五金沖壓件與鑄件、鍛件相比，具有薄、勻、輕、強的特點。沖壓可制出其他方法難于制造的帶有加強筋、肋、起伏或翻邊的工件，以提高其剛性。秦皇島五金沖壓件由于采用精密模具，工件精度可達微米級，且重復精度高、規(guī)格一致，可以沖壓出孔窩、凸臺等。冷沖壓件一般不再經(jīng)切削加工，或僅需要少量的切削加工。熱沖壓件精度和表面狀態(tài)低于冷沖壓件，但仍優(yōu)于鑄件、鍛件，切削加工量少。

沖壓件是靠壓力機和模具對板材、帶材、管材和型材等施加外力，使之產(chǎn)生塑性變形或分離，從而獲得所需形狀和尺寸的工件（沖壓件）的成形加工方法。沖壓和鍛造同屬塑性加工（或稱壓力加工），合稱鍛壓。

Stamping is a forming and processing method for workpiece (stamping parts) by applying external force to plate, strip, pipe and profile by press and die to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure machining).

凸模刃口端部修出斜面或弧形。這是減緩沖裁力的有效方法。減緩沖裁力，即可減輕對凹模側(cè)材料的拉伸力，從而達到抑制沖壓件產(chǎn)生翻料、扭曲的效果。

The end of the punch is repaired with a bevel or arc. This  an effective way to slow down the blanking force. By reducing the force of buffer, the tensile force of the side material of the die can be reduced, so that the stamping and twisting effect can be suppressed.
