Punching & Blanking Services
for OEM Sheet Metal Parts
Feiyu provides punching and blanking services for stamped brackets, mounting plates, clips, tabs, covers, shields, electrical enclosure parts and custom OEM sheet metal components.
OEM Punching & Blanking Capabilities
Feiyu supports overseas OEM customers with punching, blanking, forming, bending, deburring, secondary machining, surface finishing and assembly services.
As an OEM stamped parts manufacturer and metal stamping supplier China partner, Feiyu focuses on punching and blanking services for custom punched metal parts, blanked metal parts and production-ready OEM sheet metal components.
Punching vs Blanking: What Is the Difference?
Punching is used to create holes and openings, while blanking is used to cut the part profile from sheet metal. Many OEM sheet metal parts require both processes.
| Process | Output | Common Features | Typical Parts |
|---|---|---|---|
| Punching | The removed slug is usually scrap; the remaining sheet metal part is the product. | Holes, slots and openings. | Brackets, covers, panels and enclosure parts. |
| Blanking | The cut-out piece is the product; the surrounding sheet is usually scrap. | Flat profiles, plates and stamped blanks. | Parts before bending, forming, welding or assembly. |

Design-for-Manufacturing Support for Punched Parts
Before mass production, Feiyu reviews drawings, hole positions, material thickness, burr risks, bending needs and secondary operations.
Drawing Review
Review geometry, hole position, tolerance and forming requirements.
Identify potential manufacturing risks before production.
Hole & Slot Review
Check hole size, hole spacing and edge distance.
Reduce risk of deformation, burrs or weak features.
Material Thickness Review
Confirm whether the selected material and thickness are suitable for punching or blanking.
Recommend alternatives when needed.
Burr Control Review
Evaluate burr direction, edge quality and deburring requirements.
Help reduce assembly and surface finishing issues.
Secondary Process Review
Review whether parts require bending, tapping, welding, machining or surface treatment after punching and blanking.
Punching & Blanking Manufacturing Workflow
Drawing Review
Engineering reviews drawings, material, dimensions, tolerances, burr requirements and production volume.
Material Selection
Material grade, thickness, coating and mechanical properties are confirmed before production.
Tooling / Program Review
Tooling, punching program, blanking profile and inspection points are reviewed for repeatability.
Punching / Blanking
Holes, slots, openings or blank profiles are produced according to the drawing route.
Deburring
Edges, burr direction and handling-sensitive areas are reviewed and deburred when required.
Bending / Forming if Required
Parts can move into bending or forming when the drawing requires shaped features.
Secondary Machining if Required
Tapping, drilling, machining or welding can be added after punching and blanking.
Surface Finishing
Parts can be plated, powder coated, painted, anodized, brushed or polished.
Inspection
Hole position, profile accuracy, flatness and key dimensions are checked before shipment.
Packaging & Shipment
Final inspection, packing protection and export preparation support overseas delivery.
Quality Control for Punched & Blanked Parts
Feiyu controls punched and blanked parts through material inspection, tooling or program verification, first article checks, in-process inspection and final review.
