Hardware stampings boast advantages such as light weight, thin gauge, and high stiffness; their dimensional tolerances are guaranteed by the tooling, so they typically require no further machining before use. The processes and equipment for stamping are continually advancing: in addition to conventional methods that employ presses and steel dies to produce stamped parts, a variety of specialized forming techniques—such as hydroforming, spin forming, superplastic forming, explosive forming, electrohydraulic forming, and electromagnetic forming—are also rapidly developing, thereby elevating the technological level of stamping to a new height.

The production of metal stamping parts involves a wealth of specific knowledge and technical details, which must be studied, understood, and mastered to gain a comprehensive and thorough understanding of the stamping process. This enables effective practical application, ensuring the production of high-quality stamped parts with excellent performance in service.
Currently, the production process for hardware stamping parts can be broadly divided into four stages:
1. Reasonably and accurately determine the deformation compensation for stamping parts based on the materials used and the product’s structural design.
2. Based on the confirmed compensation amount, proceed with the design of the relevant molds, followed by stamping to produce semi-finished or finished parts. Hardware stamping parts. 3. Process the semi-finished parts according to process requirements to obtain the final finished parts.
4. Further processing is carried out on stamped semi-finished or finished parts, primarily to inspect for defects or undesirable phenomena such as wrinkling, tearing, and cracking. In addition, the uniformity of part thickness and the quality of the forming results are assessed. Any issues identified should be promptly addressed and resolved.
In addition, with regard to tapping and thread machining in the production of hardware stampings, the main aspects involved are internal threads and external threads. For internal threads, the process typically includes drilling the bottom hole and subsequent threading; the diameter of the bottom hole is determined primarily based on the thread specification. For external threads, operations such as thread turning with a threading tool or die threading are performed. Furthermore, during this process, attention should be paid to specific issues, such as inconsistent dimensions and failure to pass thread-gauge inspection.
