Coin Tapping Goes Objective With Wichitech’s Digital Tap Hammer

Wear and tear or distress of construction material needs to be carefully catalogued so that parts can be replaced in time and the integrity of structures maintained. From buildings to airplanes, from concrete to composite alloys, tapping has for long been one of the most popular methods of detecting potential breach of strength.

It is simple to execute, it is affordable and it provides supervisors and engineers with a fair bit of information about hidden weaknesses in the materials being tapped. However the process is subjective to say the least. Operators must gauge the type and the extent of the delimitation simply by the tonal quality of the sound that emanates from the sample when it is repeatedly hit with a hammer. Even though this leaves no visible signs of depredation the frequency of the vibration produced is quite telling.

Ambient conditions, the presence of interference and outside noise can cloud the judgment of the supervisor. This is the reason why sometimes expensive recourses like echo ultrasonics, shearography and thermography have to be used, especially when it comes to judging vulnerabilities in composite materials.

Wichitech Industries Inc. has pioneered a breakthrough in this field that can eliminate the need of relying on the skill-set of the ‘tapper’ for an accurate readout. This is the introduction of objectivity into hammer or coin tapping with the Rapid Damage Detection Device (RD3).


The RD3 is not only light weight and robust, it is also portable. Constructed from the best-in-class components it has a hammer with an accelerometer connected to a liquid crystal display equipped module via a flexible cable.

It proves to be especially useful where detecting delamination is concerned. It supplements the discernment of the tapper with a quantitative numeric read out. Each value corresponds to a pre-defined damage scale and with this kind of standardization, it is easy to entrust the task of probing chinks and signs of stress to operators who aren’t as experienced as their traditional tapping peers.

For any enterprise interested in the maintenance of its composite material structures, this non-destructive probing and examination technique with its new found accuracy is bound to be a boon.

Wichitech Industries Inc. is proud to be the brain behind this offering and looks to changing the face of the NDI industry for the better.

Hot Bonders

As industries rapidly grow in size and mature in terms of the techniques and technological breakthroughs leveraged, there is a growing need of a vigilant and fool-proof repair system to ensure the integrity of complex structures.

It is not enough to detect wear and tear and breakage in time. The adhesives, bonders or resins used to initiate composite and metal bond repairs must be:

  • Sturdy so that they can function properly in extreme climates
  • Portable so that they can be carried into the tightest corners and smallest spaces without any issues
  • Flexible – they should have multiple heat application tips and the ability to connect with other repair units to co-ordinate the temperature of curing for large and sprawling projects

The new-age hot bonders embody all these desirable characteristics. They prove to be invaluable for traditional bonding or repair assignments, secondary bonding processes that generally rely on ovens or autoclaves to proceed without hitches and for research and development projects where prototypes may need to be frequently assembled and dismantled and thus run the risk of compromise.

Bonders epitomize convenience and they have radically transformed the way delicate and precise repair work is conducted for commercial and technical endeavors.


Laying claim to the prestigious epithet of the world’s hottest hot bonders, Wichitech’s line of HB1 and HB2 Composite units are fully manufactured in the US and at as little as 35 pounds they stand for light weight efficiency.

All components of the units are shock mounted in rugged, impact resistant cases that hold themselves well under extenuating circumstances. They come with easy to manipulate settings and a clear display to expedite curing and the exacting task of setting the right temperature for the bonding to be invulnerable.


hotbonderThis fully featured unit is economical to say the least. It packs the punch of larger, more expensive set-ups and comes with multiple thermocouples, a fail-safe mechanism of triggering an alarm if conditions are not conducive to repair work and even a vacuum line and heat blanket to ensure complete lack of moisture and ambient temperature fluctuations which interfere with the sealing process.



One evolutionary step above the H1 units, the HB2 bonders possess all the differentiators that set its predecessor apart with a few key add-ons.

They have two independently programmed heating zones of 20A each to perform cures at different temperatures. A list of pre-programmed options in the menu obviates the need of expertise to use the unit optimally. Compact yet extremely powerful it renders everything from Kevlar to carbon to fiberglass pliant.

Wichitech Industries Inc. lives by the tenets of simplicity, affordability and quality. Its bonders have an impeccable reputation in the market and represent the best of the advancements made in this field.

The Importance of a STEM Education

In the aftermath of one of the greatest economic slowdowns since the Great Depression, it may come to many as a big surprise that there have been and still are many positions available to job-seekers out there. The problem is that these jobs have remained unfilled due to a lack of qualified candidates. Many higher-paying positions, which belie the common wisdom of a “jobless recovery”, are indeed awaiting these qualified candidates. But with a decided lack of properly educated workers, the nation’s employers are having a difficult time finding the right people for the job.

