Section One:
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.

Section Two:
Attached is a machining drawing. We need a drawing for casting so all machining dimensions are not needed. Make a new casting drawing in name of BACO ENGINEERING. Make sure all casting dimensions are clear. Leave Machining surfaces 3mm casting allowance. Either 2D or 3D drawing is acceptable.

Please send me both drawing and report in PDF format.
