What is Product Assembly?
Product assembly in China means having your product manufactured, assembled, tested, and packaged at a certified Chinese facility. To clarify, we combine the world’s largest component supply chain with skilled labor at a fraction of the cost of European or North American factories. Davantech acts as your complete manufacturing partner: we can source components, produce plastic and metal parts in-house, assemble the finished product, test it, and ship it anywhere in the world under one contract and one roof. We are a One-Stop Shop
Labor and overhead savings of 30–70% compared to Europe or North America without sacrificing quality.
Access to China’s dense component supply chain means faster sourcing and fewer stock-outs.
Component manufacturing, assembly, testing, and packaging handled by a single supplier, eliminating coordination overhead.
From 500-unit pilot runs to multi-million-unit annual production, we scale with your growth.
ISO 9001:2015 processes, incoming inspection, FAI, functional testing, and full traceability on every order.
A single point of contact manages your order from quote to delivery, in English.
In-House Component Manufacturing
We produce injection-molded, insert-molded, overmolded, and CNC-machined parts in our own facility, eliminating the risk of third-party component delays.
Verified Supplier Network
For electronic components, fasteners, cables, and standard hardware, we source from audited Chinese suppliers. Every incoming batch inspected before use.
Prototype to Mass Production
We support your full product lifecycle. Prototype validation, pilot production, and volume ramp-up all managed by the same team under the same quality system.
Custom Packaging & Labeling
Retail packaging, OEM-neutral boxes, branded inserts, or bulk packing. We configure output to match your market and logistics requirements.

Product Assembly in China — FAQs
What types of products can you assemble in China?
We assemble mechanical and electromechanical products and devices, including assemblies that combine CNC-machined parts, plastic housings, cable assemblies, connectors, and integrated electronics.
Do you provide complete box-build and final assembly?
Yes. We support full box-build and final assembly, including sub-assemblies, wiring and cable integration, final fit and finish, functional testing (as specified), and packaging.
Can you source components as part of the assembly service?
Yes. We can support component sourcing based on your BOM and specifications, and we perform incoming checks to verify parts before they enter production.
How do you ensure quality control during product assembly?
Quality control typically includes incoming inspection of parts, in-process checks during assembly, and final inspection or functional testing based on your requirements. Documentation and inspection criteria can be aligned with OEM expectations.
Can you assemble products that include CNC machining, injection molding, and overmolded parts?
Yes. We can integrate CNC-machined components, injection-molded housings, and overmolded parts into complete mechanical or electromechanical assemblies to reduce supplier complexity and improve coordination.
Do you support prototyping and pilot builds before production?
Yes. We support prototype and pilot builds to validate assembly steps, fixtures, test methods, and packaging before moving to low- or mid-volume production.
How do you protect IP and customer design files?
We can work under NDA and handle customer files securely with restricted access for project-specific engineering and production teams.
