Station 02 / 10

Prototyping 手板

Looks-like and works-like models: CNC, SLA, urethane casting. In Shenzhen this takes days, not weeks.

What happens at this stage

You make prototypes: early physical versions of your product, built without expensive production tooling. A "looks-like" prototype shows the appearance; a "works-like" prototype proves the function. Shenzhen prototype shops (手板厂) use CNC machining, 3D printing and urethane casting, then paint and finish parts so they look real.

Why it matters

Holding the product in your hand shows problems no screen can: parts that don't fit, buttons that feel wrong, a case that's too big. Fixing these now is cheap. Fixing them after a steel mold is made is not.

What it costs and how long

Single parts can cost from tens to hundreds of dollars depending on size and finish. Shenzhen shops often turn prototypes around in 3–10 days. Expect several rounds.

Common mistakes

  • Treating a prototype as proof the production version will behave the same (prototype materials differ)
  • Ordering one part at a time instead of the whole assembly together
  • Not telling the shop which surfaces are cosmetic

Who helps

Prototype shops, 3D printing bureaus and CNC shops. Filter the directory by process. Read the process hubs for what each method is good for.
