Air plasmas versus Surfx’s atmospheric pressure argon plasma – Do you want cheap gas, or high yield?


Air plasmas boast low operating costs because they use compressed air. However, to operate this way, they must employ a blown arc, or dielectric barrier discharge (DBD). In both cases, non-uniform sparks shoot out of the discharge nozzle, which may result in non-uniform treatment of your parts. These plasmas operate with high voltage power supplies, up to 24,000 V. The high voltage is required to breakdown the air. Consequently, the plasma sources must be operated with robots away from personnel to eliminate the risk of electric shock. The blown arcs yield faster treatment speeds then DBDs due to the high degree of gas ionization in the arc. Yet this means the gas is much hotter, and can thermally damage or even melt the part.

Surfx offers atmospheric pressure argon plasmas that are driven with low-voltage, radio frequency power supplies. There is no risk of electric shock. The plasma beam is uniform, and provides the fastest and highest level of surface activation achievable. Surfx’s plasmas are cold so that there is no risk of thermal damage to the most sensitive polymers, such as high-density polyethylene (HDPE) and polypropylene (PP). Furthermore, unlike blown arcs, the plasma sources operate for long periods of time without needing to replace expensive electrodes.

Now I know our competitors are going to tell you that the argon is really expensive and not worth the trouble. This is simply not true. One of our minibeam plasma sources suitable for treating the same parts as open-air plasmas runs on 10 liters per minute of argon. Assuming one runs the Surfx argon plasma 24 hours per day, 350 days per year, the annual cost will be $8,365 USD (for bulk liquid argon purchased in the United States). In China where bulk argon is a lot cheaper, the annual cost will be $3,024 USD.

Using the Surfx argon plasma, a typical part made of molded plastic, glass or metal can be activated for adhesion in 5 to 20 seconds. At 10 seconds per part, one machine can treat about 3 million parts per year. In this case, the gas cost per part is 0.0028 USD in the USA and 0.001 USD in China.

You have got to ask yourself what is more important, having 100% product yield, or saving a few tenths of a cent per part?

Great show at SAMPE Long Beach 2016


Two very well attended talks were given by Misha Grigoriev of sister company, Aerospace Materials Processing LLC. Presented great data on bonding of nutplates and bismaleimide (BMI) CFRP composites using Surfx plasma and even better results will be shown at CAMX in Anaheim. Click here for the abstract and you can email/call me for a full version. Misha also talked about Out-of-Autoclave manufacturing using epoxy prepregs.

Silicone Adhesion – Improving Adhesion and Material Performance


Our new Silicone Adhesion Page focuses on PDMA and the performance benefits of plasma surface preparation.

PDMS is a preferred material in medical device manufacturing because of its stability and biocompatibility. Let us show you how Surfx plasma treatment rapidly increases the surface energy of PDMS, enabling coating and bonding of your components.

Automotive Parts Suppliers – Beware of air plasmas that deliver barely acceptable results



High-density polyethylene (HDPE) and polypropylene (PP) are widely used to produce molded plastic parts for the automotive industry. Obtaining strong, durable adhesion of the electronic components to these plastics can be a big challenge. Surface activation with in-line atmospheric plasmas solves this problem. However, you have to use the right plasma for the job.

Air plasmas that generate hot reactive gases do a poor job of activating thermally sensitive materials, such as PE and PP. Surfx’s cold argon plasmas achieve excellent adhesion with no chance for thermal damage.

Obviously, plasmas that use air are going to be cheaper than those that use bottled argon and oxygen. However, the difference is at most a few pennies ($0.01 USD) on a part that sells for more than ten dollars. Is this savings really worth the risk of a recall down the road? The adhered components must survive tens of thousands of hours of use under constant shaking, temperatures ranging from -10 oC to over 40 oC, and up to 100% humidity. Lab testing cannot duplicate this environment.

Beware of air plasmas that deliver barely acceptable results. Show your customers that you are willing to go the extra mile for a reliable product that never fails during the vehicle’s lifetime.

Hand plasma tools for improving adhesion on plastics


Hand Plasma System for Surface PerperationAdhesion is a big problem in manufacturing goods out of plastic components. Whether one is gluing, printing, or coating these materials, the surface must be clean and activated for adhesion. A safe, cost effective, and “green” way to clean and activate plastics for adhesion is atmospheric pressure plasmas. The plasma generates a stream of reactive gas that removes organic contamination and creates reactive functional groups for bonding. This process occurs in seconds.

Manufacturing costs must be kept to a minimum in order to maximize profits. A big question is how does one go about treating plastic components with plasma in a cost effective way. Should the process be automated, or can it be done more cheaply by hand? The answer lies in the level of production. If thousands of parts must be activated and bonded each day, then an automated system may be justified. However, if production is less than a thousand parts per day, then a hand plasma tool is the right choice.

A fully automated plasma system can cost upwards of $1.0 million USD, when you consider the robotics, the integration, and the entire work cell needed to keep workers safe from the robot motion. A complete hand plasma tool can be purchased for a fraction of this cost. Here is an estimate of the capital required for treating 500 parts per day, 300 days per year: $1.33 per part for the robotic system compared to $0.07 per part for the hand plasma tool.Hand Plasma System for Surface Perperation

Surfx’s hand plasma tools treat plastic parts in seconds, are safe and easy to use, and have minimal EH&S concerns. Our products can save you a lot of money over alternative atmospheric plasmas that must be mounted on fixtures and kept away from the operator.
