A custom tiller clutch cover lands between USD 0.85 and 1.25 per piece at 50,000 units in 2026, and between USD 1.60 and 2.40 at 2,000. The part is identical in both quotes. What moves is tooling amortisation, and it is the one line most quotes leave out — which makes how much does a stamped clutch cover cost impossible to answer from a price list alone. Kunda Metal quotes tooling separately for exactly that reason, and this is the build-up behind the number.

1. What Does a Stamped Clutch Cover Cost Per Piece?

Five lines make up the price, and only one of them is labour. A 2.5 mm cover weighing about 600 g breaks down like this at a 50,000-piece run.

• Material — USD 0.40 to 0.47. 0.55 kg of 2.5 mm SPCC-SD at USD 0.72 to 0.85 per kg. This is 45 to 55% of the piece price and the only line that moves monthly with the steel index.

• Stamping — USD 0.18 to 0.30. A 5-station progressive die at 60 to 90 strokes per minute, one operator per line, one line running two shifts.

• Deburring and washing — USD 0.03 to 0.05. Tumbling plus a three-stage wash; skip it and the coating adhesion test fails.

• Coating — USD 0.04 to 0.20. Black paint sits at the bottom, zinc plating at USD 0.06 to 0.12, e-coat at USD 0.14 to 0.20.

• Packing, overhead and margin — USD 0.05 to 0.08, plus 12 to 18%.

Sum those and a zinc-plated cover at 50,000 pieces is USD 0.85 to 1.25. At 10,000 pieces the same part is USD 1.15 to 1.65, and at 2,000 it is USD 1.60 to 2.40, because die trial, first-off approval and line setup spread over fewer units. Nothing about the steel or the machine time changed, which is the first reason how much does a stamped clutch cover cost cannot honestly be answered without a volume number attached.

Tooling is where quotes diverge most, and the spread is not arbitrary — it maps to station count:

• Blank-and-form die, single station — USD 2,000 to 4,000, 25 to 30 days. Right for 2,000 to 10,000 pieces a year.

• 3 to 5 station progressive — USD 6,000 to 12,000, 30 to 40 days. The default for a cover with a pierced centre and formed rim.

• 6+ station progressive with cam bending — USD 15,000 to 20,000, 40 to 60 days. Needed when the shoe pocket is drawn rather than pressed.

✅ Bottom line: Material is 45-55% of the piece price and steel index moves it; tooling is the line that swings a quote by 60% at low volume. Ask for both as separate numbers.

2. How Does MOQ Change the Unit Price?

MOQ is not a sales policy — it is the die cost divided by a sensible number of strokes. A USD 9,000 die amortised over 30,000 pieces adds USD 0.30 to every cover. Over 100,000 it adds USD 0.09. That gap is the whole reason most Chinese stamping factories quote a 10,000-piece minimum on new progressive tooling: below it, the die costs more per part than the part costs to make.

Three structures cover most programs, and the right one is decided by annual volume, not by the first order:

• Under 5,000 a year. Compound die at USD 2,000 to 4,000, MOQ 2,000, unit USD 1.60 to 2.40. Accept the higher piece price — that die pays for itself in one season.

• 10,000 to 50,000 a year. 3 to 5 station progressive at USD 6,000 to 12,000, MOQ 10,000, unit USD 1.15 to 1.65.

• 100,000 and above. 6+ station progressive at USD 15,000 to 20,000, MOQ 30,000, unit USD 0.85 to 1.10, with in-die tapping if the cover carries threaded inserts.

Two contract terms decide whether that arithmetic survives year two. Tooling ownership first: the die should be invoiced as its own line, titled to the buyer, with a written right to move it to another press. Die life second: a maintained progressive die for 2.5 mm SPCC runs 800,000 to 1,500,000 strokes before a major rebuild, and the maintenance interval belongs in the contract rather than in a conversation after the first crack shows up.

For a buyer comparing a trading company against a factory, the tell is whether the tooling quote names the station count and the die material. Anyone who answers custom agricultural stamping parts MOQ and tooling amortization questions with one lump sum has not costed the die. Nantong Kunda Metal Products Co., Ltd. runs its own die shop and press lines across 34,778 m² in Haimen District, Nantong, which is why the schedule can be shown piece by piece instead of asserted. For anyone weighing an agricultural machinery parts supplier China OEM custom stamping program against a local press shop, that transparency is the only comparison that holds.

✅ Bottom line: Under 5,000 pieces a year, buy a USD 2,000-4,000 compound die and pay more per part. Progressive tooling only wins once volume clears 10,000.

Frequently Asked Questions

Q: Is a cheaper die a false economy on a 600 g cover?

A: Usually yes, but not for the reason buyers expect. A USD 2,000 single-station die holds the spline within tolerance for 150,000 to 300,000 strokes; a USD 9,000 progressive holds it for 800,000 to 1,500,000 because the guide pillars and stripper plate are heavier. On a part whose failure mode is a 0.3 mm spline drift, die life is the quality specification — and it is the half of how much does a stamped clutch cover cost that never appears on the invoice.

Q: Who owns the tooling after the program ends?

A: The buyer, if the contract says so. Kunda Metal invoices tooling separately, titles it to the customer and will pack and release a die on request. A quote that folds tooling into the piece price is not cheaper — it is a die you cannot audit, cannot depreciate and cannot take with you. Any custom agricultural stamping parts MOQ and tooling amortization schedule worth signing shows the die as its own line.

Q: Do you supply both sample quantities and wholesale volumes?

A: Yes. As an agricultural machinery parts supplier China OEM custom stamping operation, Kunda Metal quotes prototype parts off a laser or a temporary die, then transfers to production tooling once the drawing is frozen. First-article samples typically ship 15 to 20 days after drawing approval, and wholesale quantities run from the MOQ upward without a second setup charge.

Send the Drawing and the Annual Volume

Volume drives the tooling tier, and the tooling tier drives the unit price — so a quote built without an annual number is a guess. Send the drawing plus an expected yearly quantity and Kunda Metal will return two options: the low-tooling structure and the progressive structure, each with its own piece price and break-even volume. OEM and ODM programs, wholesale orders and custom bore or tooth-count variants are all quoted the same way.
