4A Zeolite has a pore size of 4A, which absorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, and does not adsorb any molecules (including propane) with a diameter greater than 4A. The selective adsorption performance of 4A Zeolite for water is higher than any other molecular. 4A molecular sieve is one of the most used molecular sieve desiccants in the industry.

Due to China's abundant labor resources and vast market, coupled with the support of national policies, in recent years, the domestic die-casting mold industry has developed rapidly. China is currently in a demographic dividend period and has a large amount of labor. Compared with developed countries, the cost of labor in our country is relatively low; while the die-casting mold industry is steadily advancing in the traditional market, it constantly develops new markets, and the continuous development of the marginal market makes the die-casting molds. The market space of the industry is very broad; some policies issued by the country have also created a good development space for the die-casting mold industry. Labor force, market, and policies have become powerful boosters in China's die-casting mold industry.
At present, the die-casting mold industry in developed countries such as the United States, Germany, and Japan is suffering from the economic contraction. The mold demand market is in a slump, and the rising prices of raw materials make it increasingly difficult for the mold industry in these developed countries to develop. Based on the above factors, China's die-casting mold industry is expected to become a global leader in the production of die-casting molds.
