Precision terminal when select material, want to consider using performance, not only should also satisfies the requirement of stamping process for processing and subsequent performance.
Basic requirements, precision terminal material selection is as follows: 1, has a good punch forming performance: 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, the material thickness tolerances shall comply with the national standard of mold clearance is suitable for the specified range of the thickness of the material, if material thickness tolerance is too big;
Not only directly affect the quality of the parts, can also lead to waste.
Precision terminal material properties and stamping production very closely, its properties directly affect the quality of stamping process design, stamping parts and products service life, also affect the production efficiency and production cost.
Have punch press equipment: imported from high precision terminal shrapnel stamping precision grade, punching accuracy of plus or minus 0.
01 mm, SPM1500 ran faster.
