Level 2 of the Five Levels of Mechanical Engineering
People who deliberately bring surprises to the world. Examples include Wozniak, who created the first practical personal computer (there is a dedicated chapter about him in Professor Chi’s book *Crossing Boundaries*, which also features a photo of him with the author); John Theofilou, the “father of DSL”; the chief designers of the iPhone and Google Glass; and the previously mentioned Rubin, Dean, and others. What sets them apart from third- and fourth-level engineers is the originality of their work and its impact on the world. Of course, their work is not scientific research, which distinguishes them from scientists.
On this point, Dr. Wu Jun has specifically noted that Silicon Valley companies have a diverse culture; when developing products, they take a global perspective, ensuring that multilingual versions are released no later than six months after the English version. As a result, many of these companies’ products are world-class. He also mentioned that WeChat’s international expansion has not gone smoothly, and it remains a smash hit only within China.
Custom Machining of Aluminum Parts
You can order custom aluminum parts online by uploading your CAD files to the platform. This allows you to receive an instant quote and ensures rapid production.
Common Aluminum Grades
Aluminum 6061-T6: The most popular choice for general use, offering great machinability, weldability, and a strong strength-to-weight ratio.
Aluminum 7075-T6: An aerospace-grade alloy with high hardness and strength comparable to steel.
Aluminum 5052-H32: Features superior corrosion resistance and formability, making it ideal for marine and sheet applications.
Popular Finishing Options
Anodizing (Type II & III): Enhances corrosion resistance, wear protection, and surface hardness.
Powder Coating: Adds a durable, colored protective layer.
Bead Blasting / Tumbling: Smooths out rough edges and removes machine marks.
