The current forging machinery industry in the domestic market share of 57%

2014-09-16
China foundry and forging machinery industry still exists for a long time, specifications complete, but in a surplus of low-grade products, the lack of high-grade products status.
Forging machinery industry is traditionally considered to be simple and extensive equipment, the use of the environment is far worse than other machine tools. Despite the considerable amount of existing products, high level of manufacturing fine casting equipment, forging equipment and complete sets of production lines, is still difficult to change the low barriers to entry, making extensive condition.
Forging machinery industry started in the last century 50s, in the seventy or eightys that realize the main forging machinery of provide for oneself, but also rely on the products of high quality and low price in the world market share of a growing share of exports, with 80% year of forging machine.
China foundry and forging machinery industry still exists for a long time, specifications complete, but in a surplus of low-grade products, the lack of high-grade products status.
From our country forging machinery import and export data to prove: import is 3.3 times the export, import CNC forging machine is 1.78 times the total exports. Casting Machinery Import & Export contrast also run in the same groove. It reflects the market for high-end products significantly increased the demand, also reflected in the domestic high-end products in the technical level, the output value are obviously inadequate, unable to meet the needs of users in product quality, technical indicators, customer service etc..
For small and medium-sized specifications, ordinary type products we only solves no problems, high-end products still rely on imports; in a large, heavy, special equipment, the problem is more prominent. We made CNC machine tools of domestic market share has reached 57%, but the share data constitute the most low-grade NC machine tool, part of a high-end low proportion.
