Late last month, we received a package from a customer in Turkey. Inside this package is the new product Audi 7E0121205J that the customer is eager to develop. He said there was a lot of demand for the product, but he spoke to many suppliers and got feedback that they didn't develop it. So he bought the original product and sent it to us, hoping we could develop it. For this model, our factory will take the way of pre-sale, customers who confirm the order before the product is launched will enjoy our most preferential price.

Our whole staff actively cooperated with the quality management certification staff and re-certified the IATF 16949 quality management certification system on August 15, 2021. Tongchi has always been strict in controlling the quality requirements of our products and has been recognized by our customers and the industry. But we will continue to provide the best quality products to our customers without pride and arrogance.

This month our company invested a lot of money to buy brand new production equipment to produce better auto radiator fans. Why do we invest a lot of money to update our production equipment? 1. Overly old equipment requires regular maintenance and overhaul, and the entire process and system needs to be shut down, which is thought to reduce production, lower production and raise costs. 2. The scrapping of products, in addition to the possible loss of materials, the most direct loss is the loss of equipment efficiency, scrapped products occupied by the use of equipment is meaningless, not only equivalent to equipment waiting in downtime, but also cause equipment wear and energy waste. In the production system, we should pay attention to the efficiency of the equipment, the equipment is the enterprise's minting machine, we should do everything possible to make the minting machine make more coins, make good money instead of bad money.

From May 9 to May 11, 2021, our company will participate in the Auto Parts Exhibition in Shenyang International Exhibition Center. Our booth is located at T83 in Hall E3. At that time, our company will bring the latest developed products to the exhibition, welcome new and old customers to visit.

For more than 20 years, we have been developing the latest products to meet the needs of the market. This time, through the joint efforts of all our engineers and staff, we have developed the new energy car engine radiator fan - Tesla Model 3 and Model Y. The technical difficulties of the new energy radiator cooling fans are: low power consumption, narrow operating temperature range, high temperature control accuracy (±2°C) and high integration with the vehicle thermal management system. The engineers of our aftermarket electric radiator fan factory are working on these technical difficulties and are making breakthroughs in the following areas: optimizing the structure of the brushless motor; optimizing the pneumatic structure of the fan; optimizing the PWM control system; and improving the communication protocol. If you are interested in our new auto aftermarket radiator cooling fan assembly, please contact our sales staff, who will be at your service at any time!
