\nConfirm shipping method and change control
\nDecide on shipping terms and transit mode, and establish how design changes, drawing revisions and tolerance updates will be communicated and approved. For TDAC, similarly ensure that any changes in travel dates or flights are updated on the official system according to allowed rules.tdac.immigration<\/span>+1<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<\/li>\n<\/ol>\n<\/span>Use Cases<\/span><\/h2>\nScenario:<\/strong> Concept and appearance prototype before customer demo
\nTraditional approach:<\/strong> Internal teams build rough models with limited finishing, then travel without fully validated physical samples.
\nWith 6CProto:<\/strong> Upload CAD and drawings, request rapid prototyping with suitable 3D Printing or CNC Machining, and plan a TDAC\u2011compliant trip to review parts with stakeholders.
\nResult:<\/strong> Higher confidence in form and fit during meetings, reduced need for repeat travel and improved decision\u2011making.<\/p>\nScenario:<\/strong> Functional CNC prototype for industrial equipment
\nTraditional approach:<\/strong> Local job shops produce single parts with informal tolerances and minimal documentation, making it hard to roll into a controlled production run.
\nWith 6CProto:<\/strong> Use CNC Machining services with defined materials, critical tolerances and inspection expectations, and schedule factory visits with TDAC submitted in time.
\nResult:<\/strong> Dimensional control is aligned from prototype to later batches, and site visits focus on process optimization rather than basic quality issues.<\/p>\nScenario:<\/strong> Low\u2011volume bridge production for a new product
\nTraditional approach:<\/strong> Teams wait for full tooling or high\u2011volume suppliers, delaying market tests and requiring multiple trips to coordinate.
\nWith 6CProto:<\/strong> Combine Rapid Prototyping, Injection Molding or Urethane Casting to build bridge production lots while planning targeted travel for line trials.
\nResult:<\/strong> Faster pilot runs, earlier customer feedback, and better use of travel budgets.<\/p>\nScenario:<\/strong> Custom jig, fixture or sheet metal enclosure
\nTraditional approach:<\/strong> Jigs and enclosures are fabricated ad\u2011hoc, with limited CAD control and inconsistent dimensions, complicating on\u2011site installation during trips.
\nWith 6CProto:<\/strong> Utilize Sheet Metal Fabrication and CNC Machining with controlled drawings and GD&T, and align travel dates with agreed lead times and TDAC submission.
\nResult:<\/strong> Fixtures and enclosures fit correctly on installation, minimizing on\u2011site rework and unplanned extensions of stays.<\/p>\nScenario:<\/strong> Additively manufactured complex geometry for R&D
\nTraditional approach:<\/strong> Complex parts are delayed by machining constraints or multiple suppliers, and travel occurs before physical prototypes are ready.
\nWith 6CProto:<\/strong> Produce intricate R&D parts via 3D Printing processes such as SLA, SLS or SLM, and plan travel once prototypes are available for testing.
\nResult:<\/strong> Lab and field tests can be conducted during a single TDAC\u2011compliant trip, improving utilization of engineering time and travel resources.<\/p>\n<\/span>FAQ<\/span><\/h2>\nDo I still need TDAC if I have a visa or visa exemption?<\/strong>
\nTDAC is a separate requirement from visas or visa exemptions. Many non\u2011Thai travelers must submit TDAC online even if they already meet visa rules; check current guidance on the official TDAC website or Thailand immigration channels before traveling.tdac.immigration<\/span>+1<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n
