Custom Handle Shapes and Logos: What to Send Before a Cast Iron Mould Quote

A handle shape and a logo turn a stock cast iron skillet into a new tooling project, and the quote prices the cutting, not the argument that follows. Send a package the factory can measure: dimensioned 2D drawings of the pan body and handle, a STEP or Parasolid model built at finished dimensions, wall-thickness and weight targets, draft and parting-line intent, and logo artwork as vector with a stated relief depth. Then settle three things in writing before money moves: who owns the tooling, who pays for revisions when the first shot misses, and which process assumptions — shrinkage allowance, gating position, pattern layout — the factory applies on your behalf. Buyers who skip the third point meet it in the first sample, and pay for the meeting twice.

What Should You Send the Factory Before Asking for a Mould Quote?

A mould quote is priced off geometry. Anything missing from the drawing becomes the factory’s assumption, and that assumption returns as a change order or as a part you did not design.

Model at finished dimensions: the pan as it sits in the box, not the size the pattern needs to be; the shrink allowance is the factory’s job. Put a tolerance block on the drawing too, because casting tolerances are wider than machining tolerances. For shapes outside a standard range, Meiloz works from buyer drawings and lists size, shape, colour and finish as the customization axes; the quoting steps and fee lines are set out on the cast iron pan manufacturer page.

How Should You Specify the Handle So It Casts Cleanly?

On a one-piece cast skillet the handle shares the pattern with the body, so a handle change is a pattern change. Four items belong on the drawing:

• Attachment geometry. Root radius, and whether the transition is a fillet or a step. A sharp internal corner is a hot spot and the first place a casting cracks.
• Grip cross-section at root, middle and end. A shape that reads well in a render can still be too thin to fill.
• Hanging hole, cast-in or drilled. A cast hole needs core draft; a drilled hole needs a machined pad.
• Symmetry and handing, if the handle is not symmetric.

Draft sits behind most first-shot failures. Every face that has to leave the mould needs an angle, and a hand-drawn curve will carry a vertical wall nobody noticed. If your model has no draft, the toolmaker adds it and you receive a part that no longer matches the drawing, so ask for the draft to be marked and returned for signature before the pattern is cut. Ask too where the parting line lands: the flash line and gate witness come off in polishing, a specified step rather than a given.

Weight goes on the drawing per size, with a tolerance. Meiloz lists seasoned skillets from 6 to 15 inches at 4 to 8 lbs with helper handles and pour spouts — a band across sizes, not a target for yours.

What Logo Format Does the Factory Actually Need?

Vector only: AI, EPS or SVG with type converted to outlines. A JPG forces the factory to redraw your mark, and you inherit their letterforms.

Meiloz lists three routes — engraving, laser and decal — and they are not interchangeable.

• Engraving cuts the mark into the pattern, so the logo is cast in: it survives re-seasoning, but every revision is a pattern revision.
• Laser marks the cast surface after casting: no pattern change, but heavy seasoning can soften the edge.
• Decal is applied and fired; it can carry colour and belongs to the finish specification, not the mould.

Placement decides which route is possible. Meiloz lists four positions: pan bottom, handle, knob and colour box. A bottom logo is usually a pattern insert and can collide with the gate; a handle logo must survive draft; a colour box is a print file.

State the relief depth in writing. A shallow logo fills with baked-on seasoning and becomes a smudge; a deep one can leave a thin section or a witness on the opposite face. Ask for the minimum stroke width the factory can hold, and confirm orientation on the returned drawing: a raised logo on the casting is a recessed logo in the pattern, and a mirrored file cuts a mirrored mark. If the mark sits inside a cooking surface and you sell into the United States, check the current FDA food-contact framework at fda.gov/food, because a recess holds residue. Meiloz states that its cookware meets FDA and LFGB food contact safety standards and that its factory is BSCI-certified.

Who Owns the Mould — and Who Pays When the First Sample Fails?

A mould quote says what the tooling costs. It does not say who owns it, whether it can leave the building, or what happens when the first shots miss the drawing you signed.

