You need metal parts with complex bend geometries. But traditional stamping cannot get there without expensive tooling. Costs pile up. Budgets shrink. Lead times stretch.

This is exactly the kind of problem we solve every day at Worthy Hardware.

Fourslide stamping is one of the most effective solutions. It forms metal from four directions simultaneously, completing multiple bends in a single cycle — delivering tight tolerances while keeping tooling costs significantly lower than progressive stamping.

My name is Sandra Gao. I handle engineering consultation at Worthy Hardware and have spent over ten years working on precision metal stamping projects for customers across North America, Japan, Europe, and Australia. I have personally led or contributed to hundreds of stamping projects across these markets. I have seen customers switch from progressive stamping to fourslide and cut their tooling costs by 40% or more. Let me walk you through exactly how it works — and when it makes sense for your project.

What Is Fourslide Stamping?

Fourslide stamping uses four tool-carrying slides that advance from four directions — east, west, north, and south — in a precisely timed sequence. Each slide acts on the metal strip in turn, completing multiple bends within a single machine cycle.

A conventional press stamps from top to bottom. One direction. One action. Fourslide works from four sides simultaneously, enabling bends, twists, and multi-plane shapes that would require multiple separate operations on a standard press.

Here is how the process flows:

  • Metal strip feeds from a coil into the machine
  • A straightener removes any coil curl or distortion
  • The strip enters a blanking station for basic cutting
  • Four slides advance in sequence to complete final forming

Worthy Hardware Fourslide Capabilities:

  • Materials: Aluminum, copper, brass, steel, stainless steel, titanium, alloy steel, bronze, and 100+ metal materials
  • Tolerances: Down to 0.01mm (0.0004")
  • Typical parts: Flat springs, terminals, contacts, clips, brackets, connectors, shields
  • Surface finishing: 50+ options including plating, anodizing, powder coating, and polishing

Real case: I once worked with an electronics engineer from Japan whose part had five bends across three different planes. On a progressive die, that would have meant a complex and costly tool with a development timeline measured in weeks. We solved it on a fourslide machine with one auxiliary cam. He had first samples in hand within days — not weeks.

Benefits of Fourslide Stamping

1. Lower Tooling Costs

Fourslide tooling is built from individual slide tools, each made and adjusted independently. When a design changes, you modify one slide tool — not an entire die set. This keeps engineering changes fast and affordable.

Real case: A procurement manager from Canada had been producing a spring clip through progressive stamping. Tooling costs were high and lead times were long. We recommended switching to fourslide. His tooling investment dropped by approximately 40%, lead times shortened, and part quality consistency improved. He has been placing repeat orders with Worthy for three years.

2. Complex Shapes in One Cycle

Bends over 90 degrees, bends in multiple planes, multiple bends placed close together — fourslide handles all of these in a single forming cycle, with no secondary operations required.

3. Faster Setup and Changeover

Fourslide machines change over faster than progressive die setups. This matters when you are running smaller batch sizes or managing multiple part numbers. At Worthy, we have no minimum order quantity. We support everything from prototype runs to full-scale mass production. Fast changeover keeps per-part costs reasonable even at lower volumes.

4. Better Material Utilization

Fourslide machines work with narrow strip widths and minimal blanking scrap. In many cases, you use less raw material per part compared to traditional stamping — which adds up quickly at higher volumes.

5. Ideal for Small to Medium Parts

For parts up to approximately 75mm wide, fourslide is typically the most cost-effective process. Larger parts require progressive dies or other forming methods. Our engineering team will review your drawing and tell you honestly which process fits best.

6. Consistent, Verifiable Quality

Four-direction forming produces uniform bends cycle after cycle. At Worthy, every outgoing part goes through 100% inspection. We use CMM coordinate measuring machines, optical projectors, and electronic press monitoring systems. Full inspection reports are available with every shipment.

Our quality commitment: If any outgoing part fails to meet drawing specifications, we cover all rework or re-production costs in full — at no additional charge to you. This is not a marketing statement. This is the policy we actually enforce.

How Fourslide Stamping Works: Step by Step

Step 1: Material Feeding

A metal strip coil loads onto the machine. The strip feeds through a straightener that removes any curl or distortion left from coiling. A flat, straight strip is the foundation for accurate parts downstream.

Step 2: Blanking and Piercing

The strip advances into a blanking station. Here, basic outline cuts and hole features are punched into the strip, creating a flat blank — the starting shape for forming.

