About Us

Yijin Hardware has a 20-year history in the fastener industry. Its professionalism, precision and perfect quality system have won the recognition of major companies around the world. Yijin Hardware has engineers who independently develop and design molds, and is capable of carrying out a series of supporting services such as preliminary mold design, proofing, and electroplating based on customer drawings or samples. What is (stainless) fastener machining? Fastener machining is also called cold heading. It is one of the few new non-cutting metal pressure machining technologies that utilize the plastic deformation of metal due to external forces, and uses a mold to redistribute and transfer the metal volume to form the required part or blank. Yijin Hardware has great advantages and experience in parts molding. We provide efficient work support and services for the global precision electronics and watch industry. The cold heading process is most suitable for the production of bolts, screws, nuts as well as standard and non-standard fasteners such as rivets and pins. The equipment commonly used for the cold heading process is a special cold heading machine which is also called a heading machine or a tooth rubbing machine in the industry.
