根据我国对钢材供需形势的分析可以看出，只是一味地追求原有的设计方案和工艺方法已不合时宜，因为钢材的供应有时不那么及时．且价格昂贵。这就要求我们以发展的眼光从另一面来开拓我们的产品．当前工程塑料的广泛开发和其潜在的应用能力．将促使我们开辟一个新天地。工程塑 According to our analysis of the situation of supply and demand of steel, we can see that it is outdated to pursue the original design scheme and technological method blindly, because the supply of steel is sometimes not so timely. And expensive. This requires us to develop our vision from the other side to open up our products. The current extensive development of engineering plastics and its potential applications. Will prompt us to open up a new world. Engineering plastic
