Need to increase the degree of specialization of foundry industry of our country

Our foundry enterprises specialized level is not high; Casting production technology and equipment is poor, weak independent innovation ability; The casting quality is not high; Environmental pollution is serious; Higher energy and material consumption. From casting powers this goal, we have quite a gap. The expert points out, China's foundry industry difference compared with the developed countries, mainly displays in the comprehensive quality of the casting, casting production technology and technical equipment such as basic conditions. In terms of dimensional precision, casting in our country is generally lower than the developed countries level 1 ~ 3, the surface roughness of developed countries than the coarse 1 ~ 2 level. Such as the roughness of the engine cylinder block, 100 to 25 microns in our country, foreign 25 to 12.5 microns. In terms of the composition of casting material, ductile iron cast iron products ratio is a measure of a country casting composite structure is an important measure of quality.
Enterprises need to further expand the size of the superior enterprises to improve the technology and equipment level of enterprises; Must increase investment in science and technology, the establishment of enterprise's r&d center and a series of production, study and research and development system, to promote independent innovation; Must put environmental protection and labor security as a major event to pay special attention to; Must cut down the consumption of energy and raw materials; Must further develop casting professional talents, strengthen the technical training of staff, improve the industry technology and the quality of the employees.
