Hunan Jiashan Hardware Tech, a branch company of J AND R METALWORK, began operations in 2007 in Changsha, Hunan, China. Nearly 17 years of management development and sustained technical improvement have turned the plant into a versatile manufacturing hub able to produce complex, high-tolerance components for demanding global industries.
The facility runs several complementary production lines, so a single project can move from prototype to volume output without changing suppliers:
The workshop owns advanced CNC machines, milling machines, polishing machines and stamping machines. Holding this equipment in-house gives direct control over lead times, surface finishes and dimensional accuracy, and enables the team to design and produce various OEM parts from customer drawings or physical samples rather than depending on outside subcontractors.
| Stage | What Happens |
|---|---|
| 1. Inquiry review | Engineering team evaluates drawings or samples |
| 2. Process planning | DFM feedback and selection of the best machining route |
| 3. Production | Machining, molding, forming and finishing |
| 4. Inspection | Dimensional and surface-finish verification |
| 5. Delivery | Export packing and worldwide shipping |
Jiashan parts are widely used in electric vehicles, solar systems, wind power systems and construction machinery. For the modularity R&D of electric vehicles and solar systems in particular, the company can supply a complete solution that spans design support, prototyping and series production.
Because every process - from 5-axis milling to wire EDM and vacuum casting - is handled internally, the plant can hold tight tolerances and reproduce them across repeat runs. Aluminum extrusion and sheet metal fabrication give the team speed on larger frame and enclosure work, while turning and fasteners take care of the smaller, high-volume details that hold an assembly together. That combination suits renewable-energy and construction-machinery programs in particular, where a single structure often mixes machined, molded and formed parts that must fit first time.
Incoming material, in-process dimensions and finished surfaces are all checked before a part is signed off, so defects are caught at the machine rather than at the customer's dock. Technical improvement has not stopped since 2007; each new project adds knowledge that feeds back into fixturing, tooling and process selection for the next one.
With best quality and best service as its enduring priority, Hunan Jiashan Hardware Tech welcomes overseas engineering and sourcing teams to test its capabilities on their next precision project.
