Star Product of Chengpin Technology: EFD20

Chengpin Technology has long been committed to R&D and manufacturing as a high-tech enterprise, and its high-frequency transformer EFD20 has become a star product in the industry. Adopting the operational model of lean production lines, Chengpin Technology is hardly matched by any other peer worldwide.

The EFD20 high-frequency transformer is a representative product of Chengpin Technology. With its outstanding performance and high quality, it has been favored by numerous industries including frequency conversion, bathroom appliances, display, and industrial sectors. Moreover, Chengpin Technology’s high-frequency transformers have solved long-standing troubles for many customers, such as high costs and long lead times.

In the transformer market, Chengpin Technology’s EFD20 high-frequency transformer stands out due to its high productivity, strict inspection standards, full automation, and high technological content. Chengpin Technology attached great importance to product testing and verification in the early stage of R&D, ensuring product quality through tests and certifications by authoritative third-party institutions.

Strict control over raw material quality, coupled with advanced production processes such as 100% fully automated winding and assembly lines, enables Chengpin Technology’s high-frequency transformers to not only meet or exceed industry standards in performance but also satisfy customers’ demands for high quality and high productivity.

Recently, Mr. Zeng from MG, a well-known enterprise in Shenzhen, approached Chengpin Technology, seeking a high-frequency transformer to replace Donggang Electronics’ EFD20. Amidst fierce market competition, Chengpin Technology successfully became MG’s designated supplier.

Based on previous successful application cases, we recommended the EFD20 high-frequency transformer for testing and verification. After one month of testing, the customer confirmed that two core technical parameters—high voltage resistance and magnetic shielding—of our product are superior to those of Donggang’s EFD20. Having verified that Chengpin Technology’s EFD20 high-frequency transformer meets their requirements, the customer has started bulk deliveries.

With its outstanding performance and high quality, Chengpin Technology’s EFD20 high-frequency transformer has not only won customers’ recognition and trust but also established an excellent reputation in the market. We will continue to uphold the philosophy of "Quality First, Customer Foremost" to provide customers with better products and services.
