You plan to start your business in Customized Mechanical Parts, which involve a lot of techs such as: Precision Casting, Die Casting, Fabrication, Molding, Extrusion, Stamping, Forging, etc.
Make a report (500-800 words) for one of these techs. This report will help to improve your understanding of this business. Reports can be in Chinese or English. If in Chinese, you shall translate some key words into English.
