Stay Machining of mechanical parts Field ， When it comes to good Machining plant Think of four families 。 Copper products processing in China 、 Aluminum processing And stainless steel processing enterprises ， Stay In many ways Stay Imitate four families ， Progress in learning 。 It should be noted that ， Four foreign families have fully dominated the global hardware processing supply chain system ， So that the strong will remain strong ， Occupy the highest end of global value chain 。

　　 Since the reform and opening up ， Chinese Machining of mechanical parts Many enterprises are customers of four families ， Or partners 。 Stay China ， If we can supply four families ， That must be good Machining plant 。 We know ， The theory of comparative advantage has no meaning of competition ， It only requires Chinese hardware processing enterprises to meet their own requirements 。 Therefore ， Made in China 2025 Put forward ， It means abandoning the theory of comparative advantage ， Competition is inevitable 。

　　 Many of them do foreign trade Machining of mechanical parts Enterprises have deeply felt this from the trade friction between China and the United States —— Because Made in China 2025 It's all about breaking through ， Do not wish Aluminum processing 、 Copper products processing 、 Stainless steel processing will stay forever Stay Middle and low end of value chain ， Instead, we should strive for high-end hardware processing value chain 。

　　 When China Well Machining plant Aimed at Machining of mechanical parts High end of industrial chain Field ， It must not be a simple competition for hardware processing trade ， It's right. Machining of mechanical parts Competition for technical standards 。 The deep reason of Sino US trade friction ， Not just Stay Trade level ， But the deep background of competitive advantage reconstruction 。
