Refers to the ability of a material to resist local deformation, especially plastic deformation, indentation or scratches. It is a measure of material softness and hardness.

In the cutting process, the thin wall is easily deformed by the cutting force, which leads to an oval or a “waist shape” with a small middle and large ends. 

There are many reasons for the deformation of aluminum parts, which are related to the material, the shape of the parts, and the production conditions.

A set of reliable plastic mold design is mainly reflected in the quality of the molded plastic products (appearance quality and dimensional stability), convenient, rapid, and concise processing and manufacturing, which saves money and manpower, and leaves room for correction and improvement.

It is worth pointing out that no “lighthouse factory” has completed digital transformation alone. They all rely on partnerships to acquire or jointly develop new knowledge. And Microsoft has become the choice of many business partners.

The task of mechanical structure design is to draw a specific structure diagram based on the design task on the basis of the overall design conception, and to draw a specific structure diagram to achieve the functions required by the design.

Surface roughness Ra is a symbol often used by our machines. It is basically our old friend. If that drawing does not have it, it is estimated that the drawing will be scrapped. It is such a symbol for dealing with every day. Do you know why 0.8 is used , 1.6, 3.2, 6.3, 12.5, and not other numbers? I believe that members of the community have also encountered this confusion when they are learning and using it, but they have not studied the answer in detail. All of this must start with the great mathematics, and now I will explain it in detail.

Is it designed based on KKD (experience, intuition and courage) alone? Explain the advantages and necessary knowledge of tolerance design concisely and easily!

There are many transmission modes. Among the four major types of transmission methods (mechanical, electrical, hydraulic, and pneumatic) that are currently widely used, none of the power transmissions is perfect. Today I will share with you the comparison of the pros and cons of the 4 transmission methods.

Stability is well understood, the ability to maintain or restore the original balance form under force. For example, the thin rod under pressure suddenly bends, the load-bearing thin-walled member folds, or the column of a building collapses. Today I will mainly talk about the understanding of stiffness and strength.

When I came into contact with people in 96 and 97, I was generally interested in electricity. Many of my friends are also learning and don’t want to work on machinery alone. But this is also a disadvantage. It feels bad for people and feels not doing business properly. The roots of machinery are not well established. But 96 and 97 have strong learning ability, after all, they are young people.

Solenoid valve is an automatic basic element used to control the direction of fluid, which belongs to the actuator; it is usually used in mechanical control and industrial valves to control the direction of the medium, so as to achieve the control of the valve switch.
