Packing & Delivery
Packing Details : Packaging individual packing and standard export carton. Delivery Details : reach most of the countries within 3 to 10 business days.
Shock bubble film: The inner wall of each carton is cushioned with anti-impact foam to ensure that the product will not be damaged due to transportation
Suitable carton size: We will choose the right size box according to the weight of the product. Too Much Weight / too little weight per case is not good for product protection and freight savings for customers.
Box packing requirements: In order to avoid damage to the boxes in transit, each box has packing tape. Cases shipped by sea have waterproof film on the outside.Marks should be pasted according to clients’s requirement.
Company Profile
Dongguan Feirui Electronics Co., Ltd. is located in Donguan City, which is known as"the World's Factory"in China. We are engaged in developing and producing engine parts including starting controllers, speed control units, automatic voltage regulators (AVR), synchronizers, load share modules, and other correlative generator accessories, such as chargers, sensors, actuators and other related products. We have emulational system which is the most advanced in the same industry. The system can imitate the whole process of real generator. Therefore, we can control our quality with the precise testing equipment. On the other hand, we own some generator experts with rich experience in electromechanical automatic control system. Being good at soft ware & hard ware, these experts are trained by some well-known diesel engine factories. With about 10 years' experience and skill, we can supply the best technology support service. According to customers' requirements, we can develop some special products and supply OEM service. Due to our unremitting efforts for many years, we have set up wholesalers in Nigeria, Egypt, Thailand and Philippines. Following the ideal of"Quality First, Credit and Service is Our Belief", we strive for innovation to make satisfied generator parts. We expect to create more achievement tomorrow and welcome you to contact us for cooperation.
PCBA Automatic Optical Inspection Equipment:
ALD-620 type automatic optical inspection equipment, referred to as AOI, is based on the principles of optics, image comparison theory, statistical modeling principles of smart devices to detect welding defects on common problems encountered. AOI technology to detect the most representative of the three functions: fault, leakage, anti.
1. After the solder paste printing: printing process can be found in the defect, which will produce bad because the solder paste printing welding defects to a minimum.
2. reflow ago: most defects can be found from the solder paste printing and placement of the machine. 3. Reflow: bad ownership process can be detected at this stage, so there is no defect flows final customer.

Sealing machine

In order to improve production efficiency, the company adopts advanced glue injection machine, and the glue surface of products sprayed by the machine is more beautiful and even.

In addition, it perfectly solves the problem that the glue is not easy to dry in rainy weather, reduces the waiting time of customers, and can meet the urgent order needs of customers.
Simulation Test Platform:
Quality Department simulation test platform, Simulate and test the electrical functions of the electronic products in the operation of the generator, whether there are effective, reliable and stable performance
Goods Final Test Room:
It simulating generator load works for 12 hours continuely,to test products' Electrical Property if reliable and stable , after continuous work in high temperature. (According to Aging Test of electronic components probable failure course of various reasons,unqualified items and early-failures will be filtered).
Our company takes part in Shanghai power exhibition every year. This well-known professional exhibition enables us to establish a happy relationship with customers from all over the world. Our products are exported to 30 countries and areas such as Southeast Asia, the Middle East and Africa, highly recommended by domestic and foreign customers.


In the picture, Our customers are very interested in our remote monitoring system. No matter anywhere in the world, as long as
there is the network, you can use mobile phones or computers to monitor the operation data of the generator set, control and
manage the generator set remotely. In addition to monitoring the basic information of the unit, it can also monitor the excitation
voltage, the output voltage of the electric regulation, the bearing temperature, the winding temperature, etc.

LIXiSE controllers

Customers highly appraise the company's advanced technology research and development ability, perfect production process and
advanced testing equipment. More importantly, the products are simple to operate and have complete functions, which attract
customers to place orders and purchase on site.
