Steel Stamping Process And It’s Flow

Steel Stamping Process And It’s Flow

Steel Stamping is a process involved in the automotive industry for the productivity improvements and unit cost reduction. Stamping processes to be used for a creating a panel in automotive industry and the panels are depend on its design. However, the process involves various operations such as blanking, drawing, piercing, forming, notching, trimming, hemming, etc. The Steel Stamping process is a single stage operation and with every stroke of the press desired metal products is produced. 

Blanking is a method, which prepares the initial approximate form of the part in flat sheet. Drawing is a method of stamping process generally involved in the first operation to attain depth related form. Piercing, notching, hemming, are the major operations related to product designs. Trimming generally removes the extra material on the periphery of the panel provided for blank holding during draw operation. Decision on trim line is very important and becomes deciding factor to obtain good draw.

Stamping process involved in the automotive industry mainly responsible for processing outer layer parts of a vehicle body such as door, roof etc.  This activity comes under quality information and the quality information is of two type’s namely internal and external quality information flow.  

External Quality Information Flow:

In the external quality information flow, the first link of the four craft industries contact closely with suppliers, the quality department and manufacturing.

The metal sheets that pass the inspection section will be sent to the manufacturing process and the quality departments have a SIP (standard inspection process) confirm stand in the last section in stamping workshop process. This section examines stamping parts before been stored in the warehouse. If quality defects are found, they would determine responsibility area and repair. 

Internal Quality Information Flow: 

In the internal quality information process, stamping workshop contains opening the material, deep drawing, and scrap edge, punching and reshaping processes. The products from stamping workshop need to pass the workshop inspection and confirm with standard inspection process.
