No, you can’t manufacture that like Apple does (2014)
>> CNC machining at scale
CNC machining is fantastic for prototypes and pretty awesome for high margin parts like hip implants and turbine blades. It is not for consumer devices. Figure out a way to cast your metal parts.Having a manufacturing back ground, I did extended workbench management early in my career, this is just wrong. Sure, at high volumes casting and injection moulding is unbeatable at per unit costs. At smaller volumes, not so much. Casting and moulding tools cost a fortune, and those upfront NRC are just prohibitive for small volumes. So smart CNC machining it is. Added benefit, there are tons of small CNC machining ships around that are really good at that.Nothing to add on ejector pin marks, if you see those on the outside of your part, your part design and manufacturing / tool design sucks. No need to be a billionaire genius, just a decent plastics engineer.But since the target audiamce of this article are start-ups, it kind of makes sense, doesn't it? Brcause how many start-up founders have a solid grasp of hardware manufacturing, design, tooling and manufacturing processes? Especially those that want "Apple" without understanding what that means deffinitely don't.
