NMX-BCP-01 · ENGINEERED TO ORDER — BULLET-CUP FORMING PRESS

Double acting blanking & cupping press. Blank and cup, in one stroke.

The first forming stage of a bullet: a double-action press that blanks a disc from gilding-metal strip and deep-draws it into a cup in a single stroke. An outer blank-holder slide controls the metal while an inner punch draws — so the cup comes out concentric and uniform-walled, calibre after calibre. Coil-fed, tooled to the drawing, engineered to order in Noida.

Overview

A bullet starts as a cup.

Before a bullet has a jacket, it has a cup — a small, deep-drawn gilding-metal shell that every later operation depends on. If that cup is off-centre or its wall uneven, no downstream draw or anneal will recover it. So the first press has one job: turn flat strip into a perfectly concentric cup, every time, at production rate.

Representative render — the die station of a double-action press: a wide gold-brass gilding-metal strip across a polished tool-steel die, a cylindrical blank-and-draw punch, and a row of tiny plain empty gold cups beside the pierced scrap strip

Fig · 02 The die station — strip in, blanked and drawn to a cup (representative render)

That is exactly what a double acting blanking and cupping press does. “Double acting” means two slides work together in a single stroke: an outer blank-holder slide comes down first and grips the strip, controlling how the metal flows; then the inner draw punch blanks a disc out of the strip and deep-draws it into a cup in the die. Holding the blank while it is drawn is what keeps the cup concentric and stops the wall from wrinkling or thinning unevenly.

The press is fed from a coil: a decoiler, straightener and roll feed present gilding-metal strip to the die, and the pierced scrap web is stripped and coiled for recovery. Change calibre by swapping the blanking and cupping die set — punch, die and blank-holder — each gauged so the cup form and internal diameter hold the component drawing. The output is cups held to 0.05 mm wall-thickness variation and a controlled dome hardness, ready for the line that follows.

The cup is the datum for everything after it. Getting it concentric here, in one stroke, is cheaper than trying to fix it in every operation downstream.

Mechanism · Double Action

Hold, then draw

The outer blank-holder slide clamps the strip and controls metal flow while the inner punch blanks and deep-draws in the same stroke. That sequence — hold, then draw — is what a single-action press cannot do, and it is why the cup comes out concentric with a uniform wall.

Quality · ≤0.05 mm

Concentric and uniform

Cups are held to a wall-thickness (concentricity) variation within 0.05 mm and a controlled dome hardness of about 65–75 VPN, gauged in line. Cupping-punch wear is watched with a plug gauge and the punch replaced on a tight-fit criterion, so quality does not drift through a run.

Range · 5.56–9 mm

One press, many calibres

Configured for small-arms bullet cups across the 5.56, 7.62 and 9 mm classes in gilding metal to IS 2768. Calibre change-over is a die-set exchange with the feed and stroke re-set to the cup — the same press covers a family of components.

Architecture

Strip in, cup out. One stroke between them.

The schematic below is the forming event as the process defines it — strip, the two slides, the die, and the cup that leaves with its scrap web — with the quality the cup is held to.

Fig · 03 Gilding-metal strip → blank-holder clamps & punch draws → concentric cup + pierced scrap web

Arc · 01

The Double Action

Two slides on one press stroke. The outer blank-holder slide descends first, gripping the strip against the die face so the metal cannot pucker; the inner draw punch then blanks a disc and deep-draws it into the die. Holding the blank throughout the draw is the whole point — it is what turns a flat disc into a concentric, uniform-walled cup instead of a wrinkled one.

Arc · 02

Strip & Feed

A coil feed line — decoiler, straightener and roll feed — presents gilding-metal strip to the die at the right pitch each stroke, so blanks nest efficiently and material is not wasted. After blanking, the pierced scrap web (the strip skeleton) is stripped clear and coiled for recovery, and the formed cups are collected clear of the tooling.

Arc · 03

Tooling & Quality

Quick-change blanking and cupping die sets — punch, die and blank-holder — are built and gauged per calibre so cup form and internal diameter hold the drawing. Cup wall-thickness variation is held within 0.05 mm with a controlled dome hardness; the cupping punch is checked for wear with a plug gauge and replaced on a tight-fit criterion, and cups are gauged in line.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 How is this different from a cartridge-case manufacturing line?

They make different parts of the round. A cartridge-case line forms the brass case that holds the propellant — and typically starts from cups. This press makes the gilding-metal bullet cup: the deep-drawn shell that becomes the bullet’s envelope or jacket. So the two are complementary rather than competing — this is a bullet-component press, upstream of the jacket-forming operations, working in gilding metal to close tolerances on concentricity and wall uniformity. Different metal, different part, different place in the line.

Q · 02 What does “double acting” actually mean here?

It means the press has two slides that act in sequence within one stroke. The outer slide is a blank-holder: it comes down first and clamps the strip against the die, controlling how the metal is allowed to flow. The inner slide carries the draw punch: it blanks a disc out of the strip and pushes it down into the die, drawing it into a cup while the blank-holder still grips the surrounding metal. A single-action press has only the punch, so the metal is free to pucker and the wall thins unevenly. The second, holding action is precisely what gives a concentric cup with a uniform wall.

Q · 03 Why does the cup’s concentricity matter so much?

Because the cup is the datum for every operation after it. It is drawn, trimmed, annealed and re-drawn into a thin, even envelope; if the wall is thicker on one side at the cup stage, that imbalance is carried — and amplified — all the way through, and it shows up as run-out in the finished component. That is why the press holds wall-thickness variation within 0.05 mm and a controlled dome hardness at this first stage, and why the cupping punch is gauged for wear: it is far cheaper to make the cup right once than to chase symmetry through every downstream draw.

Q · 04 Can one press run more than one calibre?

Yes — that is the point of building it around quick-change tooling. The press is configured for a family of small-arms cups in the 5.56, 7.62 and 9 mm classes; to change calibre you exchange the blanking-and-cupping die set (punch, die and blank-holder) and re-set the feed pitch and stroke to the new cup. Each die set is built and gauged to its own component drawing, so the machine holds the right cup form and internal diameter for whichever calibre is running. The mechanism does not change; the tooling and settings do.

Q · 05 What determines the press capacity and rate?

The cup and the output. Press capacity is set by the blanking and drawing force the cup needs — a function of its diameter, wall thickness and the strip material — and the stroke rate is set by the pieces-per-hour the line requires and the feed that can be sustained cleanly. Rather than quote a fixed tonnage, the press is engineered to order: capacity, stroke rate, feed and tooling are configured to your cup range and output, and the rate and quality are demonstrated on your cups at acceptance. Send the cup drawing and the target output and we size it to them.

Q · 06 What is the current status — and what is included?

The press is engineered to order and supplied as a turnkey station. Neometrix builds it to the buyer’s technical specification and delivers the complete installation — the press, the coil feed line, tooling and controls — with installation, commissioning and testing, pre-dispatch inspection, operator training, documentation and warranty, and long-term spares and consumables provisioned.
