How to cause the poor surface quality of metal stamping parts? There are many reasons for the surface quality problems of stamping parts, such as the surface quality of coils, plates and dies, which will affect the quality of stamping products. The operation in the stamping process and the clamping and unloading of working position instruments may also damage the surface quality of the parts. Therefore, it should be sufficient in every link of the whole manufacturing process Consider the details, try to avoid quality problems that affect the appearance of the product.

The advantages of hardware stamping parts processing are high production rate, simple operation, easy to realize mechanization and automation

As like as two peas, 1, metal stamping die support, because the size and shape accuracy of metal stamping parts, generally do not damage the surface quality of metal stamping die, and the use time is long. So the quality of metal stamping is not chaotic, and the interchangeability is good, and has the same characteristics.

2. Metal stamping processing of large size, complex shape parts, such as small clock stopwatch, car side rail, covering parts, plus the cold deformation hardening effect of metal stamping materials, punching strength and stiffness are very high.

3. The metal stamping parts are generally free of chips, natural, less material consumption, and do not need any heating equipment. The processing method of the invention can save materials and energy.

4. Metal stamping parts processing, high production rate, simple operation, easy to realize mechanization and automation. This is because the metal stamping die and metal stamping equipment rely on finishing, with dozens of strokes per minute. Generally, according to the number, as high as hundreds or even thousands of times of pressure per minute, each stamping stroke may be one stamping.

The operation steps of surface treatment of metal stamping parts are as follows:

1) Surface polishing is usually used in daily necessities for a long time. For example, we produce a comb, and the comb is made of hardware by stamping. The edge of the comb is very sharp. We have to polish the sharp part of the edge into a smooth face,

2) Spray paint processing: hardware factory in the production of large hardware products are used in the spray painting process, through the spray painting process to avoid rust hardware.

3) Electroplating is also a common processing technology of hardware processing. Through modern technology, the surface of metal stamping parts can be electroplated to ensure that the product will not mildew and rust for a long time. The common electroplating processes are: screws, stamping parts, batteries, turning parts, accessories, etc.