The kinds of skills necessary for the new economic landscape are generally acquired via a solid education in what is known as “STEM,” which is an acronym for Science, Technology, Engineering, and Math. It is a decided lack of competence in these subject areas that is the reason behind many of the vacant jobs in America today. Unfortunately, the prospect of this situation improving over the near term is highly unlikely. Over the next few years (and perhaps longer) we will be faced with a crisis of potentially epic proportions if action on a national level is not undertaken.

Technology is now a given in almost every aspect one’s daily living and the workplace is certainly no exception. Being knowledgeable and competent in the area of STEM knowledge and skills has grown greatly in importance for an unexpectedly wide range of workers and professionals, many of whom, once upon a time, would have barely needed a high school education to be hired.

Properly educating students in STEM subjects prepares them for modern life, no matter the profession to which they aspire. Instruction in STEM helps them to learn how to think critically and to overcome challenges that are often encountered in the modern, high tech workplace.

An example of a company that utilizes such better-educated workers is WichiTech Industries, a leader in the design and manufacture of simple, safe and reliable composite repair systems. With WichiTech’s high quality construction and extraordinary attention to detail, its customers are assured of unmatched performance and value. WichiTech’s composite repair products are found throughout the military and commercial sectors with a loyal and growing customer base ranging from large sophisticated operations to smaller repair shops.

DoD Extending Its Small Business Mentoring Program

A 10 year extension program was requested by the Defense Department to help improve the socioeconomically disadvantaged small businesses and strive for defense contracts.

According to Robert Stewart in his DoD News interview, this program began in 1991 and is known as the Small Business Mentor- Protege Program. This aims to nurture small businesses and cultivate technology transfer between the industry and the Defense Department.

The program is in existence for almost 25 years, but still considered as pilot. Moreover, it has to be reauthorized every few years under the National Defense Authorization Act. Through the intermittent reauthorization, Stewart said that this leaves an impression that the program is only temporary. Most likely, it has a chilling effect, especially when the reauthorization schedule approaches.

The request for extension program seeks to provide stability, save department money, and reassure industry.

Participating on the program requires small enterprises to become prime contractors through selecting one out of the 50 participating larger companies. The selection process ensures alignment on the strategic goals of the two companies to make it successful.

The mentoring and training of the larger companies to the small business lasts no longer than three years. After that, the larger company receives credit from the small business goals. For instance the mentoring is provided by a small business development center, procurement technical assistance, black university or colleges and they get the credit four times the actual enterprise participation levels.

After the completion of the agreement, the small business graduate gets the title of a DoD contract’s prime contractor.

Stewart also elaborated their goals of focusing on the criteria, evaluation, and factors to boost the DoD enterprise contracting demands to benefit from the Mentor-Protege. This serves as a conduit to reach the goals of subcontracting small businesses.

Developing a defense acquisition regulation will help in accomplishing these goals, Stewart said.

U.S. Manufacturing on the Rise

After experiencing the great recession, the United States economy is now rising. The US manufacturing is starting to rise through the annual contribution of American factories, which summed up to around $2 trillion. This information was delivered Jay Timmons, National Association of Manufacturers (NAM) President to the Economic Club of Minnesota on his visit to Washington D.C. The Economic Club of Minnesota includes Cargill, Apogee, 3M Co., Ecolab, and Donaldson Co.

According to Timmons, Minnesota is the home of the most noticeable, robust and resilient manufactures nationwide.

With this, Minnesota factories are now reviving from the trip during the Great Recession despite some restrictions including crippling government regulations, trade policies, backed-up railways and ports, and collapsing roads. Fortunately, after terminating staffs and employees during the Great Recession, they are now hiring new people and give one in every state job.

With 88,000 workers and staffs all over the 70 countries, these manufacturers have 3 million global reach. Timmons commended several companies like Bloomington-based Apogee, manufacturer of architectural glass, and Graco, foam-spraying equipment and machine manufacturer for its expertise and great performances.

Similarly, Douglas Baker, Ecolab CEO, identify NAM as a “champion” in promoting U.S Manufacturers. Moreover, he recognized Timmons as “one of the top shakers and movers” in Washington D.C. Timmons was also credited for becoming persistent on promoting manufacturers on Capitol Hill.

In an interview, Timmons said that he is dedicated in sharing the industry’s challenges and success with the members worldwide. Aside from Minneapolis, he plans to visit 12 more countries on the next three weeks. These prospect countries include Texas, Alabama, Colorado, Washington state cities, Detroit, and Cleveland.

