What is the main difference between fourslide and progressive die stamping?

Fourslide stamping forms parts using four slides that strike from multiple angles, enabling complex multi-plane bends in a single cycle. Progressive die stamping processes strip stock through a linear series of stations, each performing one operation. The main difference is forming direction: fourslide handles multi-axis bends, while progressive dies handle vertical operations in sequence.

Which process is cheaper for low-volume production?

Fourslide stamping is cheaper for low-volume production. Tooling costs $3,000–$15,000 compared to $10,000–$80,000+ for progressive dies. At volumes under 100,000 parts per year, fourslide typically costs 50–80% less in tooling and delivers competitive per-part pricing.

Can fourslide stamping handle high-volume production?

Yes. Fourslide machines run at 80–400 SPM and support high-volume runs of 500,000+ parts per year. However, progressive die stamping reaches 1,500 SPM and offers longer tooling life (up to 500 million strokes), making it more cost-effective above 1 million parts per year.

What tolerances can fourslide and progressive die stamping achieve?

Fourslide stamping achieves ±0.1 mm typical tolerances on formed features. Progressive die stamping achieves ±0.005 mm on die-ground features such as holes, slots, and edges. Parts requiring sub-0.01 mm tolerances should use progressive die stamping.

Can fourslide stamping replace progressive die stamping?

Fourslide stamping can replace progressive die stamping when the part is a wire form or flat blank with multiple bends in different planes. It cannot replace progressive die stamping for deep-drawn parts, precision-pierced flat parts, or features requiring sub-0.01 mm tolerances.

What parts are best suited for fourslide stamping?

Fourslide stamping is best for clips, springs, contacts, wire forms, antenna elements, and brackets that require bends in multiple directions. Typical industries include automotive (clips, fasteners), electronics (battery contacts, springs), medical (wire forms), and consumer hardware.
