Metal Stamping Overview
High-precision stamping solutions for reliable performance and mass production.
Metal stamping uses a press and matched tooling to cut, punch, form, or shapesheet metal into repeatable parts. It is ideal for OEM projects that require stabledimensions, high production efficiency, and consistent part quality across batches.
Flat Blank
Sheet metal blank is prepared according to part design.
Punching
The punch and die cut or pierce the blank to create features.
Forming
The material is formed into the required shape under pressure.
Flanging
or Bending
Edges are flanged or bent to add strength or assembly features.
Finished Part
The stamped part is trimmed, inspected, and ready for assembly.
Types of Metal Stamping
Custom Metal Stamping Built Around Your Drawings
Based on your drawings. part geometry, tolerance requirements, order volume, and lead time, SR MFG selects the most suitablestamping process and die strategy. For suitable production programs,stamping. bending. localized forming, and related operationscan be integrated into a streamlined process flow to reduce handoffs, improve consistency, shorten lead time, andlower per-piece cost by 10-15% (depending on part complexity and production volume).
Single-Operation Stamping
Single-operation stamping uses one press stroke to complete one process, such as punching, blanking, trimming, or simple bending. It is suitable for simple parts, prototype validation, low-to-medium volume orders, or projects that require flexible tooling and faster design adjustments.

Compound Stamping
Compound stamping completes two or more operations in one press stroke, such as punching and blanking, or cutting and localized forming. It helps improve dimensional consistency, reduce secondary handling, and is suitable for parts with stable designs and medium-volume production requirements.

Progressive Die Stamping
Progressive die stamping feeds strip material through multiple stations in one die. Each press stroke completes part of the process until the final part is formed. It is ideal for repeat parts, high-volume production, stable tolerances, and lower per-piece cost after tooling approval.

From basic cutting to complex forming, our stamping capabilities cover a wide range of operations tomeet your product requirements and performance goals.
Punching
Punching uses a punch and die to create holes, slots, or cutouts in sheet metal. It is ideal for ventilation holes, mounting holes, slots, and other functional features.
Blanking
Blanking cuts the sheet or coil material along a closed contour to produce the required flat shape or profile. It ensures clean edges and consistent dimensions.
Flanging
Flanging forms a raised edge along a hole or part perimeter to increase stiffness, improve alignment during assembly, or create surfaces for fastening, sealing, or reinforcement.
Deep Drawing
Deep drawing forms sheet metal into three-dimensional shapes such as cups, enclosures, or housings. It is suitable for parts that require high strength and seamless walls.
Common Types ofStamped Parts
General Tolerance Reference for Metal Stamping
For dimensions without individually specified tolerances, ISO 2768-1 Class m can be used as a generalreference when applicable. Final tolerances depend on part geometry, material thickness, tooling structure,forming complexity, and inspection requirements.
