to dangerous temperatures.

What are thermal interface materials made of?

There are a lot of different materials on the market. There are pastes made of various liquid polymers, pads made of wax, aluminum, graphite or silicone, tapes, solders, gels and more. Of all these options, the most common forms are pads and pastes, while the most common base material is silicone.

What to look for in a thermal interface material

To choose the right thermal interface material, you need to know both its inherent thermal conductivity and how it wets out.

Inherent thermal conductivity

Inherent thermal conductivity is defined as Watts per meter-Kelvin (W/mK). It’s a measurement of how much heat a given material can disperse over time. The higher the number, the more heat that material can handle.


Wet-out refers to the ability of a material to replace air gaps in an assembly. It can also be thought of as how soft or squishy the material is. That softness determines how well the material can spread to fill in any spaces that would otherwise be occupied by air (which is a poor thermal conductor).

Other considerations

Besides those two key parameters, there are a few other criteria you can look at when choosing a thermal interface material.

  • Messiness – while thermal paste has excellent wet-out, it can also be difficult to control its application during production. Pads are fabricated for easy placement.
  • Cost – generally speaking, the higher the thermal conductivity of a material, the higher the cost of the material. This is partially dependent upon what types of thermally conductive fillers are used in the material, as some are more expensive than others.
  • Compression – to get a material to optimal wet-out, it needs to be placed under a certain amount of pressure. Softer materials require less pressure to be effective.

How are thermal interface materials used?

Any item or product that’s using electricity is either already using or could be using a thermal interface material. A list of every possible application would rival an old encyclopedia set in word count, but here are just a few examples to get the imagination going:

  • LED arrays
  • Cell phones
  • Hard drives
  • Medical devices
  • Touch screens
  • Digital cameras
  • Vehicle consoles
  • Robotics
  • Home appliances
  • Video game consoles
  • Power tools

What do I do if I need a thermal interface material?

Engineers in need of a thermal interface material should get in touch with a fabricator specializing in thermal management. At Sur-Seal, our experts can help with selecting the right material for any project, regardless of if it’s still in the concept stage or on the verge of mass production. Sur-Seal focuses on making the selection and fabrication process fast, painless and affordable. That’s why we created our Sur-Cool line of silicone thermal pads. We’ve made it simple to find the right solution that’s both high quality and cost effective. Sound too good to be true? We can prove it — just reach out and request a quote.

What is Thermal Tape?

Sur-Cool Thermal Tape is a dual-purpose thermal interface material (TIM), acting as both a TIM and as a mechanical fastener. Sur-Cool’s double-sided thermal tape is made from coating both sides of a fiberglass carrier with a high-performance thermally conductive acrylic adhesive. The result is a cost-effective thermal interface material that provides exceptional bonding strength in a thin format.

What is Thermal Tape Used For?

Thermally conductive tape has many applications where it is used today. Some of the most common applications are as led thermal pads, where the thermal tape is used to mount linear LED strip lights to the troffer heat sinks. In this application, the tape is acting both as a mechanical fastener as well as thermal interface material between the heat source (the LED’s) and the heat sink (the metal troffer).

Is Thermal Tape Electrically Conductive?

Sur-Cool Thermal Tape is not an electrical conductor. Thanks to the fiberglass carrier in the center, the material acts as an electrical insulator.

Thermal Paste Vs Thermal Tape

The pros of Thermal Paste are its low unit cost and strong initial thermal performance. The drawbacks for thermal paste are its messiness and long-term performance degradation.

Thermal tape on the other hand is much easier to handle and work with but is slightly more expensive than thermal paste and will likely not reach the initial performance level of thermal paste. However, it is worth mentioning that thermal tape will maintain its performance in the long-term, Sur-Cool thermal tape’s price is very competitive in comparison to other thermal pads.
