Selection of mold steel?

Science Classroom / By

There are usually two reasons for the steel grain phenomenon in the mold: one is the problem of the mold steel itself, many mold makers choose poor quality (cheap) steel to make the mold in order to save cost, resulting in the surface of the mold after the mold polishing to appear grain, and some fine lines. At the same time, under the light will lead to distortion of the light, mold polishing can only reduce the phenomenon of mold steel grain. Secondly, the skill of the mold polisher is not good.

What is pitting ?

Science Classroom / By

Is it a material problem or a technique problem that produces pitting in polishing, and if it is a technique problem, can it be avoided? In order to solve this problem, we need to know how this problem occurs, and there are 3 reasons for this problem. Please read on to find out

Mirror machining is realized in several ways

Science Classroom / By

Mirror machining means that the machined surface can reflect the image like a mirror, this level has reached a very good quality of the surface of the workpiece, mirror machining is not only able to create a high “face value” for the product, but also reduces the notch effect and extends the fatigue life of the workpiece; it has an important significance in a lot of assemblies and sealing structures.

Sintering mechanism

Science Classroom / By

The specific surface area of the powder surface will change because of the size of the powder particles, when the powder particles are large, the specific surface area will decrease, when the powder particles are small, the specific surface area will increase, the size of the specific surface area relates to the size of the …
