Frequency converters have become an essential part of many industries, not just limited to injection molding machines. Their widespread use today is the result of years of development and perseverance. A saying that has always stayed with inverter engineers is, “One minute on stage, ten years behind the scenes.†This reflects the long journey that led to the current success of the industry. While the market for inverters is now vast and full of opportunities, few know the challenges it faced before reaching this point.
Understanding the story behind the inverter's growth is important. It’s not just about the technology, but also about the struggles, lessons learned, and progress made over time. Let’s take a closer look at the key stages of its development:
First, domestic companies began to rise. As large customers realized that foreign brands were no longer the only option, they started paying more attention to local manufacturers. This shift accelerated the localization process and gave domestic enterprises a chance to grow.
Second, foreign brands once dominated the market. In the 1990s, high-voltage inverters imported into China were mainly used in major projects. At that time, domestic users weren’t fully aware of the energy-saving benefits, and these products were sold at high prices without much competition.
Third, as domestic companies discovered the potential in the high-voltage inverter market, they sought technological breakthroughs. However, they faced two major obstacles: customer distrust and product instability. Even though their prices were significantly lower than foreign brands, performance issues kept them from winning major contracts.
Fourth, things began to change. After years of research and development, domestic companies improved their technology to meet customer needs. Reliability became a key factor, and brand recognition grew. Additionally, foreign brands often lagged behind in after-sales service, giving domestic companies a significant advantage. Companies like Dehuafu emerged as leaders in the market, proving that homegrown innovation could compete globally.
After understanding the journey of the inverter industry, one thing becomes clear: when standing on the stage of success, we must never forget the efforts and support that brought us there. This lesson applies not only to people but also to the machinery industry. Success is built on hard work, persistence, and the ability to learn from past challenges.
