A mascara tube is a small cylindrical container that holds mascara. It typically has a screw-on cap and a wand applicator attached to the cap. The tube is designed to hold the mascara formula and keep it from drying out. The wand applicator is used to apply the mascara to the eyelashes, allowing for lengthening, volumizing, and defining effects. Mascara Container.Mascara tubes come in various sizes and shapes, and are usually made of plastic or glass. They are a common beauty product found in most makeup collections.Mascara Bottle Mascara Tube,Empty Mascara Tube,Mascara Bottle,Mascara Container Kunshan Muchun Electric Co., LTD , https://www.nbmuchunelectric.com
It is this product that has concocted a lot of hard work, and now it has finally blossomed.
Industrialization difficulties
Compressors correspond to the lungs of electromechanical products, and the US Navy believes that single-screw compressors are the most suitable lungs for nuclear submarines. This product has been included in the list of technical blockades in China by Western countries.
Breaking through the foreign technology blockade is the dream of several generations of scientific researchers in China. In the mid-1980s, an ordinary engineer carried the technical results of a single-screw compressor that he had studied for many years and began to bust its industrialization. He was very good at investigating. In order to find funds, Zha Shiliang sought many companies to seek help. The beginning was to go to some state-owned enterprises, but they encountered disillusionment and distrust. Checking Liangliang went to find some private companies, but private companies also have concerns that this project is too big. If you fail to accomplish your job, you will not necessarily belong to yourself. In desperation, Chanchaoliang thought of cooperating with foreign companies. Investing hundreds of thousands of US dollars to engage in such a major project is not a big deal for wealthy foreign companies. Although Cha Liangliang will encounter smiles every time he enters the door, but after waiting for a long time, he is always without any information. After finding a person to inquire, every foreign company will find a foreign consulting agency to evaluate it before the cooperation. The result of the assessment is the project’s The benefits are very good, but the Chinese can't do it.
In order to make funds, Charlie has spent 10 years. In 1997, Zha Shiliang found the Duanzhou Compressor Research Institute in Zhaoqing City, Guangdong Province. The Zhaozhou Duanzhou Compressor Research Institute invested 4 million yuan, which is only enough for the single-screw compressor to verify the cost, the verification is over, the capital is gone, and the single-screw compressor still cannot realize industrialization. But he was not discouraged. On the one hand, he continued to look for funds. On the other hand, he immersed himself in scientific research and improved the performance of single-screw compressors.
Finally, in 2000, Zhaoqing Duanzhou Compressor Research Institute cooperated with Shunde and established Shunde Zhengli Precision Machinery Co., Ltd. of Guangdong Province. Based on the original research and development achievements, Zhengli Company has developed the second generation of single screw compressor products using its own new technology. In 2000, it successfully obtained the support of the Ministry of Science and Technology's SME Innovation Fund. The new product has innovated the structure of the screw and star wheel, and applied for a number of domestic and foreign invention patents. It is known as the "longevity and energy-saving single screw compressor" and has formed an annual capacity of 3,000 sets.
Reputation becomes louder
The single-screw compressor produced by Zhengli Precision Machinery Co., Ltd. went public. Since it was a new product of the emerging companies, it did not cause a big sensation at the beginning of the listing. A chance to let people have a new understanding of this emerging company's new products.
The thing is this: Guangdong Mei Group's Welling Electric Co., Ltd. and Hyundai Group's Jinke Electric Co., Ltd. have all purchased single-screw compressors from Zhengli Precision Machinery Co., Ltd., but the two companies only use Zhengli’s products as spares. The United States, Germany's compressor as the main power equipment. It happened that the two foreign machines, one had burned the bearings, one had burned the motor, and had to use the standby machine of Zhengli. This time, like breaking up the jars and smelling the wine, the two companies found that the company's machinery is so good, with low noise, large gas volume, low failure rate, energy saving, and even better than foreign products.
After the incident spread, the company's reputation gradually shouted. A Japanese-funded company in Zhaoqing intended to purchase a foreign compressor. After seeing the company's products, it immediately changed its mind and decided to use domestically-made equipment. Zhengli Company began to change the situation that China’s medium and high-grade compressors depend on imports.
Second business
Today, Zhengli has a domestic and even world-leading single-screw compressor technology. This technology has obvious advantages in energy saving and has obtained a number of patents from Chinese, English, American, French and other countries. However, Zhengli Company also faces many difficulties. In order to produce more expensive and cheaper products, there is an urgent need to develop a single-screw processing machine with higher accuracy and efficiency. The research and development work needs huge funds to back up, and Zhengli Company has limited strength. In management, there are various bottlenecks encountered after the development of most small-scale enterprises to a certain scale.
At this time, Midea Group is actively investigating the general machinery industry in order to expand its new business. After careful investigation and in-depth analysis of the air compressor industry, it decided to merge and acquire Guangdong Zhengli Company to enter the industry with a high starting point and high efficiency. After half a year of negotiations and negotiations, an agreement was reached. On November 28, 2007, Midea Mechanical & Electrical Equipment Group officially took over the management and management rights of Guangdong Zhengli Company.
Since the US's entry into power, Zhengli has shown a good momentum of development through the adjustment and integration of organizations, personnel, systems, and market resources in the past half year. It is expected that it will increase by about 20% in 2008.
At the 4th China International Fluid Machinery Exhibition in 2008, Zhengli Company focused on recommending oil-free water-lubricated single-screw compressors to the industry. After 5 years of development, this product is a high-end product in the field of air compressors. The monopoly of foreign brands in this field. Zhengli's patented high-precision meshing pair breaks the water's low viscosity and low sealability, ensuring that the compressor's volumetric efficiency reaches a higher level. Taking the OGWFD22 model as an example, the exhaust pressure is 0.7MPa, the displacement is 3.5m3/min, and the motor power is only 21.88kW, which is better than other famous foreign brands, but the selling price is 10% lower than that of foreign products with the same specifications. 15%.
Zheng Li's case shows that technological innovation can only release its maximum energy when combined with strong capital and advanced management.
Leveraging on the production capacity of the US-based Zhengli oil-free single-screw compressor
"Oil-water-lubricated single-screw compressors to be mass-produced will stand at the commanding height of similar products in the world." At the 4th China International Fluid Machinery Exhibition in 2008, Chief Engineer of Guangdong Zhengli Precision Machinery Co., Ltd. Pointing to a new generation of single-screw compressors that attracted many visitors told China Industry News.
