Lead times depend on the complexity of your requirements: 1-2 weeks for simple sub-assemblies and 3-5 weeks for more complex/multi-component work. It's advisable to specify your expected turnaround times when submitting your sourcing request.
The factories listed on Haizol typically have ISO certification and are accustomed to exporting products that meet international standards. Visual inspection, in-line quality control, and testing records are frequently kept. If you have any special quality requirements, please specify it directly to the factory.

Assembly in manufacturing is the process of joining parts into a subassembly or finished product. It can involve fastening, welding, soldering, wiring, adhesive bonding, testing, labeling, packaging, and documentation. The scope should be defined clearly because assembly can range from simple kitting to full product build.
A general assembly company may handle simple kitting, mechanical assembly, electronics assembly, or a full product build, so the process steps must be clear. Component sourcing, fixture needs, test equipment, packaging requirements, documentation, and similar assembly work help identify the right Chinese assembly factory.
For assembly quotes, include drawings, bill of materials, assembly instructions, supplied and factory-sourced components, testing requirements, labels, packaging, quantity, and inspection standards. This prevents one factory from quoting basic labor while another quotes sourcing, testing, packaging, and final inspection.
