五金冲压件与铸件、锻件相比，具有薄、匀、轻、强的特点。冲压可制出其他方法难于制造的带有加强筋、肋、起伏或翻边的工件，以提高其刚性。秦皇岛五金冲压件由于采用精密模具，工件精度可达微米级，且重复精度高、规格一致，可以冲压出孔窝、凸台等。冷冲压件一般不再经切削加工，或仅需要少量的切削加工。热冲压件精度和表面状态低于冷冲压件，但仍优于铸件、锻件，切削加工量少。
手锯加工方法
扁钢的锯削：在扁钢锯口处划一周圈线，分别从宽面的两端锯下，两锯缝将要结接时，轻轻敲击使之断裂分离。这样锯削，而且能较好地防止锯齿崩缺。反之若从窄面下锯，非但不经济，而且只有很少的锯齿与工件接触，工件越薄，锯齿越容易被工件的棱边钩住而折断。
Processing method of hand saw
Sawing of flat steel: a circular line at the cutting edge of flat steel, which is cut down from the two sides of the wide surface. When the two saws will be tied, it will be gently tapped and broken apart. The sawing efficiency is high, and the sawtooth collapse is prevented. On the , if it is sawed under the narrow face, it is not economical, and only a few teeth are touched with the workpiece. The thinner the workpiece is, the more easily the sawtooth is caught and broken by the edges and edges of the workpiece.
五金冲压模具的安装是否正确合理，不仅影响五金冲压件的产品质量和精度，还会影响模具的工作寿命及生产安全。并且熟练掌握冲压模具的安装也是每个冲压工应该掌握的技巧。
Whether the installation of the metal stamping die is correct and reasonable, not only affects the quality and precision of the metal stamping parts, but also affects the working life and production safety of the die. And skilled in stamping die installation is also a skill that every stamping worker should master.
