Market Analysis of China's Mold Material Market

At present, the vigorous development of the domestic mold market has great demands on the performance of mold materials, the number of varieties, etc. In this push, the mold material market has also been unprecedented development.

First of all, the world’s major mold material manufacturers are rooted in the Chinese market. For example, Sweden’s Yishengbai, Japan’s Hitachi, Datong, Toyo Carbon, France’s Obudou, US’s Finkel, and Germany’s Goriz , SGL, etc., among which Sweden’s wins and 100s accounted for a very large market share. Secondly, domestic mold material suppliers also developed rapidly, especially the development of domestic steel. The overall trend is rising and developing. The sales amount accounts for the largest share of the market, but the life of molds made with domestic materials is worse than that of imported materials; again, many mold material suppliers not only supply mold materials, but also provide many ancillary services such as machining and heat treatment. Increase the added value of mold materials.

On the other hand, with the development of the material market, the phenomenon of misuse and indiscriminate use of mold materials (mold steel) has also occurred from time to time. The waste of mold steel products is very serious, which not only brings cost increase to mold enterprises, but also brings about Pollution is also not conducive to the orderly development of the entire material market. The reasons are mainly the following two points.

(1) Where there is a large amount of mold steel, it is also an area where a large amount of fastener mold scrap is generated. For example, in the Guangdong region, waste molds made of Crl2 (Crl2MoV) and 4Cr5MoSiVl (H13) steels are calculated in 10,000 tons per year, and 9Cr2Mo (9Cr2MoV) steel is also being used more and more. These three kinds of materials are used to make cold work molds (ceramic molds, cold punches), aluminum extrusion molds and cold roll.

(2) The lure of profiteering. The use of waste and conservation of resources are in line with increasing production and saving, and are also in line with the viewpoint of sustainable development. The proliferation of inferior mold materials has caused huge losses. Many steelworkers involved in the lure of profits, low-cost acquisition of waste molds, melting in the intermediate frequency melting furnace after casting into small steel ingots, and casually forged Yuangang and plate, steel supply and marketing of low-cost commercial acquisition in the market after the sale . Some of the mold manufacturing companies do not have in-depth knowledge of mold materials and purchase these materials under low-cost inducement, thus flooding inferior materials. In particular, a large number of home-based mold making plants are the main places for inferior materials.

The production of inferior mold materials not only encourages the arrogance of opportunistic molecules, but also causes huge losses to mold manufacturers and heat treatment plants. Some cold molds made by inferior Cr12 and Cr12MoV will burst during heat treatment, wire cutting, grinding and even storage in the warehouse. The analysis results show that the eutectic carbides have an uneven degree of 8 and the carbides are net. In the distribution, massive carbides in the form of blocks and horns reach grade 5, and the general loosening and central looseness are severely exceeded. Some of the disadvantages caused by these inferior materials may be due to unskilled heat treatment workers, but more importantly, the relevant properties of the mold materials themselves have not yet reached the relevant standards. Therefore, in order to increase the life of the mold and eliminate the waste of materials, it is recommended that relevant effective measures be adopted:

(1) Resolutely eradicate in legal proceedings. Mold steel is a relatively expensive material. Recycling of scrap steel is in line with the sustainable development, but it needs to be carried out by a regular steel mill. Private home workshops must not be used to remanufacture mold steel to prevent improper use of technical force, process level, and inspection methods. It cannot meet the requirements for the production of alloy die steels, and in particular it must use legal means to resolutely stop production activities aimed at making profits.

(2) Establish an impartial arbitration institution. An impartial arbitration institution is an effective measure to curb the proliferation of these materials. However, such institutions must have sufficient technical skills and require fair practices to prevent them from being unfairly affected by material suppliers’ money.

The elimination of inferior materials and the right choice of mold materials are important factors in improving the competitiveness of the mold market. A wide variety of molds, materials are the basis, the shape of the mold is supported by the foundation, then what aspects should be noted when selecting the mold materials?

(1) Molds with large part yields and stable dimensions should be made of high-performance materials. Such mold materials can also be used for low-vacuum surface hardening to increase the durability of the mold to a new level.

(2) The shape of the mold is complex, the precision is high, and the manufacturing cycle is long. The processing fee of the mold far exceeds the material cost of the mold. This mold should also be made of high-performance materials.

(3) High-stressed molds are made of high-performance materials and their durability can be improved by using inexpensive surface-strengthening techniques.

(4) Molds with small parts yield, simple shape, low stress, easy to manufacture standard part molds, often reshaped molds, can be made of ordinary steel, cast iron or even non-metal.

(5) The material selection of molds should be combined with national resources and the steel elements with rich elements in China should be selected.

(6) Materials need to be selected from the viewpoint of sustainable development. The new steel number should be used as far as possible to turn scientific research achievements into productivity, and to improve the quality of the mold.

(7) Correctly look at the development of domestic mold materials.
