The surface stars of stamping parts produced by hardware processing manufacturers refer to the small protrusions that occur on the surface of large and medium-sized covering parts during stamping production. When checking the appearance quality of stamping parts with a cooking oil stone, the small flash points on the surface can be seen. This subtle flaw can cause scattered and irregular reflection of light after spraying, which can harm the appearance quality.
The surface stars of stamping parts refer to the small protrusions that occur on the surface of large and medium-sized covering parts during stamping production and manufacturing. When checking the appearance quality of stamping parts with a cooking oil stone, the small shining points on the surface can be seen. This subtle flaw can cause scattered and irregular reflection of light after spraying, which can harm the appearance quality.
The key reasons for surface defects caused by hardware manufacturing and stamping are:
① Dirty surface of raw materials caused by unclean surface cleaning or oil cleaning;
② Dirty surface of raw materials caused by improper or long-term storage of raw materials after cleaning and dropping after opening the roll;
③ Poor cleaning of the mold or failure to clean the mold immediately resulting in dirty surface of the mold;
④ The surface of raw materials is dirty before Hot-dip galvanization;
⑤ The damage of the stainless steel layer on the surface of the mold after long-term production and manufacturing, resulting in delayed friction between the mold and the surface of the raw material, and the surface dezincification of the raw material;
⑥ The anti pollution standards of the production line are not very good, and there is dust falling into the surface of raw materials and molds on the production site;
⑦ When carrying out transportation production and manufacturing, when employees wear general anti cutting gloves for work, the debris caused by friction between the general anti cutting gloves and the board falls into the surface of raw materials and molds;
⑧ The cutting powder caused by the process flow of the edge pressing and punching machine enters the mold.
During the stamping production process of large and medium-sized covering parts, the surface stars are generally not fixed and fixed. The problem of surface stars is a difficult problem in stamping production and manufacturing. The most serious condition of surface stars occurring during the production process is that one part has more than 20 stars on its surface, and the maintenance construction time is 10 minutes per piece. Reducing and eliminating surface star problems in stamping production and manufacturing, thereby reducing failure rates and maintenance construction time, is a key regulatory new project in stamping production and manufacturing.
