Stamping terminal basic requirement for material selection
Terminal material selects the basic requirements in selected stamping terminal materials, not only want to consider using performance, should also meet the requirements of stamping process for processing and subsequent performance.
Therefore, stamping terminal material selection basic requirements are 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 of the parts are of good quality.
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.
Terminal material properties and stamping production very closely, stamping terminal material properties directly affect the quality of stamping process design, stamping parts and products service life, also affect the production efficiency and production cost.
Precision stamping terminal select high-quality materials, from the source to ensure product safety, long service life, with the domestic and foreign well-known brands of raw materials manufacturers (
Such as, ore, Wieland, etc. )
, die steel,
Hitachi, big equivalent)
And powder metallurgy factory establish good interactive relationship, ensure the authentic sex shrapnel terminal materials.
Can provide its core is tasted stamping parts with quality assurance.
Such as product of the elastic life of shrapnel, shell surface salt fog test, terminal testing safety indexes such as environmental protection, etc. )
