Manufacturing Services for Custom Parts and Products
Zenbot China coordinates mechanical parts, plastics, electronics and product assembly for projects from prototype review to production. Share your files and requirements so the team can review process fit, inspection needs and delivery scope.
Explore the manufacturing processes
Choose a starting point by material, geometry, quantity and the function of the finished part. A project can combine several processes when the product requires them.
Sheet metal fabrication
Cutting, bending, forming, welding and finishing for enclosures, brackets and assemblies.
Explore sheet metal fabrication3D printing
Additive manufacturing routes for prototypes and complex geometries, with material and finish selection based on the test objective.
Explore 3D printingInjection molding
Plastic part production with tooling, resin, geometry and quantity reviewed together before the process is confirmed.
Explore injection moldingPCB fabrication and assembly
PCB data review, component sourcing, SMT and through-hole assembly, inspection and testing considerations.
Explore PCB and PCBA servicesSupporting processes and assembly
Casting, extrusion, surface finishing, product assembly, testing and packaging according to the project scope.
Explore supporting servicesOEM and ODM projects
Review an existing design or a product concept across mechanical parts, electronics, interfaces and validation needs.
Explore OEM and ODMWhat Zenbot reviews before confirming a route
A process name alone is rarely enough to quote a custom product. These inputs make the technical review more useful.
- Product files and revisionsCAD models, controlled drawings, Gerber data, BOMs and assembly instructions where relevant.
- Material and quantityMaterial grade, finish, color, order quantity and any expected future volume.
- Critical requirementsFunctional interfaces, tolerances, appearance criteria, inspection records and test criteria.
- Schedule and deliveryPrototype, validation and production milestones, packaging and destination requirements.
Guides for the next decision

Read the PCBA guideCommon questions
Can one RFQ include mechanical parts, PCBA and assembly?
Yes. Send the controlled part files, BOM, interfaces, assembly instructions and acceptance requirements together. Zenbot reviews each component and the combined scope before confirming the manufacturing route.
How should I choose between CNC machining and 3D printing for a prototype?
Start with the prototype's test purpose, material, geometry, critical dimensions and expected production process. The process comparison guide explains the tradeoffs.
Are published capability figures guaranteed for every project?
No. Capability figures are planning references. Final specifications depend on the files, material, geometry, quantity and inspection requirements agreed for the project. See the capability guide for context.
Ready for a manufacturing review?
Send the latest files, quantities, material and finish requirements, critical features, inspection needs and target timing. Zenbot will review the project scope before confirming a quotation.
