Types of Precision Stamping Parts at Fortuna Stamping

Precision metal stamping is at the heart of high-volume metal part production. At Fortuna Stamping, the process supports everything from micro-connectors to complex shield structures. With advanced tooling and in-house design, we deliver repeatable quality at tight tolerances.

Every stamped part plays a functional role across industries. Whether you're designing IT enclosures, busbars, spring clips, or contact pins, the choice of stamped form matters. Fortuna offers a broad lineup, each built to match strength, size, and fit requirements.

Choosing the right type begins with understanding what’s available. From lead frames and torsion springs to precision terminals, we cover the entire spectrum. This article explores the types of precision stamping parts we offer and how they serve modern product assembly.

Types of Precision Stamping Parts at Fortuna

When you choose Fortuna, you’re getting more than parts. We provide a complete stamping solution shaped around quality, function, and repeatability. Each stamped product is designed with your exact application in mind, whether it’s electrical, structural, or thermal.

Our precision stamping is capable of handling difficult geometries, thin material thickness, and tight tolerance areas. Whether it is shielding cases or terminals, every component is designed to conform to high standards of fit, finish, and performance. Full material selection, plating, and secondary process control are also offered.

Here are the primary types of precision stamping parts we manufacture:

● Stamping Terminals and Plug Connectors

● Metal Shrapnel

● Lead Frames

● Brackets and Mounting Plates

● Crown Springs and Torsion Springs

● Shielding Cases

● Conductive Sheets

● Copper Busbars

Stamping Terminals and Plug Connectors

Stamping terminals are required to withstand secure, low-resistance electrical contact. At Fortuna, these parts are stamped from high-conductivity copper, phosphor bronze, or beryllium copper, depending on your system design. They find application in battery storage and automotive modules as well as communication devices.

We provide plug connectors with specific characteristics such as locking arms, spring fingers, and pressed contact areas. Every profile is constructed on the basis of close dimensional tolerance so that your terminals can be fitted accurately into housings. We endorse matte tin, nickel, and silver plating, which provide long-life conductivity.

Our terminals offer solid current transfer and mechanical contact regardless of whether you are using them with PCB layouts or inline power assemblies. The manufacturing process is precisely controlled, in terms of shape, finish, and performance, whether stamping or plating.

Metal Shrapnel

Stamped shrapnel parts provide repeat spring action in miniaturised systems. Such components are commonly used in switches, touch response panels, and return mechanisms. Fortuna produces ultra-thin shrapnel shapes in terms of fatigue reliability out of spring stainless or copper alloys.

Our dies form uniform bends and manage curvature on strips as thin as 0.05 mm. The bits bend neatly when subjected to weight and bounce back without bending. We have good springback characteristics between batches - important on repetitively actuated devices.

In cases of more sensitive applications, edge deburring, stress relief, and polishing are also possible. The stamped layers integrate form, flexibility, and fatigue control into our shrapnel parts.

Lead Frames

In electronic packaging, lead frames facilitate assembly at the die level. These stamp-down parts serve as the physical and electrical basis of semiconductors, sensors, and mixed circuits. Each frame is constructed at Fortuna to accommodate wire bonding, solder pads, and thermal paths.

We die stamp on copper-based alloys and iron-nickel combinations based on their strength, solderability, and thermal resistance. Depending on the mounting of the die, you can choose full plating, selective plating, or unplated finishes.

Geometrical considerations of the lead frame are vital to downstream yield. Our stamping operations are able to ensure edge accuracy, tie-bar burr-free, and flatness control. Each frame is primed to bond or trim, or shape, and does not interfere with its uncoated profile tolerance.

Brackets and Mounting Plates

Stamped structural brackets serve to support, position, or shield internal parts. The metal components are used as stiffeners of PCBs, sensors, fans, or displays. We use high-strength press tools in the manufacture of stainless steel or plated iron brackets at Fortuna.

You will be able to specify bends, flanges, embosses, or fastener holes in a single design. We can handle components of complex folds and thickness consistency. Surface treating also uses mounting plates to avoid corrosion in vulnerable sites.

Geometry and material properties of these brackets can be adjusted to suit the tough alignment requirements or shock resistance of the design. We make them to your mounting limitations, as accurately repeatable per piece as you desire.

Crown Springs and Torsion Springs

Our stamped springs offer a small and controlled mechanical response as profiles. The approach of Crown Springs is that they are centrally compressed. Torsion springs: Torsion springs, on the other hand, rotate when they are under load. Both kinds are applied in contact systems, latches, and rotating parts.

Fortuna produces them out of beryllium copper and high-fatigue stainless steel. We flatten the coils, post-form them, and treat the material so that they remember their shape. After thousands of cycles, you still have smooth load-deflection behaviour.

Stamped springs have greater design flexibility compared with the wire-formed counterparts. They can be assembled closer, adjusted better, and scraped more economically in large lots.

Shielding Cases

Shielding cases protect electrical signals from interference. Such enclosures guard circuits against EMI and make devices work as they are supposed to. In Fortuna, all the cases are produced by stamping out of conductive metals such as plated steel or copper-nickel alloy.

We favor one-piece, fold-down, or multi-chamber shields that have grounding tabs. The tight overboard is controlled in all directions and has features of reliable grounding and low contact resistance. We also provide slots or perforations of airflow where necessary.

Whether it's shielding components for mobile devices or routers, or control boards, we have made these to suit your PCB layout and board stack-up. They not only fit, but also work in real electromagnetic conditions.

Conductive Sheets

These stamped parts carry electrical paths, earth planes, or contact areas. They are made of high-conductivity copper or brass and are used in small assemblies where routing of the wire would not be feasible. You will usually find them behind housings, beneath layers or under screw terminals.

We make these sheets flat or shaped and with mounting holes or sticky layers to simplify installation. In areas where board space is scarce, these sheets assist in spreading the charge efficiently. They fit well in embedded systems and stratified electronic structures because of their compact profile.

Copper Busbars

Busbars are used to transfer large currents between critical circuit areas. These stamped bars join power inverters, distribution boards, and energy storage. Fortuna manufactures flat and formed busbars in pure copper with full-length dimensional control.

Holes, bends, and clearance insulations are customised on each busbar. To maximise contact and oxidation resistance, we provide dual-layer plating, so for example, nickel base with tin top. They are well-polished, and the flatness of the surface is inspected on every lot.

High-current control systems cannot exist without busbars. Our process provides you with the structural performance and the conductivity that is required to perform well in the field.

FAQ’s

Q1. Can I get part design support before manufacturing?
Yes, you can. Our engineers review your drawings and provide tooling feedback. We’ll help make your design easier to stamp and more reliable.

Q2. What tolerance can I expect from Fortuna parts?
We typically hold ±0.02 mm on stamped features. If your part needs tighter control, we’ll tailor the tooling and inspection to match it.

Q3. Do you accept small-volume or development orders?
Yes, we do. Whether you’re testing a new product or refining an old one, we support low-volume runs with full process control.
