Test intent
Every prototype should be tied to a clear fit, function, appearance, assembly, or manufacturing question.

Product Development Manufacturing Support
Prototype-to-production support for engineering teams validating fit, function, assembly, and appearance.
- Appearance models
- Functional prototypes
- Test fixtures
- Pilot housings
Industry overview
Purpose-driven prototypes that answer specific design and manufacturing questions.
Product development teams use printed models, machined prototypes, vacuum-cast housings, fixtures, and trial molded parts to evaluate fit, function, assembly, ergonomics, and appearance at different stages.
The best prototype route depends on the question being tested. A fast appearance model, a load-bearing machined part, and a pilot molded housing need different materials, tolerances, finishes, and interpretation of results.
Manufacturing challenges
Common mechanical questions in product development projects.
Process equivalence
Printed or cast materials may look similar without matching final molded or machined performance.
Design maturity
Frequent revisions require controlled file versions, drawing notes, and decision ownership.
Production transfer
Prototype geometry should evolve into draft, tooling, finish, and inspection rules for the intended process.
Suitable processes
Manufacturing routes connected to the part geometry.
Typical materials
Material options that still require application approval.
Typical parts
Component families for product development engineering teams.
Appearance models
Functional prototypes
Test fixtures
Pilot housings
Assembly samples

Quality considerations
Inspection follows the drawing, function, and process risk.
- QC 01
Identify what the prototype is expected to prove before selecting the process.
- QC 02
Control model and drawing revisions throughout quotation and production.
- QC 03
Document known differences between prototype and intended production materials.
- QC 04
Inspect the features needed for the planned fit, function, or assembly review.

Review exampleFAQ
Product Development manufacturing questions.
Which prototype process should I choose?
Choose according to the question being tested, required material behavior, geometry, quantity, appearance, tolerance, budget, and delivery need.
Can a vacuum-cast housing represent injection molding?
It can support appearance and assembly review, but polyurethane behavior and silicone-tool details are not automatically equivalent to production resin and steel tooling.
Can Kewei provide DFM before production tooling?
DFM support can review walls, draft, ribs, bosses, undercuts, gates, ejection, assembly, finish, and inspection needs before tooling release.