Step 3: Four-Direction Forming

This is the core of the process. Four slides advance in a precisely timed sequence:

  • Slide one completes the first bend
  • Slide two advances from a different angle for the second bend
  • Slides three and four follow in sequence, completing additional forming features

Each full cycle takes approximately one to two seconds. At steady production speed, thousands of parts are produced per hour.

Critical factor: The timing and positional accuracy of all four slides determines final part quality. Worthy's machines run electronic monitoring systems that track every stroke in real time. Any deviation triggers an immediate alert, keeping tolerances consistently within 0.001mm.

Technical note for engineering buyers: Four-direction simultaneous forming significantly reduces springback. Because each slide can be independently adjusted for cam angle and dwell position, our engineers can precisely compensate for springback based on each specific material type and thickness. This level of compensation is very difficult to achieve on a single-direction power press.

Step 4: Part Ejection

The finished part ejects automatically. The next blank is already advancing into the forming station. The cycle runs continuously.

Applications of Fourslide Stamping

Electronics and Semiconductors

Terminals, contacts, connectors, and EMI shielding clips. These parts require tight tolerances, complex bends, and high-volume consistency. We supply parts for PCB assemblies, battery contacts, and EMI shielding components to customers in Japan, Singapore, and North America.

Automotive

Brackets, clips, retainers, and spring contacts used throughout vehicle assemblies. Automotive production demands consistent quality across millions of parts. Fourslide's cycle-to-cycle repeatability makes it a natural fit.

Aerospace and Defense

Specialty alloys, zero-defect requirements, and full traceability. Worthy provides 100% inspection on all aerospace components, with complete inspection reports and material test reports (MTR) available upon request.

Medical and Dental

Small, precise components in stainless steel and titanium with complex geometries and tight tolerances. Fourslide keeps costs manageable even at the lower volumes typical in medical device development.

Consumer Products

Battery contacts in electronics and toys, clips inside household appliances, spring mechanisms in everyday devices. Small parts, multiple bends, high volumes — this is exactly where fourslide excels.

Lighting

Mounting clips, lamp holders, and contact springs. The lighting industry relies heavily on small stamped components, and fourslide handles them with high efficiency.

Robotics and Industrial Equipment

Custom brackets, lever arms, and flat springs that must perform reliably under load. Our engineering team frequently collaborates with robotics startups to optimize part designs for fourslide production before the first prototype is ever made.

The common factor across all these applications: small parts, multiple bends, and a need for precision. If your part fits that profile, fourslide stamping is likely your best manufacturing option.

When Should You Use Fourslide Stamping?

Use Fourslide When:Use Traditional Stamping When:
Your part has 3 or more bendsYour part requires deep drawing
Part width is within 75mmPart size is larger than 75mm
You need to control tooling budgetDesign is finalized for ultra-high-volume simple parts
Design changes are likelyHeavy forming force is required (500+ tons)
You are in prototype or mid-volume productionMaximum stamping speed is the priority for simple geometries
Part is flat with multiple bend featuresCoining or heavy embossing is required

My simple rule: if the part is small, flat, and has multiple bends — consider fourslide first.

Best suited forSprings, terminals, clips, connectorsLarge brackets, drawn parts, high-strength forming

At Worthy, we run both. Our press capacity covers 5 to 500 tons, and we operate dedicated fourslide machines alongside our progressive die lines. When you send us a drawing, our engineers evaluate which process delivers the best balance of quality, cost, and lead time. In some cases, we combine both: press blanking followed by fourslide forming.

Real case from Australia: A customer came to us with a bracket design, convinced he needed progressive stamping. Our engineering team reviewed the geometry and recommended fourslide instead. Tooling cost dropped by approximately 35%. Part quality was identical. He became a long-term Worthy customer.

Conclusion

Fourslide stamping is one of the most efficient processes available for producing small, complex metal parts. It completes multiple bends in a single cycle, keeps tooling costs low, and allows fast design changes — making it well suited for electronics, aerospace, medical, automotive, and many other industries.

But it is not the right answer for every part. Deep draws, large components, and heavy forming still belong on a power press. The key is matching the right process to your specific part geometry.

At Worthy Hardware, we evaluate every project independently and give you an honest recommendation — even when that recommendation is that fourslide is not the right fit. We believe that straightforward advice is the foundation of long-term partnerships.
