Desired Daily Output: Target number of blocks per shift.
Exact Block Specifications: CAD drawings or precise dimensions for each product type.
Tingkat Otomasi: Detail every desired component (auto pallet feeder, stacker, mixer, etc.).
Power & Voltage: Your country’s standard (e.g., 415V/50Hz/3Phase).
Spare Parts List: Specify a starter kit of critical wear parts.
Branding: Company logo color for the machine’s paint job.

Phase 2: Supplier Selection & Vetting (The Most Critical Step)

This phase is the cornerstone of E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness). Do not skip it.

Verify Legitimacy: Use platforms like Alibaba’s “Supplier Assessment” or official Chinese business license websites to confirm the company’s legal registration and scope.
Request Evidence of Expertise: Ask for factory audit reports (e.g., from SGS or BV), patents for their vibration or control systems, and photos/videos of their production workshop and past custom projects.
Assess Communication: A professional supplier will ask detailed questions about your spec sheet and provide preliminary CAD drawings for your approval.
Get Detailed Terms: Request a Faktur Proforma (PI) that itemizes all costs (machine, customization, spare parts, packaging), details warranty (scope and duration), and clearly states shipping terms (Incoterms like FOB or CIF).

Phase 3: Manufacturing, Inspection, and Shipping

With a contract and deposit in place, the project moves to execution.

Timeline: A custom QT6-15 typically has a lead time of 30-60 days after deposit confirmation.