Besides his continuous success and accomplishments, Timmons also disclosed the fact that manufacturing sectors are facing significant challenges and changes. With this, he pleaded to factory heads to minimize broader trade policies, burdensome regulations. Instead, build and improve railways, ports and roads, and submit legislation with long-term U.S manufacturers financing options.


Experts, economists and analysts all over the world are eyeing the latest developments in the US economy with an abundance of positive expectations. After the market crash and the subsequent ravages of the recession, 2014 proved to be a turning point of sorts, encouraging manufacturing to create a stronghold within the country as the trend of outsourcing slowed down considerably. In the race to recovery, Maryland has emerged as a prominent player.

The 42nd largest state in the country, it is a hub of manufacturing and has a clutch of thriving industries to contribute significantly to the betterment of the standard of living of its blue collar workers.


Maryland is one of the only 10 states in the US to retain its ‘AAA’ bond rating from all the major credit rating agencies. In 2013 its GDP was $342.4 billion because of its diversified economy and international trade flow. Both established companies and small business owners or start-ups have made the most of the excellent credit track-record as well as the highly educated population to attract investments and erect ventures with solid foundations. Maryland also plays a crucial role in transportation throughout eastern United States and proudly claims manufacturing to be the engine driving its prosperity and growth.


The nature of manufacturing in Maryland is rapidly evolving. As technology makes vast inroads, the integrated process of production together with the rising savvy of the workers is poised to usher in an era of accelerated growth.

According to a recently published survey, manufacturing as a revenue sector employs more than 100,000 people and adds $20 billion dollars annually to the state GDP.

Some of the reasons behind this excellent performance are:

  • The desirable infrastructure of the state conducive to setting up of manufacturing units.
  • Robust education system that focuses on both theoretical knowledge and practical applications. This fine blend has produced some of the most skilled floor workers and white collar management executives in the country. The ‘skill’ gap may be an issue plaguing other states but the workforce is actually an asset to Maryland’s manufacturing saga.
  • Strategic position as the Boston-Atlanta Corridor on the Atlantic seaboard with borders along Washington D.C. Transportation costs is a major criterion affecting the decision to set up manufacturing strongholds. Maryland also scores big in this regard.


Maryland manufacturing enthusiasts should know that manufacturing accounts for roughly 5.81% of the net Gross Domestic Product of the state and employs 3.95% of the total workforce.

The best thing about the statistics from the government endeavour Advanced Manufacturing Survey is the clear indication of the affluent lifestyle enjoyed by these workers who boast an annual income of $80,310 on an average.

Maryland truly is the ‘land of opportunities’.

The following is a snapshot of the top manufacturing industries in the state and their individual contributions to the cumulative GDP.

An Overview of the Out of Autoclave Process

Out-of-autoclave (OOA) manufacturing has come a long way to process the next-generation structures, particularly in the aerospace industry. The reason for manufacturers to adopt the OOA is due to the two important factors – money and size of the part. Traditional autoclave curing systems are expensive to buy and operate and are available only in limited sizes.

Manufacturers in aerospace and other industries are increasingly turning to OOA to cure parts. Out-of-autoclave is less capital-intensive and less costly, especially as parts increase in size and number. Several of the latest advancements push the technology even further, offering curing solutions that are out-of-autoclave and out-of-the-oven. Among the solutions under development are integral liquid heating/cooling and induction heating. These technologies offer the same benefits of OOA and then some – fewer steps, less material and shorter cycle times.

OOA is most heavily utilized by aerospace industry manufacturers as well as a variety of sectors are adopting OOA methods, from renewable energy to automotive and consumer electronics. This is mainly done to improve the quality of the products, increase throughput, cut down on production time, decrease capital, operating and labor costs. Curing time appears to be industries biggest bottle neck and this has forced companies to send employees to trade shows in search of new OOA processes. With the advancement in the OOA technology, some companies are using induction heating to create aerospace parts and internal car parts.

OOA is evolving to address the application problems ranging from part size, manufacturing costs, part quality and curing time. It also is adapting across sectors, including aerospace, automotive, renewable energy, consumer electronics and even farm equipment.

The Power of Wind

Manufacturing composite repair systems for clients in a range of industries, from aerospace to alternative energy, we are constantly staying on top of the latest news, information, and technology as they relate to our clients.

