FAQs About Prototyping to Mass Production
What is your prototype-to-mass-production transition process?
expand_less expand_moreA: We adopt phase-gated workflow: validated prototype design review + full DFM analysis → tooling design and production equipment setup → multi-round pilot run → formal high-volume production launch.
How to keep mass-produced parts consistent with prototype specs?
expand_less expand_moreA: Apply equivalent manufacturing process and unified CAD drawings for samples and bulk parts; carry out SPC real-time monitoring, FAI and periodic sampling inspection during mass production.
Key scaling challenges and corresponding solutions?
expand_less expand_moreA: We tackle material instability, tight tolerance loss under high-speed machining and tool wear via certified suppliers, high-precision custom tooling and continuous lean optimization.
How long for tooling and pre-production setup?
expand_less expand_moreA: Standard precision parts need 4–8 weeks; rapid tooling and existing modular fixture options are available for urgent projects after design finalization.
Difference between prototype QC and mass production QC?
expand_less expand_moreA: Prototype uses 100% full inspection for design verification; mass production applies SPC monitoring, automatic inline check and AQL sampling audit for batch repeatability.
Can design be revised after prototyping before mass production?
expand_less expand_moreA: Design changes before tool fabrication are low-cost; post-tool modification may cause extra fixture cost and schedule adjustment, our team evaluates all ECO transparently for optimal plans.
