Stamping is one of the most commonly used means of metal processing. Metal stamping parts refer to the molds used for steel or non-ferrous metal plates at room temperature, which are formed into specified shapes by the press to provide the required pressure for processing. So how does the hardware stamping manufacturer examine the quality of hardware stamping parts? Next, KAIXIM Aluminum will share with you.
For metal stamping processing, we must first control the quality of raw materials, inspection period can be divided into the acceptance of materials and materials before cleaning, production inspection and materials after. The following five inspection methods can be used to test the forming stamping parts.
Touch inspection
Wipe the surface of the outer covering with clean gauze. Inspectors are required to wear touch gloves along the stamping parts along the longitudinal pressed against the stamping parts surface touch, this inspection method depends on the inspector's experience. If necessary, the suspicious area can be detected and verified by polishing the oilstone, but this method can be regarded as an effective and rapid test method.
Abrasive polishing
1. Firstly, clean the surface of the outer cover with clean gauze, and then polish it with oil stone. Use relatively small oil stone to polish places with arcs and places hard to reach
2, the choice of particle size depends on the surface condition. Fine grained whetstone is recommended. The polishing direction of the whetstone is basically along the longitudinal direction, and it fits well on the surface of the stamping parts, some special places can also supplement the horizontal polish.
Flexible mesh polishing
Wipe the surface of the outer covering with clean gauze. Any pitting and indentation can be easily found by polishing the surface of the stamping parts along the longitudinal direction with a flexible sand net.
Oil test
Wipe the surface of the outer covering with clean gauze. Use a clean brush to apply oil evenly in the same direction to the entire outer surface of the stamping part. Put the oil coated stamping parts in the strong light inspection, it is recommended to put the stamping parts upright in the body position. By this method, it is easy to find tiny pitting, dimple and ripple on the stamping parts.
Visual inspection
Visual inspection is mainly used to detect the appearance abnormality and macroscopic defects of stamping parts.
The above is KAIXIN Aluminum's sharing on how to inspect the quality of metal stamping parts. After knowing these inspection methods, if we can operate them proficiently, we can detect the quality of the products and do not have to worry about the poor quality products.
