Assembly Services
ISTAMPING's assembly services combine precision metal stamping with automated and semi-automated assembly, so parts leave our plant as finished subassemblies. In-die assembly joins components during the stamping stroke itself, while secondary lines handle hardware insertion, riveting, welding, and stacking under one roof.

DFM & ENGINEERING SUPPORT
Design for Manufacturability, Built In
Before tooling starts, our engineers review your drawing for material, tolerance, bend, and volume economics — and lock the process that will hold it across millions of strokes.
What We Review in Your Drawing
Component alignment in automated assembly
Precision tooling, checking fixtures, and vision-guided placement keep stamped components aligned at production rates, protecting joint quality and dimensional consistency.
Joint integrity at high production speed
In-line camera vision and process parameter monitoring catch staking, riveting, and welding defects the moment they appear, protecting the batch and downstream customers.
Mixed-material and insert assembly stability
Material pairing and thermal effects are managed with validated process windows and in-die positioning, so inserts, plastics, and dissimilar metals stay secure across the product life.
DFM to Production Flow
Design the joining die
Complex progressive tooling is built with the capability to join components during stamping production.
Combine stamping and assembly
The punch press simultaneously produces stampings and assembles components in one operation.
Eliminate separate handling
Joining happens inside the stamping stroke, eliminating separate handling and reducing total production time.
Add secondary operations
Semi-automated assembly lines complement in-die joining for parts that need secondary operations.
Ship finished subassemblies
Parts leave the plant as finished subassemblies, verified to the same quality standard as the stampings themselves.

What assembly operations can ISTAMPING perform?
Threading, tapping, staking, riveting, welding, stacking, hardware insertion, in-die joining, and integration with insert molding and overmolding, on automated and semi-automated lines.
What is in-die assembly?
A progressive die that joins components to the part during the stamping stroke, so the press produces and assembles in one operation at up to 300 SPM, cutting total production time.
Can you insert hardware such as nuts, studs, and fasteners?
Yes. Fasteners, screw machine parts, bushings, nuts, studs, plastic pieces, and metal inserts can be joined to stamped parts in-die or on secondary assembly lines.
What quality checks apply to assembled parts?
In-line camera vision systems verify assembled features during production, while CMM and optical measurement confirm dimensions under the IATF 16949:2016 quality system.
Do you handle prototype and low-volume assemblies?
Yes. Semi-automated assembly lines serve prototypes and low volumes, and the same tooling path scales to automated high-volume production.
Why consolidate assembly with stamping?
One supplier manages the full process from strip to finished assembly, eliminating inter-plant logistics, reducing WIP, and giving you a single point of quality accountability.
