Company history

In 1973

Established JING DUEN Industrial Co., Ltd., with a factory space of approximately 10-12 square meters. The primary focus of the company was the manufacturing of handcrafted jewelry components.

In 1976

JING DUEN Industrial Co., Ltd. was renamed to YIH FENG Industrial Co., Ltd. The primary manufacturing products shifted to forged bicycle components, with 70% of production focused on iron products and 30% on aluminum products.

In 1982

After obtaining the company license, YIH FENG Industrial Co., Ltd. officially changed its name to YIH FENG Metal Industrial Co., Ltd. At that time, the factory space was approximately 300-350 square meters, and the company had a workforce of 25-30 employees. The main production focus was on forging bicycle components.

In 1989

We implemented measures to enhance research and development efficiency by investing heavily in the acquisition of Mastercam 3D software for program design and CNC comprehensive cutting machines. These investments were aimed at improving the precision and quality of our products.

In 1991

We obtained the X-ray operation license organized by the Atomic Energy Council of the Executive Yuan. This license enables us to utilize X-ray technology to ensure the quality stability of our aluminum castings during production.

In 1992

We established a Quality Control Center Laboratory and introduced various testing equipment, including universal testing machines, fatigue testing machines, torque testing machines, microcomputer hardness testing machines, and more. These testing machines were implemented to ensure the production of safe and reliable product components.

In 1998

We achieved a breakthrough in research and development by successfully forging and producing finished products for computer CPU heat sink backplates. This innovation has caused a sensation in the electronics industry, leading many companies to approach us for cooperation and procurement discussions.

In 1999

To elevate our quality standards, we officially implemented the ISO-9002 international certification on February 1st. In October, we successfully obtained the ISO9002 quality assurance certificate, further solidifying our commitment to quality assurance.

In 2000

Renowned brands in the electronic technology industry, such as Foxconn Technology Group, Delta Electronics, MiTAC , and IBM, have placed consecutive orders with us. This demonstrates the trust and confidence these leading companies have in our capabilities and product offerings.

In 2002

(1) In order to provide superior quality, we have introduced a high-precision coordinate measuring machine.
(2) In March, we strengthened our research and development efforts to shorten the design cycle. We purchased the 3D-CATIA CAD/CAM software, which enables us to perform stress analysis, dynamic simulations, and parameter design for newly developed products.
(3) To enhance our quality standards, we officially implemented ISO9001 (2000 edition) in May and obtained certification in November of this year.
(4) Certified qualifications: ISO-9002 (1994 edition), ISO-9001 (2010 edition), and ISO/TS 16949 (forging) in 2010.

In 2008

To meet the high-precision and high-quality machining requirements of our customers, we have established a CNC department. We have invested in the latest CNC machining equipment and technologies to provide our customers with enhanced quality and delivery. This initiative allows us to deliver superior products that meet or exceed customer expectations.

In 2010

We have ventured into the automotive industry, manufacturing and producing for renowned brands in Europe and the United States. This expansion has allowed us to leverage our expertise and capabilities to meet the stringent quality and performance standards of the automotive sector. We are proud to contribute to the production of vehicles for these well-established brands.

In 2012

We have received orders from major electric vehicle manufacturers in the United States and successfully produced aluminum die-cast battery enclosures and battery covers for them. Our deliveries and quality have garnered positive feedback from our customers, demonstrating our commitment to meeting their expectations and providing excellent products for the electric vehicle industry.

In 2015

(1) We have upgraded our high-precision measuring instrument, CMM (Coordinate Measuring Machine), to meet the increasing demand for higher quality and precision in our products. This investment allows us to ensure that our products meet the strictest quality standards and deliver superior performance to our customers.
(2) To enhance our casting system design and analysis capabilities, we have implemented CAST-DESIGNER, a software based on Upfront Design & Analysis Technology. This advanced software enables us to perform mold flow analysis and optimize the design of our casting systems, ensuring the highest quality and efficiency in our manufacturing processes.

In 2022

We have successfully obtained ISO 9001:2015 certification, which demonstrates our commitment to maintaining and continually improving our quality management system. This internationally recognized standard ensures that our processes and procedures meet the highest quality standards and that we consistently deliver products and services that meet or exceed customer expectations.
