Phosphor copper terminals basic requirement for material selection

by:Fortuna     2021-02-09
Phosphor copper terminals material properties and stamping production very closely, phosphorus copper terminals material properties directly affect the quality of stamping process design, stamping parts and products service life, also affect the production efficiency and production cost. The selected phosphor copper terminal materials, want to consider using performance, not only should also satisfies the requirement of stamping process for processing and subsequent performance. Therefore, phosphorus copper terminals material choose basic requirements as follows; 1, has the good stamping formability for molding process, such as bending, convex hull, materials should have good punch forming property, namely, should have good resistance to rupture and setting, otherwise the product easy to produce, such as deformation and rupture caused by the difficulty of repairing mold. For the separation process, insist on material has a certain plastic. 2, with high surface quality of the material surface should be bright and clean level off, without defect. Good surface quality materials, not easy broken when molding, not easy to scratch the mold, the surface quality of parts. 3, material thickness tolerance should comply with the national standards for certain mold clearance applies only to a certain thickness range of the material, if material thickness tolerance is too big; Not only directly affect the quality of the parts, can also lead to waste. In the calibration curve, processes such as plastic, likely due to the thickness deviation is too large and cause the damage of the die or punch.
