Carburizing: Helping Customers Solve The Problem Of Surface Wear Resistance

< p > no longer remember what time it was. It was like the year before last or last year when there was a customer phone enquiry, a bar of SCM415, to be made of a shaft wheel. I didn't know exactly what part, but I remember his request very clearly, because I was also in touch with the industry very soon, so I remember that these professional terms or things are very clear.

Customers request the SCM415 < a href= "//www.sjfzxm.com/news/list.aspx ClassID=101112107108" > bar heat spot < /a > to HRC48, and the surface must be rubbed regularly, so the hardness of the surface must reach HRC58.

< /p >

< p > in fact, the hardness of the material itself can only reach HRC48-52. The customer's request is undoubtedly baffled by the lack of experience at that time.

Asking colleagues and colleagues is also a bit of a slog, and I don't know how to solve them.

Later, we asked our engineers, he said that the hardness inside the shaft is not so high, the standard SCM415 material can be achieved, this is not a problem.

Because the shaft must be rubbed, the hardness and wear resistance must be very good, so there is only one way to solve this problem.

Because the customer specifies this material, the material is not considered to be replaced by other materials.

So we can only think of this way without changing the material of our customers.

< p > later, after analyzing the method with the customer, the customer was very happy and sent me the sample immediately.

Two days later, the customer answered that he had not started the work yet, and had to wait another two days, because their whole process, accounting and so on were still in progress.

Two or three days later, I called again, and the customer said that the carburizing treatment was good enough yesterday, which was more satisfactory than expected.

< /p >

"P >" in this way, a surface carburizing treatment can help customers solve problems. In fact, not only SCM415 material can do such treatment, the standard high carbon carbon steel can be used as heat treatment material, all can do this process to change the material's wear resistance and hardness.

We can use this product when customers have such a requirement.

< p > footwear several main shoe material raw materials < /p >

< p > < strong > < a > href= > //www.sjfzxm.com/news/list.aspx > ClassID=101112107102 > PU material > /a > /strong > /p >

< p > PU, that is, polyurethane material, which is dissolved into gelatinized and then heated into the model to make it foam. The finished product has smooth surface and will become yellow and corroded after a long time. It has a certain degree of shock absorption and stability.

The biggest advantage of PU midsole is elasticity and toughness, smoothness, and a kind of rubber texture.

This is the most widely used material in the bottom.

< /p >

< p > < strong > PHYLON material > /strong > /p >

< p > PHYLON plastic particles are heated and foamed and poured into the model for pressure cooling. The surface is white and wrinkled. Besides the general EVA/PHYLON shock absorbing function and the wear-resisting property of the rubber outsole, it is light in weight and exquisite in appearance, and has excellent rebound performance at the same time. It provides a good energy return.

< p > < strong > < a > href= > //www.sjfzxm.com/news/list.aspx > ClassID=101112107105 > EVA material > /a > /strong > /p >

< p > when the EVA plastic particles are injected into the mold, the middle sole of the shoe formed once after heating by high temperature is called a foaming middle sole, that is, the middle sole of the EVA.

The finished product has rough surface, light weight and slow vibration.

< p > < strong > LUNAR material > /strong > /p >

< p > Lunarlite foam is co developed by NIKE and NASA. It is 30% lighter than the medium EVA/PHYLON material commonly used. Under the premise of reducing energy loss, it has good reaction speed and flexibility, can reduce muscle fatigue, and provide rapid recovery in sports and training.
