The requirements of the automotive industry for the mold industry

With the increasing economic and living standards, the number of cars has also risen. When we saw so many cars, we couldn't help but realize the huge output behind the manufacturers. Undoubtedly, China's mold industry has driven the development of the automotive industry. Then what impact does the mold have on automotive manufacturing? What are the automotive industry's requirements for the mold industry?

First of all, the mold is adapted to the direction of mass production. Therefore, it is thought that the mold is actively and widely used in production and manufacturing. It is the development direction of industry and manufacturing.

In the past Shanghai brand automobile era, the outer shells of Shanghai and Hongqi cars were made by workers using wooden hammers. Now that the public has an annual output of 500,000 cars, imagine how it can be realized if it is still artificial. This is simply a fantasy.

The advantages of using molds are that they can reduce costs, save time, increase production efficiency, and enable companies to remain invincible in the current fierce competition. However, Professor Li also pointed out that at present, the mold used in automobile manufacturing, or plastic components, lights, steel shell and other accessories. The real car core engine still uses cutting technology and does not use mold technology.

In addition to the engine can not use the mold technology, the crankshaft used in the car can not use this technology. What are the reasons? We all know that the components that use the mold forming technology have a certain degree of adaptability, and it itself requires a relatively thin, but also a certain degree of molding. Thickness and diameter components like crankshafts and connecting rods are more difficult to stamp with dies. At present, the most used one is to use a die to make a crankshaft blank, and then use cutting for finishing.

When the machining accuracy is very high, the molds are often insufficient. The precision that a very good precision mold can reach now is in the range of 0.1-0.01 mm. Compared with the previous molds, the precision is already a big step forward. However, such components as the engine require an accuracy of one thousandth of a millimeter or less. Therefore, it is not possible to completely replace the cutting process with a mold.

The mould now has a great leap in its finish and roughness. However, the mold itself is also manufactured by the machine tool. If the precision of the machine tool manufacturing itself cannot pass, then can the manufactured product be of high precision?

The adoption of mold technology is an inevitable trend for adapting to fierce competition. It is of utmost importance to increase the competitiveness of the mold itself to meet the needs of the market. It is the requirement of the development of the mold industry to improve the precision of molds, and it is also the voice of the automobile and other industries.
