Since our company found 2015, we have been committed to high precision induction coils, and make unremitting efforts to create high-quality precision inductor coils. Now we have become the qualified supplier of Huawei, Xiaomi , Apple and other international first-class brands. In this industry, manufacturers are so much in market. And the quality is uneven, many manufacturers competition at a lower price, and the actual product can't satisfied 100% tolerance of customer`s requirement ,which affected customer product performance. Inductor coil manufacturers in the industry are basically using low precision molds, and basically use domestic tension , so a large number of inferior coils flooded the whole market, causing quality problems to customers. Mr. Wang is a engineer from USA ,whom are manufacturing precision instruments. He recently looking for high precision air core coil, because the requirement is very strict. After testing with many samples provided by Chinese suppliers, it failed. Because the coil size deviation is too big, product size and high performance inconsistency . As a result, he do need to detect and select defective products in the production process before put into production, which seriously affects the customer's output schedule. Mr. Wang has tried the coil samples from several manufacturers, but he has been unable to find the air core coil with high precision, size tolerance controlled at 0.1mm and good consistency. Mr. Wang found me through our website, and contacted me with the attitude of trying. Since this product is an special coil, the quality and performance consistency requirements are very high. After our detailed communication, Mr. Wang decided to ask for sample. I promised him to provide samples within a week. After cooperative efforts of various departments of our factory, we successfully sent the sample to Mr. Wang a week later. And there nearly a month of continuous testing and verification, Mr. Wang told me that the test data could completely meet their requirements. Therefore, Mr. Wang decided to place two batches of trial production orders for me to ensure the stability of air core coil size and performance 100% again. After two batches of trial order, he feedback the coil performance was very consistent, and finally decided to treat us as the preferred supplier. Why can our air core coil be recognized by USA customer? 1) 100% of the raw material input is tested for reliability, pinhole, uniformity, meter resistance, impact resistance, pinhole and at least 10 tests that are higher than the industry standard. 2) The equipment is mainly imported from Japan, the automatic winding machine, the dimensional accuracy is 0.001, which may not be possible in the same industry 3) Operating precision welding technology under the microscope, few in the same industry can do it. 4) There are about 10 to 20 product production processes, and each process has 5 quality control parameters. On average, each product has 75 quality control data from semi-finished products to finished products. 5) Adopt full-automatic glue filling technology, vacuum technology, peers use manual glue filling.

The wireless charging coil is to convert the original fixed power supply into the transactional inductive electromagnetic field. And through the characteristics of the wireless conduction of the sympathetic electromagnetic field, reconverted into a current for charging at the receiving end, which will be sympathetic to the electromagnetic field. When the sympathetic electromagnetic field encounters a metal object, an eddy current will be generated inside the metal, and the eddy current will generate heat energy in the metal, causing many problems, such as low charging efficiency of the charging coil and high heat during charging. Chengpin has been hard to study how to improve the charging efficiency of charging coil and ensure the safe use of the product. Chengpin make a lot of test , add charging coil pad in the transmitter and receiver, using functional ingredients lattice electric field electron scattering caused by thermal motion and the interaction between electronic. Absorbing electromagnetic energy can rapidly enhance the inductance value of the inductor coil, reduce the heat of the current, so that the maximum efficiency of electromagnetic energy convert into electric energy. Mr. Oliver works for is a factory specializing in the production of mobile phone chargers. He has been working in this company for more than 10 years as a purchasing manager, who is quite familiar with the company's affairs and can handle various problems easily. Recently, his company plans to develop wireless charging business, and talked with several potential customers, but all the samples sent out to customer have been returned back. The customer said that the product size is too big to sell, the charging speed is slow, and the charger is very hot. It seems the order will be lost, his company are anxious and angry. In order to solve the problem ,they have three meetings per a day and one survey every two days. When Mr. Oliver knew that Chengpin was also developing wireless charging coils, he invited us to participate in the development of wireless charger. After the technical personnel of Chengpin learned about their product, we proposed that the charging coil used in their product was not reasonable in design and the magnetic pas of the wireless charger coil was poor quality. We redesigned the wireless charging coil according to the structure and performance requirements of their charger. After 3 days of trial installation, the charging speed was increased by 10%. The maximum temperature of the charger was only increased by 10℃ for a day and a night of continuous test charging. The new design of wireless charging coil also adjusts the shape with the new shape, making the volume of the product smaller and more beautiful. After the successful development of this case, Mr. Oliver`s company immediately obtained a large number of orders. Chengpin has also become their company's largest supplier of wireless charger coil . How can Chengpin wireless charger coil get recognition of customers? 1) 100% of the raw material input is tested for reliability, pinhole, uniformity, meter resistance, impact resistance, pinhole and at least 10 tests that are higher than the industry standard. 2) The equipment is mainly imported from Japan, the automatic winding machine, the dimensional accuracy is 0.001, which may not be possible in the same industry 3) Operating precision welding technology under the microscope, few in the same industry can do it. 4) There are about 10 to 20 product production processes, and each process has 5 quality control parameters.

Since it established 18 years ago, Jinyang always focused on high precision inductor coil and kept efforts to build high-quality brand in coil field. Now it has become a top qualified supplier such as Huawei, Xiaomi and Apple. Recent years there are so many inductor industry manufacturers with uneven quality. Meanwhile, they competitive at a lower price, but the actual product can`t achieve 100% tolerance with high precision, thus impacting the production performance. Because most of them used the mould with low precision, and basically using the domestic tensioner made so many bad coil in the whole market,caused the quality problem to the customer. Mr Wu who works in a branded car company in Japan, recently purchases the inductor coil for their products badly. Because this kind of coil is very strict with high-tech quality, many samples didn`t pass the test due to they don`t match its tolerance and have the different size & performances. During the production, it makes many rejects to pick up before next step . it delays the process for the customer. Mr.Wu already has tried some samples from several factories,but still not found the exact one can be controlled the size to 0.1mm. On occasion, Mr.Wu found Jinyang on the website, and was attracted by our production with detailed description and display, then contacted us. Since vehicle-driven coil needs very high quality and performance, he decided to ask us to make samples first after communication between us. We promised him to send the required sample within one week. Nearly a month our all colleagues make efforts to produce the samples successfully. One week later we sent the samples to Mr.Wu. When they got the samples, they made many testes and found the test data matched all their request. Mr. Wu was very satisfied with our samples. He decided to place our 2 trial orders in order to get the stable quality. After this, the customer accepted our coil and approved our company as their exclusive supplier. Why can jinyang inductor coil be accepted by famous car customers? 1.Jinyang inductor coil use Japan Auto Coil Winding Machine with repeat precision 0.001, others can`t do this. 2.Jinyang`s winding machine all use the Japan tensioner to ensure the coil size and flatness. There is no one can do it n this field. 3.Jinyan`s coil raw material are from the well-known suppliers, such as Leslie Soler, Japan Big Black, Sumitom. 4.10 years ago, Jinyan can control the precision within 0.05mm, but others only control it between 0.1-02mm 5.With better equipment and stricter quality control, even Jinyang inductor coils stuck in the same place for 5 years , others may not be able to catch up.
