eTOMMENS was founded in 2015, Etommens team keep to Innovation, diligence, never give up,  let our brand grow up fast,  more and more people recognize Etommens's products.With the reputation of the Etommens gradually, it is often asked what the specific meaning of the company named the Etommens.Here, I will tell you the story behind Etommens, maybe you will have a deeper understanding of the meaning of Etommens after reading it.

The story began in 2004, when China just joined the World Trade Organization, actively participated in the global division of labor, officially to the world factory road stride forward.At that time, the domestic instrument industry was still in its infancy.Domestic technology generally has shortcomings, enterprises do not have independent research and development of technical support, direct introduction or copying of technology is the mainstream practice of enterprises, but also the fastest way to produce benefits.Especially high-end instruments, most of them rely heavily on imports.Both technology and market are mastered by foreign enterprises, the whole instrument industry is strangled by foreign countries, and the dividends of high-end industry are basically divided by foreign enterprises.The whole environment has not yet realized the importance of having independent scientific research ability.

The whole environment is so, but some people wake up a little earlier than others.In order to reverse the foreign monopoly of technology, one university in Dongguan has a group of teachers who specialize in the research and development of instruments.Some teachers apply for longitudinal research projects at municipal and provincial levels;Some teachers actively cooperate with enterprises to research and develop projects together.They are all contributing to the technology research and development of the instrument industry.

Among them, a professor in the Department of Electronics is the most active. From 2004 to 2015, the professor and his team started the technology research and development by applying for the national project fund, and basically completed the prototype production of the oscilloscope, signal generator, LCR measuring instrument, multimeter, power supply and other multifunctional electronic measuring instrument, and successfully passed the technical evaluation. And completed the preliminary accumulation of theory and technology.At the stage of combining research and development with production, the professor contacted several enterprises and organized several groups of personnel for further research and development.However, the project faced many challenges such as heavy workload, large investment and unclear market positioning, and the final research and development results could not be converted into products.

At that time, as a member of the team, I personally experienced the difficult process of research and development.Having achieved some results with such difficulty, I did not want to waste my previous achievements, so I resolutely decided to take over the torch from the professor and continue to conduct in-depth research in order to expand the research results.I found two college students who had not yet graduated, and formed a research and development team of three to continue to tackle the problem and climb to a higher and more difficult summit.The number of people is not enough, we simplify, give up the original multifunctional technical route, from the multifunctional electronic measuring instrument project to choose a most interested direction - power supply, research and development.The research and development goal is also the simplest part to start from the market the most easily embedded universal 30V5A to tackle.This is not easy for a small team to start up. Because they do not copy the technical route on the market and insist on independent innovation, the process from zero to one is difficult, perhaps the peers have deep experience.With the gradual development of the company, the Etommens has also absorbed a large class of students who are interested in instrumentation and aiming to improve China's instrumentation technology. Under the leadership of the teacher, they realize their own value.

At this point, you may have guessed the meaning of "eTOMMENS".eTOMMENS, meaning the same teacher teaching.eTOMMENS originated from the inheritance between a small team of three and a professor, which is the inheritance between teachers and students.In English eTOMMENS, e stands for electron, and eTOMMENS stands for Etommens. When combined together, it means eTOMMENS electron.The three doors spread from large to small in the logo of the same gate graphic represent the small team of three at the beginning of the same gate.At the same time, it also contains the meaning of the inheritance of students of different grades, teachers guiding students, brothers guiding brothers, and constantly developing and growing.

On May 26, 2015, Dongguan eTOMMENS Electronic Technology Co., Ltd. was registered in Songshan Lake High-tech Zone.With the government's determination to build Songshan Lake Park into a science and technology benchmarking park, we also have the vision of becoming the most popular enterprise in the industry, and officially start our entrepreneurial journey in this vibrant place.At the end of 2016, from the beginning of the project to the prototype, it took more than a year to repeatedly polished e-TM305, which was officially launched. With its unique appearance, power display, preset power, dual-frequency environmental protection technology and other innovative design concepts, it stunned the market and caused a great sensation when it was launched.

Although the eTOMMENS to eTM-305 successful amazing market as a start, but the development process is still one twists and turns, suffered three big blows.The original team of eTOMMENS is a technology research and development team, so technology is the core competitiveness, but the business experience is insufficient.Business has always been adhering to the principle of honesty, mutual benefit and mutual benefit, and later this simple feelings have been used for many times, the setbacks also come from this.

At the beginning, the eTOMMENS to recruit the first salesman, every day from the company to take goods out of the electronic market to sell, but has been a variety of reasons to evade, received payment to the company.At that time, we were still very immature in business. We believed that he would hand over the payment to the company without any precautions. Unexpectedly, half a year later, the salesman ran away with the money.This was a great blow to the start-up company, and the new fellow almost died in infancy.

After the salesman left, due to the lack of business ability of talent, can only choose to face the difficulties.I personally took students to run the business, every day with students to the electronic market drill, a thick skin to ask the store to try our products.It is the Etommens has no brand awareness, can have an agent willing to sell is not easy.Finally in Shenzhen Baoan an electronic city to find an agent willing to sell the eTOMMENS products, ecstatic, immediately sent two batches of goods in the past to let its sales.The next month to find him for payment, but he caught us did not write the delivery note, did not let him sign the receipt and other reasons, repeatedly with a variety of excuses, do not want to pay.Once again we were cheated and once again we paid the price for our immaturity.

In 2017, due to the innovation of the products launched by the eTOMMENS we gradually showed the competitiveness of the products and gradually gained more and more recognition from the market.With the increase of the market share of the Etommens in the industry, it also caused the attention of the peers.There is a competitor in Shenzhen, in order to stifle the development of eTOMMENS, on QQ, wechat, Taobao, Jingdong and other online platforms for eTOMMENS to publish false information, wantonly smear Etommens.In this process, eTOMMENS argue, it is inevitable to be questioned, eTOMMENS brand image damaged.

After enduring three setbacks, eTOMMENS has become more and more mature.For so many years, it has maintained high growth.On December 11, 2017, the company passed the national high-tech enterprise identification, while maintaining the annual launch of about 100 models of new products, which are well received by the market.In 2019, the monthly sales volume has exceeded 10,000 units.In order to adapt to the ever-developing market demand, Etommens's business scale is also expanding.On January 16, 2019, eTOMMENS set up a branch in Daling Mountain, Dongguan: Dongguan Tombesi Electronic Technology Co., LTD., which is specialized for eTOMMENS production supporting facilities;At the end of 2019, the novel coronavirus epidemic occurred.In order to help China's fight against COVID-19, Express has launched a full series of ultrasonic simulators for mask machines and upgraded a full series of automatic frequency tracking ultrasonic digital machines.At the same time, Dongguan eTOMMENS Ultrasonic Technology Co., Ltd. Etommens branch has been established, specializing in the study of various applications in the field of ultrasound.With the rapid development of eTOMMENS, continue to expand new business, the establishment of Dongguan Xuechang Topu Electronic Technology Co., LTD......

Now eTOMMENS is developing in the direction of collectivized companies.In the process of innovation and entrepreneurship of the eTOMMENS, there are sweat, tears and moved.Fortunately, living in the land of China, gave us can thrive in the soil;I am very happy to have the opportunity to work hard together with fellow teachers and brothers to realize my life value!

How far the eTOMMENS will go, we cannot predict.However, we always stay true to our original intention, insist on making creative products and conscientious products, and strive to become the most popular enterprise of power electronics in China, which is also the mission of Etommens!Bless China, bless eTOMMENS!