Three ownership arrangements are common: buyer pays and owns; buyer pays and licenses the tooling to the factory; factory absorbs the cost into the unit price and keeps ownership. The arrangement matters at the end of the relationship, not the start. Write down where the pattern is stored, who insures it, and whether the factory may use your handle shape for anyone else. A private-label handle that turns up on another buyer’s skillet is a tooling-ownership failure, not a design failure.

Ask what the quote means by a mould: for cast iron the tooling is a pattern set, and a quote for a pattern is not a quote for a pattern plus core box, gauges or a logo insert. The gap surfaces once steel is cut.

Then define failure. “The first shot failed” is not a contract term; a list of measurable conditions is.

• Dimensions outside the tolerance block on a drawing the factory signed — factory, at its cost.
• Short fill, cold shuts, drag marks or a cracked handle root on a correctly drafted drawing — factory tooling correction.
• Zero draft or an undercut the factory did not flag in its manufacturability review — the party that owns the review. Make it explicit, because the default answer is you.
• A logo illegible because the depth you specified was too shallow, or a mirrored logo — buyer’s change, or the party who confirmed orientation.
• A shape you changed after pattern sign-off — you, at the cost of a pattern change.
• Weight outside your stated range but inside standard tolerance — an argument unless both numbers are written before the quote.

Ask for a manufacturability review in writing before the pattern is cut: the draft the factory will apply, the minimum wall it can fill at your weight, where the gate will sit, and every feature it wants to change. A supplier that will not put those four items on paper has told you what the revision conversation will feel like. Then fix how many revision rounds the tooling price includes and what counts as a round.

Which Factory Assumptions Are You Accepting Without Asking?

Three process decisions are made on your behalf on almost every custom casting job. None is secret; all are absent from the quote, and signing without asking makes them yours.

• Shrinkage allowance. Iron contracts as it cools, so the pattern is cut larger than the finished part. If your drawing is at finished size and the allowance is applied evenly, you get the pan you drew; if it is applied to some dimensions and not others, you get a pan slightly off everywhere and out of tolerance nowhere obvious. Confirm that the drawing you sign is the finished part, not the pattern.
• Gating. The gate is where metal enters. It leaves a witness, and on a skillet it is often on the bottom — the same face as your logo. Ask how the witness is removed and whether a bottom logo has to move to clear it.
• Pattern layout. How many pieces share a plate, which way they face, and whether the handle shares the body’s plate. Layout drives cost per piece, weight consistency, and whether one size can run alone.

Casting tolerances are wider than machining tolerances, so a copied machining block is a permanent argument. And a baked vegetable-oil seasoning — the finish Meiloz uses on its seasoned line — adds a layer to the finished dimension, which is why a logo cut to the bare minimum disappears under it. One page of manufacturability notes, returned with your drawing marked up, surfaces all of them.

What Should Be in Writing Before You Pay for Tooling?

These are the clauses worth putting in the tooling agreement.

Check the timetable against the money. Meiloz quotes a new mould at normally 30 days with two samples, a custom production lead time of 4 to 6 weeks, and 35 to 55 days from order confirmation to delivery. Its process is also broken into design at 7 to 15 days, sample confirmation at 15 to 25 days and mass production at 20 to 35 days. Treat those as stage durations, not a sum.

FAQ

How long does a new mould take?

Normally 30 days at Meiloz, with two samples. Custom production is quoted at 4 to 6 weeks and delivery at 35 to 55 days from order confirmation.

Can I send a 3D render instead of a CAD model?

A render shows the look you want and is useless for tooling, because nothing in it can be measured. Send a dimensioned drawing plus a STEP or Parasolid model. If a render is all you have, say so and expect a design fee; Meiloz lists custom design work as a separate cost line.

What if my logo has thin strokes or small type?

Ask for the minimum stroke width the factory can hold at your chosen depth, then adapt the mark. If it has to stay fine, laser or decal may suit better than engraving.

Who keeps the pattern if I stop ordering?

Whichever party the contract names, which is why ownership belongs in writing before tooling payment. If you intend to own it, agree the storage location and its return condition.

What payment terms apply?

Meiloz works on a 40% deposit with the 60% balance before shipment for orders. Confirm how a tooling payment is sequenced against that deposit and what releases it.

Put the drawing package and the written clauses together first, and talk to Meiloz about your mould once both are on the table.
