Surface treatment of stainless steel parts - PTJ Manufacturing Shop

A large number of stainless steel plates are used in modern decorative engineering and precision machining. Many parts need to be surface treated after processing. Many friends think that stainless steel does not need surface treatment. In fact, this view is wrong. PTJ (MINGHE) Factory specializes in the precision machining of stainless steel plates. The parts include medical equipment, auto parts, drone parts, office automation parts, etc. which are common to us. Next, following Hongweisheng, we explore the precision machining of stainless steel plates. What surface treatments are there after the parts are completed?

1. Mirror, the industry calls it 8K:

The mirror surface is that the surface of the parts processed by the stainless steel plate is polished like a mirror by a special process, and the brightness can even be photographed. The raw materials of the stainless steel can also be mirror-finished on the surface;

2. Sandblasting:

The effect of sand blasting is to make the surface of the stainless steel sheet parts a fine beaded sand surface, but the stainless steel blasting is also divided into matt sand and bright sand. The matt sand is carried out under the general surface smoothness of the product, while the bright sand is generally It is done after grinding into a mirror;

3. Drawing, snow sand, ordinary sand:

Brushed, snowflake sand and ordinary sand are called matte. The three kinds of surface treatments are mainly sand grains on the surface, the sandstone is the thickest and the longest, followed by ordinary sand. The sandstone of snowflake sand is Most like small. Of course, the mechanical equipment for processing it is different. At present, the surface treatment that many manufacturers need to do is mixed sand. The common practice is to grind ordinary sand first and then do the drawing;

4. Titanium plating:

At present, many people say that the color stainless steel parts are actually the result of titanium plating on the surface, such as gold color, rose gold, sapphire blue and so on.

5. Titanium withdrawal:

Many people think that the stainless steel after titanium removal is colored stainless steel. In fact, the significance of titanium removal is that the parts are now plated with titanium, and then the color is removed from a place to a specific place to achieve a specific pattern and shape;

6. Copper plating:

The surface of stainless steel parts is plated with copper. Some customers do not understand the material technology or even require the manufacturer to use copper-containing stainless steel. In fact, this is to choose gold plating or bronze plating on stainless steel parts. This process is generally more common when making crafts. Special colors are used for special purposes, such as plating in bronze and then making it old, which is the processing technology needed in the crafts field.

7. Embossing, the industry calls it embossing:

But the true meaning of embossing and embossing are two concepts. The embossed stainless steel is the small diamond shape and square of the surface of the product we see every day. Embossing is the way to impact on the surface of stainless steel. The most intuitive performance is that the embossing can not feel the bumps from the back, but the embossing can be felt;

8. Laser:

This process is currently used in many applications, similar to laser engraving;

9. Etching:

Etching is the effect of the unevenness on the surface of the stainless steel by chemical agents. If the customer has etching requirements, the manufacturer is generally required to etch the pattern or text on the surface;

10. No fingerprint:

It is to apply a layer of oil on the surface of stainless steel parts, and achieve anti-fingerprint and anti-oxidation effect after high temperature baking;

11. The chaos, also known as the grain:

After the surface treatment is completed, the surface of the stainless steel part will show a circle of sand patterns from a distance, and irregular chaos from a close view;
