Assemblies

Assemblies are complete finished products or sub-assemblies built from multiple stamped components joined together - often combining metal stampings with plastic parts, hardware and inserts.

Why Assemblies

Assemblies are complete finished products or sub-assemblies built from multiple stamped components joined together - often combining metal stampings with plastic parts, hardware and inserts.

  • Within our in-die assembly process, presses simultaneously produce stampings and assemble components in one operation, reducing total production time. Stamped parts can also be produced in one operation and then placed in a secondary operation to assemble or insert components. Assembly processes include threading, staking, tapping, hardware insertion, press-fit joining, stacking, welding, riveting and insert molding - so stamped part assembly ships as a tested unit, not a bag of components.
  • By consolidating stamping, managed plating, assembly and insert molding under one quality system, ISTAMPING eliminates tolerance stack-up between vendors and streamlines your supply chain into a single turnkey supplier.
  • From automotive sub-assemblies to EV busbar assemblies with molded housings, we produce high-volume oem metal stamping parts and metal parts assembly with 100% quality assurance and competitive cost.

How We Manufacture Assemblies

1

Design & Engineering

We review the full assembly drawing - stamped components, joining methods, hardware and tolerances - to plan a manufacturing sequence that consolidates stamping, managed plating and assembly under one quality system.

2

Progressive Die Tooling

Precision progressive dies are built in-house to stamp the individual components, with in-die assembly options that join parts in the same press stroke sequence.

3

High-Speed Stamping

Components are stamped in high volume with in-process monitoring, holding ±0.005 mm precision on piloted features before assembly.

4

Secondary Assembly

Threading, staking, tapping, hardware insertion, riveting, welding and insert molding are performed in-die or in dedicated assembly cells with vision-verified joints.

5

Joining Method Selection

Each joint is specified against load, conductivity and cycle requirements: riveting and press-fit for mechanical retention, resistance and laser welding for current-carrying joints, adhesive where dissimilar materials cannot be heat-affected, threaded inserts and bushings where the assembly meets a fastener. Tolerance stack-up across the joint chain is reviewed at DFM, not discovered at first article.

Design-for-Manufacturability Support

Our engineers review your assembly at the quoting stage - component count, joining methods, tolerance stack-up and plating sequence - and recommend design-for-manufacturability adjustments that reduce tooling cost, shorten lead time and improve joint reliability in the field.

FAQ

Questions Buyers Ask

What types of stamped assemblies do you build?

We build multi-component stamped assemblies - terminal and connector sub-assemblies, insert-molded parts, busbar assemblies, and welded or riveted bracket assemblies - combining stamping, plating and secondary operations in one facility.

Can you do insert molding or overmolding on stamped parts?

Yes. We integrate stamped metal contacts and terminals with plastic housings through insert molding and overmolding, producing finished connector assemblies that ship ready for installation.

How do you control quality across multiple components?

Every program begins with a feasibility review and run-at-rate study. In-line camera vision and sensor inspection track each component and the assembled unit, supporting zero-defect, high-volume delivery under IATF 16949.

What are typical lead times for assemblies?

Prototype assemblies can be turned around in 2–3 weeks; production lead times depend on tooling complexity, molding requirements and volume. Send us your drawings for a firm schedule.

How tight are tolerances across a multi-part stamped assembly?

Individual stamped components hold ±0.005 mm on piloted features; the assembly tolerance is the stack of component and joint tolerances, so we run a stack-up analysis at quoting and call out the joints that need in-die or fixture control.
