部品直接组成制品的基本组成部分。。与大连数控加工零件差别的是它纷歧定是零件，，也可以是半制品或其它公司的制品，，如：一幢屋子其中配有空调，，那么相对屋子空调就是一个部品；；；若是你是生产空调的，，而压缩机你不生产，，那么相对空调来说压缩机就是一个部品。。与原质料差别的是它是经由加工或者成型可以直接装配或使用于制品上的组成部分，，如：空调上的按钮是一个部品，，组成按钮的塑胶却不是一个部品。。部品包括零件、外购半制品、外购制品。。

Parts directly constitute the basic components of the finished product. Unlike Dalian CNC machining parts, it may not necessarily be a part, but can also be a semi-finished product or a finished product from other companies. For example, if a house is equipped with air conditioning, then the air conditioning in the house is a component; If you produce air conditioners and you don't produce compressors, then compressors are just a component compared to air conditioners. Unlike raw materials, it is a component that can be directly assembled or used in finished products through processing or molding. For example, the button on an air conditioner is a part, but the plastic that makes up the button is not a part. Components include parts, purchased semi-finished products, and purchased finished products.
