Stamping, casting is an important means of processing, these two processes can play an important
role in the field of automobile manufacturing, whether it is casting or stamping, for quality auto
body, are the basis of guarantee. That is, stamping parts quality will directly affect the quality of
the car, and therefore must undergo a rigorous inspection and qualified to use.
1 material, stamping parts quality content inspection
Before the production of stamping parts, to a
comprehensive and detailed examination of materials to
ensure their compliance with production conditions, in order to avoid problems continued into the workpiece.
2, mass production of the first stamping the necessity
Because of first stamping quality determines the quality of the entire batch, so checks must not be careless,
mainly observed stampings whether there are defects such as cracking, folding and deformation.
3, online zone checking and extracting of stamping parts production checks
In order to improve the qualification rate of the workpiece, need to zone checking by Visual Tools, but also to
carry out spot checks on all stages of the production of stamping parts, in order to better control the overall quality.
4, punching accuracy testing
Mainly use the tools the stamping full scale accuracy testing, reach larger workpieces to rate changes in advance for
early warning purposes, so as to avoid affecting the dimensional accuracy of products as a whole.
5, stamping out check
This is product manufactured before the last mark, again through outbound checks confirm the quality and accuracy of
stampings to prevent unqualified products into the market, both for the user and manufacturer, is very bad.
