Casting mold industry gains opportunities for development

In recent years, China's molds have grown at an average rate of over 15%, which is more than double the average value of China's GDP. According to the “National Basic Situation of Mold Specialized Plants” compiled by the China Die and Mould Industry Association Management and Management Committee, casting molds account for approximately 5% of the total output value of various types of molds, and the annual growth rate is as high as 25%. Luo Baihui, head of the International Die & Metals and Plastics Industry Suppliers Association, believes that the high growth rate of the foundry mold industry is mainly due to the rapid development of China's automobile and motorcycle industries and the rapid growth in the production of casting molds. As we all know, the castings have a wide range of applications, and they cover almost all industrial fields. Among them, the castings of automobile parts are ranked first in terms of their number, varieties, strict requirements, high quality and non-ferrous metal materials. , The largest share of the entire foundry industry.

At present, China’s auto and motorcycle industry has entered a period of rapid growth, and its output has increased significantly for many years in a row, ranking first in the world, especially for cars that are closely associated with the foundry industry. The growth is fastest, and it is rapidly increasing for complex, large-scale, The demand for precision casting molds, and therefore as an important support for the foundry industry - the casting mold industry has achieved unprecedented opportunities for development. It can be predicted that in the next few years, the production of casting molds in China will still obtain strong thrust mainly from the domestic automobile industry.

Compared with countries such as Southeast Asia and the Middle East, China's molds have advantages in terms of technology, quality and price, and their export prospects are promising. While foreign-funded enterprises enter China, the return of molds and exports will also become an important part of China's mold exports. Luo Baihui said that because China's mold production costs are much lower than foreign countries, with the improvement of mold manufacturing technology and quality, not only can reduce the import of mold, but also may gradually open up the export market, export more mold to foreign countries. During the 12th Five-Year Plan period, mold imports will continue to maintain its growth momentum in the short term, and mold exports will have great development.

In the tide of economic globalization, the international division of labor in the process of industrial development is taking shape. Based on the pressure of cost, foreign investors purchase large quantities of castings in China, and even set up casting production bases in China. It can be predicted that in the long term, China will still The company is responsible for the production of international non-ferrous metal castings and products. On the other hand, due to the unremitting efforts of mold colleagues, China's casting mold production level and ability have greatly improved, the gap between mold quality and advanced industrial countries gradually narrowed, low prices drive the sharp increase in foreign purchases, the huge demand for overseas mold market China's mold industry is booming.

The casting mold market is extremely active. As the Chinese economy continues to grow, the foundry industry will maintain high growth and drive the development of the foundry mold manufacturing industry. It is expected that there will be great room for further development in the overall demand for molds.

Calcium Carbide

Calcium carbide is an inorganic substance, the chemical formula is CaC2, the main component of calcium carbide, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc.

Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; at the same time, acetylene-oxygen flame is widely used in metal welding and cutting.

Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The relative humidity is kept below 75%. The packaging must be sealed and protected from moisture. It should be stored separately from acids and alcohols, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.