One of the ever-expanding sectors that are attracting a lot of buzz these days is wind energy. In many areas of the world, use of this alternative energy is growing significantly, and in Northern Ireland, 2013 saw the highest levels of wind energy ever for that region. In fact, on December 17, 2013, 506MW of electricity were generated, which happened to be 36% of all electricity needs for Northern Ireland at the time, as well as the first time wind generated over 500MW for Northern Ireland. *

This was a cause for excitement at a recent Northern Ireland Renewables Industry Group (NIRIG) conference, where the focus was not only on this past success, but on promoting future success. One of the reasons for this focus on wind energy is that Northern Ireland’s aging electricity grid, built in the 1960s, was not designed with wind in mind, making it a challenge for many to take advantage of.

This area’s infrastructure, and many similar areas around the world, need much better infrastructures to meet greater needs and to attract large investors who could support these needs. The industry and area experts are certain that many opportunities exist for great investment in wind energy, which would in turn bring great benefits. Those involved believe the best ways to do this are through educating the public on the economic advantages of renewable energy, and getting politicians involved.

Of course, Northern Ireland isn’t the only area where wind energy usage is increasing, and where proponents are singing its praises. A surprising study by Stanford University has even shown that “mammoth offshore wind farms can tame hurricanes rather than be destroyed by them.”** The Natural Resources Defense Council (NRDC) credits wind power with everything from job creation to generating enough electricity to power over 11 million homes in a single year.***

Its use is growing and its advantages are being seen more and more; it will be interesting to see what the future holds.




Student Training Kits

At WichiTech, we offer student training kits, which provide power and vacuum for four repair training stations. We have three different types of student training kits:

  1. Kits with vacuum inputs and RD-3 tap hammer,
  2. Kits with only vacuum inputs, and
  3. Kits without vacuum inputs.

Each kit allows you to operate four different training repair stations off of one bonder. In other words, instead of purchasing four separate bonders, you’re able to operate four stations using the kit, which will save you money.

With the student training kit, each student will have his or her own blanket and will be able to program off of one bonder. We offer training in training composites, and we sell these kits to technical colleges and universities. We have separate training institutions that buy them in training composites and any kind of private training institution. When training in composite repairs, you use a bonder and apply the heat to the repair. Ordinarily, you would use one bonder per repair, but now, training institutions can buy only one bonder that can operate up to four stations as opposed to just one.

The alternative way to do this would be to purchase four bonders, since they are necessary to perform certain repairs. Normally, when this equipment is manufactured, it’s manufactured in an oven, which, of course, is a very large appliance, and then these pieces are all assembled. When they’re repaired, you can stick an aircraft back in an oven, and all you have to do is what we call a “spot repair” to the aircraft.

We’ve received a lot of positive feedback from technical schools about our student training kits. Schools are very budget conscious, and lately with the advent of using more composites on aircrafts and even things like cars that are starting to use composites, more people will need to be trained to repair these materials. With the right training, a sheet metal mechanic will be able to do composite repairs. Having those combined skills of sheet metal work and composite training will be valuable in the years to come.

8 Steps for a Better Process Change

When performing an operational process change, it’s important to not only be efficient during the job but also to fully understand what the problem is and what needs to be changed. Here are eight innovative steps to take that will allow you to properly make a process change the best way possible:

1. Understand the Current Process

It’s important that you ask yourself, “Why is the process in its current state?” From there, you can determine what changes need to be made and avoid making previous mistakes.

2. Know the Reason for the Process Change

Usually, the reason for a process change is cost or variation reduction. For a cost reduction change, good cost organization is essential. For variation reduction, the change agent should know whether random variation or special-cause variation can be eliminated.

3. Identify the Specific Change to be Made

Once the flaws in the current process are pointed out to be changed, the new process should be conveyed in a clear and concise way. This can be done in the form of a text document, flow chart or any other organizationally appropriate documentation. It should be easy enough to understand for other operators to know how the new process will work.

4. Make All Affected Stakeholders Aware of the Change

The new process should be expressed to everyone who will be affected by the change. This can be done through a meeting, posting online and allowing anonymous feedback, etc.

5. Validate Process Data and Measuring Systems

Before beginning the actual process change, it’s important to ensure that the data and measures are reliable and to constantly check them to ensure accuracy or any changes along the way.

6. Train for the Change

After everyone has been informed of the impending process change, all operators working on it must be fully trained prior to beginning the actual project.

7. Set a Clear Line

The clear line indicates a point in time in which you will be able to categorize data before and after the change. Once the line is set, you’ll be able to keep track of the change more easily.

8. Measure, Analyze, Improve and Control

After the change has been applied, the results should be properly analyzed and measured in order to control the process.

By conducting these steps, the process change can run much more smoothly and allow everyone involved to be on the same page.
