Custom Metal Fabrication Manufacturer for OEM Projects
Yishang supports custom metal projects from drawing review and prototyping through fabrication, finishing, assembly, inspection and repeat production.
We focus on manufacturing customer-defined parts and assemblies around approved drawings, materials, interfaces and finish requirements.

Built Around Custom Metal Projects
Yishang is a China-based custom metal fabrication manufacturer supporting OEM and equipment projects built to customer drawings. Our work covers fabricated sheet metal parts, frames, enclosures, panels, brackets, welded structures and multi-part assemblies across prototype and repeat-production requirements.
Project requirements vary by product, so materials, processes, finishes, interfaces and inspection requirements are reviewed against the approved drawing rather than treated as fixed standards for every project.

One Project May Require More Than One Process
Many custom metal projects combine fabrication, hardware, finishing, machining or other project-specific processes. Yishang reviews the required manufacturing route against the drawing and coordinates the processes needed to deliver the approved component or assembly.
Processes are reviewed and coordinated according to drawing and project requirements.
CNC machining, surface finishing and other project-dependent processes can also be reviewed according to drawing requirements.

Project-dependent processes are reviewed or coordinated according to drawing requirements.
From RFQ to Repeat Production
A clear manufacturing route keeps drawing requirements, sample review, production checks and shipment protection connected.
Review the RFQ
Review drawings, material, quantity, finish and interfaces.
Confirm the Scope
Flag manufacturability issues and confirm scope before quotation.
Review Initial Parts
Review initial parts before repeat manufacturing where applicable.
Manufacture & Inspect
Manufacture to approved requirements and inspect controlled features.
Protect & Repeat
Protect finished components for shipment and repeat orders.
Clear Project Communication
From RFQ through production and shipment, project information stays tied to the approved drawing, quotation and project requirements. Buyers can communicate directly with the Yishang project and sales team as questions arise.
Quality Control Built Around the Drawing
Inspection is aligned with the project-specified material, drawing-controlled features, visible surfaces and approved production requirements rather than a universal tolerance applied to every product.
Material & Purchased Items
Verify project-specified materials or purchased items according to applicable project requirements.
Initial Production
Review drawing-controlled dimensions and project-defined requirements during initial production where applicable.
In-Process Checks
Monitor critical geometry, interfaces and manufacturing requirements during fabrication.
Final Inspection
Inspect specified features and finished components before shipment.
People Behind Your Project
Custom fabrication requires communication between customer requirements, manufacturing, quality and project coordination.
