Manufacturing scope
Your drawing starts the conversation.
The right process depends on geometry, material, tolerance, finish, quantity and target cost. CNC machining and sheet-metal fabrication are treated as distinct manufacturing routes.
CNC Precision Parts
Milled and turned components reviewed against material, tolerances, surface finish and inspection requirements.
Aluminum Housings
Custom enclosures and motor housings for drones, electronics, equipment and product development.
Heat Sinks
Machined or extruded aluminum thermal-management parts with anodizing and secondary operations.
Sheet-Metal Enclosures
Computer cases and equipment covers involving cutting, bending, welding, finishing and assembly.
Prototype & Sampling
Early samples supported when practical, with cost and MOQ dependent on design and manufacturing process.
Low-Volume Production
Small orders can be considered, subject to material procurement, tooling, setup and part complexity.
Hands-on coordination
Support during inspection and factory communication
Sally has accompanied overseas customers during factory visits and inspection activities, helping translate questions, coordinate with factory owners and keep discussions on delivery, deposits and corrective actions moving.
- Drawing and RFQ clarification in English and Chinese
- Sampling, deposit and lead-time coordination
- Buyer factory visits and inspection support
- Communication on issues, rework and delivery decisions
